Description

technical field [0001] The invention relates to dehumidification equipment in the electric power industry, in particular to a drainage type electric cabinet dehumidifier. Background technique [0002] At present, the heating dehumidifier used in the power industry mainly reduces the relative humidity by increasing the air temperature in the cabinet. Since the hot air has a higher saturated water vapor partial pressure, the relative humidity is reduced, but the moisture content of the air is not. The change also exists in the cabinet. When the heating stops or the ambient temperature drops a lot, the water vapor in the air reaches saturation, forming condensation, which condenses on the surface of the equipment. Therefore, in actual operation, it is often found that serious condensation still occurs in the cabinet where the heating dehumidifier is installed, which endangers the normal operation of electrical equipment. Contents of the invention [0003] The technical pr...
