摘要
针对煤矿井下变电所原低压馈电开关保护性能不完善,不具备远程监控等问题,对馈电开关的综合保护装置进行升级改造。改造后的保护装置,具备远程合闸、分闸、试验、复位、查询等功能,系统运行安全可靠,满足了“四化三减”要求,变电所实现了无人值守。
In view of the problems of imperfect protection performance and remote monitoring of the original low voltage feed switch in the underground substation of coal mine,the comprehensive protection device of the feed switch is upgraded and reformed.The modified protective device has the functions of remote closing,opening,testing,reset,inquiry and so on.The system is safe and reliable,which meets the requirements of“four modernizations and three subtractions”,and the substation is unattended.
