Abstract

The invention discloses a dehumidification device for a switch cabinet. The dehumidification device comprises a dehumidification box arranged in parallel with a switch cabinet body, wherein a one-wayair circulation device connected with the dehumidification box is arranged at the upper part in the switch cabinet body; the lower part of the side surface of the dehumidification box is provided witha backflow air jet hole communicated with the interior of the switch cabinet body. The one-way air circulation device comprises a hydraulic cylinder and an expansion air bag, the hydraulic cylinder is fixed in the center of the inner top surface of the switch cabinet body, a lifting rod is arranged at the output end of the hydraulic cylinder, the lower end of the lifting rod is connected with a lifting plate, and the top part of the expansion air bag is hermetically butted to the bottom surface of the lifting plate. By arranging the one-way air circulation device, the dehumidification deviceavoids the sequence of air circulation from being influenced by air turbulence possibly caused by a fan adopted during conventional dehumidification, ensures orderly entering of air in the switch cabinet body, avoids flying dust static electricity possibly caused when the fan works, and prevents potential safety hazards possibly caused by concurrence of a high-temperature state and a flying dust state in the switch cabinet, and therefore the safety of the switch cabinet is guaranteed in the dehumidification process.

Description

technical field

[0001] The invention relates to a switch cabinet dehumidification technology, in particular to a dehumidification device for a switch cabinet. Background technique

[0002] The switch cabinet is a kind of electrical equipment. The outside line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs, such as instruments, automatic control, motor magnetic switches, various AC contactors, etc. For some switch cabinets, if the moisture can dissipate in a short period of time, dehumidification is not necessary, but in rainy weather, condensation, water droplets, or even water will appear in the switch cabinet. Dehumidification is necessary, which seriously affects The performance of the internal insulating material and the stability of the switchgear operation.

[0003] Since the equipment in the switchgear is in a relatively high temperature state when the equipm...
