摘　　要：对于高压开关柜闪弧故障的监测保护,已得到业内的重视,但对于煤矿井下低压开关的故障监测定位,目前仍是空白点。由于特殊的运行环境和隔爆外壳,井下低压开关闪弧故障概率更高,文章提出了适用于煤矿井下低压开关闪弧故障的监测定位系统,实现了故障后的定位告警和环境监测,方便故障检修和快速复电。The monitoring and protection of flashing arc fault of high voltage switchgear has been paid attention to by the industry,but it is still a blank point for the fault monitoring and location of low voltage switch in coal mine.Because of the special operating environment and flameproof shell,the probability of underground low-voltage switch flash arc fault is higher.This paper puts forward a monitoring and location system suitable for underground low-voltage switch flash arc fault in coal mine,which realizes location alarm and environmental monitoring after the fault and is convenient for fault maintenance and rapid power recovery.
