Background Art

[0002] An uninterruptible power supply system (UPS) is a system that supplies power of the same standard to a load for a predetermined time even when a power failure occurs. The 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 device, and includes a rectifier that converts alternating current to direct current and an inverter that converts direct current to alternating current. The peripheral panel is an input transformer panel, a battery panel, or the like.

[0003] Generally, the main body and the peripheral panel are 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. In addition, from the viewpoint of aesthetics and the like, the depth dimension and the height dimension of the housing of the main body and the housing of the peripheral panel are unified. The size of these housings is, for example, the depth dimension is slightly less than 100 cm, and the height dimension is about 190 cm.

[0004] A door is attached to the front of the housing of the main body and the like, and the inside of the main body or the inside of the peripheral panel is maintained and inspected by opening this door. Therefore, a working space is provided in front of the main body and the peripheral panel. In addition, the main body and the peripheral panel are updated when their respective expected service lives end. The update of the main body and the peripheral panel means replacing the main body and the peripheral panel with new ones as a whole.

[0005] The expected service life of the main body and the peripheral panel is different, and the implementation time of the replacement work of the main body and the replacement work of the peripheral panel will deviate greatly. Specifically, the expected service life of the main body is about 15 years, and the replacement of the main body is based on 15 years after the installation of the uninterruptible power supply system. On the other hand, the expected service life of the peripheral panel is about 25 years, which is about 10 years later than the replacement time of the main body.

Summary of the Invention

Problems to be Solved by the Invention

[0007] As described above, the replacement work of the main body part must be carried out much earlier than the peripheral panel by 10 years. Therefore, when performing the replacement work of the main body part, although the connection between the main body part and the peripheral panel is removed, the peripheral panel itself remains installed. Therefore, in the replacement work of the main body part, only the main body part to be replaced is removed from the installation location where it was fixed among the housing group arranged in a row, and a new main body part is reinstalled at the same location.

[0008] Since such replacement work of the main body part covers the entire main body part, many construction facilities such as a portal - type construction facility that covers the main body part and a horizontal pulling hook applied to the main body part are indispensable. Therefore, the replacement work of the main body part has become a large - scale operation, and the working time has been prolonged.

[0009] Also, data centers and the like do not have much space. Therefore, the working space provided in front of the main body part is originally narrow. Moreover, considering the entry of construction facilities, the space available for the replacement work of the housing is significantly reduced. Therefore, it is extremely difficult to replace the main body part while it is in the housing state, and the problem is that the working efficiency of the construction is low.

[0010] Furthermore, considering the role of the UPS, the shorter the construction period of the replacement work of the main body part, the better. Therefore, it is necessary to concentrate a large number of workers on the replacement work of the main body part, and the labor cost has soared. As a result, in the replacement work of the main body part, the construction cost including the labor cost has increased, and the renewal cost of the main body part has increased.

[0011] Although there is a desire to suppress the increase in the update cost of the main body, there is also a desire to extend the update timing of the main body as much as possible. However, if the main body is continuously used beyond its expected life, the possibility of defects occurring in the main body increases. If a defect occurs in the main body, the impact may extend to the peripheral boards connected to the main body.

[0012] For this reason, for example, if the main body is continuously used for a long time beyond its 15-year expected life, not only the replacement of the main body but also the replacement of the peripheral boards that have not reached their 25-year expected life may be forced. The replacement work of the peripheral boards is very large-scale, and extending the update timing of the main body may instead increase the economic burden.

[0013] In view of the above situation, it can be said that ensuring the update of the main body by its expected life will lead to a total reduction in the running cost of the entire system. Therefore, there has been a strong demand to reduce the update cost of the main body. In particular, in recent years, with the spread of data centers and the like, the market for renewing the main body is on an expanding trend, and reducing the update cost of the main body has become an urgent task.

[0014] In addition to the issues during the update of the main body as described above, when carrying out installation and removal work such as maintenance of the main body and replacement with an alternative machine, there are also issues such as a considerable construction period and high construction costs. Also, since the work is carried out with the peripheral boards left in place during these construction operations, it is often difficult to secure space.

[0015] In the uninterruptible power supply system, as described above, the difference in the expected life between the main body and the peripheral boards was explained. However, in other power-related boards, there are often differences in the expected life with the peripheral boards, so there are similar issues.

[0016] This embodiment is proposed to solve the above problems, and its purpose is to provide a switchboard for electric power that can easily perform the replacement work of the main body by detaching and attaching the main body to the frame while keeping the main body in the housing, thereby reducing the replacement cost of the main body.

Means for Solving the Problems

[0017] In order to achieve the above object, the switchboard for electric power according to the embodiment of the present invention has the following components (1) and (2). (1) A main body having a housing in which electrical equipment is housed and which is placed in a direction perpendicular to the installation surface (2) A frame portion that surrounds the back surface portion and both side surface portions among the front surface portion, the back surface portion, and both side surface portions of the housing, and the housing is detachably attached by being pushed in and pulled out.

Mode for Carrying Out the Invention

[0019] (1) First Embodiment (Configuration) The power distribution board of the first embodiment will be specifically described with reference to FIGS. 1 to 6. This power distribution board is a board applied to an uninterruptible power supply system (UPS). As shown in the front view of FIG. 1 and the perspective view of FIG. 2, the uninterruptible power supply system is provided with a main body part 1, an input transformer board 6, a battery board 7, and a branch board 8. The input transformer board 6, the battery board 7, and the branch board 8 will also be referred to as peripheral boards 6 to 8.

[0020] The main body part 1 and the peripheral boards 6 to 8 are housed in a substantially rectangular parallelepiped housing and arranged in a row along the wall surface of a data center or the like. Doors are installed on the front of each housing of the main body part 1 and the peripheral boards 6 to 8, and maintenance and inspection of the main body part 1 or the peripheral boards 6 to 7 are performed by opening these doors.

[0021] In FIG. 1, from the left side of the drawing, an input transformer board 6, a main body part 1, a branch board 8, and a battery board 7 are installed in this order. Further, on the main body UPS 1, a display part 10 is provided at a height of 100 cm or more from the bottom surface part. In FIGS. 1 and 2, the main body part 1 is shown lower than the peripheral boards 6 to 8, but this is for clarifying the difference between the main body part 1 and the peripheral boards 6 to 8, and the height dimensions of the main body part 1 and the peripheral boards 6 to 7 may be made the same.

[0022] In the power board according to the first embodiment, a frame body part 4 is provided to support the main body part 1 so as to surround it from the left, right, and below. In FIGS. 1 and 2, the inner part shown by the dotted line is the main body part 1, and the outer part of the dotted line is the frame body part 4. As shown in the side view of FIG. 3, the main body part 1 is arranged in a state of being a housing with respect to the frame body part 4, that is, the entire housing is arranged so as to be pullable out without disassembling the housing. As shown in the perspective view of the main part of FIG. 4, the frame body part 4 has no upper surface part, and includes a bottom surface part, left and right side surface parts, and a back surface part connecting the side surface parts.

[0023] As shown in FIGS. 3 and 4, a main body side connection part 5a is provided at the upper part of the back surface part of the main body part 1, and a frame side connection part 5b is provided at the upper part of the back surface part of the frame body part 4. These connection parts 5a and 5b are arranged to face each other and are electrically connected by being joined. Further, although not shown, the frame side connection part 5b is electrically connected to a predetermined part of the peripheral boards 6 to 8. The main body side connection part 5a and the frame side connection part 5b are configured to be arranged at positions where the connection parts 5a and 5b can be joined by pushing the main body part 1 into the frame body part 4.

[0024] FIG. 5 is a circuit diagram of an uninterruptible power supply system incorporating this embodiment. The uninterruptible power supply system shown in FIG. 5 is a common standby uninterruptible power supply system, and as the main body part 1, one standby unit 1a and a plurality of (three in FIG. 5) normal units 1b are provided. As shown in the circuit diagram of FIG. 6, in the main body part 1, a rectifier 2 for converting alternating current to direct current and an inverter 3 for converting direct current to alternating current are provided.

