Description

Embodiments of the present invention relate to power panels.

An uninterruptible power supply system (UPS) is a system that supplies power of the same standard to a load for a predetermined period of time even if a power supply trouble occurs. An uninterruptible power supply system usually includes a main unit and a peripheral panel, and is installed in a data center or the like. The main body is a main part of the uninterruptible power supply, and includes a rectifier that converts alternating current to direct current, and an inverter that converts direct current to alternating current. Peripheral panels include input transformer panels, storage battery panels, and the like.

The main body and the peripheral board are generally housed in a substantially rectangular parallelepiped-shaped housing. These cases are often arranged in a line along the wall of a data center or the like. Further, the depth and height dimensions of the main body casing and the peripheral board casing are unified from an aesthetic point of view. The dimensions of these casings are, for example, a depth of about 100 cm and a height 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 peripheral panel. Therefore, a work space is provided in front of the main body and peripheral panel. Additionally, the main unit and peripheral panels are updated at the end of their respective expected lifespans. Updating the main unit and peripheral board means replacing the main unit and peripheral board with new ones.

The expected lifespans of the main body and the peripheral panel are different, and there is a large difference in the timing of replacement work for the main body and peripheral panel. Specifically, the expected lifespan of the main body is about 15 years, and the main body is to be replaced 15 years after delivery of the uninterruptible power supply system. On the other hand, the expected lifespan of the peripheral panel is about 25 years, which is about 10 years later than the replacement period for the main unit.

JP2014-222982A

As mentioned above, replacement work for the main unit must be carried out 10 years earlier than for peripheral panels. Therefore, when replacing the main body part, the main body part and the peripheral panel are disconnected, but the peripheral panel itself remains installed. Therefore, when replacing the main unit, it is necessary to remove only the main unit to be replaced from the fixed installation location out of a group of housings lined up in a row, and then reinstall the new main unit in the same location. become.

Since this kind of main body replacement work involves the entire main body, a lot of construction equipment is essential, such as gate-shaped construction equipment that covers the main body and horizontal pulling hooks that can be hung on the main body. . Therefore, the replacement work of the main body was a large-scale work, and the work time was prolonged.

Additionally, data centers do not have a lot of space, so the work space provided in front of the main unit is inherently narrow. Furthermore, when considering the need to bring in construction equipment, the space available for casing replacement work is significantly reduced. Therefore, it is extremely difficult to replace the main body in its casing state, and the problem is that the work efficiency of the construction work is low.

Furthermore, considering the role of the UPS, the shorter the period for replacing the main unit, the better. Therefore, it was necessary to concentrate a large number of workers on the replacement work of the main body, and labor costs soared. As a result, the cost of replacing the main body, including labor costs, increased, and the cost of updating the main body increased.

Of course, there is a desire to suppress the increase in the renewal cost of the main body, but there is also a desire to extend the renewal period of the main body as much as possible. However, if the main body is continued to be used beyond its expected lifespan, there is an increased possibility that a malfunction will occur in the main body. If a problem occurs in the main unit, the effects may extend to peripheral panels connected to the main unit.

For this reason, for example, if you continue to use the main unit far beyond its expected lifespan of 15 years, you may be forced to replace not only the main unit, but also peripheral panels that have not reached their expected lifespan of 25 years. . The scale of replacement work for peripheral panels is extremely large, and extending the time for updating the main unit may actually increase the economic burden.

Considering the above situation, it can be said that ensuring that the main body is updated within its expected life span will lead 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. Particularly in recent years, where the market for renewing the main body has been expanding due to the spread of data centers, reducing the cost of updating the main body has become an urgent need.

In addition to the issues mentioned above when updating the main unit, when carrying out maintenance work on the main unit, replacing it with an alternative machine, etc., a considerable amount of construction time is required and the construction cost is high. The issue is the point. Additionally, because the work is carried out with the surrounding panels left in place, it is often difficult to secure enough space.

As mentioned above, in the case of uninterruptible power supply systems, we explained that there is a difference in the expected lifespan between the main unit and the peripheral panels, but there is often a difference in the expected lifespan between the main unit and the peripheral panels in other power panels as well. Therefore, there are similar issues.

This embodiment was proposed to solve the above problem, and its purpose is to easily replace the main body by attaching and detaching the main body to the frame while leaving the casing intact. Therefore, it is an object of the present invention to provide a power panel that reduces the cost of updating the main body.

In order to achieve the above object, the power panel according to the embodiment of the present invention has the following components (1) and (2).
(1) A main body portion having a casing that accommodates a power device and is placed upright with respect to an installation surface; (2) Of the front portion, back portion and both side portions of the casing, the back portion and a frame portion surrounding the both side portions and to which the casing is attached and detached by being pushed in and pulled out;

(1) First embodiment (configuration)
The power panel of the first embodiment will be specifically explained using FIGS. 1 to 6. This power panel is a panel 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 includes a main body 1, an input transformer board 6, a storage battery board 7, and a branch board 8. The input transformer board 6, the storage battery board 7, and the branch board 8 are also referred to as peripheral boards 6 to 8.

