ATCS220 Smart Function Intelligent Dehumidifier with RS485 Interface for Electrical Cabinet Dehumidifying

ATCS-220 Intelligent Electrical Cabinet Dehumidifier adopts semiconductor refrigeration dehumidification method, the humid air in the closed space is sucked into the dehumidification duct under the action of the fan, and the water vapor in the air is condensed into water after the semiconductor refrigeration mechanism, and then discharged from the cabinet through the guide pipe, which can achieve a good dehumidification effect. The relative humidity and absolute humidity are lowered by reducing the moisture content in the air, almost no increase in temperature, fundamentally reduce accidents caused by raising temperature, also no accelerate the aging of the cabinet devices because of high temperation. Instead of passively prevent condensation, this Intelligent dehumidification device will actively guide condensation, effectively prevent the cabinet equipment aging, insulation strength reduction, secondary terminal breakdown, material mold and steel structure rust and other security risks, to ensure the safe operation of the power grid.

Condensation in the equipment causing creepage, flashing accidents, are generally occured in the following situations: 1. the region is high humidity, big weather temperature changes, wet switchgear bottom, some cable trench even soaked by water; 2, some switchgear are equiped in basement with high humidity, the cabinet body temperature is lower than the ambient temperature; 3, some equipment is in a temporary shutdown, the electrical cabinet internal temperature is lower than Ambient temperature, which is highly likely to form condensation, in these cases, the accident may occurr once the power is on operation. In order to ensure the safe operation of the power grid system, the long life of electrical equipment, the power system has put forward higher requirements on the cabinet moisture, condensation prevention.
