[0031] Embodiment 2

[0032] Based on Example 1, this embodiment includes: a dehumidification mechanism 13 is arranged on the top of the low-voltage distribution cabinet 8, the dehumidification mechanism 13 includes a shell 130 fixedly installed on the top of the low-voltage distribution cabinet 8, a high-density mesh panel 131 is fixedly installed on the top and bottom of the shell 130, the interior of the shell 130 is filled with a desiccant 132, and a through groove 133 is opened on the inner top wall of the low-voltage distribution cabinet 8, and a plurality of fans 134 are fixedly installed on both sides of the inner wall of the through groove 133 through a fixing plate.

[0033] The technical solution provided in this embodiment is: by starting the fan 134, the fan 134 draws the outside air into the low-voltage distribution cabinet 8 through the through groove 133. While the air passes through the desiccant 132, the desiccant 132 can adsorb the moisture in the air, which is used to dry the air, and the dried air enters the low-voltage distribution cabinet 8, thereby achieving the purpose of dehumidifying the low-voltage distribution cabinet 8 and effectively preventing the problem of corrosion and damage to electrical equipment caused by long-term intrusion of moisture.

By setting the damper 14 and the second spring 16, the buffering function of the low-voltage distribution cabinet 8 is achieved. When a heavy object falls on the surface of the low-voltage distribution cabinet 8, the impact force will cause the damper 14 to contract, thereby compressing the second spring 16, and then offsetting the impact force, thereby protecting the low-voltage distribution cabinet 8.

[0036] Furthermore, a mounting cover 17 is fixedly installed on the inner top wall of the low-voltage distribution cabinet 8, and LED lamp tubes 18 are commonly arranged on both sides of the inner wall of the mounting cover 17.

[0037] Specifically, the LED lamp tube 18 is used to provide auxiliary lighting for the staff when they are repairing the low-voltage distribution cabinet 8 when the lighting conditions are poor, so as to facilitate viewing and maintenance. By holding the handle 20 and pulling the door body 19, the door body 19 is opened, which is convenient for the staff to repair the low-voltage distribution cabinet 8. The working status of the low-voltage distribution cabinet 8 can be intuitively seen through the observation window 21, so as to facilitate timely detection of problems.
