  Patent Document 1 discloses a conventional example of a distribution board. The distribution board can be loaded with a plurality of types of circuit breakers (branch breakers) having different voltages, rated currents, and sizes. The voltage and rated current of the circuit breaker for wiring are recorded in association with the branch circuit to which each circuit breaker is connected. The voltage, rated current, and size of the circuit breaker for wiring can be identified based on information printed on a label attached to each wiring circuit breaker and the appearance of the circuit breaker for wiring.

For example, it is initially set to a predetermined arrangement in a factory. On the other hand, the circuit breaker breaker for the distribution board may be recombined by the installer at the site where the distribution board is installed, and after installation, the loading position of the circuit breaker on the distribution board is changed or the wiring is changed. Circuit breakers may be recombined. In such a case, the type of each circuit breaker on the distribution board is visually grasped from each wiring circuit breaker, and is associated with the branch circuit.

  A non-limiting exemplary embodiment of a distribution board system according to the present disclosure includes a distribution board loaded with a plurality of wiring breakers and a plurality of wiring breakers loaded on the distribution board. A memory medium for storing identification information for identifying each type in association with a loading position of each circuit breaker in the distribution board or a branch circuit connected thereto, and a plurality of wiring circuit breakers loaded on the distribution board Each of which includes a read / write circuit that reads the identification information and writes it to the memory medium. This read / write circuit has a detection unit (detector) for reading identification information from a plurality of circuit breakers. Here, the identification information that identifies the type of the circuit breaker for wiring is typically the voltage and rated current of each circuit breaker. If necessary, the size of each circuit breaker and the current measurement terminal Position information, current leakage sensitivity setting value, history of interruption, type of interruption function, interruption voltage value at the time of interruption due to voltage abnormality, and date of manufacture. The identification information may additionally include other information such as management information.

  According to the embodiment having the above-described configuration, the identification information specifying the “type” of each loaded circuit breaker is read by the read / write circuit by the detection unit and written to the memory medium. It becomes possible to correctly grasp the type of the circuit breaker connected to the circuit. In particular, when a circuit breaker is replaced or recombined on the distribution board, it is necessary to update the identification information associated with the position where the circuit breaker related to replacement or recombination is loaded. Conventionally, there has been a problem that this update is forgotten or updated to incorrect information by the installer. However, according to the present embodiment, since the detection unit of the read / write circuit reads the identification information from the circuit breaker mounted on the distribution board, such a problem is avoided.

  In one embodiment, there are a plurality of detection units, and each of the detection units is provided at a position associated with a plurality of circuit breakers on the distribution board. Therefore, the correspondence between the identification information read from the circuit breaker loaded with each of the plurality of detection units and the loading position of the circuit breaker, in other words, the branch circuit to which the circuit breaker is connected Attaching is easily realized. The branch circuit can be identified by, for example, “circuit number” on the distribution board.

  In one aspect, each circuit breaker has an “information carrier” configured so that one of the plurality of detection units can read the identification information. An example of such an information carrier may be an integrated circuit chip (IC chip) configured to transmit a signal indicating identification information to the detection unit in a contact or non-contact manner. Among such IC chips, one from which information can be read without contact is called an “RF tag: Radio Frequency Tag”. An example of the information carrier may be an electric circuit configured to transmit a signal indicating identification information to the detection unit.

  According to the embodiment having the above configuration, since the signal (identification information) is transmitted from the information carrier included in the wiring breaker to the detection unit, the type of the wiring breaker can be acquired quickly and without error. It is. Such an information carrier does not have to be provided directly to the circuit breaker for wiring, and may be provided to an adapter of the circuit breaker for wiring as will be described later.

  Hereinafter, embodiments will be described in detail with reference to the drawings as appropriate. However, more detailed description than necessary may be omitted. For example, detailed descriptions of already well-known matters and repeated descriptions for substantially the same configuration may be omitted. This is to avoid the following description from becoming unnecessarily redundant and to facilitate understanding by those skilled in the art.