[0025] (Replacement work of the main body part) In the first embodiment as described above, it is possible to perform the replacement work of the main body 1 by pulling out and pushing in the main body 1 from the frame part 4 while keeping it in the housing state. When removing the main body 1 from the frame part 4, for example, as shown in FIG. 3, first, the upper part of the housing of the main body 1 is gently tilted obliquely forward by the operator's manual operation, that is, to the front side (the left side in FIG. 3) of the main body 1, so as to lift the bottom surface part of the main body 1 from the frame part 4. Subsequently, the operator stands the main body 1 vertically with respect to the floor surface while sliding the lower part of the housing of the main body 1 to the front side (the left side in FIG. 3). Then, while maintaining the vertical state of the main body 1, the operator slides the entire main body 1 to the front side and pulls out the entire main body 1 from the frame part 4.

[0026] When attaching the main body 1 to the frame part 4, for example, as shown in FIG. 4, while keeping the housing of the main body 1 facing directly in front of the frame part 4, for example, two operators push it into the frame part 4. In addition, when performing the replacement work, a member (not shown), such as a roller, for smoothly sliding the main body 1 is installed on the bottom surface part of the main body 1.

[0027] (Operation and Effect) In the present embodiment as described above, there is a main body 1 having a housing that houses a rectifier 2 for converting alternating current to direct current and an inverter 3 for converting direct current to alternating current and is placed in a direction perpendicular to the installation surface, and a frame part 4 that surrounds the back surface part and both side surface parts among the front surface part, the back surface part, and both side surface parts of the housing and is detachable by pushing in and pulling out the housing.

[0028] Therefore, the main body 1 can be easily attached to and detached from the frame part 4 while remaining in the housing state, so that the replacement work of the main body 1 can be easily performed. In addition, since the work can be carried out by pulling out the main body 1 from the frame part 4 even during maintenance of the main body 1, the work efficiency is improved.

[0029] Further, in the present embodiment, a main body side connection portion 5a and a frame side connection portion 5b are provided on the main body portion 1 and the frame portion 4, respectively. These connection portions 5a and 5b are configured such that the joined state of the two is released by pulling out the main body portion 1 from the frame portion 4, and the two are joined by pushing the main body portion 1 into the frame portion 4.

[0030] Therefore, during the replacement work of the main body portion 1, the work of removing and joining the connection portions 5a and 5b can be carried out simultaneously with the attachment and detachment work of the main body portion with respect to the frame portion 4. Moreover, since the main body side connection portion 5a and the frame side connection portion 5b are provided at the upper portions of the main body portion 1 and the frame portion 4, the connection portions 5a and 5b do not become an obstacle during the attachment and detachment of the main body portion. Therefore, the replacement work of the main body portion 1 can exhibit excellent work efficiency.

[0031] Also, during the replacement work of the main body portion 1, construction equipment such as a portal type or a horizontal pulling hook is not required, and a large space for replacing the main body portion 1 can be secured. Therefore, it is possible to replace the main body portion 1 while keeping it in the housing, and the replacement work can be performed quickly and easily. As a result, a significant reduction in the construction cost of the main body portion 1 is realized.

[0032] That is, according to the present embodiment, the economic burden at the time of updating the main body portion 1 is reduced, so that the replacement of the main body portion 1 can be promoted, and it is possible to prevent problems that occur due to use beyond the expected life of the main body portion 1. As a result, the input transformer board 6, the storage battery board 7, and the branch board 8, which are peripheral boards, are not affected by the problems of the main body portion 1 and can fulfill their expected lives. As a result, the total running cost of the uninterruptible power supply system as a whole is reduced, and the economic efficiency is improved.

[0033] Furthermore, in the present embodiment, the display portion 10 is disposed at a height of 100 cm or more from the bottom surface portion of the main body portion 1. Therefore, when the main body portion 1 is pushed into the frame portion 4, the hands of the operator or the like do not hit the display portion 10 that is easily damaged. Therefore, it is possible to surely prevent damage to the display portion 10, and it is possible to safely perform the replacement work of the main body portion 1.

[0034] (2) Other embodiments (a) For example, although the first embodiment is applied to a common standby uninterruptible power supply system, it may also 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 to which a plurality of main body parts 1 are connected. According to this embodiment, even in a parallel redundant uninterruptible power supply system, the effects of the first embodiment can be obtained.

[0035] (b) In the first embodiment, the frame-side connection part 5b electrically connected to the main body part 1 and the peripheral boards 6 to 8 is provided on the frame body part 4 side. However, this frame-side connection part 5b may be omitted, and the main body-side connection part 5a on the main body part 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 connection part 5b, the configuration of the frame body part 4 can be further simplified.

[0036] (c) A jig for fixing the main body part 1 may be installed on the main body part 1 or the frame body part 4. By installing the jig, the stability of the main body part 1 is enhanced, and thus excellent safety can be obtained. (d) An auxiliary mechanism for assisting the pulling-out operation or pushing-in operation of the main body part 1 may be provided on the main body part 1 or the frame body part 4. By providing the auxiliary mechanism for the operation, there is an advantage that the workability is improved.

[0037] (e) An electric shock prevention mechanism for preventing electric shock during the replacement operation of the main body part 1 may be provided on the main body part 1 or the frame body part 4. Regarding the above jig, auxiliary mechanism for the replacement operation, or electric shock prevention mechanism, its configuration, shape, material, arrangement location, number of arrangements, etc. can be appropriately selected.

[0038] (f) A guide member, such as a guide rail part, for pulling out or pushing in the main body part 1 from the frame body part 4 may be provided. The guide member may be provided on the side surface part or bottom surface part of the main body part 1, or may be provided on the side surface part or bottom surface part of the frame body part 4. Regarding the configuration, shape, material, arrangement location, number of arrangements, etc. of such a guide member, it can also be appropriately changed.

[0039] (g) When the main body part 1 is removed from the frame part 4, strong stress may be applied to the frame part 4 from the input TR board 6 and the storage battery board 7 arranged on the left and right. In the first embodiment, since the back surface part is provided on the frame part 4, it can withstand the stress at the back surface part. However, a reinforcing member may be provided on the back surface part or the like.

[0040] According to this embodiment, even if strong stress is applied to the frame part 4 from the left - right direction after the main body part 1 is removed, since the reinforcing part is provided on the back surface part, the frame part 4 will not be deformed. Therefore, a new main body part 1 can be smoothly pushed into the frame part 4, and there is no concern about causing a decrease in work efficiency.

[0041] (h) The shape of the housing of the main body part 1 may be generalized regardless of the type. When the uninterruptible power supply system has a plurality of main body parts 1, if the replacement timing of the main body parts 1 is shifted, there may be a situation where an old main body part 1 waiting for replacement and a newly replaced main body part 1 are mixed in the uninterruptible power supply system. Therefore, by generalizing the shape of the housing of the main body part 1, even if two types of old and new main body parts 1 are mixed in the uninterruptible power supply system, the main body part 1 can be smoothly inserted into the frame part 4.

[0042] (i) The arrangement and configuration of the main - body - side connection part 5a on the main body part 1 side may be generalized. Thereby, even if the types of the main body parts 1 are different, it is possible to correspond to the frame - side connection part 5b, and the replacement work of the main body part 1 can be carried out efficiently.

[0043] (j) When the arrangement and configuration of the main - body - side connection part 5a on the main body part 1 side are different for each type of the main body part 1, an adapter may be interposed between the main body part 1 and the frame part 4. In this embodiment, by simply using the adapter, the replacement work of the main body part 1 can be easily carried out.

[0044] (3) Second Embodiment (Configuration) The switchboard for electric power in the second embodiment will be specifically described with reference to FIGS. 8 to 22. This switchboard for electric power is also a switchboard applied to an uninterruptible power supply system (UPS). The uninterruptible power supply system will be described with reference to the front view of FIG. 8 and the perspective view of FIG. 9. As shown in FIGS. 8 and 9, the uninterruptible power supply system is provided with an input transformer board 6M, a battery board 8M, and a main body portion 9M.

[0045] The input transformer board 6M and the battery board 8M are external devices of the main body portion 9M and are also called peripheral boards. In FIGS. 8 and 9, from the left side of the figure, the input transformer board 6M, the main body portion 9M, and the battery board 8M are installed in this order. That is, the main body portion 9M is arranged with the input transformer board 6 and the battery board 8M sandwiching it from the left and right. The input transformer board 6M, the battery board 8M, and the main body portion 9M are arranged in a row along the wall surface of a data center or the like, and a base portion 7M is installed at the lower part.

[0046] FIG. 10 shows a circuit diagram of the main circuit 11M of the UPS provided in the main body portion 9M. As shown in FIG. 10, the main circuit 11M is provided with a rectifier 12M that converts alternating current to direct current and an inverter 13M that converts direct current to alternating current. Such a main circuit 11M is electrically connected to the input transformer board 6M and the battery board 8M, which are external devices.

