Description

The present invention relates to an uninterruptible power supply.

BACKGROUND ART Conventionally, a control panel including a casing that accommodates an electrical equipment unit is known (for example, see Patent Document 1).

The above-mentioned Patent Document 1 describes a control panel including a casing that accommodates an electrical equipment unit. The control panel described in Patent Document 1 includes a plurality of column parts extending in the vertical direction and a common plate arranged between the plurality of column parts and extending in the horizontal direction. The common plate is configured to be attachable to the column at desired intervals in the vertical direction. As a result, by changing the mounting position (height position) of the common plate relative to the column in accordance with electrical equipment units of different sizes, the members for mounting the electrical equipment units to the housing can be adjusted in size to each other. It is now possible to house electrical equipment units of different sizes in the housing without having to process the electrical equipment units according to the different electrical equipment units.

Although not described in Patent Document 1, the case described in Patent Document 1 may be used as a case of an uninterruptible power supply in which a plurality of types of electrical equipment units are housed in the case. It is possible to apply it. When the housing described in Patent Document 1 is applied to the housing of an uninterruptible power supply, multiple types of electrical equipment units housed in the housing may have multiple specifications having different output capacities. If each power supply includes electrical equipment units with different performance, even if the electrical equipment unit has a common performance that can be used with multiple specifications of uninterruptible power supplies with different output capacities, The mounting position with respect to the housing may be different for each uninterruptible power supply device having a plurality of specifications having mutually different output capacities. That is, the arrangement of the plurality of types of electrical equipment units with respect to each housing is likely to be different for each uninterruptible power supply device having a plurality of specifications having mutually different output capacities. In this case, due to the difference in the arrangement of the electrical equipment unit with respect to the housing, the wiring route of the equipment in the uninterruptible power supply, the length of the wiring, wind flow, energy loss, etc. due to the change in the wiring route will also change. Put it away. For this reason, various performances of the uninterruptible power supply, such as noise resistance, cooling performance, noise, and ease of maintenance, change. For example, the noise resistance performance of an uninterruptible power supply is affected by the arrangement of equipment, the wiring route, the length of the wiring due to a change in the wiring route, and the like. Furthermore, the cooling performance of an uninterruptible power supply is affected by wind flow, energy loss, and the like. Further, noise in an uninterruptible power supply is affected by the arrangement of devices (mainly fans). Furthermore, the maintainability of the uninterruptible power supply is affected by the arrangement of the equipment. For this reason, if multiple types of electrical equipment units are arranged differently relative to the housing, various performance problems in the uninterruptible power supply may occur for all the electrical equipment units whose arrangement relative to the housing is different. It is necessary to conduct an evaluation test to evaluate whether or not this is occurring. In this case, the total number of evaluation tests performed on uninterruptible power supplies of a plurality of specifications becomes relatively large. Therefore, a configuration is desired that can reduce the total number of evaluation tests performed on uninterruptible power supplies of a plurality of specifications.

This invention was made to solve the above problems, and one purpose of the invention is to reduce the total number of evaluation tests performed on uninterruptible power supplies of multiple specifications. The object of the present invention is to provide an uninterruptible power supply device that can perform

In order to achieve the above object, an uninterruptible power supply according to one aspect of the present invention is an uninterruptible power supply that supplies power for a certain period of time during a power outage, the uninterruptible power supply being supplied from an AC power source external to the uninterruptible power supply.

Thereby, the arrangement of a plurality of types of electrical equipment units with respect to each housing can be made common to a plurality of uninterruptible power supply devices having different specifications and different output capacities. In other words, even if multiple types of electrical equipment units housed in a housing include electrical equipment units that have different performance for uninterruptible power supplies of multiple specifications with different output capacities, Electrical equipment units with common performance that can be compatible with multiple specifications of uninterruptible power supplies with different output capacities must be mounted to the chassis for each of the multiple specifications of uninterruptible power supplies with different output capacities. The positions will be equal. For example, an evaluation test of an electrical equipment unit with a common performance that can be applied to uninterruptible power supplies of multiple specifications with different output capacities is performed on uninterruptible power supplies of multiple specifications with different output capacities. It is only necessary to perform this once for only one of them. As a result, it is possible to reduce the number of electrical equipment units that need to be evaluated for uninterruptible power supplies with multiple specifications by limiting variations in the arrangement of electrical equipment units with respect to the housing. . As a result, the total number of evaluation tests performed on uninterruptible power supplies of a plurality of specifications can be reduced.

