Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage switch cabinets, in particular to a high-voltage switch cabinet with dehumidification and anti-condensation functions. Background Art

[0002] High-voltage switchgear refers to the switchgear used for power generation, transmission, distribution, power conversion and consumption in the power system, and plays the role of switching, control or protection. High-voltage switchgear is divided into several categories, such as electrical products with voltage levels of 3.6kV to 550kV, high-voltage disconnectors and grounding switches, high-voltage load switches, high-voltage automatic reclosing and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices and high-voltage switchgear. It is mainly suitable for various places such as power plants, substations, petrochemicals, metallurgical steel rolling, light industry and textiles, factories and mines, residential areas, high-rise buildings, etc.

[0003] Humidity is divided into absolute humidity and relative humidity. Absolute humidity refers to the mass of water vapor in each cubic meter of air. Condensation refers to the phenomenon that water vapor condenses on objects with relatively low temperature when it reaches the saturation level in the air.

[0004] One of the normal use conditions of high-voltage switchgear is that the daily average relative humidity is not more than 95% RH, and condensation refers to the condensation of water vapor in the air into water droplets when the ambient temperature is lower than the dew point temperature of the relative humidity of the air. Under the same environmental conditions, the higher the relative humidity of the air, the closer the dew point temperature is to the ambient air temperature, and the easier it is for condensation to occur. Operation has proved that humid air and condensation are important causes of insulation failure in high-voltage cabinets.

[0005] Therefore, it is necessary to provide a high-voltage switch cabinet with dehumidification and anti-condensation functions. Utility Model Content
