Study on Leakage Detection of Underground Low-voltage Power Supply System

以井下低压供电系统漏电检测为对象开展探究。针对井下漏电监测应用需求,分别对常用的零序电压检测法和附加电流检测法的作用原理进行深入探究,并对两种方式在低压供电系统漏电检测中的应用效果做出分析。分析得出,附加电流检测法能够更好地应用于低压供电系统漏电检测作业中,希望能够为其他矿井相似工程的开展提供借鉴和参考。

Study on the leakage detection of the underground low-voltage power supply system was carry out.According to the application requirements of underground leakage monitoring,this paper discussed the principles of the commonly used zerosequence voltage detection method and the additional current detection method deeply,and analyzed the application effect of the two methods used in the leakage detection of the low-voltage power supply system.The analysis shows that the additional current detection method can be better applied to the leakage detection operation of the low-voltage power supply system.It is hoped that it can provide reference for the development of similar projects in other mines.