  In addition, the inventors provide the accompanying drawings and the following description in order for those skilled in the art to fully understand the present disclosure, and these are intended to limit the subject matter described in the claims. is not.

(First embodiment)
<Basic configuration of distribution board system>
First, a schematic configuration of a distribution board system according to the present embodiment will be described with reference to FIG.

  As shown in FIG. 1, the distribution board system 100 according to the present embodiment includes a distribution board 1 having a main breaker 2 and a branch breaker block 30. The main breaker 2 is connected to a main circuit connected to an external power source (not shown). The external power supply is typically a commercial power supply (power system). The branch breaker block 30 includes a plurality of branch breakers (wiring breakers) connected to a plurality of branch circuits branched from the main circuit. Each of the plurality of branch circuits is connected to the load device 130 via the branch breaker, and supplies necessary power to each load device 130. When the distribution board 1 is a residential distribution board, the load side of the branch circuit is connected to, for example, indoor wiring (power wiring) in the house. Each of the plurality of branch breakers is detachably mounted on the distribution board 1.

  As shown in FIG. 1, the distribution board system 100 includes a read / write circuit 110 and a memory medium 102 connected to the read / write circuit 110. The memory medium 102 stores identification information for identifying the type of each of the plurality of branch breakers loaded on the distribution board 1 in association with the loading position of each branch breaker on the distribution board 1 or a connected branch circuit. It is configured. The read / write circuit 110 is configured to read identification information from each of a plurality of branch breakers loaded on the distribution board 1 and write it to the memory medium 102. Specifically, the read / write circuit 110 includes a detection unit 106 that reads identification information from each of a plurality of branch breakers. Typically, the detection unit 106 is a branch of the distribution board 1. It is provided in the breaker block 30.

  FIG. 2 shows an example of an arrangement configuration of branch circuits in the branch breaker block 30. The numbers from 1 to 20 shown in FIG. 2 are circuit numbers that specify branch circuits. In the example of FIG. 2, ten branch breaker loading positions 3 ′ are allocated above and below a straight line extending from the main breaker 2. In the example of FIG. 2, information indicating which branch circuit is connected to which branch circuit includes the circuit numbers 1 to 20 and the type of branch breaker connected to the branch circuit having the circuit number. Is information that associates. Such information can be expressed as a table as shown in the following Tables 1 to 3, for example.

  In Tables 2 and 3, the symbols “1P”, “2P”, and “3P” are symbols that define the size of the branch breaker and are irrelevant to the function and configuration of the branch breaker. For example, a branch breaker having a size of “1P” may be a branch breaker having a function / configuration indicated by so-called “2P1E”, that is, two poles (Pole) and one element (Element). The codes that can be used to partition the size of the branch breaker are not limited to the above example.

  “Rated current” in Tables 1 to 3 is a value called ampere trip (AT). The identification information that identifies the type of branch breaker may include a value called an amperage frame (AF) that represents the maximum rated current of the branch breaker in addition to the rated current. The “rated current” is necessary for comparing the current with the rated current when the current is measured for each branch circuit. The “voltage” can be used, for example, when calculating power usage based on the measured current.

  In addition, in an energy management system that detects and manages current and power consumption for each branch circuit, each branch circuit is assigned a place name such as “bedroom” or “living room”, “lighting equipment”, “outlet” "Or other device names may be assigned. Such a correspondence between the branch circuit and the location name or the device name is effective for displaying the power usage amount etc. in an easy-to-understand manner for the user in the operation of the energy management system.

