高湿地区变电站开关柜受潮分析及治理

Moisture analysis and comprehensive control of substation switchgear in high humidity area

在某些地区由于高海拔、高温高湿、昼夜温差大的特点,导致在运的开关柜内部受潮,开关柜运行中局放数据超标、异常放电甚至导致开关柜烧毁。为彻底消除开关柜受潮隐患,改善运行环境,结合开关柜制造厂家及开关柜运行环境开展分析,提出开关柜防潮除湿措施。

In some areas,due to the characteristics of high altitude,high temperature and humidity,and large temperature difference between day and night,the internal dampness of the switch gear in transport is caused.In the operation of the switch gear,the local discharge data exceeds the standard,abnormal discharge and even lead to the burning of the switch gear.In order to completely eliminate the potential hazards of switch cabinets dampness and improve the operating environment,the moisture-proof and dehumidification measures of switch cabinets were proposed based on the analysis of the manufacturer and operating environment of the switch cabinets.
