[0024] Please see Figure 1 , Figure 1 This is a three-dimensional structural diagram of an online maintainable power module 100 provided in an embodiment of the present invention. The online maintainable power module 100 is a power system with a modular structural design, used for power supply and distribution to large data centers, and can be applied in open outdoor or enclosed indoor environments.
[0025] Please refer to the following: Figure 1 and Figure 2 The online maintainable power module 100 includes a rack 1 with a receiving space, several UPS power modules 2, several UPS switch cabinets 6, a first busbar 3, a second busbar 4, and a shorting N-bar 5, wherein the UPS power modules 2, the UPS switch cabinets 6, the first busbar 3, the second busbar 4, and the shorting N-bar 5 are all housed in the receiving space.
[0026] The first busbar 3 is electrically connected to the UPS power module 2 via the shorting N-bar 5. The shorting N-bar 5 is used to balance the current of each phase load and reduce the current on the neutral line, thereby improving the efficiency and safety of the power system. Each UPS switch cabinet 6 corresponds to two UPS power modules 2. The UPS switch cabinet 6 and the UPS power module 2 are electrically connected via the second busbar 4. The UPS switch cabinet 6 can provide isolation function, allowing maintenance or replacement of specific components without disconnecting the system power.
[0027] Please refer to the following: Figure 2 and Figure 3 , Figure 2 for Figure 1 The diagram shown is a three-dimensional structural representation of the UPS power module assembled with the rack. Figure 3 for Figure 1 The diagram shows a three-dimensional structure of the UPS power module. The UPS power module 2 has multiple hot-swappable interfaces 21 on its top and sides. The first busbar 3 is horizontally positioned above the UPS power module 2, and the second busbar 4 is positioned on the side of the UPS power module 2. The first busbar 3 and the second busbar 4 are detachably connected to the hot-swappable interfaces 21. The first busbar 3 is electrically connected to the hot-swappable interface 21 via the shorting N-bar 5, and one end of the second busbar 4 is directly electrically connected to the hot-swappable interface 21.
[0028] The hot plug interface 21 is arranged in cooperation with the ports of the short-circuit N busbar 5 and the second busbar 4. In order to realize stable connection, in the embodiment, after the hot plug interface 21 is clamped and connected with the short-circuit N busbar 5 and the port of the second busbar 4, a bolt is further used to fix the two interfaces. When the UPS power module 2 needs to be maintained due to failure, the corresponding bolt is only needed to be removed, so that the electrical connection between the UPS power module 2 and other components is disconnected, and online maintenance can be quickly performed.
[0029] The rack 1 comprises a clamping member 13 arranged corresponding to the position of the second busbar 4. The clamping member 13 comprises a first member and a second member which are mirror-symmetrically arranged and have a comb-shaped structure, and the first member and the second member are cooperated to allow different cables to be arranged in different tooth grooves. The clamping member 13 clamps and fixes the second busbar 4 to the rack 1, so as to facilitate arrangement of the cables. It can be understood that in the embodiment, the number of the clamping members 13 can be two, and in other embodiments, the number of the clamping members 13 can be one or more, which is determined according to the actual assembly process.