The main body part 1 and the peripheral boards 6 to 8 are housed in a substantially rectangular parallelepiped-shaped housing, and are arranged in a line along a wall surface of a data center or the like. A door is installed in the front of each housing of the main body 1 and the peripheral panels 6 to 8, and the doors are opened to perform maintenance and inspection of the main body 1 or the peripheral panels 6 to 7.

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

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

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

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 backup uninterruptible power supply system, and the main unit 1 includes one standby unit 1a and multiple (three in FIG. 5) regular units 1b. . 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.

(Main unit replacement work)
In the first embodiment as described above, it is possible to replace the main body part 1 by pulling out the main body part 1 as a casing from the frame part 4 and pushing it in. When removing the main body part 1 from the frame part 4, for example, as shown in FIG. The bottom part of the main body part 1 is lifted from the frame part 4 by shallowly tilting it diagonally to the left side of the main body part 4. Next, the worker stands the main body 1 perpendicular to the floor while sliding the lower part of the casing of the main body 1 toward the front (to the left in FIG. 3). Then, the worker slides the entire main body 1 toward the front while maintaining the vertical state of the main body 1, and pulls out the entire main body 1 from the frame 4.

When attaching the main body part 1 to the frame part 4, for example, as shown in FIG. Push it into the frame body part 4. Note that when carrying out the replacement work, a member (not shown), such as a roller, is installed on the bottom surface of the main body 1 to allow the main body 1 to slide smoothly.

(action and effect)
In this embodiment as described above, the main body part 1 has a housing that houses the rectifier 2 that converts AC to DC and the inverter 3 that converts DC to AC, and that is placed upright with respect to the installation surface. It has a frame part 4 that surrounds the back part and both side parts of the front part, back part, and both side parts of the casing, and is attached and detached by pushing and pulling out the casing.

Therefore, the main body part 1 can be easily attached to and removed from the frame part 4 while remaining in the state of the casing, so that the main body part 1 can be easily replaced. Further, when performing maintenance on the main body section 1, the main body section 1 can be pulled out from the frame section 4 and work can be carried out, thereby improving work efficiency.

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

Therefore, when replacing the main body part 1, the work of removing and joining the connecting parts 5a and 5b can be performed simultaneously with the work of attaching and detaching the main body part to the frame part 4. Furthermore, since the main body side connecting portion 5a and the frame side connecting portion 5b are provided on the upper part of the main body portion 1 and the frame body portion 4, the connecting portions 5a and 5b do not become an obstacle when the main body portion is attached or detached. Therefore, the replacement work of the main body part 1 can exhibit excellent work efficiency.

Further, when replacing the main body part 1, construction equipment such as a gate type or a hook for horizontal pulling is not required, and a large space can be secured for replacing the main body part 1. Therefore, it is possible to replace the main body part 1 with the casing intact, and the replacement work can be performed quickly and easily. As a result, construction costs for the main body 1 can be significantly reduced.

In other words, according to the present embodiment, the economic burden when updating the main body 1 can be reduced, so that replacement of the main body 1 can be promoted, and when the main body 1 is used beyond its expected lifespan, It is possible to prevent problems that may occur. 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 malfunction of the main body part 1, and can fulfill their expected lifespans. As a result, the total running cost of the entire uninterruptible power supply system is reduced, improving economic efficiency.

Furthermore, in this embodiment, the display section 10 is arranged at a height of 100 cm or more from the bottom surface of the main body section 1. Therefore, when pushing the main body part 1 into the frame part 4, the operator's hand or the like does not hit the easily damaged display part 10. Therefore, damage to the display section 10 can be reliably prevented, and replacement work for the main body section 1 can be performed safely.

(2) Other aspects (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. In FIG. 7, reference numeral 13 is a parallel board to which a plurality of main body sections 1 are connected. According to this embodiment, the effects of the first embodiment can be obtained even in a parallel redundant uninterruptible power supply system.

(b) In the first embodiment described above, the frame-side connecting portion 5b that is electrically connected to the main body portion 1 and the peripheral panels 6 to 8 is provided on the frame body portion 4 side, but this frame-side connecting portion 5b is Alternatively, the main body side connecting portion 5a on the main body portion 1 side may be directly electrically connected to the peripheral boards 6 to 8 side. According to this embodiment, since there is no need to provide the frame-side connecting portion 5b, the configuration of the frame 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 4. By installing the jig, the stability of the main body portion 1 is increased, so excellent safety can be obtained.
(d) The main body part 1 or the frame part 4 may be provided with an auxiliary mechanism for assisting the drawing operation or the pushing operation of the main body part 1. Providing a work auxiliary mechanism has the advantage of improving work efficiency.

(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 above-mentioned jig, replacement work auxiliary mechanism, or electric shock prevention mechanism, the configuration, shape, material, placement location, number of placement, etc. can be selected as appropriate.

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

(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 sides. In the first embodiment described above, since the frame portion 4 is provided with a back surface portion, the back surface portion can withstand stress, but a reinforcing member may be further provided on the back surface or the like.

