Abstract

The application discloses a dehumidification device for a switch cabinet, which comprises a casing, a fan, a refrigerating component and a condensed water conduit, wherein an air inlet, an air outlet and a condensed water outlet are formed in the casing; the refrigerating component is arranged on an air duct located between the air inlet and the air outlet; one end of the condensed water conduit is connected with the condensed water outlet, and the other end is located outside the switch cabinet. According to the application, water vapor contained in the humid air is condensed to water through the refrigerating component, the condensed water is further discharged out of the switch cabinet through the condensed water conduit, so that the phenomenon of water circulation of evaporation and condensation in the prior art is prevented, water in the switch cabinet is removed completely, the air humidity in the switch cabinet is reduced, and the problem in the prior art is solved.

Description

technical field [0001] The present application relates to the technical field of detection, in particular to a switch cabinet dehumidification device. Background technique [0002] During the use of electrical equipment such as switch cabinets, due to the high ambient humidity, water vapor in the air encounters electrical equipment with a lower temperature, and it is easy to form water droplets, which adhere to the surface of the insulating material of the electrical equipment and reduce the resistance of the insulating material. , And then reduce the insulation performance of electrical equipment, cause the switch trip setting to damage the electrical equipment, not only increase the workload of maintenance personnel, but also affect the safe and reliable operation of the system where the electrical equipment is located. Therefore, it is necessary to dehumidify electrical equipment. [0003] In the prior art, a heating plate is generally used to dehumidify the switchgear, ...
