摘要
首先阐述了煤矿供电系统越级跳闸产生的原因,主要包括保护控制装置出现问题、电压不稳定、继电保护不到位等原因,并在此基础上分析了煤矿供电系统防越级跳闸技术及其应用,可以有效防止供电系统的越级跳闸现象。
At first,this paper expounds the causes of leapfrog trip of power supply system in coal mine,mainly including protect reason control equipment problems,voltage instability,relay protection is not in place,and on this basis,analyzes the coal mine power supply system anti override trip technology and its application,to effectively prevent anti overstep tripping phenomenon of power supply system.