[0047] The lead-out structure of the uninterruptible power supply device according to the second embodiment will be described with reference to FIGS. 11 to 22. As shown in FIGS. 11 to 22, a housing 10M is provided in the main body portion 9M. After performing the electrical disconnection between the input transformer board 6M and the battery board 8M and the main circuit 11M, the housing 10M is configured to be removable from the installed position while remaining in the form of the housing 10M, that is, without disassembling the housing 10M at all.

[0048] In this embodiment, while maintaining the form of the housing 10M, the housing 10M is removed from the base portion 7M, and the housing 10M is pulled out from the position where it is installed (the position indicated by the dotted line in FIG. 11), that is, the position sandwiched between the input transformer board 6M and the battery board 8M, to the loading / unloading space S of the main body portion 9M that extends in front of the uninterruptible power supply system. The width dimension of the loading / unloading space S of the main body portion 9M is about 1200 mm.

[0049] As shown in FIGS. 11 to 15, the housing 10M of the main body portion 9M is provided with a front portion 10Ma, a rear portion 10Mb, and a side portion 10Mc. In FIGS. 11 to 15, the right side of the drawing is the front side and the left side is the rear side. A handle 14M is cut out near the center of the side portion 10Mc of the housing 10M. Further, a first mounting hole 1M is provided in the side portion 10Mc of the housing 10M near the front portion 10Ma. The first mounting hole 1M is provided at a position near 200 mm in the direction of the rear portion 10Mb as viewed from the front portion 10Ma (see FIG. 12).

[0050] A second mounting hole 2M is provided in the side portion 10Mc of the housing 10M near the rear portion 10Mb. The second mounting hole 2M is provided at a position near 300 mm in the direction of the front portion 10Ma as viewed from the rear portion 10Mb (see FIG. 12).

[0051] As shown in FIG. 11, third mounting holes 3M are provided near the left and right end portions of the front portion 10Ma of the housing 10M. The third mounting holes 3M are provided at a height near 70 mm from the floor surface in a state where the housing 10M is placed on the base portion 7M. As shown in FIG. 12, the first and second mounting holes 1M and 2M are also provided at a height near 70 mm from the floor surface in a state where the housing 10M is placed on the base portion 7M. The center of gravity of the main body portion 9M is lower than the height in the middle of the main body portion 9M. Therefore, all of the first to third mounting holes 1M to 3M are at a height below the center of gravity of the main body portion 9M.

[0052] Nuts are accommodated in the first to third mounting holes 1M to 3M, and as shown in FIGS. 16 to 18 and FIG. 22, eyebolts 4M are to be attached to the respective mounting holes 1M to 3M. Further, when carrying in and out the main body 9M, a detachable anchor 15M is installed near the floor surface of the carrying-in and out space S. The anchor 15M is arranged perpendicular to the longitudinal direction of the carrying-in and out space S. A lever block (registered trademark) 5M, which is a towing tool, is attached to the anchor 15M. The lever block 5M is provided with a hook portion for hooking the eyebolt 4M.

[0053] As shown in FIGS. 16 to 18 and FIGS. 21 and 22, a rail portion 16M on which the housing 10M can be placed is laid. The rail portion 16M is arranged parallel to the anchor 15M. Note that the reference numeral 17M shown in FIG. 21 is an angle member for receiving the corner portion of the housing 10M.

[0054] (Carrying-out operation of the main body) Next, the carrying-out operation of the main body 9M will be described with reference to FIGS. 12 to 19. As shown in FIG. 16, two rail portions 16M are installed in parallel in front of the front portion 10Ma of the housing 10M. Although not shown, as a premise for performing such an operation, a curing sheet or the like is laid on the floor surface in the carrying-in and out space S.

[0055] Attach an eyebolt 4M to the third mounting hole 3M of the front portion 10Ma of the housing 10. Also, fix the anchor 15M near the floor surface of the carrying-in and out space S, and attach the lever block 5 to the anchor 15. Then, hook the hook portion of the lever block 5 onto the eyebolt 4M attached to the third mounting hole 3M, and operate the lever block 5M to pull out the housing 10M in the right direction in FIG. 8 (the state of shifting from FIG. 12 to FIG. 13).

[0056] As shown in FIG. 17, when the first mounting hole 1M on the side surface portion 10Mc of the housing 10M appears due to the drawer-out of the housing 10M, the drawer-out operation of the housing 10M is temporarily stopped. Then, the hook portion of the lever block 5M is detached from the eyebolt 4M on the side of the third mounting hole 3M, and the eyebolt 4M is attached to the first mounting hole 1M on the side surface portion 10Mc. By hooking the hook portion of the lever block 5M on this eyebolt 4M and operating the lever block 5M, the housing 10 is further pulled out in the right direction in FIG. 16 (the state of shifting from FIG. 13 to FIG. 14).

[0057] As shown in FIG. 18, when the second mounting hole 2M on the side surface portion 10Mc of the housing 10M appears due to the further drawer-out of the housing 10M, the drawer-out operation is temporarily stopped. Then, the hook portion of the lever block 5M is detached from the eyebolt 4M on the side of the first mounting hole 1M, and the eyebolt 4M is attached to the second mounting hole 2M. By hooking the hook portion of the lever block 5 on this eyebolt 4M and operating the lever block 5M, the housing 10M is further pulled out in the right direction in FIG. 17. As a result, the housing 10M is completely lowered from the base portion 7M, and the entire housing 10M is pulled out into the loading / unloading space S (the state of shifting from FIG. 14 to FIG. 15).

[0058] As shown in FIG. 19, the housing 10M pulled out into the loading / unloading space S is lifted by a jack or the like, and the hand lift 18M is inserted thereunder. Finally, using the hand lift 18M, the operator H transports the housing 10M outside through the loading / unloading space S, and the unloading operation of the main body portion 9M is completed.

[0059] (Loading operation of the main body portion) The second embodiment is a drawer-out structure of the uninterruptible power supply device, and it can be used not only for the unloading operation of the main body portion 9M as described above, but also when the main body portion 9M is loaded. Therefore, the loading operation of the main body portion 9M will be described with reference to FIGS. 20 to 22. As shown in FIG. 20, a plurality of operators H use the hand lift 18M to transport the housing 10M of the main body portion 9M through the loading / unloading space S to a position in front of the predetermined installation position.

[0060] As shown in FIG. 21, four corner members 17 are installed in front of the front portion 10Ma of the housing 10M. The housing 10M is lifted by a jack or the like, and the hand lift 18M is pulled out from under the housing 10M and placed on the corner members 17M. The corner receiving dimension of the corner members 17M is, for example, 100 mm from the viewpoint of safety. Two parallel rail portions 16M are arranged between the corner members 17M, and the housing 10M is placed on the rail portions 16M.

[0061] As shown in FIG. 22, an eyebolt 4M is attached to the first mounting hole 1M of the side surface portion 10Mc of the housing 10M. Further, an anchor 15M is fixed near the floor surface of the loading and unloading space S, and a lever block 5M is attached to the anchor 15M. Then, the hook portion of the lever block 5M is hooked on the eyebolt 4M attached to the first mounting hole 1M, and the lever block 5M is operated to push the housing 10M in the left direction of FIG. 21. Then, when the entire housing 10M is placed on the base portion 7M, the loading operation of the main body portion 9M is completed.

[0062] (Function and effect) The second embodiment as described above includes a housing 10M having a front portion 10Ma, a rear portion 10Mb, and a side surface portion 10Mc, and is a drawing-out structure of the main body portion 9M that can be carried out from the installed position while maintaining the form of the housing 10M. A first mounting hole 1M is provided near the front portion 10Ma and a second mounting hole 2M is provided near the rear portion 10Mb on the side surface portion 10Mc, respectively.

[0063] In the above second embodiment, in the first half of the unloading operation of the main body portion 9M, an eyebolt 4M is attached to the first mounting hole 1M located approximately 200 mm from the front portion 10Ma toward the rear portion 10Mb, the lever block 5M is hooked, and the lever block 5M is operated. As a result, the housing 10M is pulled out about halfway to the front side.

[0064] In the latter half of the operation of removing the main body 9M, an eyebolt 4M is attached to the second mounting hole 2M located approximately 300 mm toward the front portion 10Ma as viewed from the back portion 10Mb, and the lever block 5M is re-hung and the lever block 5M is operated. As a result, the entire housing 10M is pulled out into the loading / unloading space S.