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

(h) The shape of the casing of the main body portion 1 may be generalized regardless of its type. When the uninterruptible power supply system has a plurality of main body parts 1, if the replacement timing of the main body part 1 is shifted, the uninterruptible power supply system has an old main body part 1 waiting for replacement and a new main body part 1 that has just been replaced. The problem lies in the fact that there is a mixture of Therefore, by making the shape of the housing of the main body part 1 more general, even if two types of main body parts 1, new and old, coexist in the uninterruptible power supply system, the main body part 1 can be smoothly inserted into the frame part 4. be able to.

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

(j) If the arrangement and configuration of the main body side connecting portion 5a on the main body portion 1 side differ depending on the type of the main body portion 1, an adapter may be interposed between the main body portion 1 and the frame portion 4. In this embodiment, the main body portion 1 can be easily replaced by simply using an adapter.

(3) Second embodiment (configuration)
The power panel of the second embodiment will be specifically explained using FIGS. 8 to 22. This power panel is also a panel applied to an uninterruptible power supply system (UPS). An uninterruptible power supply system including a UPS will be described using 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 includes an input transformer board 6M, a storage battery board 8M, and a main body 9M.

The input transformer board 6M and the storage battery board 8M are external devices of the main body 9M and are also called peripheral boards. In FIGS. 8 and 9, the input transformer board 6M, the main body part 9M, and the storage battery board 8M are installed in this order from the left side of the figure. That is, the main body portion 9M is placed between the input transformer board 6 and the storage battery board 8M from the left and right. The input transformer board 6M, the storage battery board 8M, and the main body part 9M are arranged in a line along the wall surface of a data center, etc., and a base part 7M is installed at the bottom.

FIG. 10 shows a circuit diagram of the main circuit 11M of the UPS provided in the main body 9M. As shown in FIG. 10, the main circuit 11M includes a rectifier 12M that converts AC to DC, and an inverter 13M that converts DC to AC. Such a main circuit 11M is electrically connected to an input transformer board 6M and a storage battery board 8M, which are external devices.

The drawer structure of the uninterruptible power supply according to the second embodiment will be explained using FIGS. 11 to 22. As shown in FIGS. 11 to 22, the main body portion 9M is provided with a housing 10M. The casing 10M can be installed in the form of the casing 10M, that is, without disassembling the casing 10M at all, after electrically disconnecting the input transformer board 6M, the storage battery board 8M, and the main circuit 11M. The structure is such that it can be carried out from the location where it was placed.

In this embodiment, the case 10M is removed from the base part 7M while keeping the form of the case 10M, and the position where the case 10M is installed (the position indicated by the dotted line in FIG. 11), that is, the input transformer board 6M and the storage battery board This is a drawer structure for pulling out the main body part 9M from a position sandwiched between the two parts 8M to a loading/unloading space S of the main body part 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 approximately 1200 mm.

As shown in FIGS. 11 to 15, the casing 10M of the main body portion 9M is provided with a front portion 10Ma, a back 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 back side. A handle 14M is cut out near the center of the side surface 10Mc of the housing 10M. Furthermore, a first mounting hole 1M is provided in the side surface 10Mc of the housing 10M near the front surface 10Ma. The first mounting hole 1M is provided at a position of approximately 200 mm toward the rear surface 10Mb when viewed from the front surface 10Ma (see FIG. 12).

A second mounting hole 2M is provided in the side surface 10Mc of the housing 10M near the back surface 10Mb. The second mounting hole 2M is provided at a position of about 300 mm toward the front part 10Ma when viewed from the back part 10Mb (see FIG. 12).

As shown in FIG. 11, third mounting holes 3M are provided near the left and right ends of the front surface 10Ma of the housing 10M. The third mounting hole 3M is provided at a height of approximately 70 mm from the floor surface when 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 of about 70 mm from the floor surface when the housing 10M is placed on the base portion 7M. The center of gravity of the main body 9M is lower than the middle height of the main body 9M. Therefore, each of the first to third mounting holes 1M to 3M has a height below the center of gravity of the main body portion 9M.

Nuts are housed in the first to third mounting holes 1M to 3M, and as shown in FIGS. 16 to 18 and FIG. 22, eye bolts 4M can be attached to each of the mounting holes 1M to 3M. . Furthermore, when carrying in and out the main body 9M, a removable anchor 15M is installed near the floor of the carrying-out space S. The anchor 15M is arranged perpendicular to the longitudinal direction of the loading/unloading space S. A lever block (registered trademark) 5M, which is a traction tool, is attached to the anchor 15M. The lever block 5M is provided with a hook portion for hooking the eye bolt 4M.

As shown in FIGS. 16 to 18, as well as FIGS. 21 and 22, a rail portion 16M on which the housing 10M can be placed is provided. The rail portion 16M is arranged parallel to the anchor 15M. Note that the reference numeral 17M shown in FIG. 21 is a square piece for receiving a corner of the housing 10M.

(Carrying out the main unit)
Next, the work of carrying out the main body portion 9M will be explained with reference to FIGS. 12 to 19. As shown in FIG. 16, two rail sections 16M are installed in parallel in front of the front section 10Ma of the housing 10M. Although not shown, it is assumed that a curing sheet or the like is spread on the floor of the loading/unloading space S as a prerequisite for performing such work.

