[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-09310 Summary of the Invention [Problem to be solved by the invention]

[0004] Because the battery unit is heavy, it is important to reduce the burden on workers by making it easy to remove by pulling it out of the housing when replacing it. Also, care must be taken to prevent the movement of the harness when inserting and removing it. [Means for solving the problem]

[0005] The uninterruptible power supply comprises a housing, a storage battery unit, a slide plate attached to the housing so as to be slidable in a first direction and supporting the storage battery unit so as to be slidable relative to the housing, a power unit housed in the housing, a harness electrically connecting the storage battery unit to the power unit, and a following member that causes the harness to follow in the first direction as the storage battery unit moves in the first direction. [Effects of the Invention]

[0006] This invention allows the heavy battery unit to be easily removed from the housing during replacement, reducing the burden on the worker. Furthermore, since the harness moves along with the battery unit when it is inserted or removed from the housing, it is possible to prevent the harness from getting tangled around surrounding components.

[0008] (Outline of this embodiment) (1) An uninterruptible power supply according to one embodiment of the present invention comprises a housing, a storage battery unit, a slide plate attached to the housing so as to be slidable in a first direction and supporting the storage battery unit so as to be slidable relative to the housing, a power unit housed in the housing, a harness electrically connecting the storage battery unit to the power unit, and a follower member causing the harness to follow in the first direction as the storage battery unit moves in the first direction. In the uninterruptible power supply described in (1), any configuration other than the above is optional and may be used.

[0009] According to an uninterruptible power supply according to one embodiment of the present invention, the heavy battery unit can be easily removed by pulling it out of the housing during replacement, thereby reducing the burden on the worker. Furthermore, since the harness moves along with the battery unit when it is inserted or removed from the housing, it is possible to prevent the harness from becoming entangled in surrounding components.

[0010] (2) In the uninterruptible power supply described in (1) above, the housing may include a support member that slidably supports the slide plate. The follower member may be a rail chain with one end fixed to the slide plate and the other end fixed to a support member of the housing. In the uninterruptible power supply described in (2), any configuration other than the above is optional and may be any configuration.

[0011] In this configuration, the rail chain moves in accordance with the slide plate, allowing the harness to follow the movement of the storage battery unit.

[0012] (3) In the uninterruptible power supply described in (2) above, the battery units may be mounted in front of and behind the slide plate in the first direction. The rail chain may be installed corresponding to the rear battery unit. In the uninterruptible power supply described in (3), any configuration other than the above is optional and may be used.

[0013] (3) When two battery units are arranged on the front and rear of a sliding plate, the front battery unit gets in the way of the rear battery unit, and it can be difficult to release the connector attached to the end of the harness until the front battery unit is removed. If the battery unit is removed with the connector still connected, the harness may be pulled along with it and become entangled in surrounding components. By applying this technology to the rear battery unit, there is no need to worry about the harness connected to the rear battery unit becoming entangled in surrounding components even when the sliding plate on which the battery unit is mounted is removed from the housing.

[0014] (4) The uninterruptible power supply according to any one of (1) to (3) above may further include a restraining member that restrains the vertical displacement of the storage battery unit relative to the slide plate. In the uninterruptible power supply according to (4), any configuration other than the above is optional and may be any configuration.

[0015] When transporting the uninterruptible power supply, the battery unit can be prevented from moving up and down and interfering with surrounding components. In addition, when the battery unit is pulled out of the housing, the vertical movement is restricted, allowing for stable removal.

[0016] <Embodiment> 1. Overall configuration of uninterruptible power supply 10 This embodiment shows a continuous inverter type uninterruptible power supply 10 that is installed indoors. FIG.

[0017] The uninterruptible power supply 10 includes an input / output unit 30, a transformer 36, a transformer 40, a transformer 43, power units 50A to 50C, storage battery units 70A to 70C, and a control unit 80 as an electrical configuration.

[0018] The input / output unit 30 has a first input terminal 31, a second input terminal 32, a first output terminal 33, a second output terminal 34, a breaker 35, a lightning arrester 38, a plurality of circuit breakers 37A, 37C to 37H, and an electromagnetic contactor 37B.

[0019] The first input terminal 31 is for AC input (210V / 240V) and is connected to a primary winding 41A of a transformer 40 via a breaker 35, a transformer 36, and a circuit breaker 37A. The transformer 36 is for stepping down (210V / 240V to 100V). The transformer 40 is a three-winding type and has two secondary windings 42A and 42B.

