In the related art, large cables are needed to be used between the low-voltage cabinet 10 and the UPS cabinet module 20 and between the UPS cabinet module 20 and the UPS output cabinet module 30 and lifted to the wiring rack for connection, so that the construction is difficult and the cost is high. The present embodiment enables one side of the ups cabinet module 20 to be electrically connected to the bus 100 in the low-voltage cabinet 10, and the other side to be electrically connected to the bus 300 in the ups output cabinet module 30. In other words, the UPS cabinet module 20 is connected to the low-voltage cabinet 10 and the UPS output cabinet module 30 without using a large cable and a wiring rack, so that two opposite sides of the UPS cabinet module 20 are respectively and directly electrically connected to the bus bars 300 of the low-voltage cabinet 10 and the UPS output cabinet module 30, the wiring mode of the UPS cabinet module 20 is optimized, the UPS cabinet module 20 is directly connected to the bus bars 100 in the low-voltage cabinet 10, the UPS cabinet module 20 is directly connected to the bus bars 300 in the UPS output cabinet module 30, and standard samples are made and connected as required.

The manufacturer can directly standardize and prefabricate the customization, the whole transportation site is directly assembled, the site delivery time is reduced from 1 month to 1 day, and the labor, test cost and maintenance cost are reduced. In other words, the on-site delivery time and testing pressure are reduced, extra redundancy is eliminated, the cost is reduced, the reliability is improved, and the data center delivery tension and high availability requirements are met. Therefore, the power device 1 provided in this embodiment may also be referred to as a power device 1 suitable for rapid delivery, high efficiency and reliability of a data center.

Referring to fig. 1 again, in this embodiment, the ups cabinet module 20 includes a ups cabinet 23, a first bus 21, and a second bus 22, one end of the first bus 21 passes through a cabinet wall of the low-voltage cabinet 10 and is electrically connected to the bus 100 in the low-voltage cabinet 10, the other end passes through a cabinet wall of the ups cabinet 23 and is electrically connected to the input end 231 in the ups cabinet 23, one end of the second bus 22 passes through a cabinet wall of the ups cabinet 23 and is electrically connected to the output end 232 in the ups cabinet 23, and the other end passes through a cabinet wall of the ups output cabinet module 30 and is electrically connected to the bus 300 in the ups output cabinet module 30.

The uninterruptible power supply cabinet module 20 comprises an uninterruptible power supply cabinet 23, a first bus 21 and a second bus 22, wherein the first bus 21 is used for connecting the low-voltage cabinet 10 and the UPS cabinet module 20, and the second bus 22 is used for connecting the UPS cabinet module 20 and the UPS output cabinet module 30. Specifically, one end of the first bus bar 21 passes through the wall of the low-voltage cabinet 10 and is electrically connected to the bus bar 100 in the low-voltage cabinet 10, the other end passes through the wall of the uninterruptible power supply cabinet 23 and is electrically connected to the input end 231 in the uninterruptible power supply cabinet 23, one end of the second bus bar 22 passes through the wall of the uninterruptible power supply cabinet 23 and is electrically connected to the output end 232 in the uninterruptible power supply cabinet 23, and the other end passes through the wall of the uninterruptible power supply output cabinet module 30 and is electrically connected to the bus bar 300 in the uninterruptible power supply output cabinet module 30.

In summary, the UPS cabinet module 20, the low-voltage cabinet 10 and the UPS output cabinet module 30 all adopt a connection mode of a bus duct in the cabinet, and the first bus 21 and the second bus 22 directly penetrate through the cabinet wall to be connected, so that the length of an upper wiring frame and a lower wiring frame can be reduced, for example, the length of a cable in the related technology exceeds 4 meters, but in the embodiment, the length of the first bus 21 and the length of the second bus 22 can be reduced to 1 meter, so that the construction difficulty can be reduced, the cost can be reduced, and the electric charge cost caused by the cable loss can be reduced due to the reduction of the length.