With this configuration, the electrical equipment units accommodated in the capacity-based partitioned areas have different performances for each uninterruptible power supply with multiple specifications having different output capacities, so that the electrical equipment units accommodated in the capacity-based partitioned areas have different performances. Although the equipment unit evaluation test needs to be performed each time for each uninterruptible power supply with multiple specifications that have different output capacities, the electrical equipment units housed in the common partition area have different output capacities. Since it has a common performance that can be applied to uninterruptible power supplies of multiple specifications, the evaluation test of electrical equipment units housed in a common partition area is applicable to uninterruptible power supplies of multiple specifications that have different output capacities. It is only necessary to perform this once for only one of the following.

In this case, preferably, the divided area in which the power conversion units are accommodated is a divided area by capacity, and the divided area in which electric equipment units of types other than the power conversion units are accommodated is a common divided area. With this configuration, the power conversion units housed in the capacity-specific partitioned areas have different performance for each uninterruptible power supply with multiple specifications having different output capacities, so the evaluation test of the power conversion units can be Although it is necessary to do this each time for each uninterruptible power supply with multiple specifications having different output capacities, electrical equipment units of types other than power conversion units housed in the common partition area have multiple specifications with different output capacities. The evaluation test for electrical equipment units other than power conversion units has a common performance that can be applied to uninterruptible power supplies with different specifications. It is only necessary to perform this once for only one of them. In other words, the power conversion unit is the only electrical equipment unit that needs to be evaluated each time for each of the uninterruptible power supplies having a plurality of specifications having different output capacities. As a result, the total number of evaluation tests performed on uninterruptible power supplies of a plurality of specifications can be significantly reduced.

In the uninterruptible power supply according to the first aspect, preferably, the power conversion unit includes a common component having a common performance that can be applied to uninterruptible power supplies of a plurality of specifications having mutually different output capacities, and a mutually different For each uninterruptible power supply having a plurality of specifications having an output capacity, a capacity-specific component having a different performance for each output capacity is included, and a common component arrangement part where common components are arranged, and a common component arrangement part where the capacity-specific components are arranged. and a capacity-based component arrangement section to be arranged. With this configuration, the capacity-specific components arranged in the capacity-specific component arrangement section have different performance for each uninterruptible power supply with a plurality of specifications having different output capacities, so that the capacity-specific components arranged in the capacity-specific component arrangement section are Although evaluation tests for components by capacity must be performed each time for each uninterruptible power supply with multiple specifications that have different output capacities, common components placed in the common component placement area have different output capacities. It has a common performance that can be applied to uninterruptible power supplies of multiple specifications with different output capacities. It is only necessary to perform this once for any one of the power supply devices. As a result, the total number of evaluation tests performed on uninterruptible power supplies of multiple specifications can be reliably reduced.

With this configuration, in the capacity-separated area where cut-off units of different sizes are accommodated depending on the output capacity of the uninterruptible power supply, a cut-off unit corresponding to an uninterruptible power supply having a relatively small output capacity is installed. When the battery is housed, the space where the cutoff unit is not placed (empty space) can be used as a space for housing the battery. As a result, the number of battery casings provided for accommodating the battery other than the casing of the uninterruptible power supply can be reduced.

(Effects of the first embodiment)
In the first embodiment, the following effects can be obtained.

