[0032] The embodiment of the present application discloses a high-voltage AC power distribution integrated system of a commercial and industrial energy storage cabinet. Referring to Figure 1 andFigure 2 The high-voltage alternating current power distribution integrated system of the industrial and commercial energy storage cabinet comprises a shell 1, a direct current module 2 and an alternating current module 3 are arranged in the shell 1; the direct current module 2 comprises a direct current protection module arranged in the shell 1, and a power line bundle quick plug assembly 4 is arranged at the input and output ends of the direct current protection module; the alternating current module 3 comprises an alternating current protection module arranged in the shell 1, and a terminal connection row 5 is arranged at the input and output ends of the alternating current protection module. That is, the direct current module 2 and the alternating current module 3 are integrated in the shell 1, so that the user and the maintenance personnel only need to connect the direct current input and output through the power line bundle quick plug assembly 4 arranged at the end of the shell 1 with the input and output of the direct current protection module to complete the direct current side connection; similarly, the alternating current side is connected through the terminal connection row 5, and the personnel do not need to separately wire each component of the alternating current configuration system, thereby ensuring the convenience of wiring. In addition, the direct current and the alternating current are distinguished by the power line bundle quick plug assembly 4 and the terminal connection row 5, which further ensures that the personnel miswiring situation does not occur.

[0033] With reference to Figure 3 and Figure 5 The power line bundle quick plug assembly 4 comprises a female seat 41 connected with the direct current protection module and a plug-in 42 buckled in the female seat 41, and a locking mechanism 43 is arranged between the plug-in 42 and the female seat 41, wherein the locking mechanism 43 can adopt an elastic locking piece or the like locking structure. That is, only the plug-in 42 is inserted into the female seat 41, and the locking is completed through the locking mechanism 43, so as to complete the wiring and facilitate the personnel wiring.

[0034] With reference to Figure 2 and Figure 3 The direct current protection module comprises a fuse 21, a pre-charging relay 22, a relay 23 and a direct current air switch 24 arranged in sequence. That is, the series connection of the fuse 21, the pre-charging relay 22, the relay 23 and the direct current air switch 24 is arranged to ensure the safety and reliability of the direct current module 2. At the same time, a control knob 25 for controlling the direct current air switch 24 is arranged on the shell 1 to realize the effect of manually adjusting the air switch reset or short circuit, thereby facilitating the personnel operation.

[0037] The implementation principle of the high-voltage AC power distribution integrated system of the commercial and industrial energy storage cabinet according to the embodiment of the application is that the integrated system can be matched with the AC / DC side of the outdoor cabinet as a standard part. Meanwhile, the AC circuit breaker added inside the AC side increases the safety and reliability of the product in use (the AC line can be turned on and off at any time), and the layout of the wiring terminal of the product is in a straight-in line mode, which facilitates the wire harness wiring operation. On the other hand, for the production end, the production efficiency is improved, and the misoperation of the workers during the production process is avoided, such as wiring.