  The branch circuit may be connected to a device such as a solar battery, a storage battery, an EV (electric vehicle), a fuel cell, or a hot water supply device incorporating the fuel cell. In that case, naturally, a branch breaker (for example, 3P3E breaker) of a type corresponding to the device is connected to the branch circuit connected to these devices. As information for specifying the “type” of such a branch breaker, information different from a normal branch breaker is effective. For example, a branch breaker connected to a solar power generation device does not require detection of overcurrent or the like. In solar power generation, there is a case where a reverse power flow is performed from the solar power generation device to the commercial current system, and in that case, it is necessary to manage the power flowing in the reverse direction. Thus, for example, a branch breaker connected to a photovoltaic power generation device is required to have a function different from that of a normal branch breaker. A branch breaker having a specific function can also be used for individual power generation devices such as storage batteries and EVs and power storage devices. For this reason, it is effective for energy management to include special information for identifying the type of the branch breaker connected to the photovoltaic power generation apparatus or other devices in the identification information. Therefore, the identification information recorded on the information carrier can include information specifying such a connected device and information specifying a special function corresponding to the connected device (information specifying the type of connected device).

<Example 1 of information carrier of branch breaker>
FIG. 3A is a perspective view illustrating a configuration example of the branch breaker 3 that can be used in the present embodiment, and FIG. 3B is a diagram illustrating a bottom surface of the branch breaker 3.

  The branch breaker 3 in the present embodiment is a circuit breaker called MCCB or MCB (Molded Case Circuit Breaker). The circuit breaker cuts off the power supply from the primary side that opened the circuit when an abnormal overcurrent flows in the circuit (load, circuit) on the secondary side due to factors such as overload or short circuit. A circuit breaker for wiring is a type of circuit breaker used to protect a load circuit and electric wires from damage.

  The branch breaker 3 shown in FIGS. 3A and 3B has an information carrier 35 on which identification information is recorded. The information carrier 35 in this example is an RF tag configured to transmit a signal indicating identification information to the detection unit 106 in a non-contact manner. An RF tag is an element including a memory (storage element) for recording identification information and an antenna for wirelessly transmitting / receiving data in order to perform RFID (Radio Frequency Identification). The RF tag has various names such as an electronic tag, an IC tag, a wireless tag, and an RFID tag. In this application, the term “RF tag” defined in JIS (Japanese Industrial Standard) is used. . The RF tag may include a tag according to the NFC (Near Field Communication) standard and a tag according to various other standards.

  Information can be read from the RF tag by wireless communication at a short distance (several centimeters to several meters depending on the frequency band) using an electromagnetic field or a radio wave. The RF tag which is the information carrier 35 stores identification information for specifying the type of the branch breaker. The size of the information carrier 35 is, for example, 1 mm thick, 1 cm long, and 1 cm wide. This size can be further reduced in the future as the RF tag is realized in the future. The shape of the RF tag that is the information carrier 35 is not limited to a rectangle, but may be a cylindrical shape, a coin shape, a thin film type, a label shape, or a card shape.

  The frequency of wireless communication can be appropriately selected from the bands of medium wave (below 135 kHz), short wave (13.56 MHz), UHF (eg 900 MHz), and microwave (2.45 GHz). Depending on this frequency, the shape and size of the antenna can be selected. Since the wavelength of the electromagnetic wave becomes longer as the frequency becomes lower, in this embodiment, which is preferable to be downsized, a magnetic antenna with a micro loop having a size shorter than the wavelength can be adopted.

<Detection unit of distribution board>
As shown in FIG. 4, the distribution board 1 in the present embodiment is provided with a detection unit (detection element or detection circuit) 106 at a position facing the back surface of the loaded branch breaker 3. Coupling by an electromagnetic field is realized in a predetermined frequency band between the loaded information carrier 35 of the branch breaker 3 and the detection unit 106 located in the vicinity of the information carrier 35. As a result, the identification information recorded in the RF tag that is the information carrier 35 is read by the detection unit 106.

  In the example illustrated in FIG. 4, the plurality of detection units 106 are arranged on the distribution board 1, but only the antenna of the detection unit 106 may be arranged to face each branch breaker. In that case, the wiring drawn out from the plurality of arranged antennas can be connected to one or a plurality of detection circuits provided at any position of the distribution board 1.