[0065] According to the second embodiment, since the housing 10M of the main body 9M is pulled out step by step using two types of mounting holes, i.e., the first and second mounting holes 1M and 2M, the housing 10M is not difficult to pull out halfway, and the entire housing 9M can be surely carried out into the loading / unloading space S. Moreover, the loading / unloading operation of the main body 9M is carried out only by hanging the lever block 5M on the eyebolt 4M attached to the mounting holes 1M to 3M and operating it. Therefore, large-scale construction equipment and the like are not required. As a result, the renewal work of the main body 9M can be efficiently carried out, and a significant reduction in the work cost can be achieved.

[0066] Also, in the second embodiment, since all of the first to third mounting holes 1M to 3M are located at a height of approximately 70 mm from the floor surface, they are provided at a height below the center of gravity of the main body 9M. Therefore, the housing 10M can be stably moved during the loading / unloading of the main body 9M, and the safety during the work is improved. Further, in the second embodiment, since the third mounting hole 3M is provided in the front portion 10Ma of the housing 10M, the housing 10 can be surely pulled out from the initial stage of the operation of removing the main body 9M.

[0067] Moreover, in the second embodiment, since all of the first to third mounting holes 1M to 3M are provided at approximately 70 mm from the floor surface, the eyebolt 4M attached to these mounting holes 1M to 3M is also located at approximately 70 mm from the floor surface. There is an advantage that the lever block 5M can be easily attached to the eyebolt 4M at such a height.

[0068] Also, in the second embodiment, by sliding the housing 10M on the rail portion 16M, it is possible to quickly perform the loading and unloading operations of the main body portion 9M. Furthermore, since the handle 14M is provided on the side surface portion 10Mc of the housing 10M, the loading and unloading operations of the main body portion 9M by the operator H using this handle 14M can also be performed. Therefore, it is possible to handle the loading and unloading operations of the main body portion 9M under all conditions.

[0069] (4) Other aspects For example, the configurations, shapes, and arrangement positions of the first to third mounting holes 1M to 3M can be appropriately changed. Also, in the above embodiment, the lever block 5M was used when loading and unloading the main body portion 9M, but the power for loading and unloading the main body portion 9M and the like can be appropriately selected. Also, a sliding sheet may be attached on the rail portion 16M so that the housing 10M can be easily slid on the rail portion 16M. In this embodiment, it becomes possible to more easily perform the loading and unloading operations of the main body portion 9M.

[0070] Furthermore, similar to the first embodiment and the third and fourth embodiments described later, the housing 10M may be detachably installed with respect to the frame portion surrounding its back surface portion and both side surface portions, and the housing 10M may be pulled out from this frame portion. In this embodiment, even after the housing 10M of the main body portion 9M is pulled out, since the frame portion remains between the input transformer board 6M and the battery board 8M, the frame portion can receive the pressure from the input transformer board 6M and the battery board 8M toward the main body portion 9M side.

[0071] Therefore, when pulling out the housing 10M, no pressure is applied to the housing 10M from the input transformer board 6M and the battery board 8M, and it is possible to smoothly perform the unloading operation of the main body portion 9M. Also, there is no worry that the input transformer board 6M and the battery board 8M will fall into the space after the housing 10M is pulled out even slightly and the space will become narrow. For this reason, it is possible to surely perform the loading operation of the main body portion 9M.

[0072] (5) Third embodiment (Configuration) The switchboard for electric power in the third embodiment will be specifically described with reference to FIGS. 23 to 30. This switchboard for electric power is also a switchboard applied to an uninterruptible power supply system (UPS). As shown in the front view of FIG. 23 and the perspective view of FIG. 24, the uninterruptible power supply system is provided with a main body 1N, an input transformer board 6N, a battery board 7N, and a branch board 8N. The input transformer board 6N, the battery board 7N, and the branch board 8N are peripheral boards 6N to 8N around the main body 1N and are external devices of the main body 1N.

[0073] The main body 1N which is the main body part and the peripheral boards 6N to 8N are housed in a substantially rectangular parallelepiped housing and are arranged in a row along the wall surface of a data center or the like. Doors are installed on the front of each housing of the main body 1N and the peripheral boards 6N to 8N, and maintenance and inspection of the main body 1N or the peripheral boards 6N to 8N are performed by opening these doors.

[0074] In FIG. 23, from the left side of the drawing, the input transformer board 6N, the main body 1N, the branch board 8N, and the battery board 7N are installed in this order. In FIGS. 23 and 24, the main body 1N is shown lower than the peripheral boards 6N to 8N, but this is for clearly showing the difference between the main body 1 and the peripheral boards 6N to 8N, and the height dimensions of the main body 1N and the peripheral boards 6N to 8N may be made the same.

[0075] FIG. 25 is a circuit diagram of the uninterruptible power supply system incorporating this embodiment. The uninterruptible power supply system shown in FIG. 25 is a common standby UPS system, and as the main body 1N, one standby unit 10Na and a plurality of (two in FIG. 25) normal units 10Nb, 10Nc are provided. That is, the third embodiment is applied to a common standby UPS system. The main body 1N is provided with a rectifier 2N that converts alternating current to direct current and an inverter 3N that converts direct current to alternating current. In FIG. 25, the portion surrounded by the thick two-dot chain line is the main body 1N, and the portion surrounded by the one-dot chain line is the frame portion 4N.

[0076] As shown in FIGS. 26 to 30, the main body 1 is a rectangular parallelepiped housing having a front surface portion, a rear surface portion, an upper surface portion, a bottom surface portion, and left and right side surface portions. The main body 1N is detachably installed on the frame portion 4N. The frame portion 4N has no front surface portion and upper surface portion, and has a bottom surface portion, left and right side surface portions, and a rear surface portion connecting the side surface portions, and supports the main body 1 from the left and right and downward. When the main body 1 is attached to the frame portion 4N, the rear surface portion of the main body 1N and the rear surface portion of the frame portion 4N are in contact with each other. These contacting rear surface portions are defined as the contact surfaces 11N and 41N of the main body 1N and the frame portion 4N, respectively.

[0077] As shown in FIGS. 26 to 30, on the main body 1N, a main body side connection portion 5Na is provided above the contact surface 11N. The main body side connection portion 5Na is an internal connection portion electrically connected to the rectifier 2 or the inverter 3, and is a movable connection portion movable along the attachment / detachment direction of the main body 1N with respect to the frame portion 4N.

[0078] Further, on the frame portion 4N, two connection portions, namely, a frame side connection portion 5Nb and an external connection portion 5Nc, are provided. The frame side connection portion 5Nb is fixedly provided above the contact surface 41N of the frame portion 4N and is for electrically connecting to the main body side connection portion 5Na. The external connection portion 5Nc is an external wire terminal to which an external wire cable connecting to the peripheral boards 6N to 8N is connected and is housed inside the frame portion 4N. Regarding the positional relationship between the frame side connection portion 5Nb and the external connection portion 5Nc, in the present embodiment, the external connection portion 5Nc was installed below the frame side connection portion 5Nb, but it may be installed above. When the external wire cable connecting to the peripheral boards 6N to 8N extends from above the frame portion 4N, the external connection portion 5Nc is installed above the frame side connection portion 5Nb, and when the external wire cable extends from below, the external connection portion 5Nc is installed below the frame side connection portion 5Nb, so that the connection at each connection portion becomes simple.

[0079] (Main body side connection portion and frame side connection portion) The main body side connection part 5Na and the frame side connection part 5Nb are arranged to face each other. When the main body side connection part 5Na is not joined to the frame side connection part 5Nb, it is arranged at a retracted position P1 that is sufficiently separated from the frame side connection part 5Nb so as not to contact the frame side connection part 5Nb on the frame body part 4N side. The retracted position P1 is provided near the front of the main body part 1N.

[0080] Also, let the position where the main body side connection part 5Na and the frame side connection part 5Nb are joined be the joining position P2. In FIG. 30, a state where the main body side connection part 5Na has moved to the joining position P2 is shown. The main body side connection part 5Na is configured to move linearly between the retracted position P1 and the joining position P2. When the main body side connection part 5Na detaches from the frame side connection part 5Nb, the two are electrically disconnected.

