Description

An embodiment of the present invention relates to the main body of an uninterruptible power supply system.

An uninterruptible power supply system (UPS) is a system that supplies electric power of the same standard to a load for a predetermined time even if a power supply trouble occurs. An uninterruptible power supply system usually includes a main body and its peripheral panel, and is installed in a data center or the like. The main body is the main part of the uninterruptible power supply, and includes a rectifier that converts AC to DC and an inverter that converts DC to AC. The peripheral board is an input transformer board, a storage battery board, or the like.

The main body and the peripheral panel are generally housed in a substantially rectangular parallelepiped housing. These housings are often arranged in a row along the wall surface of a data center or the like. Further, the housing of the main body and the housing of the peripheral panel have the same depth dimension and height dimension from the viewpoint of aesthetics. The size of these housings is, for example, a depth dimension of about 100 cm and a height dimension of about 190 cm.

A door is attached to the front of the housing such as the main body, and the door is opened to perform maintenance and inspection of the inside of the main body or the inside of the peripheral panel. Therefore, a work space is provided in front of the main body and the peripheral panel. In addition, the main body and peripheral boards are updated by the end of their expected lifespan. Updating the main body and peripherals means replacing the main body and peripherals with new ones.

The expected life length differs between the main body and the peripheral board, and the implementation time of the replacement work of the main body and the replacement work of the peripheral board are significantly different. Specifically, the expected life of the main body is about 15 years, and the replacement of the main body is based on 15 years after the delivery of the uninterruptible power supply system. On the other hand, the expected life of the peripheral board is about 25 years, which is about 10 years later than the replacement time of the main body.

Japanese Unexamined Patent Publication No. 2014-222982

As mentioned above, the replacement work of the main body must be carried out 10 years earlier than the peripheral board. Therefore, when the main body is replaced, the connection between the main body and the peripheral panel is disconnected, but the peripheral panel itself is still installed. Therefore, in the replacement work of the main body, only the main body to be replaced should be removed from the fixed installation location from the group of housings lined up in a row, and the new main body should be re-installed in the same location. become.

Since such replacement work of the main body covers the entire main body, many construction facilities such as a gate-shaped construction facility that covers the main body and a horizontal pulling hook that hangs on the main body are indispensable. .. Therefore, the replacement work of the main body is a large-scale work, and the work time is prolonged.

In addition, since there is not enough space in a data center or the like, the work space provided in front of the main body is originally small. In addition, the space available for housing replacement work will be significantly reduced when considering the introduction of construction equipment. Therefore, it is extremely difficult to replace the main body in the state of the housing, and there is a problem that the work efficiency of the construction work is low.

Further, considering the role of UPS, the shorter the construction period of the replacement work of the main body, the better. Therefore, it is necessary to concentrate a large number of workers for the replacement work of the main body, and the labor cost has risen. As a result, in the replacement work of the main body, the construction cost including the labor cost is increased, and the renewal cost of the main body is increased.

Of course, there was a request to suppress the increase in the renewal cost of the main body, but there was also a request to extend the renewal time of the main body as much as possible. However, if the main body is used continuously until the expected life is exceeded, there is a high possibility that a problem will occur in the main body. If a defect occurs in the main body, the effect may extend to the peripheral panel connected to the main body.

For this reason, for example, if the main body is used for a long time exceeding the expected life of 15 years, not only the main body but also the peripheral discs that have not reached the expected life of 25 years may be forced to be replaced. .. The scale of the replacement work for the peripheral panel becomes very large, and extending the renewal period of the main body may actually increase the financial burden.

In view of the above situation, it can be said that surely updating the main body by the expected life leads to a total reduction in the running cost of the entire system. Therefore, there has been a strong demand for reducing the cost of updating the main body. In particular, in recent years, the renewal market for the main body has been expanding along with the spread of data centers, and there is an urgent need to reduce the cost of updating the main body.

In addition to the above-mentioned issues when updating the main body, it takes a considerable amount of time to carry out maintenance of the main body, replacement with an alternative machine, etc., and the construction cost is high. The point becomes an issue. In addition, it is often difficult to secure a space because the work is carried out while leaving the peripheral panel during these works.

