煤矿井下低压电网常见故障防护技术研究

Study on Protection Technology of Common Fault of Underground Low Voltage Power Network

针对煤矿井下低压电网的用电安全性和稳定性,分析了井下低压电网常见的漏电、短路、断相和过载故障的发生机理、危害和防护措施等,介绍了相应故障的检测手段,并以此为基础,提出低压电网用电安全监控网络的构建方法,本文研究内容对矿井低压电网综合保护系统的建立具有重要参考意义。

In view of the safety and stability of low-voltage power network in coal mine,firstly studies the mechanism,harm and protection measures of leakage,short circuit,phase failure and overload fault in underground low voltage power network. Analyzes the construction method of low-voltage power grid safety monitoring network,and the content of this paper is of great reference significance to the establishment of integrated protection system for mine low voltage power network.
