Electrical cabinets are widely used in the chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry, etc.

[0003] When the electrical cabinet is used in cold winter areas, condensation problems may occur. In warm climates, the water vapor in the cabinet evaporates faster than in cold weather. When there is moisture in the cabinet, it evaporates first and then condenses. Only when evaporation is not timely will it condense into dew drops. However, in winter, this moisture will be directly frozen on the components of the substation cabinet, and will turn into ice or frost over time.

[0004] In the related art, when the temperature of the components of the electrical cabinet changes, the ice on the surface of the components will directly turn into water when the temperature of the components rises, and then it will be frozen into frost again when the temperature drops, and the cycle will repeat. However, most of the existing electrical cabinets are not convenient for de-icing during use. When the components are operated in such an environment for a long time, it will cause great hidden dangers, such as discharge, short circuit, insulation breakdown, explosion and fire.