As mentioned above, in the uninterruptible power supply system, it was explained that there is a difference in expected life between the main body and the peripheral panel, but there are many cases where there is also a difference in expected life between the main unit and the peripheral panel in other power supply panels. Therefore, there is a similar problem.

This embodiment has been proposed to solve the above problems, and the purpose is to easily carry out replacement work of the main body portion by attaching and detaching the main body portion to and from the frame body portion as it is. The purpose of the present invention is to provide a power board for reducing the cost of updating the main body. Another purpose is to provide the main body of an uninterruptible power supply system that facilitates replacement work and reduces renewal costs.

In order to achieve the above object, the embodiment of the present invention is a main body for configuring an uninterruptible power supply system, in which at least one of a rectifier and an inverter is provided and mounted in a direction upright with respect to an installation surface. When the housing is electrically connected to at least one of the rectifier and the inverter, and the housing is mounted on the installation surface, the input transformer panel, possess to the connection portion electrically connected to the peripheral board is at least one battery plate and branch board, and the body-side connecting portion arranged to be electrically connected, and the body-side connecting portion to the connecting portion, Ru movable der the retracted position to the joining position and disengage the junction.

The main body 1 and the peripheral boards 6 to 8 are housed in a substantially rectangular parallelepiped housing, and are arranged in a row along a wall surface of a data center or the like. Doors are installed in front of each housing in the main body 1 and the peripheral boards 6 to 8, and the doors are opened to perform maintenance and inspection of the main body 1 or the peripheral boards 6 to 8.

In FIG. 1, the input transformer board 6, the main body unit 1, the branch board 8, and the storage battery board 7 are installed in this order from the left side of the drawing. Further, the main body UPS1 is provided with a display unit 10 at a height of 100 cm or more from the bottom surface portion. In FIGS. 1 and 2, the main body 1 is shown lower than the peripheral boards 6 to 8, but this is to clarify the difference between the main body 1 and the peripheral boards 6 to 8, and the main body 1 and the peripheral boards 6 to 8 are shown. The height dimensions of the peripheral boards 6 to 7 may be aligned.

The power panel according to the first embodiment is provided with a frame body portion 4 that supports the main body portion 1 so as to surround the main body portion 1 from the left and right and from below. In FIGS. 1 and 2, the inner portion shown by the dotted line is the main body portion 1, and the outer portion of the dotted line is the frame body portion 4. As shown in the side view of FIG. 3, the main body portion 1 is arranged with respect to the frame body portion 4 in the state of the housing, that is, the entire housing can be pulled out without disassembling the housing. .. As shown in the perspective view of the main part of FIG. 4, the frame body portion 4 has no upper surface portion, and includes a bottom surface portion, left and right side surface portions, and a back surface portion connecting the side surface portions.

As shown in FIGS. 3 and 4, a main body side connecting portion 5a is provided on the upper portion of the back surface portion of the main body portion 1, and a frame side connecting portion 5b is provided on the upper portion of the back surface portion of the frame body portion 4. These connecting portions 5a and 5b are arranged so as to face each other, and are electrically connected by joining. Further, although not shown, the frame-side connecting portion 5b is electrically connected to a predetermined portion of the peripheral boards 6 to 8. The main body side connecting portion 5a and the frame side connecting portion 5b are configured to be arranged at positions where the connecting portions 5a and 5b can be joined by pushing the main body portion 1 into the frame body portion 4.

FIG. 5 is a circuit diagram of an uninterruptible power supply system incorporating the present embodiment. The uninterruptible power supply system shown in FIG. 5 is a common standby uninterruptible power supply system, and one spare machine 1a and a plurality of (three in FIG. 5) regular machines 1b are provided as the main body 1. .. As shown in the circuit diagram of FIG. 6, the main body 1 is provided with a rectifier 2 that converts alternating current to direct current and an inverter 3 that converts direct current to alternating current.

