[0041] Working principle and process of a modular sheet metal electrical cabinet:

[0042] Once the electrical cabinet is installed and in normal working order, the cooling fan 52 installed in the fan hole 12 on the right side of the cabinet shell 1 can start working. It works by using the circular opening in the heat dissipation cover 51 and the ventilation hole 11 on the left side of the electrical cabinet to dissipate heat. If the cooling fan malfunctions, the staff can open the heat dissipation cover 51 through the handle installed on the heat dissipation cover 51 to replace or repair the cooling fan 51. The right rain cover 22 installed on the surface of the heat dissipation cover 51 and the left rain cover 21 installed on the surface of the ventilation hole 11 are used to prevent rainwater from entering the electrical cabinet during rainfall.

[0043] When the electrical cabinet is exposed to rainfall, rainwater falls onto the top seat 42 of the cabinet and flows through the herringbone structure to the inclined slider 43. The rainwater flows into the drainage trough 45 through the structure of the inclined slider 43, which is higher at the front and lower at the back. After flowing into the water pipe 46, it is discharged to prevent water accumulation. The filter screen 44 installed on the outer shell 41 can prevent foreign objects from clogging the outlet of the drainage trough 45. The filter screen 44 is also convenient for staff to clean and replace by hanging it on the outer shell 41.

[0044] When staff need to inspect the electrical cabinet, when the electrical cabinet door 3 is opened by the handle, the push-button switch 61 will spring open because it is not under the pressure of the electrical cabinet door 3, and the light 6 will turn on, illuminating the inside of the electrical cabinet. The drawer 71 inside the drying box 7 can be pulled out to replace the desiccant, or the tools stored in the storage box 8 can be replaced.
