Intelligent dehumidification device is a semiconductor refrigeration dehumidification method, the humid air in the closed space is actively drawn into the dehumidification duct under the action of the fan, and the water vapor in the air is condensed into water after passing through the semiconductor refrigeration mechanism and then discharged out of the cabinet through the conduit pipe, so that it can achieve good dehumidification effect. By reducing the water content in the air, so that the relative humidity and absolute humidity at the same time down, almost do not raise the temperature, does not produce the negative impact of the temperature difference, fundamentally eliminate or reduce the occurrence of accidents, but also not due to high temperatures and accelerate the aging of the cabinet devices and cabinets. Intelligent dehumidification device to passively prevent condensation, changed to actively guide the condensation, effectively preventing the cabinet equipment aging, insulation strength reduction, the second terminal breakdown, material mold and corrosion of steel structural components and other safety hazards, to ensure the safe operation of the power grid. Condensation inside the equipment caused by creepage, flashover accidents, generally occur in the following situations. 1:
1. high humidity in the region, big change of weather temperature, wet bottom of switchgear, some cable trench and even water.
There is even water accumulation;
2. There are switch cabinets in the basement, high humidity, the temperature inside the cabinet, especially close to the ground
The temperature is lower than the ambient temperature;
3. is that some of the equipment is temporarily out of operation, electrical cabinet within the small ambient temperature is lower than the surrounding environment.
The temperature of the environment is lower than the surrounding environment, in its surface is very easy to form condensation, in this case, once the power supply cast
In this case, once the power is put into operation, accidents will occur.
In order to ensure the safe operation of the power grid system, the long life of electrical equipment, safe and effective use of
Power system on the cabinet moisture-proof, anti-condensation dew put forward higher requirements.
