摘　　要：电力系统中的高压开关柜受水分侵蚀后性能会下降并将导致柜内关键部件故障率升高,威胁到电力系统的可靠性。通过设计与优化半导体冷凝系统,并开展模拟除湿实验,研究了半导体冷凝除湿装置的除湿效果。实验采用聚乙烯薄膜搭建与现场开关柜尺寸相似的密闭空间。实验结果表明:半导体冷凝除湿装置的平均除湿速率高于0.25/h,改善散热条件能提高除湿效率。相比于传统电加热除湿,半导体冷凝除湿从源头上实现了开关柜的水分含量控制。The high voltage switchgear in the power system will experience performance degradation and an increase in the failure rate of key components inside the cabinet after being corroded by moisture,posing a threat to the reliability of the power system.This article conducts simulated dehumidification experiments by designing and optimizing semiconductor condensation systems,and studies the dehumidification effect of semiconductor condensation dehumidification devices.The experiment used polyethylene film to construct a closed space with similar dimensions to the on-site switchgear.The results show that the average dehumidification rate of semiconductor condensing devices is higher than 0.25/h,and improving heat dissipation conditions can improve dehumidification efficiency.Compared to traditional electric heating dehumidification,semiconductor condensation dehumidification achieves moisture content control of switchgear from the source.
