摘　　要：分析了目前矿井低压电网漏电保护系统存在的不足,提出了基于电力载波通信的新型选择性漏电保护实现方案,介绍了装置的组成和工作原理。实验证明,该装置构成的漏电保护系统具有实时性强、选择性判断准确和可靠性高等优点。According to the analysis of the insufficiency of low voltage electrical network leakage protection system of mine presently, the new selective leakage protection mothod based on power line communication was proposed, and the composition and principle of the installment was introduced in detail. The experiment proved that the leakage protection system has merits of strong real-time, exact judgement of selectivity and high reliabitity.
