[0003] The heat dissipation holes of the existing distribution cabinet are at the top. Although opening the heat dissipation holes at the top can greatly suppress the temperature rise inside the distribution cabinet, the existing opening method is too simple and rough, which will greatly reduce the protection level of the distribution cabinet.

[0004] Therefore, we proposed a top-protected high-voltage frequency conversion distribution cabinet to solve the above problems. Utility Model Content

[0008] With the use of the limiting mechanism, the protective cover can be stably installed on the top of the socket block, and the heat dissipation port on the top of the distribution cabinet body can be protected under physical action, thereby increasing the service life of the distribution cabinet body during use.

[0012] Under the protective effect of the protective pad, the hands of the staff and the outer side wall of the limit rod can be effectively protected.

[0013] As a preferred embodiment of the above technical solution, a limiting protrusion is inserted into the outer wall of the bottom end of the plug board, and the bottom end of the limiting protrusion is installed at the bottom end of the inner wall of the Y-shaped groove.

[0014] The special "mushroom" shape of the limiting protrusion and the use of elastic materials such as rubber at the top of the limiting protrusion further increase the stability of the connection between the plug board and the Y-slot.
