介绍了在井下采区变电所高爆开关中安设线路光纤差动保护装置取代原来配置的速断过流保护装置作为线路首保护，该装置应用在常村煤矿（高瓦斯矿井）庞大复杂的供电网络中，五年多正常运行而取得的显著效果。该保护系统可以实现“四遥”（遥测、遥信、遥控、遥脉）功能和有效避免煤矿供电网络中时常发生的“越级跳闸”现象，增强煤矿供电的连续性和可靠性，进一步提高电网运行的稳定性，为矿井安全有序生产保驾护航。

Mining underground mining area were introduced in substation high -explosive switch installed in the line optical differential protection device to replace the original configuration of instantaneous over -current protection device as the first protection circuit , and the device used in Chang Village coal mine (gas) mine complex power network, the normal operation of more than five years and a-chieved significant effect.This protection system can realize the "four control"(remote sensing, remote communication, remote con-trol, remote pulse) function and effectively avoid the frequent coal mine power supply network went "trip"phenomenon, enhance the continuity and reliability of the coal mine power supply , further improve the stability of power grid operation , orderly for mine safety production.
