摘　　要：为了解决监控系统传统馈电传感器监测不准确问题,通过在馈电闭锁开关中加装延时继电器与交流接触器,并引接出一组无源端子开关信号,将该开关信号接入矿井安全监控系统。闭锁馈电开关的送电与停电控制交流接触器的吸合与断开触发无源端子触点动作,输出开与关的电信号并上传到安全监控系统,可以准确地监控到闭锁馈电开关的送电与停电状态。In order to solve the problem of inaccurate monitoring of traditional feed sensor in monitoring system,a group of passive terminal switch signals are connected by adding delay relay and AC contactor to the feed locking switch.The switch signal is connected to the mine safety monitoring system.The power transmission and blackout of the latch feed switch control AC contactor suction and disconnect trigger passive terminal contact action,output the electric signal on and off and upload to the safety monitoring system.The power transmission and power failure state of the latch feed switch can be accurately monitored.
