煤矿井下供电继电保护相关问题的探讨

Research on Power Supply Relay Protection in Coal Mine

面对供电故障发生率逐年升高、供电系统越来越复杂的形势,提高继电保护效率是保证煤矿电网正常运行的必要条件。通过分析介绍供电系统中电力设备质量及人为因素引发的故障,提出了供电继电保护系统安全、稳定运行,有效预防电力事故发生相应的措施,以期为煤矿井下安全施工提供强有力的保障。

With the situation that the power supply failure rate is increasing year by year and the power supply system is more and more complicated,to improve the efficiency of relay protection is necessary to ensure the normal operation of the coal mine power network. In this paper,through analyzing the quality of power equipment and faults caused by human factors in power supply system,the corresponding effective prevention measures for the power relay protection system are then put forward so as to provide a strong guarantee for the safe construction of underground coal mine.