<Configuration Example 1 of Detection Unit and Information Carrier>
FIG. 5A is an equivalent circuit in the main part of the information carrier 35 and the detection unit 106.

  In the example of FIG. 5A, the detection unit 106 includes an antenna 152 and a control circuit 156. On the other hand, the information carrier 35 includes an antenna 352, a memory 354, and a control circuit 356.

  When the antenna 152 of the detection unit 106 forms an electromagnetic field around it, power is generated in the antenna 352 of the information carrier 35 located near the detection unit 106 (for example, within a distance range of several centimeters). The control circuit 356 and the memory 354 of the information carrier 35 are operated by the generated power, and necessary processing is executed. As a result, code data including identification information stored in the memory 354 is transmitted to the antenna 152 of the detection unit 106 by electromagnetic coupling between the pair of antennas 352 and 152. The control circuit 156 of the detection unit 106 detects identification information from the received code data. The identification information acquired by the detection circuit 156 is given to the read / write circuit 110 shown in FIG.

  FIG. 5B is an equivalent circuit diagram illustrating an example of a configuration in which the detection unit 106 includes the antenna 152 but does not include the control circuit 156. In this example, a plurality of detection units 106 are connected to one control circuit 156 via a wiring 158. The control circuit 156 acquires the identification information of the branch breaker from the information carrier 35 of the corresponding branch breaker via the antenna 152 of each detection unit 106. In this case, part or all of the control circuit 156 may be provided inside the read / write circuit 110.

  The frequency of electromagnetic waves used for wireless communication of identification information is a factor that affects the distance of wireless communication. An appropriate frequency is selected, and an electromagnetic wave shielding wall is provided around each detection unit 106 as necessary, so that each detection unit 106 erroneously identifies identification information from the information carrier 35 of the adjacent branch breaker 3. Can be prevented from being read. In general, the lower the frequency of the electromagnetic wave, the shorter the distance for wireless communication. However, the wavelength of the electromagnetic wave becomes too long with respect to the size of the antenna, and the transmission efficiency tends to decrease.

<Position variation of information carrier>
FIG. 6A is a perspective view showing another example of the position where the information carrier 35 is provided. The position where the information carrier 35 is provided is arbitrary and does not need to be visible from the outside. Further, as shown in FIG. 6B, a plurality of information carriers 35 may be provided in one branch breaker.

  The position of the detection unit 106 provided in the distribution board 1 is preferably opposed to the position of the information carrier 35 of the branch breaker 3 when the branch breaker 3 is loaded on the distribution board 1. However, if interference of electromagnetic waves does not occur when reading the identification information from the information carrier, it is not necessary that the information carrier 35 of the branch breaker 3 and the detection unit 106 of the distribution board 1 are close to each other in the loaded state. It may be separated by a distance allowing wireless communication.

  In the above example, the detection unit 106 is configured to read the identification information from the information carrier 35, but the detection unit 106 appends data wirelessly to the memory 354 of the RF tag that is the information carrier 35. It is also possible to do. In this case, the memory 354 is not a read-only type but a recordable type or a rewritable type. If an address is given to the branch breaker 3, data other than identification information can be communicated between the antenna 152 of the detection unit 106 and the antenna 352 of the information carrier 35. In this case, the system controller that controls the system can assign an address to each branch breaker 3 and store the address information in the information carrier 35 of each branch breaker 3. For example, when a trip occurs in a certain branch breaker 3, information indicating the cause of the trip is output from the antenna 352 of the branch breaker 3 and can be received by the antenna 152 of the detection unit 106.

  The information carrier 35 is not limited to the RF tag. The information carrier 35 may be an integrated circuit element or an electric circuit configured to transmit an electric signal by contact between terminals. In that case, instead of the antennas 152 and 352, a plurality of terminals are provided in each of the detection unit 106 and the information carrier 35.

