摘　　要：高压开关柜对电气设备的正常运行起到关键性作用,一旦发生故障将影响到整个电力系统,而凝露是造成高压开关柜故障的主要因素。在空气湿度较大时,室内墙上会有凝露现象,会导致空分装置10 kV高压柜出现烧毁事件。根据凝露产生的机理,提出采用基于半导体制冷技术防凝露处理措施,将被动除湿变为主动除湿,对保证空分装置正常运行具有重要的意义。High-voltage switchgear plays a key role in the normal operation of electrical equipment.Once a failure occurs,it will affect the entire power system,and condensation is the main factor causing the failure of the high-voltage switchgear.When the air humidity is high,there will be condensation on the indoor wall,which will cause the 10 kV high-voltage cabinet of the air separation unit to burn out.According to the mechanism of condensation,it is proposed to adopt anti-condensation treatment measures based on semiconductor refrigeration technology to change passive dehumidification into active dehumidification,which is of great significance to ensure the normal operation of the air separation plant.
