Abstract

The invention belongs to the technical field of power distribution devices, and particularly relates to a cooling and dehumidifying switch cabinet environment control device which comprises a refrigerator. The refrigerator is connected with an air blower through a cooling liquid circulating pipe, the air blower is connected with a dryer, the dryer is connected with an air supply pipe, and the airsupply pipe penetrates through a switch cabinet protection chamber at the upper portion of a switch cabinet. The device adopts a pipeline air supply mode, is accurate and low in cold consumption, reduces air humidity through the moisture absorption allochroic silicagel, is installed in a centralized mode, saves the size, is low in transformation cost, is easy and convenient to operate, and is goodin temperature and humidity control effect and high in safety.

Description

technical field [0001] The invention belongs to the technical field of power distribution equipment, and in particular relates to a switch cabinet environment control device for cooling and dehumidifying. Background technique [0002] The power switch cabinet is suitable for power plants, petroleum, chemical industry, metallurgy, textile, high-rise buildings and other industries. It is used as electrical equipment for power transmission, power distribution and power conversion. The road is set according to its needs. The power switchgear will generate a lot of heat during the working process, and it needs to be discharged in time to dissipate heat. However, the general switchgear is only equipped with cooling holes for heat dissipation, and its cooling effect is not very good, especially in the hot summer, because there is no wind blowing in. The heat inside the switchgear does not condense, and the temperature will become higher and higher, resulting in damage to electrica...