(Replacement work of the main body)
In the first embodiment as described above, it is possible to replace the main body 1 by pulling out and pushing the main body 1 from the frame 4 while keeping the housing. When removing the main body 1 from the frame body 4, for example, as shown in FIG. 3, the upper part of the housing of the main body 1 is manually moved by a worker to the front side, that is, the front side of the main body 1 (FIG. 3). By tilting it shallowly and diagonally (on the left side of), the bottom surface of the main body 1 is lifted from the frame body 4. Subsequently, the worker raises the main body 1 perpendicularly to the floor surface while sliding the lower part of the housing of the main body 1 toward the front side (left side in FIG. 3). Then, the worker slides the entire main body 1 toward the front side while maintaining the vertical state of the main body 1 and pulls out the entire main body 1 from the frame body 4.

When the main body 1 is attached to the frame body 4, for example, as shown in FIG. 4, with the housing of the main body 1 facing the front of the frame body 4, for example, two workers are required. Push it into the frame body 4. When carrying out the replacement work, a member (not shown) for smoothly sliding the main body 1 is installed on the bottom surface of the main body 1, for example, a roller.

(Action effect)
In the present embodiment as described above, the main body 1 has a housing that accommodates a rectifier 2 that converts alternating current to direct current and an inverter 3 that converts direct current to alternating current, and is mounted in an upright direction with respect to the installation surface. It has a frame body portion 4 that surrounds the back surface portion and both side surface portions of the front surface portion, the back surface portion, and both side surface portions of the housing, and is attached and detached by pushing and pulling out the housing.

Therefore, since the main body 1 can be easily attached to and detached from the frame body 4 in the state of the housing, the replacement work of the main body 1 can be easily performed. Further, since the work can be carried out by pulling out from the frame body portion 4 even at the time of maintenance of the main body portion 1, the work efficiency is improved.

Further, in the present embodiment, the main body portion 1 and the frame body portion 4 are provided with the main body side connection portion 5a and the frame side connection portion 5b, respectively, and these connection portions 5a and 5b are from the frame body portion 4 to the main body portion. By pulling out 1, the joint state of the two is released, and by pushing the main body 1 into the frame body 4, the two are joined.

Therefore, in the replacement work of the main body portion 1, the work of disconnecting the connecting portions 5a and 5b and the work of joining the main body portion 1 can be performed at the same time as the work of attaching and detaching the main body portion to the frame body portion 4. Moreover, since the main body side connection portion 5a and the frame side connection portion 5b are provided above the main body portion 1 and the frame body portion 4, the connection portions 5a and 5b do not interfere with the attachment / detachment of the main body portion. Therefore, the replacement work of the main body 1 can exhibit excellent work efficiency.

Further, when the main body 1 is replaced, construction equipment such as a gate type and a horizontal pulling hook is not required, and a large space for replacing the main body 1 can be taken. Therefore, the main body 1 can be replaced as it is, and the replacement work can be performed quickly and easily. As a result, the construction cost of the main body 1 can be significantly reduced.

That is, according to the present embodiment, the economic burden at the time of updating the main body 1 is reduced, so that the replacement of the main body 1 can be promoted, and the main body 1 is used beyond the expected life. It is possible to prevent problems that occur in the future. As a result, the peripheral boards 6, the storage battery board 7, and the branch board 8 are not affected by the malfunction of the main body 1, and can reach the expected life. As a result, the total running cost of the entire uninterruptible power supply system is reduced, and the economic efficiency is improved.

Further, in the present embodiment, the display unit 10 is arranged at a height of 100 cm or more from the bottom surface portion of the main body portion 1. Therefore, when the main body 1 is pushed into the frame 4, the worker's hand or the like does not hit the easily damaged display 10. Therefore, the display unit 10 can be reliably prevented from being damaged, and the main body unit 1 can be safely replaced.

(2) Other Aspects (a) For example, although the first embodiment is applied to a common standby uninterruptible power supply system, it may be applied to a parallel redundant uninterruptible power supply system as shown in FIG. 7. In FIG. 7, reference numeral 13 is a parallel board in which a plurality of main body portions 1 are connected. According to this embodiment, the effect of the first embodiment can be obtained even in a parallel redundant uninterruptible power supply system.