In the first embodiment, as described above, the casing 20 includes a plurality of partitioned areas 21 each having a certain size and partitioned for each type of a plurality of electrical equipment units 10. Each of the plurality of divided areas 21 accommodates an electrical equipment unit 10 having performance corresponding to any one of the uninterruptible power supplies 100 of a plurality of specifications having mutually different output capacities. Thereby, the rough arrangement of the plurality of types of electrical equipment units 10 with respect to each housing 20 can be made common to the uninterruptible power supply devices 100 of a plurality of specifications having mutually different output capacities. That is, there is a case where the plurality of types of electrical equipment units 10 housed in the casing 20 include electrical equipment units 10 having different performances for each uninterruptible power supply 100 of a plurality of specifications having mutually different output capacities. However, an electrical equipment unit 10 having a common performance that can be applied to uninterruptible power supplies 100 of a plurality of specifications having mutually different output capacities can be used for uninterruptible power supplies 100 of a plurality of specifications having mutually different output capacities. The mounting position with respect to the housing 20 is the same for each case. For example, an evaluation test of an electrical equipment unit 10 having a common performance that can be applied to uninterruptible power supplies 100 of a plurality of specifications having different output capacities is performed on an uninterruptible power supply having a plurality of specifications having different output capacities. It is only necessary to perform this once for any one of the devices 100. This reduces the number of electrical equipment units 10 that need to be evaluated for uninterruptible power supplies 100 with multiple specifications by limiting variations in the arrangement of electrical equipment units 10 with respect to the housing 20. can do. As a result, the total number of evaluation tests performed on uninterruptible power supplies 100 of a plurality of specifications can be reduced. Note that when using electrical equipment units 10 having common performance for uninterruptible power supplies 100 with different specifications, the electrical equipment unit 10 having performance corresponding to the uninterruptible power supplies 100 with specifications having a large output capacity is selected. be done. For example, if a common electrical equipment unit 10 is used for an uninterruptible power supply 100 with an output capacity of 3-phase 10kVA and an uninterruptible power supply 100 with an output capacity of 3-phase 20kVA, the output capacity is 3-phase 20kVA. An electrical equipment unit 10 having performance corresponding to the uninterruptible power supply 100 having the specifications is selected. Furthermore, when using electrical equipment units 10 that have common performance for uninterruptible power supplies 100 with different specifications, the evaluation test of the electrical equipment unit 10 corresponds to the uninterruptible power supply 100 with the largest specification of the output capacity. The evaluation test is performed only on the electrical equipment unit 10 having the performance. For example, if a common electrical equipment unit 10 is used for an uninterruptible power supply 100 with an output capacity of 3-phase 10kVA and an uninterruptible power supply 100 with an output capacity of 3-phase 20kVA, the output capacity is 3-phase 20kVA. The evaluation test is performed only on the electrical equipment unit 10 having the performance corresponding to the uninterruptible power supply 100 having the specifications.

As a result, the electrical equipment units 10 accommodated in the capacity-based partition area 21b have different performances for the uninterruptible power supplies 100 of a plurality of specifications having mutually different output capacities. Although the evaluation test of the equipment unit 10 needs to be performed each time for each uninterruptible power supply 100 of a plurality of specifications having different output capacities, the electrical equipment units 10 housed in the common partition area 21a are Since it has a common performance that can be applied to uninterruptible power supplies 100 of a plurality of specifications having different output capacities, the evaluation tests of the electrical equipment units 10 housed in the common partition area 21a have mutually different output capacities. It is only necessary to perform the process once for any one of the uninterruptible power supplies 100 having a plurality of specifications. As a result, the total number of evaluation tests performed on uninterruptible power supplies 100 of a plurality of specifications can be reliably reduced.

Further, in the first embodiment, as described above, when comparing the uninterruptible power supply 100 with an output capacity of 3-phase 10 kVA and the uninterruptible power supply 100 with an output capacity of 3-phase 20 kVA, the power The partitioned area 21 in which the conversion units 11 are accommodated is a capacity-based partitioned area 21b, and the partitioned area 21 in which electrical equipment units 10 of types other than the power conversion unit 11 are accommodated is a common partitioned area 21a. As a result, when comparing an uninterruptible power supply 100 with an output capacity of 3-phase 10 kVA and an uninterruptible power supply 100 with an output capacity of 3-phase 20 kVA, the power conversion accommodated in the capacity-specific division area 21b Since the unit 11 has different performance for each uninterruptible power supply 100 of a plurality of specifications having mutually different output capacities, the evaluation test of the power conversion unit 11 is performed for the uninterruptible power supplies 100 of a plurality of specifications having mutually different output capacities. Although it is necessary to perform this process every time for each of Therefore, the evaluation test for electrical equipment units 10 of types other than the power conversion unit 11 is performed on only one of the uninterruptible power supplies 100 of a plurality of specifications having different output capacities. You only need to do it once. In other words, when comparing an uninterruptible power supply 100 with an output capacity of 3-phase 10 kVA and an uninterruptible power supply 100 with an output capacity of 3-phase 20 kVA, the uninterruptible power supply 100 has multiple specifications with different output capacities. The power conversion unit 11 is the only electrical equipment unit 10 that needs to undergo an evaluation test for each power supply device 100 each time. As a result, the total number of evaluation tests performed on uninterruptible power supplies 100 of a plurality of specifications can be significantly reduced.