Alternatively, the first busbar 21 is of unitary or split construction with the busbar 100 within the low-voltage cabinet 10. When the first bus bar 21 and the bus bar 100 in the low-voltage cabinet 10 are in an integrated structure, it can be understood that the first bus bar 21 is an extension part of the bus bar 100 in the low-voltage cabinet 10, and extends the bus bar 100 in the low-voltage cabinet 10, penetrates out of the cabinet wall of the low-voltage cabinet 10, penetrates into the cabinet wall of the UPS cabinet module 20, and is connected with the input end 231 of the UPS cabinet module 20.

Alternatively, the second bus 22 is of unitary or split construction with the bus 300 within the UPS output cabinet module 30. When the second bus 22 and the bus 300 in the UPS output cabinet module 30 are integrally formed, it is understood that the second bus 22 is an extension of the bus 300 in the UPS output cabinet module 30, and extends the bus 300 in the UPS output cabinet module 30, penetrates the cabinet wall of the UPS output cabinet module 20, and is connected to the output end 232 of the UPS output cabinet module 20.

In the present embodiment, the first bus bar 21 and the bus bar 100 in the low-voltage cabinet 10 can be provided on one side of the low-voltage cabinet 10. The second bus 22 and the bus 300 within the uninterruptible power supply output cabinet module 30 are located on the underside of the low voltage cabinet 10. For example, when the bus bar 100 in the low-voltage cabinet 10 is located at the upper side of the low-voltage cabinet 10, the first bus bar 21 is also located at the upper side in synchronization, and the second bus bar 22 is located at the lower side. When the bus bar 100 in the low-voltage cabinet 10 is located at the lower side of the low-voltage cabinet 10, the first bus bar 21 is also located at the lower side in synchronization, and the second bus bar 22 is located at the upper side.

In summary, the installation mode of the bus bar in the cabinet can be optimized in this embodiment, so that the first bus bar 21 at the input end 231 of the UPS cabinet module 20 and the second bus bar 22 at the output end 232 of the UPS cabinet module 20 are separately disposed on two opposite sides of the UPS cabinet module 20, which can avoid the two bus bars from crossing and reduce the construction difficulty. The low-voltage cabinet 10, the UPS input cabinet 24, the UPS25, the UPS output cabinet 31 and the bus of different delivery interfaces are effectively combined, so that the additional redundancy is eliminated, the cost is reduced, and the reliability is improved.

Or the second bus bar 22 may be threaded from within the cabinet into the base 40 and routed from within the base 40. Thus, the second bus 22 can be conveniently arranged and maintained in the later period, and the construction difficulty of the second bus 22 is reduced.

In the related art, the UPS input cabinet 24 and the UPS25 are respectively composed of two separate cabinet bodies, and the two cabinet bodies are electrically connected by a large cable. The UPS25 can convert direct current to alternating current or alternating current to direct current. In this embodiment, the UPS input cabinet 24 and the UPS25 may be integrated into one UPS cabinet 23, i.e., the UPS25 is disposed in the UPS input cabinet 24, so that the number of cabinets of the power apparatus 1 may be reduced, the length of the apparatus may be effectively reduced, thereby reducing the floor space and the cost, omitting cables, reducing the cost caused by cable and cable loss, and saving tens of thousands yuan. Taking 4 UPS25 with 500kVA as an example, the number of the cabinet bodies is reduced from 17 to 11, and the occupied area is reduced by 30 percent. The boring costs that can be reduced by a single power device 1 are more than hundreds of thousands. Alternatively, the UPS25 may have a capacity between 400kVA and 800 kVA.

The UPS25 is configured with two input switches corresponding to the first switch 241 and the second switch 242, and the UPS25 is also configured with an output switch corresponding to the third switch 243. The cost per switch is high and the switches between the UPS input cabinet 24 and the UPS25, and between the UPS25 and the UPS output cabinet 31, need to be connected by large cables.