(B) In the first embodiment, the frame side connecting portion 5b electrically connected to the main body portion 1 and the peripheral boards 6 to 8 is provided on the frame body portion 4 side, but the frame side connecting portion 5b is provided. This may be omitted, and the main body side connection portion 5a on the main body portion 1 side may be directly and electrically connected to the peripheral boards 6 to 8 side. According to this embodiment, since it is not necessary to provide the frame side connecting portion 5b, the configuration of the frame body portion 4 can be further simplified.

(C) A jig for fixing the main body 1 may be installed on the main body 1 or the frame body 4. By installing the jig, the stability of the main body 1 is enhanced, so that excellent safety can be obtained.
(D) The main body 1 or the frame 4 may be provided with an auxiliary mechanism for assisting the pulling out or pushing work of the main body 1. Providing an auxiliary mechanism for work has the advantage of improving workability.

(E) The main body 1 or the frame 4 may be provided with an electric shock prevention mechanism for preventing electric shock during replacement work of the main body 1. Regarding the jig, the auxiliary mechanism for replacement work, or the electric shock prevention mechanism, the configuration, shape, material, arrangement location, arrangement number, and the like can be appropriately selected.

(F) A guide member for pulling out or pushing the main body portion 1 from the frame body portion 4, for example, a guide rail portion may be provided. The guide member may be provided on the side surface portion or the bottom surface portion of the main body portion 1, or may be provided on the side surface portion or the bottom surface portion of the frame body portion 4. The configuration, shape, material, arrangement location, arrangement number, and the like of such a guide member can be changed as appropriate.

(G) When the main body 1 is removed from the frame 4, strong stress may be applied to the frame 4 from the input TR boards 6 and the storage battery boards 7 arranged on the left and right. In the first embodiment, since the frame body portion 4 is provided with the back surface portion, the stress can be withstood at the back surface portion, but further, a reinforcing member may be provided on the back surface portion or the like.

According to this embodiment, even if a strong stress is applied to the frame body 4 from the left-right direction after the main body 1 is removed, the frame body 4 may be deformed because the reinforcing portion is provided on the back surface. do not have. Therefore, the new main body portion 1 can be smoothly pushed into the frame body portion 4, and there is no concern that the work efficiency may be lowered.

(H) The shape of the housing of the main body 1 may be generalized regardless of the type. When the uninterruptible power supply system has a plurality of main body units 1, if the replacement timing of the main body unit 1 is deviated, the old main body unit 1 waiting for replacement and the new main body unit 1 that has just been replaced are included in the uninterruptible power supply system. Are mixed. Therefore, by generalizing the shape of the housing of the main body 1, even if the old and new main bodies 1 are mixed in the uninterruptible power supply system, the main body 1 can be smoothly inserted into the frame body 4. be able to.

(I) The arrangement and configuration of the main body side connection portion 5a on the main body portion 1 side may be generalized. As a result, even if the type of the main body portion 1 is different, it is possible to correspond to the frame side connecting portion 5b, and the replacement work of the main body portion 1 can be efficiently performed.

(J) If the arrangement and configuration of the main body side connection portion 5a on the main body portion 1 side are different for each type of the main body portion 1, an adapter may be interposed between the main body portion 1 and the frame body portion 4. In this embodiment, the replacement work of the main body 1 can be easily carried out only by using the adapter.

(Update work of the main body)
In the third embodiment as described above, the work of removing the main body portion 1N from the frame body portion 4N will be described. For example, when the regular machine 10Nb is removed from the frame body portion 4N, the molded case circuit breakers 12Nb to 14Nb are opened and the molded case circuit breaker 15Nb is inserted. As a result, the commercial power supply and the power supply from the spare machine 10Na are stopped for the regular machine 10Nb, so that the main body 1N of the regular machine 10Nb can be removed. Further, the spare machine 10Na will perform UPS power supply to the load to which the regular machine 10Nb has supplied power.

On the other hand, when the regular machine 10Nc is removed from the frame body 4, the molded case circuit breakers 12Nc to 14Nc are opened and the molded case circuit breaker 15Nc is inserted. As a result, the commercial power supply and the power supply from the spare machine 10Na are stopped for the regular machine 10Nc, so that the main body 1N of the regular machine 10Nc can be removed. Further, the spare machine 10Na will perform UPS power supply to the load to which the regular machine 10Nc has been supplying power.