[0081] By the way, in the circuit diagram of FIG. 25, the connection part composed of the main body side connection part 5Na and the frame side connection part 5Nb is shown as the first connection part A (indicated by a black circle), and the connection part composed of the frame side connection part 5Nb and the external connection part 5Nc is shown as the second connection part B (indicated by a white circle). Four of the first connection parts A are provided on the contact surfaces 11N and 41N between the main body part 1N and the frame body part 4N, and four of the second connection parts B are provided inside the frame body part 4N.

[0082] Two of the four connection parts A and B are provided on the input side of the main body part 1N, one on the output side of the main body part 1N, and one on the side of the battery tray 7N. The fact that there are four of the first connection parts A means that there are also four main body side connection parts 5Na. Although the four main body side connection parts 5Na are at different positions in the circuit diagram, they are attached to the same member and are integrally movable.

[0083] Also, in Fig. 25, reference numerals 12Nb and 13Nb indicate the upper-side wiring circuit breakers in the normal machine 10Nb, and reference numerals 14Nb and 15Nb indicate the lower-side wiring circuit breakers in the normal machine 10Nb. Further, reference numerals 12Nc and 13Nc indicate the upper-side wiring circuit breakers in the normal machine 10Nc, and reference numerals 14Nc and 15Nc indicate the lower-side wiring circuit breakers in the normal machine 10Nc. The wiring circuit breakers 12Nb to 14Nb and 12Nc to 14Nc are connected to the second connection part B, that is, the frame-side connection part 5Nb and the external connection part 5Nc. Also, the wiring circuit breakers 15Nb and 15Nc are connected to the standby machine 10Na side.

[0084] Furthermore, as shown in Figs. 26 to 30, a working space 9N is provided closer to the front of the main body part 1N as viewed from the retracted position P1 of the main body-side connection part 5Na. The working space 9N is for performing the joining or detachment work between the main body-side connection part 5Na and the frame-side connection part 5Nb.

[0085] (Update work of the main body part) In the third embodiment as described above, the work of removing the main body part 1N from the frame body part 4N will be described. For example, when removing the normal machine 10Nb from the frame body part 4N, the wiring circuit breakers 12Nb to 14Nb are opened and the wiring circuit breaker 15Nb is turned on. As a result, the power supply from the commercial power supply and the standby machine 10Na to the normal machine 10Nb stops, so the main body part 1N of the normal machine 10Nb becomes in a removable state. Also, the standby machine 10Na will perform UPS power supply to the load that the normal machine 10Nb was supplying power to.

[0086] On the other hand, when removing the normal machine 10Nc from the frame body part 4, the wiring circuit breakers 12Nc to 14Nc are opened and the wiring circuit breaker 15Nc is turned on. As a result, the power supply from the commercial power supply and the standby machine 10Na to the normal machine 10Nc stops, so the main body part 1N of the normal machine 10Nc becomes in a removable state. Also, the standby machine 10Na will perform UPS power supply to the load that the normal machine 10Nc was supplying power to.

[0087] After performing the above operations, the update operator uses the working space 9N to disconnect the main body side connection part 5Na on the main body part 1N side from the frame side connection part 5Nb on the frame part 4N side. For this purpose, the main body side connection part 5Na and the frame side connection part 5Nb are separated from each other and electrically disconnected. After the main body side connection part 5Na and the frame side connection part 5Nb are disconnected, the main body part 1N is removed from the frame part 4N by pulling out the main body part 1N from the frame part 4N.

[0088] Next, the operation of attaching a new main body part 1N to the frame part 4N will be described. Push the new main body part 1N against the frame part 4N. When the contact surface 11N on the back surface of the main body part 1N and the contact surface 41N on the back surface of the frame part 4N come into contact with each other, the positioning of both is achieved. At this time, the main body side connection part 5a is located at the retracted position P1 and does not collide with the frame side connection part 5Nb on the frame part 4N side.

[0089] Subsequently, the update operator uses the working space 9N to move the main body side connection part 5Na from the retracted position P1 to the joining position P2 and perform the joining operation between the main body side connection part 5Na and the frame side connection part 5Nb on the frame part 4N side. As a result, the main body side connection part 5Na and the frame side connection part 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 and detachment of the main body part 1N, when 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 the peripheral boards 6N to 8N which are external devices.

[0090] Therefore, for example, when attaching the normal machine 10Nb to the frame part 4, turn on the wiring circuit breakers 12Nb to 14Nb and open and turn on the wiring circuit breaker 15Nb. On the other hand, when attaching the normal machine 10Nc to the frame part 4N, turn on the wiring circuit breakers 12Nc to 14Nc and open the wiring circuit breaker 15Nc. As a result, the power supply from the commercial power supply and the standby machine 10Na to the normal machines 10Nb and 10Nc is resumed, and the UPS power supply state to the load by the normal machines 10Nb and 10Nc is restored.

[0091] (Function and effect) In the third embodiment, a main body unit 1N that houses a rectifier 2N for converting alternating current to direct current and an inverter 3N for converting direct current to alternating current inside a housing, and a frame unit 4N that detachably installs the main body unit 1N are provided. On the main body unit 1N side, a movable contact portion 5Na is provided, and on the frame unit 4N side, a frame-side connection portion 5Nb that can be electrically connected and disconnected from the main body-side connection portion 5Na and an external connection portion 5Nc that is electrically connected to an external device are provided.

[0092] (a) According to such a third embodiment, when the main body unit 1N is removed from the frame unit 4N, the frame-side connection portion 5Nb and the external connection portion 5Nc installed on the frame unit 4N side can maintain the joined state. Therefore, it is not necessary to disconnect the electrical connection between the peripheral boards 6N to 8N, which are external devices, and the frame unit 4N, and the update work can be easily carried out.

[0093] External cables or the like that electrically connect the main body unit 1N side and the peripheral boards 6N to 8N are deformed by heat or the like after the start of operation. Once they are disconnected, it is almost impossible to reconnect them. Therefore, in the prior art in which the electrical connection portion with the peripheral boards 6N to 8N, which are external devices, is disconnected during the update work of the main body unit 1N, it is also indispensable to replace the external cable, and the update cost increases.

[0094] On the other hand, in the third embodiment, the electrical connection between the peripheral boards 6N to 8N and the frame unit 4N is not disconnected. Therefore, even after the update of the main body unit 1N, the existing external cable, which is the external connection portion 5Nc, can be reused and replacement is unnecessary. As a result, the update cost can be significantly reduced, which is economically advantageous.

[0095] (b) Usually, the weight of the main body unit 1N is quite heavy. If the main body-side connection portion 5Na and the frame-side connection portion 5Nb collide when the main body unit 1N is strongly pushed into the frame unit 4N, the connection portions 5Na and 5Nb may be damaged. Therefore, in the third embodiment, if the main body unit 1N is detached from the frame unit 4N, the main body-side connection portion 5a is positioned at the retracted position P1.

[0096] Therefore, even if the main body 1N is strongly pushed into the frame 4N during the operation of attaching the main body 1N to the frame 4N, first, the contact surfaces 11N and 41N of the main body 1N and the frame 4N come into contact with each other, and the main body side connection part 5Na and the frame side connection part 5Nb do not directly collide. Therefore, in the third embodiment, it is possible to prevent damage to the main body side connection part 5Na and the frame side connection part 5Nb, and it is possible to exhibit excellent safety during the renewal work.

[0097] (c) In the third embodiment, since the working space 9N for performing the joining or detaching operation of the main body side connection part 5Na and the frame side connection part 5Nb is provided in the main body part N1, the renewal worker can efficiently perform the joining or detaching operation of the main body side connection part 5Na and the frame side connection part 5b. Moreover, since the plurality of main body side connection parts 5Na move integrally along the attachment / detachment direction of the main body part 1N, the renewal worker can quickly perform the connection operation of the main body side connection part 5Na and the frame side connection part 5Nb. According to such a third embodiment, the efficiency of the renewal work can be further improved.

[0098] (d) In the third embodiment, the main body side connection part 5Na and the frame side connection part 5Nb are arranged so that they can be connected and disconnected even when the main body part 1N is pushed into the frame part 4N. Therefore, the main body side connection part 5Na functions as a circuit breaker, and by disconnecting the connection between the main body side connection part 5Na and the frame side connection part 5Nb during the maintenance of the main body part N1, a safe operation becomes possible. (e) In the third embodiment, the above effects can be obtained in the common standby UPS system.

