煤矿井下低压供电系统漏电保护的方法研究

Leakage Protection Methods of Low-voltage Power Supply System in Underground Coal Mines

煤矿井下低压供电系统是煤矿生产运营的基本保障。井下低压供电系统存在很多潜在危险,其中漏电是最常见的一种。漏电会严重影响煤矿开采以及作业人员人身安全,因此,煤矿企业做好漏电保护至关重要。主要介绍了低压供电系统中漏电的原因,提出了具有可行性的漏电保护方法,为煤矿解决低压供电系统漏电问题提供借鉴。

Underground low-voltage power supply system is the basic guarantee of coal mine production and operation.There are many potential hazards in underground low-voltage power supply system,among which leakage is the most common one.Leakage will seriously affect the safety of coal mining and operators,so it is very important for coal mine enterprises to do a good job of leakage protection.The causes of leakage in the low-voltage power supply system were mainly introduced,and the feasible leakage protection methods were put forward,which can provide reference for coal mine in solving the problem of leakage in the low-voltage power supply system.