After performing the above operation, the update worker uses the work space 9N to detach the main body side connection portion 5Na on the main body portion 1N side and the frame side connection portion 5Nb on the frame body portion 4N side. .. Therefore, the main body side connection portion 5Na and the frame side connection portion 5Nb are separated from each other and electrically disconnected. After the main body side connection portion 5Na and the frame side connection portion 5Nb are separated from each other, the main body portion 1N is pulled out from the frame body portion 4N to remove the main body portion 1N from the frame body portion 4N.

Next, the work of attaching the new main body portion 1N to the frame body portion 4N will be described.

Is done. At this time, the main body side connection portion 5a is located at the retracted position P1 and does not collide with the frame side connection portion 5Nb on the frame body portion 4N side.

Subsequently, the update worker uses the work space 9N to move the main body side connection portion 5Na from the retracted position P1 to the joining position P2, and the main body side connection portion 5Na and the frame side connection portion on the frame body portion 4N side. Joining work with 5Nb is performed. As a result, the main body side connecting portion 5Na and the frame side connecting portion 5Nb are joined to each other and electrically connected. Since the frame side connection part 5Nb and the external connection part 5Nc are held regardless of the attachment / detachment of the main body part 1N, if the main body side connection part 5Na and the frame side connection part 5Nb are electrically connected, the main body part 1N will be electrically connected to peripheral boards 6N to 8N, which are external devices.

Therefore, for example, when the regular machine 10Nb is attached to the frame body 4, the molded case circuit breakers 12Nb to 14Nb are turned on and the molded case circuit breakers 15Nb are opened and turned on. On the other hand, when the regular machine 10Nc is attached to the frame body portion 4N, the molded case circuit breakers 12Nc to 14Nc are thrown in to open the molded case circuit breaker 15Nc. As a result, the power supply from the commercial power supply and the spare machine 10Na to the regular machine 10Nb and 10Nc is restarted, and the UPS power supply state to the load by the regular machine 10Nb and 10Nc is returned.

Therefore, in the third embodiment, it is possible to prevent damage to the main body side connection portion 5Na and the frame side connection portion 5Nb, and it is possible to exhibit excellent safety during the renewal work.

(C) In the third embodiment, since the main body portion N1 is provided with a work space 9N for joining or disconnecting the main body side connection portion 5Na and the frame side connection portion 5Nb, the update worker can perform the main body. The joining or disconnecting work of the side connecting portion 5Na and the frame side connecting portion 5b can be efficiently performed. Moreover, since the plurality of main body side connection portions 5Na are integrally movable along the attachment / detachment direction of the main body portion 1N, the renewal worker can quickly perform the joining work between the main body side connection portion 5Na and the frame side connection portion 5Nb. It is possible to do. According to such a third embodiment, the efficiency of the update work can be further improved.

(D) In the third embodiment, the main body side connection portion 5Na and the frame side connection portion 5Nb are arranged so as to be detachable even when the main body portion 1N is pushed into the frame body portion 4N. Therefore, the main body side connection portion 5Na functions as a disconnector, and by disconnecting the main body side connection portion 5Na and the frame side connection portion 5Nb during maintenance of the main body portion N1, safe work becomes possible.

At this time, the slight deviation between the electrode plate 311 and the recess 632a is absorbed by the expansion and contraction of the elastic member 324 on the electrode plate 311 side and the movement of the holding body 632 configured as the floating connector. The operator uses the mounting holes 331a to bolt the urging plate 331 to the fixing legs 640 as shown in FIG. 37. As a result, the external cable is connected to the UPS via the main body side connection portion 300 and the frame side connection portion 600.

When disconnecting the main body side connection portion 300 and the frame side connection portion 600, the bolts of the urging plate 331 and the fixing leg 640 are removed, and the handle 332 is held and pulled toward the front side. Then, the plate 311 is disengaged from the recess 632a of the holding body 632, and the electrical connection is released.

By engaging the claws of the holding portion 333 of the pressing portion 330 with the holes provided on the upper surface of the housing 200, the position of the urging plate 331 is set to a disconnecting state in which the electrode plate 331 is separated from the holding body 632.