<Example 2 of information carrier of branch breaker>
FIGS. 7A and 7B are diagrams showing another configuration example of the branch breaker used in the present embodiment. The branch breaker 3 has an information carrier 35 therein, and three terminals 35 a of the information carrier 35 are exposed on the bottom surface of the branch breaker 3.

  As shown in FIG. 8, the distribution board 1 in the present embodiment is provided with a terminal 106 a of the detection unit 106 at a position facing the terminal 35 a on the bottom surface of the loaded branch breaker 3. When the terminal 35a of the loaded branch breaker 3 comes into contact with the terminal 106a of the detection unit 106, the identification information recorded on the information carrier 35 is read by the detection unit 106.

<Configuration Example 2 of Detection Unit and Information Carrier>
FIG. 9 is an equivalent circuit diagram of the information carrier 35 and the detection unit 106 in the examples of FIGS. 7 and 8. In the example illustrated in FIG. 9, the detection unit 106 includes three terminals 106 a, 106 b, 106 c, a voltage source 162, and a voltage measuring device 164. The information carrier 35 is an electric circuit, and has three terminals 35a, 35b, and 35c and two resistors R1 and R2. The resistor R1 connects the terminal 35a and the terminal 35b, and the resistor R2 connects the terminal 35b and the terminal 35c.

  When the three terminals 106a, 106b, and 106c of the detection unit 106 come into contact with the three terminals 35a, 35b, and 35c of the information carrier 35, the voltage source 162 passes through the two terminals 106a and 106c. A voltage is generated between the two terminals 35a and 35c. The magnitude of the voltage generated between the terminals 35a and 35b varies depending on the ratio of the resistors R1 and R2. For example, when the voltage source 162 applies a voltage of V0 volts between the two terminals 35a and 35c, a voltage of V0 × R1 / (R1 + R2) volts is generated between the terminals 35a and 35b. Since the voltage generated between the terminal 35a and the terminal 35b is detected by the voltage measuring device 164 of the detection unit 106, the value of R1 / (R1 + R2) can be detected.

  If a set of identification information is classified in advance and a different value of R1 / (R1 + R2) is assigned to each set, the corresponding value is determined based on the voltage value measured by the voltage measuring device 164 of the detection unit 106. A set can be determined. For example, when a set of two values of voltage and rated current is classified as (voltage, rated current) = (100V, 15A), (100V, 20A),..., (200V, 50A), Different values of R1 / (R1 + R2) may be assigned to each of the classified sets. As a result, identification information (in this case, “voltage” and “rated current”) of the information carrier 35 can be acquired by the detection unit 106.

  In the above example, the expression of the identification information included in the information carrier is analog and the amount of information is relatively small. However, if one information carrier 35 has a plurality of configurations shown in FIG. 9, the number of terminals increases, but the amount of information that can be stored also increases. In that case, the number of terminals of the detection unit 106 also increases.

  In addition, it is not necessary to provide the voltage source 162 and / or the voltage measuring device 164 in each of the plurality of detection units 106, and the terminals 106a, 106b, and 106c in the plurality of detection units 106 include one voltage source 162 and / or 1 What is necessary is just to be connected to the voltage measuring device 164 by wiring. In that case, a switch is inserted in the middle of the wiring, and the operation of each detection unit 106 can be switched and executed.

<Read / write operation>
Refer to FIG. 1 again.

  With the configuration described above, the identification information read by the detection unit 106 from the information carrier 35 of the branch breaker 3 is written into the memory medium 102 by the action of the read / write circuit 110. Such reading / writing of the identification information is not only performed when the distribution breaker 1 is loaded on the distribution board 1 before shipment, but also when the distribution breaker of the distribution board 1 is recombined by the operator after shipment. Can also be implemented. Also, when at least one of the plurality of branch breakers loaded in the distribution board 1 is replaced with another branch breaker, the read / write circuit 110 identifies information for identifying the type of the branch breaker after replacement. And the identification information recorded in the memory medium 102 is automatically updated.

