矿用传感器双电源供电自动切换的设计

Mine Sensor Design of Double Power Supply Automatic Switching

针对采掘工作面传感器提供两路供电电源,一路为专用电源,一路为备用电源。设计了两路电源之间能够实现自动切换,避免因传感器自动断电造成环境监测的中断,系统进行故障闭锁,进而切断采掘工作面及其回风巷内的所有非本质安全型电气设备,影响生产和环境监测,产生安全隐患。

Two power supply for sensor mining face, a road is a road for the special power supply,standby power supply. The design of the power supply can realize automatic switching between the two,to avoid interruption due to automatic power-off sensor caused by environmental monitoring, fault block system, cutting surface and mining work in the wind Lane all non intrinsically safe electrical equipment and then, influence the production and environmental monitoring, security risks.