[0020] Power units 50A to 50C are connected in parallel to secondary winding 42A of transformer 40. Power units 50A to 50C are connected to first output terminal 33 via electromagnetic contactor 37B, circuit breaker 37C, and circuit breaker 37D.

[0021] The second output terminal 34 is connected in parallel to the first output terminal 33 via a circuit breaker 37E and a transformer 43. The first output terminal is for outputting 100 V, and the second output terminal is for outputting 200 V. The transformer 43 is for stepping up (100 V to 200 V).

[0022] Storage battery units 70A to 70C are connected to power units 50A to 50C, respectively. Since power units 50A to 50C have the same configuration, the following description will be given using power unit 50A as an example.

[0023] 2 is a block diagram of the power unit 50A. The power unit 50A includes a noise filter 51, a first capacitor 52, an electromagnetic contactor 53, a first choke coil 54, a converter 55, a link capacitor 56, an inverter 57, a second choke coil 58, a second capacitor 59, an electromagnetic contactor 60, a noise filter 61, a charger 63, and a fan 65.

[0024] First capacitor 52 and first choke coil 54, and second choke coil 58 and second capacitor 59 are LC filters. Charger 63 is used to charge storage battery unit 70A. Fan 65 is used to cool converter 55 and inverter 57.

[0025] Power unit 50A converts AC input from transformer 40 to DC using converter 55, then converts the DC to AC using inverter 57 and outputs it to the load. During a power outage, power can be supplied to the load by generating AC using inverter 57 using storage battery unit 70A as the power source.

[0026] 1, the lightning arrester 38 is connected to the first input terminal 31 via a circuit breaker 37F, and serves to protect the uninterruptible power supply 10 from surges caused by lightning strikes and the like. The second input terminal 32 is connected to a primary winding 41A of the transformer 40 via a circuit breaker 37G. The second input terminal 32 is for emergency input (100V), and AC input is also possible via the second input terminal 32.

[0027] Furthermore, two maintenance paths L1 and L2 are provided in the uninterruptible power supply 10. An AC switch 39 is installed on the maintenance path L1, and a circuit breaker 37H is installed on the second maintenance path L2.

[0028] The first maintenance path L1 connects the secondary winding 42B of the transformer 40 to point B in FIG. 1, and allows power to continue to be supplied to the load even during maintenance of the power units 50A to 50C.

[0029] The second maintenance path L2 connects points A and C in FIG. 1, and allows power to continue to be supplied to the load even while the transformer 40 is being maintained.

[0030] The control unit 80 is connected to each of the power units 50A to 50C via a communication line LC, and controls the output of each of the power units 50A to 50C.

[0031] FIG. 3 is a front view of the uninterruptible power supply 10, FIG. 4 is a perspective view of the uninterruptible power supply 10, and FIG. 5 is a diagram showing the internal structure of the uninterruptible power supply 10. As shown in FIG.

[0032] 3 is referred to as the X direction, the up-down direction as the Y direction, and the direction perpendicular to the paper surface as the Z direction. The Z direction is the front-to-rear direction of the uninterruptible power supply 10 (corresponding to the "first direction" of the present invention), and in this embodiment, the opening side (the front right side in FIG. 4) is referred to as the front side, and the opposite side (the rear left side in FIG. 4) is referred to as the rear side.

[0033] As shown in FIGS. 3 to 5, the uninterruptible power supply 10 includes a housing 100, an input / output unit 30, transformers 36, 40, and 43, power units 50A to 50C, storage battery units 70A to 70C, and a control unit 80.

[0034] The housing 100 is made of, for example, metal. The housing 100 is box-shaped and long in the Y direction (vertical direction), and has a frame 101, a left side wall 111, a right side wall 112, a rear wall 113, a front wall 115, a bottom wall 116, and a top wall 117, as shown in FIGS.

[0035] Frame 101 is a frame type and has four support columns 102A to 102D, multiple connecting plates 103, and multiple reinforcing plates 104. Connecting plates 103 connect the tips of support columns 102 together, and reinforcing plates 104 connect the support columns at positions closer to the center.

[0036] The front wall 115 is a door that can be opened and closed via a hinge. A cooling fan 118 is installed on the ceiling wall 117.

[0037] As shown in Figures 3 to 5, in this embodiment, storage battery units 70A to 70C are housed in a vertically stacked state in the lower part of the housing, and a terminal block 30A that constitutes the input / output unit 30 is installed to the side thereof.