[0099] (6) Other aspects For example, although the above third embodiment is applied to the common standby UPS system, it may be applied to a parallel redundant uninterruptible power supply system as shown in Fig. 31. In Fig. 31, reference numeral 16 is a parallel board to which a plurality of main body parts 1N are connected, reference numeral 17 is an upper side wiring circuit breaker, and reference numeral 18 is a lower side wiring circuit breaker.

[0100] In this embodiment, after opening the wiring circuit breakers 17N and 18N connected to the main body 1N to be removed, the main body 1N is removed from the frame body 4. Also, when attaching the main body 1N to the frame body 4N, the wiring circuit breakers 17N and 18N are turned on after attaching the main body 1N to the frame body 4N. According to the above embodiment, in the parallel redundant uninterruptible power supply system, the effects of the above-described third embodiment can be obtained.

[0101] A guide member, such as a guide rail part, for pulling out or pushing in the main body 1N from the frame body 4N may be provided. The guide member may be provided on the side surface or bottom surface of the main body 1N, or may be provided on the side surface or bottom surface of the frame body 4N. Regarding the configuration, shape, material, arrangement location, and number of such guide members, etc., they can be appropriately changed.

[0102] In the above-described third embodiment, the internal connection part on the main body 1N side is the main body side connection part 5Na which is a movable connection part, but the frame side connection part 5Nb on the frame body 4N side may also be a movable connection part. The movable directions of these movable connection parts are not limited to the attachment / detachment direction of the main body 1N with respect to the frame body 4N. For example, one connection part may be arranged facing upward, and the other connection part may move so as to cover it from above and connect to it.

[0103] (7) Fourth Embodiment The power distribution board of the fourth embodiment will be specifically described with reference to FIGS. 32 to 42. This power distribution board is also a board applied to an uninterruptible power supply system (UPS). As shown in FIG. 32, the fourth embodiment has a main body 100, a frame body 400, and a base part 800 (see FIG. 42). Similar to the above-described embodiment, as shown in FIG. 33, the housing 200 of the main body 100 is attached and detached by being pushed into and pulled out from the frame body 400.

[0104] [Main Body] The configuration of the main body 100 will be described. The main body 100 has a housing 200 and a main body side connection part 300.

[0105] [Housing] As shown in Fig. 34, the housing 200 is a substantially rectangular parallelepiped-shaped container in which electrical equipment constituting an uninterruptible power supply (UPS) is housed and is placed in a direction perpendicular to the installation surface. Hereinafter, the front face of the housing 200 is referred to as the front part 201, the rear face as the back part 202, the left and right faces as viewed from the front as the side parts 203 and 204, respectively. Further, the upper face is referred to as the upper part 205, and the lower face as the bottom part 206. Also, the horizontal lateral direction of the housing 200 is referred to as the width direction, and the front-rear direction as the depth direction.

[0106] The front part 201 of the housing 200 is open, and as shown in Fig. 35, a door 210 for opening and closing it is provided. As shown in Fig. 36, a plurality of lead-out terminals 220 are provided on the back part 202 of the housing 200. A cable drawn from the electrical equipment is connected to the inner side of the housing 200 of each lead-out terminal 220. The plurality of lead-out terminals 220 are arranged side by side in the width direction at the upper part of the back. These lead-out terminals 220 are divided into a plurality of types of input / output classifications as will be described later (see Fig. 35).

[0107] As shown in Fig. 34, the first to third mounting holes 1M to 3M are provided at the same positions on the front part 201 and the side parts 202 of the housing 200 as in the above-described second embodiment. As described above, the first to third mounting holes 1M to 3M are provided so that the eyebolt 4 can be attached.

[0108] [Main body side connection part] The main body side connection part 300 is a component that makes an electrical connection with an external wire connection part 600 to be described later. As shown in Figs. 34 to 37, the main body side connection part 300 includes an electrode part 310, a support part 320, and a pressing part 330.

[0109] (Electrode part) As shown in Fig. 36, the electrode part 310 includes an electrode plate 311 and a flexible conductor 312.

[0110] The electrode plate 311 is a conductive plate and is arranged parallel to the side surface of the housing 200. The electrode plate 311 constitutes a fitting portion with a connector portion 630 described later. The lower part of the electrode plate 311 is a vertical support surface 311a extending downward from the upper part of the housing 200 to the back side. The upper part of the electrode plate 311 is a vertical contact-separation surface 311b protruding from the upper part of the housing 200. Since the support surface 311a and the contact-separation surface 311b form a continuous plate surface via a relay surface 311c in the front-rear direction, the electrode plate 311 has a crank shape as a whole.

[0111] The flexible conductor 312 is a member in which a flexible member 312c, which is a flexible conductor, connects between a pair of conductive terminals 312a and 312b. One terminal 312a of the flexible conductor 312 is connected to the lead-out terminal 220 on the back surface portion 202 of the housing 200. The other terminal 312b of the flexible conductor 312 is connected to the support surface 311a of the electrode plate 311.

[0112] (Support portion) The support portion 320 is a component that supports the electrode plate 311 while allowing movement in the depth direction and the width direction with respect to the housing 200. As shown in FIG. 36, the support portion 320 includes a guide rail 321, a slider 322, a movable portion 323, and an elastic member 324.

[0113] The guide rail 321 is an elongated member with a substantially U-shaped cross-section where the back side of the housing 200 is open. The guide rail 321 is attached in the width direction of the housing 200. The slider 322 is an elongated member with a square tube shape inserted into the guide rail 321 and slides in the width direction of the housing 200 along the guide rail 321.

[0114] The movable part 323 has a moving plate 323a and a support plate 323b. The moving plate 323a is attached to the slider 322 and is a flat plate that slides in parallel with the back surface of the housing 200. The support plate 323b is a member with an L-shaped cross section, and the portion parallel to the back surface portion 202 is attached to the moving plate 323a. A pair of guide holes 323c extending in the depth direction are formed vertically in the portions parallel to the side surface portions 203 and 204 of the support plate 323b.

[0115] The elastic member 324 is a compression coil spring that expands and contracts in the width direction. Two elastic members 324 are provided vertically in the width direction of the housing 200. One end of each elastic member 324 is inserted into the guide hole 323c of the support plate 323b and is configured to be slidable in the depth direction. The other end of each elastic member 324 is fixed to the support surface 311a of the electrode plate 311.

[0116] With the above configuration of the support portion 320, the electrode plate 311 can move in the width direction of the housing 200 together with the slider 322 that moves along the guide rail 321. Also, it can move in the depth direction of the housing 200 together with the elastic member 324 that moves along the guide hole 323c. The electrode plate 311 is biased toward the back side, and the contact / separation surface 311b fits into the clamping body 632 described later. Even if the position of the electrode plate 311 is displaced with respect to the lead-out terminal 220, conduction is ensured by the deformation of the flexible conductor 312.

[0117] As shown in FIG. 35, a plurality of electrode plates 311 are prepared for each section. For example, 4 are provided in the DC input section E1, 3 in the AC input section E2, 3 in the bypass input section E3, and 4 in the AC output section E4. For DC input, it corresponds to 2 positive electrodes and 2 negative electrodes. For AC input and bypass input, it corresponds to 3 phases. For AC output, it corresponds to 3 phases and the ground wire.

[0118] (Pressing portion) As shown in FIGS. 36 and 37, the pressing portion 330 is a member that biases the electrode plate 311 of the electrode portion 310 toward the back side and pushes it into a frame-side connection portion 600, which will be described later. The pressing portion 330 includes a biasing plate 331, a handle 332, and a holding portion 333. The biasing plate 331 is a plate that covers a part of the connector portion 630. The biasing plate 331 is parallel to the back surface of the housing 200 and has a rectangular shape that is long in the width direction. The biasing plate 331 is formed of a transparent material so that the insertion state of the electrode plate 311 can be visually recognized. Note that a punched steel plate may be used for the electrode plate 311.

[0119] Furthermore, as shown in FIG. 36, a plurality of elastic members 331a are attached to the biasing plate 331 so as to be interposed between the biasing plate 331 and the electrode plate 311. The elastic member 331a is a compression coil spring that expands and contracts in the depth direction. One end of the elastic member 331a is attached to the front edge portion of each electrode plate 311 via a plate or the like, and the other end is attached to the back surface of the biasing plate 331. Two elastic members 331a are provided corresponding to each electrode plate 311, and these two elastic members 331a are arranged side by side vertically.