<Variation of distribution board>
The configuration of the present embodiment is not limited to the example shown in FIG. FIG. 10A is a block diagram illustrating a configuration example in which both the memory medium 102 and the read / write circuit 110 are provided in the distribution board 1. On the other hand, FIG. 10B is a block diagram illustrating a configuration example in which the memory medium 102 is provided outside the distribution board 1 and the read / write circuit 110 is provided in the distribution board 1. As described above, in the distribution board system 100 according to the present embodiment, the degree of freedom of the arrangement configuration of the distribution board 1, the memory medium 102, and the read / write circuit 110 is high, and a part or all of the read / ride circuit 110 is configured. It may be included in a part of another circuit unit (not shown).

  The memory medium 102 may be a medium removable from the read / write circuit 110, or may be a storage element built in the read / write circuit 110. Examples of the memory medium 102 may be a non-volatile semiconductor storage device, a memory card, an optical disk, and a hard disk.

  Note that a part or all of the memory medium 102 and the read / write circuit 110 are located away from the position where the distribution board 1 is installed, and are connected to the distribution board 1 via a local area network or the Internet. May be. In addition, the memory medium 102 may be a part of a data storage device placed in a data center.

  Information recorded in the memory medium 102 can be used for various purposes. For example, if the rated current of the branch breaker 3 loaded in the distribution board 1 is acquired based on the information recorded in the memory medium 102, the detection is performed by detecting the current flowing through each branch circuit. It is also possible to display on the monitor in real time how much the value of the current value is with respect to the rated current of the branch breaker 3.

<Basic configuration of energy management system>
First, referring to FIG. An energy management system 1000 shown in FIG. 11 includes a distribution board system 100, an energy measurement unit 190 connected to the distribution board system 100, and a terminal 120.

  In the distribution board system 100, the branch breaker block 30 includes a current sensor unit 4 that detects the value of the current flowing through each branch breaker in addition to the detection unit 106. The distribution board 1 in this example includes a measurement control unit 5 and a data transmission unit 180. The measurement control unit 5 is connected to the detection unit 106 and the current sensor unit 4 in the branch breaker block 30, reads identification information specifying the “type” of the branch breaker connected to each branch circuit, and each branch circuit Can be detected. In other words, the measurement control unit 5 in this embodiment also serves as the read / write circuit 110. Note that the read / write circuit 110 may be provided separately from the measurement control unit 5. The data transmission unit 180 obtains the current measurement value and the identification information from the measurement control unit 5 and gives them to the energy measurement unit 190. The data transmission unit 180 in the present embodiment incorporates a memory medium that records identification information for identifying the type of branch breaker and information indicating the correspondence relationship between the branch circuits. The measurement control unit 5 and the data transmission unit 180 do not need to be provided separately, and may be integrated into one unit.

  The energy measurement unit 190 can transmit and receive data necessary for calculating the power usage amount for each branch circuit via the data transmission unit 180.

  In the present embodiment, current measurement for each branch circuit is performed by the current sensor unit 4 provided in the branch breaker block 30, and measurement data is sent from the branch breaker block 30 to the energy measurement unit 190. On the other hand, the current flowing through the main breaker 2 is measured via a current sensor (not shown) (for example, main current transformer), and the measurement result is sent directly to the energy measuring unit 190. A typical example of the energy measurement unit 190 includes a communication interface, and can transmit and receive data to and from other devices by wire or wireless.

  The current measurement for each branch circuit does not need to be performed according to the above configuration example. Even if a current sensor (for example, a branch circuit current transformer) is set for each branch circuit, the measured value is obtained from each current sensor. Good. In that case, the current sensor set for each branch circuit is connected to the energy measurement unit 190 via a connector and a cable for a current transformer, and the output of each current sensor can be directly supplied to the energy measurement unit 190.