[0038] The breaker unit 30B, control unit 80, and power units 50A to 50C that make up the input / output unit 30 are arranged in the upper part of the housing. The transformer 43 is arranged behind the terminal block 30A, and the transformers 40 and 36 are arranged behind the breaker unit 30B.

[0039] <Support structure of storage battery units 70A to 70C> The uninterruptible power supply 10 has a slide structure 150. The slide structure 150 is a structure that supports the storage battery units 70A to 70C relative to the housing 100 so that they can slide in the front-to-rear direction.

[0040] 6 is a perspective view of the sliding structure 150. The sliding structure 150 is composed of a sliding plate 160, a support frame 170, a rail chain 210, etc. The support frame 170 is an example of a "support member" in the present invention, and the rail chain 210 is an example of a "following member" in the present invention.

[0041] 7 is a perspective view showing the structure of the support frame 170. The support frame 170 is generally frame-shaped and is attached to the frame 101 of the housing 100.

[0042] The support frame 170 includes a first frame 171, a second frame 172, a front wall 175, an intermediate wall 176, a rear wall 177, and the like.

[0043] The first frame 171 and the second frame 172 extend parallel to each other in the front-to-rear direction (Z direction). A front wall 175 connects the front ends of the first frame 171 and the second frame 172. A middle wall 176 connects the middle parts of the first frame 171 and the second frame 172, and a rear wall 177 connects the rear ends of the first frame and the second frame.

[0044] The first frame 171 and the second frame 172 have vertical walls 171A and 172A. The vertical walls 171A and 172A have rollers 173 on their inner surfaces, and support the slide plate 160 so that it can slide in the front-rear direction (Z direction).

[0045] The slide plate 160 is made of, for example, metal and has a shape that is long in the front-to-rear direction (Z direction). In this embodiment, a total of four (2 x 2) storage battery units 70A-1 to 70A-4 can be mounted on the slide plate 160 on the left and right and front and back.

[0046] By sliding the slide plate 160 relative to the support frame 170, the storage battery unit 70A can be pulled out toward the front of the housing, as shown in FIG.

[0047] Specifically, the front storage battery units 70A-1 and 70A-2 can be pulled out to the front of the housing, and the rear storage battery units 70A-3 and 70A-4 can be pulled out to the front end of the housing. The slide plate 160 is an example of a slide member.

[0048] 8 is a perspective view of the storage battery unit 70A, and FIG. 9 is an exploded perspective view of the storage battery unit 70A. The storage battery unit 70A is composed of a unit base 71, a plurality of storage batteries 75A to 75F, and an upper plate 76.

[0049] The unit base 71 has a shape that is long in the front-to-rear direction (rectangular in plan view) and has a flange 72 along its outer periphery. A first mounting portion 73 is provided at the front end, and a second mounting portion 74 is provided at the rear end. The second mounting portion 74 has a first wall 74A that bends forward at the center of its upper end.

[0050] Upper plate 76 is located on the top surface of storage batteries 75A to 75F. Upper plate 76 has a shape that is long in the front-rear direction (rectangular in plan view) and has flanges 77 on both the left and right sides. It also has a first attachment portion 78 at its front end and a second attachment portion 79 at its rear end.

[0051] The first mounting portion 78 is L-shaped and has a vertical first wall 78A and a horizontal second wall 78B. The first mounting portion 78 (specifically, the first wall 78A) corresponds to the first mounting portion 73 of the unit base 71, and the second mounting portion 79 corresponds to the second mounting portion 74 of the unit base 71 (specifically, the first wall 74A).

[0052] By fastening the upper plate 76 to the unit base 71 with screws, the plurality of storage batteries 75A to 75F can be fixed to the unit base 71 and unitized.

[0053] The upper plate 76 also serves as a holder for holding the connector 200A and the harness P1. More specifically, as shown in Figures 8 and 9, a flange 77 of the upper plate 76 is provided with hooks 77A to 77C.

[0054] In addition, a connector 200A is attached to the first attachment portion 78 of the upper plate 76 via a plate portion 78C, and a harness P1 that connects the connector 200A to the storage batteries 75A to 75F is held on the upper plate 76 by hooks 77A to 77C.

[0055] As shown in FIG. 10, the slide plate 160 has a flat base 161 , a front wall 162 , a rear wall 163 , a right side wall 165 , and a left side wall 166 .

[0056] Additionally, four pairs of guide members 167, 168 are arranged on the top surface of base 161 corresponding to four storage battery units 70A-1 to 70A-4 (only two pairs are shown in FIG. 10).

