[0016] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0018] In one embodiment of the utility model, each bidirectional source-load power supply module 20 has 6 output terminals, which are 3 L-phase output terminals and 3 N-phase output terminals. The output terminals of the bidirectional source-load power supply module 20 are refluxed in the splitter 100, and the splitter 100 has N*6 inputs and 1 output. A single splitter 100) can gather up to 12 output lines, which can meet the work of up to 12 bidirectional source-load power supply modules 20, and is suitable for various cabinets of 15U-42U. The splitter 100) is used as a busbar, making the wiring of the whole machine simple and clear. When the user connects multiple machines in parallel or tests a single machine, it can be connected to the output of the splitter 100 and the corresponding bidirectional source-load power supply module 20 is turned on.

[0019] See also Figure 1 and Figure 2 As shown, in one embodiment of the utility model, the bidirectional source-loaded power parallel cabinet also includes a first bus 200, a second bus 410 and a third bus 420, which are used by the user to test in a special mode when the L-phase output terminal and the N-phase output terminal are connected in parallel.

[0020] In one embodiment of the utility model, a first busbar 200 is provided on each bidirectional source-load power supply module 20 for performing a single-machine test in a special mode. Two first busbars 200 are provided on each bidirectional source-load power supply module 20, respectively connected to the L-phase output terminal and the N-phase output terminal of the bidirectional source-load power supply module 20. When the user tests, two lines are connected from the two first busbars 200 respectively to perform a single-machine test in a special mode.

[0021] In one embodiment of the utility model, when the user needs to perform a multi-machine parallel test, after the output terminals of each bidirectional source-load power supply module 20 are converged on the splitter 100, the second bus 410 is connected to the L-phase output terminal of the splitter 100, and the third bus 420 is connected to the N-phase output terminal of the splitter 100, and then two lines are respectively output from the second bus 410 and the third bus 420 to perform a multi-machine parallel test in a special mode. If several bidirectional source-load power supply modules 20 are required to be tested in parallel, several bidirectional source-load power supply modules 20 can be turned on. Undoubtedly, a single machine test in a special mode can also be performed through the second bus 410 and the third bus 420.

The splitter 100 sets the L-phase output terminal and the N-phase output terminal of the convergence with a height difference, and fixes the L-phase output terminal and the N-phase output terminal of the convergence on the cabinet 10 respectively through the terminal fixing part 300. The test error caused by the output terminal being too close is avoided, and the wiring process is also made more convenient, which greatly improves the safety and operation convenience of the paralleling cabinet.

[0023] In one embodiment of the utility model, the bidirectional source-loaded power supply cabinet includes a copper bar spacer 500, and the number of the copper bar spacer 500 is multiple. The copper bar spacer 500 is arranged between the splitter 100 and the three-phase input port of the cabinet 10. And, among the three-phase input ports L1, L2, and L3 of the cabinet 10, a copper bar spacer 500 is arranged between adjacent phase input ports. Among them, the three-phase input port is fixed to the cabinet 10 through a copper bar through-wall plastic part 600, which prevents contact between the output terminals caused by deformation of the cable due to external force after the user connects the wires, thereby improving the safety of the cabinet.
