At present, the dehumidification in the switch cabinet or electric room of the power system is generally carried out by automatic heating or air conditioning condensation. The heating and dehumidification mainly uses the heating plate to heat the air in the cabinet, and then uses the fan to circulate the hot air in the cabinet. This method generally has a large power, and the moisture in the air evaporates and dries in a short time in the cabinet. Once the temperature drops, it will condense into condensation and attach to the surface of the electrical components in the cabinet; For cabinet equipment, there are serious condensation and mildew phenomena in the terminal blocks, wires, and inner walls of the cabinet, which seriously affect the safe operation of cabinet equipment.