An eye bolt 4M is attached to the third attachment hole 3M in the front part 10Ma of the housing 10. Further, an anchor 15M is fixed near the floor of the loading/unloading space S, and a lever block 5 is attached to the anchor 15. Then, hook the hook part of the lever block 5 onto the eye bolt 4M attached to the third mounting hole 3M, operate the lever block 5M, and pull out the casing 10M to the right in FIG. 8 (from FIG. 12 to FIG. 13). transition state).

As shown in FIG. 17, when the first attachment hole 1M of the side surface 10Mc of the housing 10M is exposed by pulling out the housing 10M, the operation of pulling out the housing 10M is temporarily stopped. Then, the hook portion of the lever block 5M is removed from the eyebolt 4M on the third attachment hole 3M side, and the eyebolt 4M is attached to the first attachment hole 1M of the side surface portion 10Mc. By hooking the hook portion of the lever block 5M onto this eye bolt 4M and operating the lever block 5M, the housing 10 is further pulled out to the right in FIG. 16 (state transitioning from FIG. 13 to FIG. 14).

As shown in FIG. 18, the drawing operation is temporarily stopped when the second mounting hole 2M of the side surface 10Mc of the case 10M appears due to further drawing of the case 10M. Then, the hook portion of the lever block 5M is removed from the eyebolt 4M on the first attachment hole 1M side, and the eyebolt 4M is attached to the second attachment hole 2M. By hooking the hook portion of the lever block 5 onto this eye bolt 4M and operating the lever block 5M, the housing 10M is further pulled out to the right in FIG. 17. As a result, the casing 10M is completely lowered from the base portion 7M, and the entire casing 10M is pulled out to the loading/unloading space S (state transitioned from FIG. 14 to FIG. 15).

As shown in FIG. 19, the casing 10M pulled out into the loading/unloading space S is lifted with a jack or the like, and the hand lift 18M is inserted therein. Finally, using the hand lift 18M, the worker H carries the casing 10M to the outside through the carrying-in/out space S, and the carrying-out work of the main body part 9M is completed.

(Transportation of the main body)
The second embodiment is a drawer structure for an uninterruptible power supply, but it can be used not only for carrying out the main body 9M as described above, but also when carrying the main body 9M. Therefore, the work of carrying in the main body portion 9M will be explained using FIGS. 20 to 22. As shown in FIG. 20, a plurality of workers H use a hand lift 18M to carry the casing 10M of the main body part 9M to the front of a predetermined installation position through the loading/unloading space S.

According to the second embodiment, the casing 10M of the main body 9M is pulled out in stages using two types of mounting holes, the first and second mounting holes 1M and 2M. The entire casing 9M can be reliably carried out to the loading/unloading space S without becoming difficult to pull out. Moreover, simply by hooking the lever block 5M onto the eye bolts 4M attached to the mounting holes 1M to 3M and operating the lever block, the main body portion 9M can be carried in and out. Therefore, large-scale construction equipment is not required. As a result, the updating work of the main body portion 9M can be carried out efficiently, and the work cost can be significantly reduced.

In addition, in the second embodiment, since the first to third mounting holes 1M to 3M are all located at a height of around 70 mm from the floor surface, they are provided at a height below the center of gravity of the main body part 9M. It turns out. Therefore, the housing 10M can be stably moved when the main body 9M is carried in and out, and safety during work is improved. Furthermore, in the second embodiment, since the third mounting hole 3M is provided in the front part 10Ma of the casing 10M, the casing 10 can be reliably pulled out from the initial stage of carrying out the main body part 9M. .

Moreover, in the second embodiment, the first to third mounting holes 1M to 3M are all provided near 70 mm from the floor surface, so that the eye bolts 4M attached to these mounting holes 1M to 3M are also located near the floor surface. It is located around 70mm from. The eye bolt 4M at such a height has the advantage that the lever block 5M can be easily attached.

Furthermore, in the second embodiment, by sliding the casing 10M on the rail portion 16M, it is possible to carry out the loading/unloading work of the main body portion 9M quickly. Furthermore, since the handle 14M is provided on the side surface 10Mc of the casing 10M, the operator H can manually carry in and out the main body 9M by using the handle 14M. Therefore, it is possible to handle the work of loading and unloading the main body 9M under all conditions.

(4) Other aspects For example, the configuration, shape, location, etc. of the first to third mounting holes 1M to 3M can be changed as appropriate. Further, in the embodiment described above, the lever block 5M is used for carrying in and out the main body 9M, but the power for carrying in and out the main body 9M can be selected as appropriate. Alternatively, a sliding sheet may be pasted on the rail portion 16M so that the housing 10M can be easily slid onto the rail portion 16M. In this embodiment, it becomes possible to carry out the work of carrying in and out the main body part 9M more easily.

Furthermore, similarly to the first embodiment and the third and fourth embodiments described later, the casing 10M is installed in a removable manner with respect to a frame portion surrounding the back surface and both side surfaces of the casing 10M. The casing 10M may be pulled out from the casing 10M. In this embodiment, even after the casing 10M of the main body 9M is pulled out, the frame remains between the input transformer board 6M and the storage battery board 8M. The frame body can receive the pressure.

