摘要
为了提升煤矿生产的安全性,祥升煤矿对该矿的供电系统进行了防越级改造。介绍了防越级跳闸系统应该具有的功能,并分析了KJ171煤矿供电防越级跳闸监控系统的工作模式。通过在祥升煤矿的应用可以发现,该系统防越级跳闸具有选择性、快速性(零时限)和可靠性,保障了煤矿的安全生产。
In order to improve the safety of mine production,Xiangsheng Mine made an anti-overstep modification to the power supply system of the mine.The anti-crossing trip system were introduced,and the working mode of the KJ171Mine power supply anti-crossing trip monitoring system was analyzed.Through the application in Xiangsheng Mine,it can be found that the system had selectivity,rapidity(zero time limit)and reliability in anti-step-over tripping,which guaranteed the safe mining.