[0120] As shown in FIG. 37, the handle 332 is a substantially U-shaped bar member. Both ends of the handle 332 are fixed to the front surface of the biasing plate 331 such that the longitudinal direction thereof is the width direction of the housing 200. In addition, mounting holes 331a for fastening to fixing legs 640 of the frame-side connection portion 600, which will be described later, with bolts are formed in the vicinity of both ends of the biasing plate 331.

[0121] As shown in FIG. 37, the holding portion 333 is a member that holds the pressing portion 330 at a distance where the electrode plate 331 is electrically insulated from the connector portion 630. The holding portion 333 is a latch having claws fixed to the front surface side of the biasing plate 331. The holding portion 333 holds the position of the biasing plate 331 at a position where the electrode plate 331 is separated from the sandwiching body 632 by engaging the claws with holes (not shown) provided in the upper surface portion 205 of the housing 200.

[0122] The pressing part 330 as described above is provided for each of the above-described input / output sections E1 to E4. That is, as shown in FIG. 35, four biasing plates 331 are configured to bias a plurality of electrode plates 331 together for each of the respective sections E1 to E4.

[0123] [Frame body part] As shown in FIGS. 32 and 33, the frame body part 400 is a member in which the housing 200 is accommodated inside. The frame body part 400 has an enclosing part 500, a frame-side connection part 600, and a guide part 700.

[0124] (Enclosing part) The enclosing part 500 is a member that encloses both side surfaces and the back surface of the housing 200 in a U-shape. The enclosing part 500 has a vertical body 510 and side bodies 520.

[0125] The vertical body 510 is a thin housing that stands upright on the installation surface. The height of the vertical body 510 is formed 20 to 25% higher than that of the housing 200. The front of this higher part becomes a protruding part 511 that protrudes upward when the housing 200 is accommodated. The vertical body 510 is provided so as to be separable vertically with a straight line in the width direction as a boundary.

[0126] The side bodies 520 are members that cover the side surfaces of the accommodated housing 200 by extending from both side edges of the vertical body 510 at a right angle to the front side. The side bodies 520 are configured by stacking two U-shaped frames 521 and 522 having a rectangular shape vertically. The central parts of the upper and lower horizontal parts of the frames 521 and 522 are connected by vertical columns 521a and 522a. The side bodies 520 are provided so as to be separable vertically at a height that coincides with the boundary between the frames 521 and 522 and the boundary of the vertical body 510.

[0127] The side bodies 520 have side plates 523 and 524 attached so as to cover the outer surfaces of the frames 521 and 522. Further, the side bodies 529 have a front panel 525 that continuously covers the front surfaces of the frames 521 and 522 and fills the gap with an adjacent board.

[0128] Note that, as described above, since the surrounding portion 500 is divided at the boundary between the vertical surface body 510 and the side surface body 520, as shown in Fig. 39, it is provided so as to be dividable into an upper surrounding portion 500A and a lower surrounding portion 500B. Bolt holes 521b and 522b into which a suspension bolt R can be fastened are formed on the upper surface of the frame 521 of the upper surrounding portion 500A and the upper surface of the frame 522 of the lower surrounding portion 500B.

[0129] (Frame side connection part) The frame side connection part 600 is a component configured to make an electrical connection with an outside line cable via the main body side connection part 300. As shown in Figs. 38 and 39, the frame side connection part 600 is arranged side by side in the width direction on the front surface of the protruding part 511. The frame side connection part 600 has a fixing plate 610, an outside line terminal 620, a connector part 630, and a fixing leg 640 (see Fig. 38). Note that, as shown in Fig. 32, by providing a cover CB on the frame body part 400 so that the connection part between the frame side connection part 600 and the main body side connection part 300 is not exposed, it is possible to ensure safety so that an operator does not touch the connection part during energization. This cover CB can increase the insulation distance more by using an insulating material such as resin, but it may also be a metal material.

[0130] In addition, after the operation starts, there may be a case where the connection part is imaged with a thermal camera to check whether an abnormal temperature has been reached. Therefore, by providing a hinge or the like at the connection part between the frame body part 400 and the cover CB, this cover CB can be easily opened and closed during inspection, so that the work efficiency is improved. In addition, by providing a hole in the cover CB so that the connection part can be seen from the front of the main body part 100, inspection using a thermal camera is also facilitated.

[0131] The fixing plate 610 is a conductive rectangular plate. The fixing plate 610 is supported and fixed to the front surface of the protruding part 511 via a plurality of elastic members 611 so that the long side direction is perpendicular. The elastic member 611 is a compression coil spring that expands and contracts in the depth direction.

[0132] The external line terminal 620 is a conductive plate, which is a plate with an L-shaped cross-section consisting of two orthogonal surfaces. One surface of the external line terminal 620 is fixed to the upper part of the fixing plate 610. The other surface of the external line terminal 620 protrudes forward, and a hole 621 for connection with the terminal of the external cable is formed.

[0133] The connector part 630 is a member into which the electrode plate 311 is inserted and removed. That is, the electrode plate 311 and the connector part 630 move from the main body side connection part 300 toward the frame side connection part 600 and fit together with each other to constitute a fitting part that is electrically connected. The connector part 630 includes a mounting plate 631, a clamping body 632, and a contact electrode 633. The mounting plate 631 is a conductive plate and is attached to the lower part of the external line terminal 610 with respect to the fixing plate 610. The clamping body 632 has a recess 632a into which the electrode plate 311 is inserted. The recess 632a is formed in the height direction of the housing 200 and clamps the inserted electrode plate 311 in the width direction.

[0134] Also, the clamping body 632 is movably attached to the mounting plate 631 in the height direction and the width direction of the housing 200, and is biased to a fixed position by an elastic member (not shown). This guiding width can be, for example, several millimeters in the height direction and the width direction. Thereby, the clamping body 632 constitutes a floating connector that can absorb the positional deviation between the electrode plate 311 and the recess 632a by the recess 611 following the position of the electrode plate 311 when the electrode plate 311 is inserted.

[0135] The contact electrode 633 is a conductor that contacts the electrode plate 311 inserted into the recess 611 and is electrically connected. The contact electrode 633 is electrically connected to the external line terminal 620 via the mounting plate 631 and the fixing plate 610.

[0136] Such clamping bodies 632 of the connector part 630 are arranged in plurality with respect to one electrode plate 311. In the present embodiment, three clamping bodies 632 are provided. The contact electrodes 633 of these clamping bodies 632 equally share the rated current. For example, when the rated current is 300 A, a current of about 100 A can flow. However, a single clamping body 632 that bears the rated current may also be used.

[0137] As shown in FIGS. 38 and 39, the fixing leg 640 is a plate that is fixed to the vertical body 510 and holds the electrode plate 311 in a position that prevents the electrode plate 311 from coming off by attaching the biasing plate 331 that presses the electrode plate 311.

[0138] The fixing leg 640 has its rear end attached to the front of the protruding portion 511 of the vertical body 510 and extends forward. The front end of the fixing leg 640 is bent in a direction parallel to the back surface, and a mounting hole 641 for attaching the biasing plate 331 is formed.

[0139] The number of arrangements of the frame-side connection part 600 as described above corresponds to the number of lead terminals 220 divided into a plurality of types of input / output classifications. For example, four are provided for the DC input classification E1, three for the AC input classification E2, three for the bypass input classification E3, and four for the AC output classification E4.

[0140] (Guide part) The guide part 700 is a component that guides the movement of the main body part 100 inserted and removed into the frame body part 400. As shown in FIG. 41, the guide part 700 has guide rollers 710. The guide rollers 710 have shafts 711 and rollers 712. The shaft member 711 is a rod-shaped member erected in the height direction at the lower part of the side body 520. The roller 712 is a cylindrical resin member with the shaft member 711 fixed to the central axis. A plurality of guide rollers 710 are arranged in the depth direction inside both side bodies 520. The side surfaces of the rollers 710 protrude inward and come into contact with and separate from the side surface parts 203 and 204 of the main body part 100 to be inserted and removed.

[0141] [Base part] The base part 800 is a member that intervenes between the main body part 100 and the installation surface and supports the main body part 100. As shown in FIG. 42, the base part 800 is a rectangular frame-shaped plate, and with the short side direction as the depth direction, it is inserted into the bottom of the frame body part 400. A plurality of strip-shaped bridging plates 810 are arranged in the short side direction on the base part 800.

