Dehumidification device for electrical cabinet

Abstract

The invention discloses a dehumidification device for an electrical cabinet. The dehumidification device comprises a water condenser and a drainer, wherein the water condenser is arranged in the electrical cabinet and used for condensing vapor in the electrical cabinet, and then liquid water is formed; the drainer is connected with the water condenser and used for draining the liquid water condensed through the water condenser out of the electrical cabinet. According to the dehumidification device, the water condenser is arranged in the electrical cabinet, the water condenser is used for independently condensing the vapor in the electrical cabinet, the liquid water is formed and drained out of the electrical cabinet through the drainer, the air humidity in the electrical cabinet is effectively reduced, and the water content in air in the electrical cabinet is obviously smaller than the saturation humidity ratio of the electrical cabinet, so that the situation that the vapor in air is condensed on the surface of equipment due to sharp drop of environment temperature is avoided, through the dehumidification device for the electrical cabinet, the air humidity in the electrical cabinet can be effectively reduced, the situation that water is condensed on the surface of the equipment due to drop of the external environment temperature, and safety operation of the electrical equipment is damaged is avoided, and the reliability of the electrical equipment is improved.

Description

technical field [0001] The invention relates to the technical field of electrical equipment design, in particular to an electrical box dehumidification device. Background technique [0002] If the ambient temperature and humidity are too high, the temperature rise of electrical equipment will also increase, which will easily lead to accelerated insulation aging, and in severe cases, insulation will be burned. However, if the air humidity is too high, moisture will condense on the surface of the equipment, causing mold to grow faster, reducing electrical insulation strength, and metal corrosion. Acceleration will cause the contact surface to dehumidify and the contact resistance will increase, so it is necessary to dehumidify the electrical equipment. [0003] In the prior art, a heating type dehumidifier is used to realize the dehumidification operation in the electrical box by increasing the temperature in the electrical box. However, due to the high temperature, the moist...