Therefore, when the casing 10M is pulled out, no pressure is applied to the casing 10M from the input transformer board 6M and the storage battery board 8M, and it is possible to carry out the work of carrying out the main body 9M smoothly. Moreover, there is no fear that the input transformer board 6M and the storage battery board 8M will fall into the space after the housing 10M is pulled out, even if slightly, and the space becomes narrow. Therefore, the work of carrying in the main body portion 9M can be carried out reliably.

The uninterruptible power supply system shown in Fig. 25 is a common standby UPS system, and the main unit 1N is provided with one standby unit 10Na and multiple (two in Fig. 25) regular units 10Nb and 10Nc. . That is, the third embodiment is applied to a common standby UPS system. The main body portion 1N is provided with a rectifier 2N that converts AC to DC, and an inverter 3N that converts DC to AC. In addition, in FIG. 25, the part surrounded by the thick two-dot chain line is the main body part 1N, and the part surrounded by the one-dot chain line is the frame body part 4N.

As shown in FIGS. 26 to 30, the main body 1 is a rectangular parallelepiped-shaped housing, and has a front part, a back part, a top part, a bottom part, and left and right side parts. The main body portion 1N is detachably installed on the frame portion 4N. The frame part 4N has no front part and top part, and has a bottom part, left and right side parts, and a back part connecting the side parts, and supports the main body part 1 from the left and right and from below. When the main body part 1 is attached to the frame part 4N, the back surface of the main body part 1N and the back surface of the frame part 4N are brought into contact with each other. These back portions that come into contact with each other are referred to as contact surfaces 11N and 41N of the main body portion 1N and the frame portion 4N.

As shown in FIGS. 26 to 30, the main body portion 1N is provided with a main body side connecting portion 5Na above the contact surface 11N.

In this case, by installing the external connection part 5Nc below the frame side connection part 5Nb, connection at each connection part becomes simple.

(Body side connection part and frame side connection part)
The main body side connecting portion 5Na and the frame side connecting portion 5Nb are arranged to face each other. When the main body side connecting portion 5Na is not joined to the frame side connecting portion 5Nb, it is arranged at a retracted position P1 sufficiently away from the frame side connecting portion 5Nb so as not to contact the frame side connecting portion 5Nb on the frame body portion 4N side. has been done. The retracted position P1 is provided near the front of the main body portion 1N.

Further, the position where the main body side connecting portion 5Na and the frame side connecting portion 5Nb are joined is defined as a joining position P2. FIG. 30 shows a state in which the main body side connecting portion 5Na has moved to the joining position P2. The main body side connecting portion 5Na is configured to move linearly between the retracted position P1 and the joining position P2. When the main body side connecting portion 5Na is separated from the frame side connecting portion 5Nb, the two are electrically disconnected.

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

The four connection parts A and B are two 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 storage battery panel 7N side. The fact that there are four first connection parts A means that there are also four main body side connection parts 5Na. Although the four main body side connecting portions 5Na are located at different positions in the circuit diagram, they are attached to the same member and are movable as one unit.

Further, in FIG. 25, numerals 12Nb and 13Nb indicate higher-order molded circuit breakers in the regular machine 10Nb, and symbols 14Nb and 15Nb indicate lower-order molded circuit breakers in the regular machine 10Nb. Further, numerals 12Nc and 13Nc indicate higher-order molded circuit breakers in the regular machine 10Nc, and 14Nc and 15Nc indicate lower-order molded circuit breakers in the regular machine 10Nc. The molded 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. Moreover, the molded circuit breakers 15Nb and 15Nc are connected to the standby device 10Na side.

Furthermore, as shown in FIGS. 26 to 30, a work space 9N is provided near the front of the main body 1N when viewed from the retracted position P1 of the main body side connecting portion 5Na. The work space 9N is used for joining or separating the main body side connection part 5Na and the frame side connection part 5Nb.

(Main unit update work)
In the third embodiment as described above, the operation of removing the main body part 1N from the frame part 4N will be explained. For example, when removing the service machine 10Nb from the frame portion 4N, the molded circuit breakers 12Nb to 14Nb are opened and the molded circuit breaker 15Nb is closed. As a result, the power supply from the commercial power supply and the standby machine 10Na to the regular machine 10Nb is stopped, so that the main body 1N of the regular machine 10Nb becomes removable. Furthermore, the standby machine 10Na will supply UPS power to the load to which the regular machine 10Nb has been supplying power.

On the other hand, when the regular machine 10Nc is to be removed from the frame portion 4, the molded circuit breakers 12Nc to 14Nc are opened and the molded circuit breaker 15Nc is turned on. As a result, the power supply from the commercial power supply and the standby machine 10Na to the regular machine 10Nc is stopped, so that the main body 1N of the regular machine 10Nc becomes removable. Furthermore, the standby machine 10Na will supply UPS power to the load to which the regular machine 10Nc has been supplying power.

After performing the above operations, the update worker uses the work space 9N to perform the detachment work from the main body side connection part 5Na on the main body part 1N side and the frame side connection part 5Nb on the frame body part 4N side. . Therefore, the main body side connecting portion 5Na and the frame side connecting portion 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 separated, the main body part 1N is removed from the frame body part 4N by pulling out the main body part 1N from the frame body part 4N.

