[0002] Switchgear is a general term for high-voltage power distribution cabinets, generators, transformers, power lines, circuit breakers, low-voltage switchgear, switchboards, switch boxes, control boxes and other power distribution equipment in the power system. AC metal-enclosed switchgear is the introduction of advanced Technology and in accordance with the requirements of domestic rural power and domain network transformation, a new generation of medium-voltage electrical products has been successfully designed and developed. After strict type tests and long-term operation assessments, all technical performance indicators have reached IEC298 and GB3906 standards, with small size , light weight, beautiful appearance, easy operation, long life, high parameters, no pollution, less maintenance and other outstanding features, suitable for AC 50hz, 10kv power network, used for receiving and distributing electric energy, AC metal-enclosed switch The equipment needs to be used under the conditions that the altitude does not exceed 1000 meters, the ambient air temperature is not higher than +40°C, not lower than -5°C, and the surrounding air is not significantly polluted by corrosive gases, flammable gases, and water vapor. ; When the armored open-type indoor AC metal-enclosed switchgear works for a long time in a place with high altitude and high ambient humidity, the water vapor inside it will easily condense into water due to temperature changes, which will affect the safe operation of the equipment and cause installation hazards Therefore, it is necessary to provide a dehumidification device for armored open indoor AC metal-enclosed switchgear that can effectively remove moisture in the switchgear and ensure its long-term safe operation.
