Control device for high voltage switch cabinet

The invention provides a control device for a high voltage switch cabinet. The device comprises a temperature sensor, a micro processor, a ventilation mechanism, a pressure monitoring mechanism and a gas sensor. The state of the high voltage switch cabinet is determined by the micro processor according to the detection result of the gas sensor, whether the high voltage switch cabinet is abnormal can be determined according to the detection result of a pressure monitoring unit, if yes, pressure reduction for the internal portion of the high voltage switch cabinet is carried out through adjusting a gas exhaust volume of the ventilation mechanism, the micro processor is further used for receiving the temperature data acquired by the temperature sensor, when the temperature value surpasses the preset upper temperature limit value, the ventilation mechanism is controlled for ventilation of the high voltage switch cabinet. Through the device, the temperature of the high voltage switch cabinet is precisely realized,
