DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings. In FIG. 1, reference numeral 1 denotes a service line from a distribution line to a power consumer, 2 denotes a watt hour meter of the power customer, and 3 denotes a power supply control / confirmation device of the present invention connected in series with the watt hour meter 2. . The power supply control / confirmation device 3 essentially includes a radio signal transceiver 4, a controller 5, and an electromagnetic switch 6; however, in the example of FIG. A simple switch 7 for bypass is provided.

The wireless signal transmitter / receiver 4 includes a wireless signal receiving circuit 8 for receiving a wireless signal via a telephone line, and a wireless signal transmitting circuit 9 for outputting a wireless signal via a telephone line.
A PHS or a mobile phone having the following is used. The controller 5 includes a signal identification unit 10 for identifying a signal from the wireless signal reception circuit 8 and an information processing unit 11. The signal identification unit 10 identifies whether the wireless signal from the remote place is a closing signal of the switch 6, an open signal, or an information request signal for confirming the operation of the switch, and performs information processing. Any of these three types of signals is sent to the unit 11.

The information processing section 11 is connected to the switch control section 12, and when an open signal or an open signal of the switch 6 is input, the information processing section 11 is connected to the excitation circuit 13 of the switch 6 via the switch control section 12. A signal is sent, and the switch 6 is turned on or opened.
When an information request signal is input from the signal identification unit 10 to the information processing unit 11, the information processing unit 11 confirms the operation of the switch 6 via the switch control unit 12, and the contact is turned on. An information signal indicating whether the signal is open or not is sent to the wireless signal transmission circuit 9. The wireless signal transmission circuit 9 outputs a wireless signal via a telephone line, and can check the operation status of the switch 6 at a remote place. In addition, as shown in FIG.
If the meter reading device 14 is installed and the meter reading is input to the information processing unit 11 and transmitted from the wireless signal transmission circuit 9, the meter reading of the watt hour meter 2 can be performed at a remote place. .

As described above, the switch 6 is of the electromagnetic switching type. When the signal from the switch control unit 12 is input to the excitation circuit 13, the switch 6 operates to turn on or open the switch 6. it can. For this reason, if the switch 6 is left open and the switch 6 is turned on by transmitting radio waves to the radio signal transceiver 4 at the date and time designated by the power consumer, power supply can be started by remote control. Conversely, switch 6
Is turned on and the switch 6 is opened by transmitting radio waves to the wireless signal transceiver 4 at the date and time set by the power company, so that power supply can be stopped by remote control. Further, in the present invention, the operation state of the switch 6 is transmitted by transmitting radio waves to the radio signal
, And it is also possible to confirm whether or not the power supply has been started or stopped.

FIG. 2 is a diagram showing control equipment on the power company side. As shown in this figure, a sales office of a power company is provided with a computer 18 having a device registration memory 17,
The power supply start date and time designated by the power consumer is stored together with the telephone number of the PHS or the mobile phone which is the wireless signal transmitter / receiver 4 installed in the power consumer in advance. As the device registration memory 17, for example, a magnetic tape, a magnetic disk, or the like is used. Then, when the date and time comes, the computer 18 automatically calls the telephone number, a radio signal is emitted from the radio wave transmitting station 19 of the telephone company, and power supply is started as described above. Similarly, if the date and time when power supply is stopped is stored in the device registration memory 17, power supply can be automatically stopped.

The PHS or mobile phone has a third
Since the power supply may be started or stopped when a call is made unexpectedly by a user, a counter may be built in the receiving side so that the controller 5 operates only when receiving a plurality of calls. You may keep it. This is because the possibility of calling the same number a plurality of times is small in the case of a wrong call. In addition, a security code can be incorporated to prevent malfunction.

After the power supply is started or stopped in this way, the power supply control / confirmation device 3 is no longer necessary, and it is desired that the power company removes the power supply and allows it to be recovered. . The bypass switch 7 is provided for this purpose. An operator may be dispatched at an arbitrary time after the power supply is started, and the power supply control / confirmation device 3 may be removed after the bypass switch 7 is closed. In this case, the bypass switch 7 will remain on the power consumer side,
As shown in FIG. 3, the bypass switch 7 can be omitted if the connection is made directly by live-line work.

FIGS. 4 and 5 show an uninterruptible bypass tool 20 used for this hot-line work. The uninterruptible bypass tool 20 has energizing heads 22 provided at both ends of a covered wire 21. As shown in FIG. 5, each energizing head 22 has a conducting screw 24 opposed to a hook 23 for receiving an electric wire. Things. In order to directly connect the drop wire 1 and the watt-hour meter 2, these electric wires are fitted to the hook 23, and the handle 25 is operated to rotate the conduction screw 24. Then, the pointed tip of the conduction screw 24 breaks the coating of the electric wire and bites into the internal conductor, so that the lead-in wire 1 and the watt-hour meter 2 can be connected by hot wire work.

[0014]

As described above, according to the present invention, a power supply control / confirmation device is installed at a convenient time prior to starting or stopping power supply to a power customer, and designated by the power customer. The switch can be operated by a radio signal from a remote place at a time or at a designated time set by the power company to start or stop power supply. Whether or not the power supply has been started or stopped reliably can also be confirmed by a radio signal from a remote place. The power supply control / confirmation device is then bypassed when convenient.
After the construction work, it can be removed and used for the next power consumer. For this reason, it is not necessary to dispatch a worker to the site outside of normal business hours as in the related art, which is highly effective for both the electric power consumer and the electric power company.