  In the present embodiment, the distribution board 1 is connected to the energy measurement unit 190, but the distribution board system 100 of the present disclosure is not limited to such an example. A circuit block that executes a part or all of the functions of the energy measurement unit 190 may be provided inside the distribution board 1. The energy measurement unit 190 may be connected to a home gateway (not shown) constituting the energy management system by wire or wirelessly.

  The terminal 120 including the display panel can transmit and receive data to and from the energy measurement unit 190 by wire or wireless. On the terminal 120, based on the data acquired from the energy measurement unit 190, for example, the current value or the past value is graphically displayed in a table or graph with respect to the power consumption for each branch circuit and the total power consumption. A program or application configured to be installed. Such a terminal 120 may be, for example, a general-purpose mobile phone, a smartphone, a tablet, a television set, or a personal computer, or a dedicated monitor that forms part of a power measurement system or an energy management system. It may be a terminal (for example, a HEMS monitor).

  The terminal 120 has a built-in interface for receiving user input. This interface may include, for example, a touch screen that displays predetermined icons or buttons, or may include buttons or dials prepared as hardware around the display panel.

  Based on the information stored in the memory medium 102, the terminal 120 displays, for each branch circuit, all or a part of the identification information that identifies the type of branch breaker connected to each branch circuit. It is also possible.

  Although the terminal 120 in this embodiment directly transmits and receives data to and from the energy measurement unit 190, the terminal 120 may perform data transmission and reception via a gateway.

<Arrangement example of branch breaker loaded on distribution board>
FIG. 19 is a plan view schematically illustrating an arrangement example of the branch breakers 3a, 3b, 3c, 3d, 3e, 3f, 3g, and 3h loaded in the distribution board 1 in the present embodiment. Each of the branch breakers 3a to 3h basically has the configuration shown in FIG. 18, but the types (voltage, rated current, and size) are various.

  The branch breakers 3a and 3f in this example are “1P size”, and the rated current is any one of 15A, 20A, and 30A. In the LED display unit 6, the LED 6a indicating the “state” of the branch breakers 3a and 3f is located at a position facing the loading position of the branch breakers 3a and 3f, respectively.

  The branch breakers 3b and 3g are “2P size”, and the rated current is either 40A or 50A. In the LED display unit 6, the LED 6a indicating the “state” of the branch breakers 3b and 3g is on the left side of the branch breakers 3b and 3g at positions facing the loading positions of the branch breakers 3b and 3g, respectively. The LED 6b on the right side as viewed from the branch breaker at a position facing the loading position of the branch breakers 3b and 3g is always in a non-lighting state.

  The branch breakers 3c and 3h are “2P size” and are AA breakers. In the LED display unit 6, the LED 6a indicating the “state” of the branch breakers 3c and 3h is on the right side when viewed from the branch breaker at a position facing the loading position of the branch breakers 3c and 3h. The LED 6b on the left side as viewed from the branch breaker at a position facing the loading position of the branch breakers 3c and 3h is always in a non-lighting state.

  The branch breakers 3d and 3e are “3P size”, which are a gas power generation breaker and a solar power generation breaker, respectively. In the LED display unit 6, the LED 6 a indicating the “state” of the branch breakers 3 d and 3 e is on the left side when viewed from the branch breaker at a position facing the loading position of the branch breakers 3 d and 3 e.

  Thus, the arrangement of the LEDs 6a indicating the “state” of each branch breaker differs depending on the type of branch breaker, because the current path measured by the current sensor unit 4 differs depending on the type of branch breaker. It is. The LED 6a indicating the “state” of each branch breaker is located immediately above the operating current sensor 40. In the case of a branch breaker of 2P size or more, it is necessary to determine which of the plurality of current sensors 40 included in the current sensor unit 4 should detect the current of the branch circuit according to the type of the branch breaker. There is.