The power conversion unit 11 includes a common component arrangement section 11f in which the common components 11d are arranged, and a capacity-based component arrangement section 11g in which the capacity-based components 11e are arranged. As a result, the capacity-specific components 11e arranged in the capacity-specific component arrangement section 11g have different performance for each uninterruptible power supply 100 of a plurality of specifications having different output capacities, so they are arranged in the capacity-specific component arrangement section 11g. Although the capacity-specific components 11e need to be installed every time for each of the uninterruptible power supplies 100 of a plurality of specifications having different output capacities, the common components 11d arranged in the common component placement section 11f have different output capacities. Since it has a common performance that can be applied to uninterruptible power supplies 100 of multiple specifications having different capacities, the evaluation test of the common component 11d placed in the common component placement section 11f is performed using multiple uninterruptible power supplies 100 having different output capacities. It is only necessary to perform the process once for any one of the uninterruptible power supplies 100 according to the specifications. As a result, the total number of evaluation tests performed on uninterruptible power supplies 100 of a plurality of specifications can be reliably reduced.

Further, in the first embodiment, as described above, the plurality of partitioned areas 21 have different performance for each output capacity for each of the uninterruptible power supplies 100 of a plurality of specifications having different output capacities, and also for each of the uninterruptible power supplies 100 with different output capacities. It includes divided areas 21b classified by capacity in which electrical equipment units 10 having different sizes are accommodated. The capacity-specific partitioned area 21b has mounting holes 22 for attaching the electrical equipment units 10 to the housing 20 so as to correspond to electrical equipment units 10 having mutually different performances and mutually different sizes. Multiple formations. As a result, the electrical equipment units 10 that are housed in the compartment area 21b according to capacity and have different sizes from each other can be attached to the housing by the mounting holes 22 that are formed in plurality so as to correspond to the electrical equipment units 10 that have different sizes from each other. 20 can be easily attached.

A plurality of partitioned areas 21 for accommodating each of the power conversion unit 11, reactor unit 12, control unit 15, cutoff unit 16, and external connection unit 17 are arranged vertically in the housing 20. ing. As a result, a plurality of divided areas 21 for accommodating each of the power conversion unit 11, the reactor unit 12, the control unit 15, the cutoff unit 16, and the external connection unit 17 are arranged vertically in the housing 20. The total number of evaluation tests performed on the uninterruptible power supply 100 of a plurality of specifications can be reduced.

Further, in the first embodiment, as described above, the plurality of electrical equipment units 10 are used to interrupt the electric circuit in the uninterruptible power supply 100, and the size is determined according to the output capacity of the uninterruptible power supply 100. It further includes different blocking units 16. Further, the plurality of partitioned areas 21 include a capacity-based partitioned area 21b in which electrical equipment units 10 having different performance for each output capacity are accommodated for each of the uninterruptible power supplies 100 of a plurality of specifications having different output capacities. including. The capacity-based divided area 21b in which the cutoff unit 16 corresponding to the uninterruptible power supply 100 having the second output capacity smaller than the first output capacity is accommodated is a space in which the cutoff unit 16 is not arranged.

As a result, in the capacity divided area 21b that accommodates the cutoff units 16 having different sizes depending on the output capacity of the uninterruptible power supply 100, the cutoff unit 16 corresponding to the uninterruptible power supply 100 having a relatively small output capacity is When the battery 30 is accommodated, the space where the cutoff unit 16 is not placed (empty space) can be used as a space for accommodating the battery 30. As a result, the number of battery casings provided for accommodating the battery 30 other than the casing 20 of the uninterruptible power supply 100 can be reduced.

Further, in the first embodiment, as described above, the plurality of electrical equipment units 10 further include the interrupting unit 16 used to interrupt the electric circuit in the uninterruptible power supply 100. Moreover, the interrupting unit 16 includes a plurality of circuit breakers 16a arranged adjacent to each other.
