漏电保护器在煤矿井下安全供电中的作用

Function of Residual Current Operated Protective Devices in the Safe Power Supply of Coal Mine

煤矿井下环境特殊,如空气相对湿度大,环境温度高,施工条件差,影响煤矿井下安全供用电。针对井下供电系统中发生漏电的原因,漏电的危害,提出了预防漏电的措施。

The underground environment of mines is very special,such as high relative humidity,high temperature,poor constructing conditions,which affect the safe power supply of coal mine.Aiming at the reasons and harms of leakage current in the power supply system of coal mine,the article proposes measures to prevent leakage current.