Next, the work of attaching the new main body part 1N to the frame part 4N will be explained. Push the new main body part 1N into the frame part 4N, and the abutment surface 11N of the back part of the main body part 1N and the abutment surface 41N of the back part of the frame part 4N abut each other, thereby positioning them. will be done. 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 body part 4N side.

Next, the update worker uses the work space 9N to move the main body side connecting part 5Na from the retracted position P1 to the joining position P2, and connects the main body side connecting part 5Na and the frame side connecting part on the frame body part 4N side. Perform bonding work with 5Nb. Thereby, 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 whether the main body part 1N is attached or detached, 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 attaching the regular machine 10Nb to the frame portion 4, the molded circuit breakers 12Nb to 14Nb are closed and the molded circuit breaker 15Nb is opened and closed. On the other hand, when the regular machine 10Nc is attached to the frame portion 4N, the molded circuit breakers 12Nc to 14Nc are turned on and the molded circuit breaker 15Nc is opened. As a result, power supply to the regular machines 10Nb and 10Nc from the commercial power source and the standby machine 10Na is restarted, and the state returns to the state where the regular machines 10Nb and 10Nc supply UPS power to the loads.

(effect)
In the third embodiment, a main body part 1N houses a rectifier 2N that converts AC to DC and an inverter 3N that converts DC to AC inside a housing, and a frame part 4N in which the main body 1N is removably installed. A movable contact part 5Na is provided on the main body part 1N side, and a frame side connection part 5Nb that can be electrically connected to and separated from the main body side connection part 5Na, and an external device is provided on the frame part 4N side. An external connection part 5Nc electrically connected to the external connection part 5Nc is provided.

(a) According to the third embodiment, when the main body portion 1N is removed from the frame portion 4N, the frame side connection portion 5Nb and the external connection portion 5Nc installed on the frame portion 4N side are It is possible to maintain the bonded state. Therefore, there is no need to disconnect the electrical connection between the peripheral panels 6N to 8N, which are external devices, and the frame portion 4N, and the updating work can be easily carried out.

The external cables that electrically connect the main unit 1N side and the peripheral panels 6N to 8N are deformed due to heat after the start of operation, so once they are removed, it is almost impossible to reconnect them. Therefore, when updating the main unit 1N, with the conventional technology in which the electrical connections with the peripheral panels 6N to 8N, which are external devices, are removed, it is also necessary to replace the external cable, which increases the update cost. .

On the other hand, in the third embodiment, there is no need to disconnect electrically between the peripheral boards 6N to 8N and the frame portion 4N. Therefore, even after updating the main body part 1N, the existing external line cable, which is the external connection part 5Nc, can be used, and there is no need to replace it. As a result, the renewal cost can be significantly reduced, which is economically advantageous.

(b) Normally, the weight of the main body part 1N is quite heavy, and when the main body part 1N is strongly pushed into the frame part 4N, if the main body side connection part 5Na and the frame side connection part 5Nb collide, the connection parts 5Na, 5Nb may be damaged. Therefore, in the third embodiment, if the main body part 1N is detached from the frame part 4N, the main body side connecting part 5a is located at the retracted position P1.

Therefore, even if the main body part 1N is strongly pushed into the frame part 4N during the work of attaching the main body part 1N to the frame part 4N, the contact surfaces 11N, 41N of the main body part 1N and the frame part 4N The main body side connecting portion 5Na and the frame side connecting portion 5Nb do not directly collide with each other. 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 update work.

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

(d) In the third embodiment, the main body side connecting portion 5Na and the frame side connecting portion 5Nb are arranged so as to be able to freely approach and separate even when the main body portion 1N is pushed into the frame portion 4N. Therefore, the main body side connection part 5Na functions as a disconnector, and safe work is possible by disconnecting the main body side connection part 5Na and the frame side connection part 5Nb during maintenance of the main body part N1.
(e) In the third embodiment, the above effects can be obtained in the common standby UPS system.

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

In this embodiment, the main body section 1N is removed from the frame section 4 after the molded circuit breakers 17N and 18N connected to the main body section 1N to be removed are opened. Moreover, when attaching the main body part 1N to the frame part 4N, the main body part 1N is attached to the frame part 4N and then the circuit breakers 17N and 18N are turned on. According to the above embodiment, the effects of the third embodiment can be obtained in the parallel redundant uninterruptible power supply system.

A guide member, such as a guide rail portion, for pulling out or pushing the main body portion 1N from the frame portion 4N may be provided. The guide member may be provided on the side surface or bottom surface of the main body portion 1N, or may be provided on the side surface or bottom surface portion of the frame portion 4N. The configuration, shape, material, placement location, number of placement, etc. of such guide members can be changed as appropriate.

In the third embodiment, the internal connection portion on the main body portion 1N side is the main body side connection portion 5Na, which is a movable connection portion, but the frame side connection portion 5Nb on the frame body portion 4N side may be a movable connection portion. The movable direction of these movable connecting portions is not limited to the direction in which the main body portion 1N is attached to and removed from the frame portion 4N. For example, one connection part may be disposed facing upward, and the other connection part may be moved to cover this connection part from above to connect.

