西铭矿风机房供电系统快速切换技术研究

Research on Fast Switching Technology of Power Supply System in Ximing Mine Ventilation Fan Station

在电源线路发生故障的情况下,为了达到及时检测和识别问题,并迅速确定发生故障位置、进行自主隔离、同时达到快速切换的目的,真正实现“风机不停、瓦斯不超限”,研究了西铭矿风机房现有的继电保护配置方式,探讨了快速切换原理以及动作切换情况,分析了切换时的电流电压波形。试验应用表明,快切装置切换正常。

In the case of a power supply line failure,in order to detect and identify the problem in time,quickly determine the location of the failure,automatically cut the failure line,and achieve the purpose of rapid switching at the same time,and truly realize the ventilation Fan does not stop and the underground gas does not exceed the limit.The existing relay protection configuration mode of Ximing mine ventilation Fan station is studied.