[0057] Guide members 167 and 168 have an L-shaped cross section and are arranged facing each other in the X direction. The installation interval between guide members 167 and 168 corresponds to the dimension of storage battery units 70A-1 to 70A-4 in the X direction.

[0058] The guide members 167 and 168 regulate the position of the storage battery unit 70A in the X direction on the slide plate 160, preventing adjacent storage battery units 70A from shifting in the X direction and interfering with each other.

[0059] 11, the guide members 167 and 168 act as guides when the rear storage battery units 70A-3 and 70A-4 are pulled forward on the slide plate 160.

[0060] 12, the slide plate 160 has a front plate 180 and an intermediate plate 190. The front plate 180 and the intermediate plate 190 are members that fix the storage battery unit 70A to the slide plate 160A.

[0061] Specifically, the front plate 180 is located at the front of the slide plate 160 and is attached to the front wall 162 of the slide plate 160 with screws.

[0062] The front plate 180 has two retaining portions 181A and 181B corresponding to the two storage battery units 70A-1 and 70A-2 mounted on the front side of the slide plate 160.

[0063] The two pressing portions 181A and 181B are bent in a U-shape and are adapted to overlap the upper surfaces of the first mounting portions 73 of the storage battery units 70A-1 and 70A-2, respectively.

[0064] The intermediate plate 190 is located approximately in the center of the sliding plate 160 in the front-to-rear direction, and is positioned midway between the storage battery units 70A-1 and 70A-2 mounted on the front side of the sliding plate 160 and the storage battery units 70A-3 and 70A-4 mounted on the rear side.

[0065] The intermediate plate 190 is in the shape of a vertical plate, and has three pressing portions 191A, 191B, and 191C at its upper end portion. The three pressing portions 191A, 191B, and 191C are bent forward.

[0066] As shown in Figure 12, the clamping portion 191A and the clamping portion 191B overlap the upper surface of the second mounting portion 79 of the upper plate 76 attached to the storage battery unit 70A-1, and the clamping portion 191B and the clamping portion 191C overlap the upper surface of the second mounting portion 79 of the upper plate 76 attached to the storage battery unit 70A-2.

[0067] In this way, by pressing the front and rear ends of the battery units 70A-1 and 70A-2 from above, it is possible to restrict the upward movement of the battery units 70A-1 and 70A-2 relative to the slide plate 160. The front plate 180 and the middle plate 190 are examples of the "restraint member" of the present invention.

[0068] As shown in FIG. 13, the intermediate plate 190 is provided with two retaining portions 195A and 195B corresponding to the two storage battery units 70A-3 and 70A-4 located at the rear of the slide plate 160 (only one retaining portion 195B is shown in FIG. 13).

[0069] The two retaining portions 195A and 195B are configured to overlap the upper surfaces of the first mounting portions 73 of the storage battery units 70A-3 and 70A-4, respectively, and to retain the front ends of the storage battery units 70A-3 and 70A-4.

[0070] 10 and 13, the rear wall 163 of the slide plate 160 has three pressing portions 164A, 164B, and 164C at its upper end portion. The three pressing portions 164A, 164B, and 164C are bent forward.

[0071] The clamping portions 164A and 164B overlap the upper surface of the second mounting portion 79 of the upper plate 76 attached to the storage battery unit 70A-3, and the clamping portions 164B and 164C overlap the upper surface of the second mounting portion 79 of the upper plate 76 attached to the storage battery unit 70A-4.

[0072] In this way, by pressing down on the front and rear ends of the battery units 70A-3 and 70A-4 from above, it is possible to restrict the upward movement of the battery units 70A-3 and 70A-4 relative to the sliding plate 160. The intermediate plate 190 and the rear wall 163 of the sliding plate 160 are an example of the "restraining member" of the present invention.

[0073] 14 is a view of the sliding structure 150 as seen from below. A pair of rail members 169, each long in the front-to-rear direction (Z direction), is formed on the lower surface of the sliding plate 160. The rail members 169 are positioned inside the rollers 173, and the rollers 173 roll on the outside of the rail members 169.

[0074] <Harness and its following structure> 6, the power unit 50A and the storage battery unit 70A are electrically connected by a first harness P1 and a second harness P2. Specifically, the first harness P1 is drawn out from the storage battery unit 70A, and the second harness P2 is drawn out from the power unit 50A.

[0075] By connecting the two harnesses P1 and P2 with connectors, the power unit 50A and the storage battery unit 70A can be electrically connected.