[Body side connection part]
The main body side connection section 300 is a component that performs electrical connection with an outside line connection section 600, which will be described later. The main body side connection section 300 has an electrode section 310, a support section 320, and a presser section 330, as shown in FIGS. 34 to 37.

(electrode part)
The electrode section 310 has an electrode plate 311 and a flexible conductor 312, as shown in FIG.

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, which will be described later. The lower part of the electrode plate 311 is a vertical support surface 311a extending from the upper part of the housing 200 downward to the rear 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 the relay surface 311c in the front-rear direction, the electrode plate 311 has a crank shape as a whole.

The flexible conductor 312 is a member in which a pair of conductive terminals 312a and 312b are connected by a flexible member 312c that is a flexible conductor. One terminal 312a of the flexible conductor 312 is connected to a lead-out terminal 220 on the back surface 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.

(Support part)
The support portion 320 is a component that supports the electrode plate 311 on the housing 200 while allowing movement in the depth direction and width direction. The support section 320 has a guide rail 321, a slider 322, a movable section 323, and an elastic member 324, as shown in FIG.

The guide rail 321 is an elongated member having a substantially U-shaped cross section with an opening on the back side of the housing 200 . The guide rail 321 is attached in the width direction of the housing 200.

One end of each elastic member 324 is inserted into a 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.

The above configuration of the support section 320 allows the electrode plate 311 to move in the width direction of the housing 200 together with the slider 322 that moves along the guide rail 321. Furthermore, the elastic member 324 can move in the depth direction of the housing 200 together with the elastic member 324 that moves along the guide hole 323c. When the electrode plate 311 is biased toward the back side, the contact/separation surface 311b fits into a clamping body 632, which will be described later. Note that even if the position of the electrode plate 311 with respect to the lead-out terminal 220 is shifted, conduction is ensured by the deformation of the flexible conductor 312.

As shown in FIG. 35, a plurality of electrode plates 311 are prepared for each section. For example, there are four in the DC input section E1, three in the AC input section E2, three in the bypass input section E3, and four in the AC output section E4. For DC input, two positive electrodes and two negative electrodes are supported. AC input and bypass input correspond to 3 phases. For AC output, it supports 3 phases and a ground wire.

The enclosing portion 500 is a member that surrounds both sides and the back of the housing 200 in a U-shape. The enclosing portion 500 has an upright body 510 and a side body 520.

The upright body 510 is a thin casing that stands upright on the installation surface. The height of the vertical body 510 is set to be 20 to 25% higher than the casing 200. The front surface of this raised portion becomes a protrusion 511 that protrudes upward when the housing 200 is housed. The vertical body 510 is provided so as to be vertically separable with a straight line in the width direction as a boundary.

The side bodies 520 are members that extend from both side edges of the upright body 510 to the front side at right angles to the upright body 500 to cover the side surfaces of the housing 200 housed therein. The side body 520 is configured by stacking two rectangular U-shaped frames 521 and 522 one above the other. The centers of the upper and lower horizontal parts of the frames 521 and 522 are connected by vertical columns 521a and 522a.

(Frame side connection part)
The frame-side connection section 600 is a component that electrically connects to an external line cable via the main body-side connection section 300. As shown in FIGS. 38 and 39, the frame-side connecting portions 600 are arranged side by side in the width direction in front of the protruding portion 511. The frame-side connection portion 600 includes a fixing plate 610, an external line terminal 620, a connector portion 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, an operator cannot touch the connection part while the power is being applied. It is possible to ensure safety so that this does not occur. This cover CB can be made of a metal material, although the insulation distance can be made longer by using an insulating material such as resin.

Additionally, after the start of operation, the connected portion may be imaged with a thermo camera to check whether abnormal temperatures have been reached. Therefore, by providing a hinge or the like at the connection point between the frame portion 400 and the cover CB, the cover CB can be easily opened and closed during inspection, thereby improving work efficiency. Further, by providing a hole in the cover CB so that the connection portion can be seen from the front of the main body 100, inspection using a thermo camera becomes easy.

The fixed plate 610 is a rectangular conductive plate. The fixed plate 610 is supported and fixed to the front surface of the protrusion 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.

The external line terminal 620 is a conductive plate, and has 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 fixed plate 610. The other surface of the external line terminal 620 protrudes toward the front side, and has a hole 621 formed therein for connection to a terminal of an external line cable.

The connector portion 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 into each other, thereby forming a fitting part that is electrically connected. The connector section 630 includes a mounting plate 631, a holding 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 fixed plate 610. The holding 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 holds the inserted electrode plate 311 in the width direction.

Further, the holding body 632 is attached to the mounting plate 631 so as to be movable in the height direction and the width direction of the housing 200, and is urged to a fixed position by an elastic member (not shown). This guide width can be, for example, several millimeters in the height and width directions. As a result, the holding body 632 constitutes a floating connector in which the recess 611 follows the position of the electrode plate 311 when the electrode plate 311 is inserted, and can absorb the positional deviation between the electrode plate 311 and the recess 632a.

