井下低压供电漏电安全隐患及控制

Potential Safety Hazard and Control of Electricity Leakage in Underground Low Voltage Power Supply

井下作业是当今煤炭开采的主要作业形式,井下低压供电漏电安全隐患已经成为影响企业收益及工作人员安全的重要问题,通过分析井下低压供电漏电的原理,总结几种现有的漏电保护选线方式,希望能对井下漏电的控制起到借鉴作用。

The underground work is the main operation form of today＇s coal mining, and the potential safety hazard of electricity leakage in underground low voltage power supply has become an important issue affecting corporate earnings and staff safety. By ana- lyzing the principle of electricity leakage in underground low voltage power supply, this paper summarizes several current leakage protection line selection mode, hoping to play a reference role in the control of underground electricity leakage.