[0076] In this embodiment, as described above, the connector 200 is disposed on the front surface of the storage battery unit 70A (see FIGS. 8 and 12), and the connector 200 can be connected and disconnected from the front surface of the storage battery unit 70A. 200A is a connector on the first harness P1 side, and 200B is a connector on the second harness P2 side.

[0077] If the connector 200 can be connected and disconnected on the front side of the storage battery unit 70A, the two storage battery units 70A-1 and 70A-2 mounted on the front side of the slide plate 160 can have their connectors 200 disconnected before being pulled out from the housing 100.

[0078] In contrast, the two storage battery units 70A-3 and 70A-4 mounted on the rear side are obstructed by the two storage battery units 70A-1 and 70A-2 mounted on the front side, and the connector 200 cannot be released until they are pulled out of the housing 100.

[0079] When the two rear storage battery units 70A-3 and 70A-4 are pulled out of the housing 100, the harness P2 is pulled along with them. Furthermore, when the units are stored in the housing 100, the harness P2 is pushed rearward. Therefore, during these operations, the second harness P2 may become entangled in surrounding components. To prevent this, a rail chain 210, which will be described below, is provided.

[0080] 15, the rail chain 210 is made up of a tune body 220, a first attachment part 230, and a second attachment part 240. The chain body 220 is made up of a plurality of rollers 225 connected in a chain shape, and has a cavity through which the second harness P2 passes.

[0081] The first attachment portion 230 is fixed via a bracket 235 to the outer surface of the side wall 161 of the slide plate 160, which is the movable side. Specifically, it is fixed to a position on the outer surface of the side wall 161 near the front end of the storage battery unit 70A-4. The second attachment portion 240 is fixed to the upper wall of the first frame 171 of the support frame 170, which is the supporting side. A second harness P2 is passed through the inside of the chain main body 220.

[0082] When the slide plate 160 is slid in the front-to-rear direction (Z direction) to insert or remove the storage battery units 70A-3 and 70A-4 from the housing 100, the chain body 220 moves forward or backward using the upper surface of the first frame 171 as a rail, as shown in Fig. 16. The action of the rail chain 210 causes the second harness P2 to move in the front-to-rear direction, following the movement of the storage battery units 70A-3 and 70A-4.

[0083] In this embodiment, two sets of harnesses P2 connected to two storage battery units 70A-3 and 70A-4 mounted on the rear of the sliding plate 160 are housed in one rail chain 210, so that the rail chain 210 is arranged on only one side of the sliding plate 160 (the front right side in FIG. 15). The rail chain 210 is not limited to being arranged on one side, but may also be arranged on both sides of the sliding plate 160.

[0084] This mechanism is also useful for the rear storage battery units 70A-3 and 70A-4, for which the connector 200 cannot be released before being pulled out.

[0085] Therefore, in this embodiment, the rail chain 210 is provided to follow the harness P2 only for the rear storage battery units 70A-3 and 70A-4, and not for the front storage battery units 70A-1 and 70A-2.

[0086] 4.Effects The storage battery unit 70A is heavy, weighing approximately 20 kg. When replacing the uninterruptible power supply 10, the heavy storage battery unit 70A can be easily removed by pulling it out of the housing 100, thereby reducing the burden on the worker.

[0087] Furthermore, when the second harness P2 is inserted into or removed from the housing 100, the second harness P2 is displaced to follow the battery units 70A-3 and 70A-4, thereby preventing the second harness P2 from getting tangled in surrounding components.

[0088] Furthermore, after being pulled out from the housing 100, when the connector 200 is released and the storage battery units 70A-3 and 70A-4 are removed, the position of the connector 200B connected to the tip of the second harness P2 can be restrained to a position around the first attachment portion 182 of the rail chain 210 (around part A in Figure 16).

[0089] This has the advantage that after the replaced storage battery units 70A-3 and 70-4 are mounted on the slide plate 160 and returned to the housing 100, the position of the connector 200B on the power unit side can be easily confirmed when connecting the connectors 200A and 200B.

[0090] Furthermore, the front plate 180, the middle plate 190, and the rear wall 163 of the sliding plate 160 restrict vertical movement of the storage battery units 70A-70C relative to the sliding plate 160, thereby preventing the storage battery units 70A-70C from moving up and down and interfering with surrounding components when transporting the uninterruptible power supply 10. Furthermore, because vertical movement is restricted when the storage battery units 70A-70C are pulled out of the housing 100, the pulling out can be performed stably.

[0091] <Other embodiments> The present invention is not limited to the embodiments described above and illustrated in the drawings, and the following embodiments, for example, are also included within the technical scope of the present invention.
