双电源快速切换装置在上社煤矿的应用

Application of Double Power Fast- switching Supply Device in Shangshe Coal Mine

上社煤矿在矿井变电站进线、主变低压侧母线、主要通风机房母线等煤矿供电系统中采用双电源快切装置,针对矿井供电系统的运行方式、主变的运行方式、以及矿井的不同负荷类型,制定了合理的快切配置方案和起动、闭锁条件,有效的避免了煤矿双电源供电系统因突发故障造成的大面积停电事故的发生。

In Shangshe Coal Mine,the double power fast- switching devices were allocated at coal mine substation inlet line,low-voltage line side of main transformer and line side of main fan room in coal mine power supply system. For the different operation modes of coal mine power supply system and main transformer,and different load types of mine,it made rational fast switching scheme,starting conditions and locking conditions,which effectively avoided the occurrence of large area blackout accidents caused by sudden fault in coal mine power supply system.
