摘要
为更好地防止矿井供电系统发生越级跳闸故障,分析了煤矿供电系统越级跳闸事故的原因,总结了当前煤矿供电系统主要的防越级跳闸方法,并结合实际工作经验提出了一种基于“三位一体”的煤矿供电防越级跳闸监控系统。实际应用结果表明,该防越级跳闸监控系统能有效防范矿井供电系统发生越级跳闸故障,更好地保障矿井供电系统的连续可靠供电。
In order to better prevent the over-the-counter trip failure of mine power supply system,the cause of the over-level trip accident of coal mine power supply system is analyzed,the main anti-step trip method of coal mine power supply system is summarized,and a kind of three-in-one coal mine power supply anti-level trip monitoring system is put forward based on the practical work experience,the practical application results show that the anti-stepping trip monitoring system can effectively prevent the leap-level trip failure of the mine power supply system,and better guarantee the continuous and reliable power supply of the mine power supply system.
