For safety reasons, the high-voltage cabinet door is rarely opened, and most The high-voltage cabinets are all sealed designs, so the ventilation in the high-voltage cabinets is poor, and the high-voltage equipment in the cabinets is very easy to cause partial discharge due to moisture accumulation, which will cause safety hazards to the operation of the equipment. Especially in July and August, the climate is humid, and accidents caused by discharge caused by humid air are not uncommon. Furthermore, the equipment in the high-voltage cabinet releases heat during operation, so how to cool down the inside of the power cabinet and at the same time dehumidify is a problem.
