ATCS-220 Intelligent Electrical Cabinet Dehumidifier
Product Description
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.

Working Principle
The Intelligent Electrical Cabinet Dehumidifier consists of power supply system, air supply system, semiconductor cooler, temperature and humidity controller, heating circuit, communication module and drainage pipeline.
1.Dehumidification principle
When the humid air is inhaled by the fan, it flows through the specially designed air duct, first cools down and condenses by the semiconductor refrigeration device, and the condensation of the refrigerator drips into the lead tank under the action of gravity, and then flows out of the cabinet by the guide pipe. After a full cycle of dehumidification, the cabinet air humidity down to the condense point, to complete the entire moisture-proof lead condensation heating process. At the same time, the signal collection sensor can real-time accurately collect the real humidity in the cabinet, to ensure that intelligent dehumidification device in the cabinet will start dehumidification before condensation point is reached.
2. Communication control function
When the dehumidifying device with communication control function receives the data from the main control room, the data will be analyzed and immediately returned to the main control room