[0142] Smooth sheets 820 are attached to the bottom surfaces of both short sides of the base part 800 and the bottom surfaces of the bridging plates 810. As the sheet 820, for example, a ultra-high molecular weight polyethylene tape is used. The base part 800 is placed such that the surface with the sheet 820 attached contacts the installation surface, and the housing 200 of the main body part 100 is placed on the opposite surface. Note that a sheet with the same smoothness as the sheet 820 is also attached to the bottom surface of the housing 200.

[0143] (Installation work) The work of installing the frame body part 400 and the main body part 100 as described above will be explained. First, the frame body part 400 is installed between adjacent boards as shown in the above-described embodiment. When carrying the frame body part 400 in and out, as shown in FIG. 39, it can be transported after being divided into the upper surrounding part 500A and the lower surrounding part 500B. At this time, a suspension bolt R can be fastened to the bolt holes 521b and 522b of the upper surrounding part 500A and the lower surrounding part 500B respectively and lifted. Thereby, it becomes possible to move even in a place with a height limit such as an elevator.

[0144] The work of attaching and detaching the main body part 100 to and from the frame body part 400 is the same as that in the second embodiment. That is, the housing 200 can be taken in and out of the frame body part 400 using the base part 800 and the eyebolt 4M attached to the first to third mounting holes 1M to 3M. When taking the housing 200 placed on the base part 800 in and out, the base part 800 slides on the installation surface due to the sheet 820 provided on the base part 800, so the taking in and out becomes smooth. Also, since the rollers 712 of the guide rollers 710 rotate in contact with the lower parts of the side surfaces 203 and 204 of the housing 200, the taking in and out of the housing 200 becomes smooth.

[0145] After attaching the main body part 100 to the frame part 400, connect the outside line cable to the frame side connection part 600. Insert a bolt through the hole of the terminal provided at the tip of the outside line cable and the hole 611 of the outside line terminal 620, and tighten and fix with a nut.

[0146] (Electrical connection work) The operation of connecting the main body side connection part 300 to the frame side connection part 600 will be described. As shown in FIG. 33, when the main body part 100 is attached to the frame part 400, the electrode plate 311 of the electrode part 310 and the clamping body 632 of the connector part 630 face each other.

[0147] The operator holds the handle 332 of the biasing plate 331 of the pressing part 330 and moves it in the width direction to adjust the position in the width direction between the electrode plate 311 and the clamping body 632, and then, as shown in FIG. 37, pushes the biasing plate 331 toward the back side. The pressure during pushing is alleviated by the elastic members 331a and 611. Then, as shown in FIG. 41, the contact and separation surface 311b of the electrode plate 311 fits into the recess 632a of the clamping body 632 and contacts the contact electrode 633, thereby being electrically connected.

[0148] At this time, a 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 clamping body 632 configured as a floating connector. The operator uses the mounting hole 331a to fix the biasing plate 331 to the fixing leg 640 with bolts as shown in FIG. 37. Thereby, the outside line cable is connected to the UPS via the main body side connection part 300 and the frame side connection part 600.

[0149] When disconnecting the connection between the main body side connection part 300 and the frame side connection part 600, remove the bolt fixing between the biasing plate 331 and the fixing leg 640, hold the handle 332, and pull it toward the front side. Then, the plate 311 comes out of the recess 632a of the clamping body 632, and the electrical connection is released.

[0150] By engaging the claws of the holding portion 333 of the pressing portion 330 with the holes provided in the upper surface of the housing 200, the position of the biasing plate 331 can be held in an open circuit state where the electrode plate 331 is separated from the clamping body 632.

[0151] (Function and effect) (1) In this embodiment, the main body side connection portion 300 and the frame side connection portion 600 have a fitting portion that is electrically connected by the main body side connection portion 300 moving toward the frame side connection portion 600 and fitting with each other.

[0152] Therefore, when removing the main body portion 100, by removing the main body side connection portion 300 in the fitting portion from the frame side connection portion 600, the work of disconnecting the external cable becomes unnecessary. Also, when attaching the main body portion 100, by fitting the main body side connection portion 300 in the fitting portion to the frame side connection portion 600, the work of wiring the external cable becomes unnecessary.

[0153] (2) The fitting portion includes an electrode plate 311, which is a conductive plate provided on the main body side connection portion 300 and movable between the frame side connection portion 600, and a connector portion 630 provided on the frame side connection portion 600 into which the electrode plate 311 is inserted and removed. Therefore, the work of wiring and disconnecting the external cable becomes unnecessary due to the insertion and removal of the electrode plate 311.

[0154] (3) The electrode plate 311 is provided so as to be movable in the width direction of the housing 200. Therefore, it is possible to accurately position and fit by adjusting the deviation of the electrode plate 311 in the width direction with respect to the connector portion 630.

[0155] (4) The electrode plate 311 is supported by an elastic member. Therefore, the deviation of the electrode plate 311 is absorbed by the elastic member 324.

[0156] (5) The connector portion 630 is provided so as to be movable in the width direction and the height direction of the frame body portion 400. Therefore, the minute deviation at the time of inserting the electrode plate 311 with respect to the connector portion 630 is absorbed.

[0157] The electrode plate 311 and the connector portion 630 are provided separately according to the input / output classification. Therefore, the operator can easily determine which fitting portion to connect or disconnect, facilitating the connection work. Furthermore, by configuring the electrode plate 311 and the connector portion 630 related to grounding to be independently connectable and disconnectable, it is possible to maintain grounding even during replacement and maintenance work of the main body portion 100 and the like, suppressing the risk of electric shock to the operator.

[0158] It has a pressing portion 330 that biases the electrode plate 311 toward the connector portion 630. Therefore, it can be connected to the connector portion 630 without directly touching the electrode plate 311.

[0159] The pressing portion 330 is provided for each input / output classification so that a plurality of electrode plates 311 can be biased together. Therefore, the insertion and extraction of the electrode plates 311 can be performed in batches for each classification, and the burden is lighter compared to the case of inserting and extracting the whole.

[0160] The electrode plate 311 has a holding portion 333 that holds the pressing portion 330 at a distance where electrical insulation from the connector portion 630 is ensured. Therefore, during inspection etc., the state where the power equipment is surely disconnected from the power source is maintained, enabling a safer inspection work. Note that the holding portion 333 may have a structure where a latch for locking the claw is simple and easy to operate, or may be fixed by bolts or the like.

[0161] The pressing portion 330 has a biasing plate 331 that covers a part of the front surface of the connector portion 630, and the biasing plate 331 is formed of a material that allows visual confirmation of the insertion state of the electrode plate 311 with respect to the connector portion 630. Therefore, the connection state of the electrode plate 311 can be easily confirmed.

[0162] It has a guide portion 700 that guides the movement of the main body portion 100 inserted into and removed from the frame body portion 400. Therefore, the movement of the main body portion 100 during insertion and extraction is guided, enabling smooth movement, absorption of errors, and alignment.

[0163] There is a base portion that supports the main body portion 100, intervening between the main body portion 100 and the installation surface. A smooth sheet is attached to the base portion. Therefore, the movement of the main body portion 100 becomes smooth.

[0164] The frame body portion 400 is provided so as to be vertically divisible. Therefore, even if there are space and mass limitations for loading, it can be loaded by dividing it vertically and lifting each part using a suspension bolt or the like.

[0165] (Appearance shape) As the appearance shape of the power panel, various shapes can be considered. Note that the power panel shown below can be regarded as an uninterruptible power supply device panel or an uninterruptible power supply. Also, the main body portion having the housing 200 can be regarded as a power panel, an uninterruptible power supply device panel, or an uninterruptible power supply. Furthermore, the frame body portion 400 can also be regarded as an installation table for a power panel, a support table for a power panel, an installation table for an uninterruptible power supply device panel, or a support table for an uninterruptible power supply device panel.

[0166] The front view, rear view, plan view, right side view, left side view, and bottom view shown below can all be selectively combined to form a power panel, the housing 200, and the frame body portion 400. Note that the lead lines and reference numerals in each figure correspond to the member names in the above-described embodiment and do not constitute the appearance of the power panel.

Also, as shown in the front view of FIG. 50, the door may be a single swing type. Also, as shown in the rear view of FIG. 51, the rear plate may be divided left and right. As shown in the rear view of FIG. 52, the right side view of FIG. 53, and the left side view of FIG. 54, a power panel in which the frame body portion 400 is not vertically divided may also be used.