  According to the present embodiment, since the detection unit 106 detects identification information that identifies the type of branch breaker, the current sensor used by the measurement control unit 5 to determine the “state” of each branch breaker based on the identification information. Is selected without error. As a result, the “state” of each branch breaker 3 a to 3 h is appropriately displayed on the LED display unit 6.

  In addition, while displaying the "state" of each branch breaker 3a-3h on the LED display part 6, it can be displayed on another display monitor (for example, monitor of the terminal 120) via the energy measurement unit 190 of FIG. it can. Thereby, “visualization” of the amount of electricity used is realized even at a location away from the distribution board 1.

  When the branch breaker 3 is large and loaded, when one branch breaker 3 faces a plurality of current sensors 40, information on which position the current is measured is “position information of current measurement terminal”. Can be added to the identification information.

<Current sensor unit>
Next, the current sensor unit 4 will be described with reference to FIG. 20A shows the appearance of the front surface of the current sensor unit 4, FIG. 20B shows the appearance of the back surface of the current sensor unit 4, and FIG. 20C shows the front view of the current sensor unit 4.

Near the center of the printed circuit board 41 in the short direction, a plurality of second insertion holes 42b through which the branch bars 72c and 73c pass are arranged in parallel.

  The current sensor 40 is, for example, a Rogowski type air core current transformer 45 having a toroidal coil and a rewinding coil. The coil constituting the air core current transformer 45 is formed in the periphery of the first insertion hole 42a so as to surround the insertion hole 42a. These coils are composed of a metal foil pattern 43 provided on the front and back surfaces of the printed circuit board 41, a through hole 44 that penetrates the printed circuit board 41 and connects the metal foil pattern 43, and the like.

  Since the current sensor unit 4 in the present embodiment can be disposed between the base stand 71 and the branch breaker 3, the distribution board 1 can be reduced in size.

  A signal processing circuit 46 and a transmission circuit 47 are provided for each of the two current sensors 40 on the other end side in the short direction of the printed circuit board 41. The signal processing circuit 46 samples the detection currents of the two current sensors 40 alternately by time division, performs processing such as amplification, and the transmission circuit 47 converts the output signal of the signal processing circuit 46 to digital. The printed circuit board 41 is provided with an information transmission path 48 for transmitting input / output signals of the signal processing circuit 46 and the transmission circuit 47, and a power supply path 49 for supplying DC power. The information transmission path 48 and the power supply The path 49 is connected to a connector 95 provided at the end of the printed circuit board 41. The connector 95 is connected to the transmission path 9, and an output signal is transmitted to the measurement control unit 5. In the current sensor unit 4, the branch bars 72 b and 73 b are penetrated through the first insertion hole 42 a, and the branch bars 72 c and 73 c are penetrated through the second insertion hole 42 b. Since the current sensor 40, the signal processing circuit 46, and the information transmission path 48 are disposed on the printed circuit board 41, the detection signal can be transmitted with high reliability, and the distribution board 1 can be reduced in size. Can do.

  The detection unit 106 may be disposed not in the main bars 72 and 73 but in the current sensor unit 4. As described above, since the printed circuit board 41 of the current sensor unit 4 is provided with the signal processing circuit 46 and the transmission circuit 47 for the current sensor 40, it is efficient to use these for the operation of the detection unit 106. Is. When the detection unit 106 includes an antenna for RFID, the antenna can be formed on the printed circuit board 41 by patterning a conductive thin film.

  The measurement control unit 5 stores in the memory medium the rated current value of the branch circuit that serves as a reference when displaying on the LED display unit 6. The measurement control unit 5 has a control circuit inside, and performs the above-described display on the LED display unit 6 and the terminal 120 based on the data detected by the current sensor unit 4 and the above-described rated current value. The measurement control unit 5 includes a power supply unit inside, receives power from the outside, and supplies DC power to the control circuit, the current sensor unit 4, and the LED display unit 6.