The contact electrode 633 is a conductor that comes into contact with the electrode plate 311 inserted into the recess 611 and is electrically connected. The contact electrode 633 is electrically connected to the outside line terminal 620 via the mounting plate 631 and the fixing plate 610.

A plurality of such holding bodies 632 of the connector portion 630 are arranged with respect to one electrode plate 311. In this embodiment, three clamping bodies 632 are provided. The contact electrodes 633 of this sandwiching body 632 share the rated current equally. For example, when the rated current is 300A, a current of about 100A can be passed. However, it is also possible to use a single clamping body 632 that carries the rated current.

As shown in FIGS. 38 and 39, the fixed leg 640 is fixed to the upright body 510 and is placed in a position to prevent the electrode plate 311 from coming off by attaching a biasing plate 331 that presses the electrode plate 311. This is a holding plate.

The fixed leg 640 has an end on the back side attached to the front side of the protrusion 511 of the upright body 510, and extends forward. The front end of the fixed leg 640 is bent in a direction parallel to the back surface, and has an attachment hole 641 for attaching the biasing plate 331.

The number of frame-side connecting portions 600 arranged as described above corresponds to the number of lead-out terminals 220 divided into a plurality of types of input/output sections. For example, there are four in the DC input section E1, three in the AC input section E2, three in the bypass input section E3, and four in the AC output section E4.

(Guide part)
The guide section 700 is a component that guides movement of the main body section 100 inserted into and removed from the frame section 400. The guide section 700 has a guide roller 710, as shown in FIG. The guide roller 710 has a shaft 711 and a roller 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 having a shaft member 711 fixed to the central axis. A plurality of guide rollers 710 are arranged inside the both side bodies 520 in the depth direction. The side surface of the roller 710 protrudes inward and comes into contact with and separates from the side surfaces 203 and 204 of the main body section 100 being inserted and removed.

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

A smooth sheet 820 is attached to the bottom surface of both short sides of the base portion 800 and the bottom surface of the bridging plate 810. As the sheet 820, for example, an ultra-high molecular weight polyethylene tape is used. The surface of the base section 800 to which the sheet 820 is attached is in contact with the installation surface, and the casing 200 of the main body section 100 is placed on the opposite surface. Note that a smooth sheet similar to the sheet 820 is also attached to the bottom surface of the casing 200.

(Installation work)
The work of installing the frame section 400 and main body section 100 as described above will be explained. First, the frame body part 400 is installed between adjacent boards as shown in the above embodiment. In addition, when carrying in and carrying out the frame body part 400, as shown in FIG. 39, it can be divided|segmented into the upper enclosure part 500A and the lower enclosure part 500B, and can be conveyed. At this time, the lifting bolts R can be fastened to the respective bolt holes 521b and 522b of the upper surrounding part 500A and the lower surrounding part 500B to lift it up. This allows movement even in places with height restrictions, such as in elevators.

The work of attaching and detaching the main body part 100 to the frame part 400 is the same as in the second embodiment. That is, the housing 200 can be taken in and out of the frame part 400 using the eye bolts 4M attached to the base part 800 and the first to third mounting holes 1M to 3M. Note that when the housing 200 placed on the base part 800 is taken in and taken out, the base part 800 slides on the installation surface by the seat 820 provided on the base part 800, so that the case 200 can be taken in and taken out smoothly. In addition, since the roller 712 of the guide roller 710 rotates in contact with the lower portions of the side surfaces 203 and 204 of the housing 200, the housing 200 can be smoothly inserted and removed.

After the main body section 100 is attached to the frame section 400, an external line cable is connected to the frame side connection section 600. A bolt is passed through the terminal hole provided at the tip of the external line cable and the hole 611 of the external line terminal 620, and then tightened and fixed with a nut.

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

The operator holds the handle 332 of the biasing plate 331 of the presser part 330 and moves it in the width direction to adjust the widthwise position of the electrode plate 311 and the clamping body 632, and then as shown in FIG. Then, push the biasing plate 331 toward the back side. The pressure at the time of pushing is relieved by the elastic members 331a and 611. Then, as shown in FIG. 41, the contact/separation surface 311b of the electrode plate 311 fits into the recess 632a of the holding body 632, contacts the contact electrode 633, and is electrically connected.

At this time, a slight misalignment 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 a floating connector. The operator uses the attachment hole 331a to fix the biasing plate 331 to the fixed leg 640 with bolts, as shown in FIG. 37. As a result, the external line cable is connected to the UPS via the main body side connection section 300 and the frame side connection section 600.

In addition, when releasing the connection between the main body side connection part 300 and the frame side connection part 600, remove the bolt fixation between the biasing plate 331 and the fixed leg 640, hold the handle 332, and pull it toward the front side. Then, the plate 311 is removed from the recess 632a of the holding body 632, and the electrical connection is released.

By engaging the holding part 333 of the holding part 330 with a claw in a hole provided on the upper surface of the housing 200, the position of the biasing plate 331 is changed to a disconnected state in which the electrode plate 331 is separated from the clamping body 632. can be retained.
