摘　　要：文中就朔黄铁路龙宫变电所212#断路器连续跳闸的故障为依据,以解决长梁山隧道保护线与受电弓包络线绝缘距离不足影响正常行车为目的,针对跳闸发生的直接原因,通过采取下降保护线高度,改移保护线肩架位置,以及后续的周期性巡检和隧道集中修等措施,保障设备安全运行,经施工改造,彻底解决了长梁山隧道因此类设备运行不稳定而造成的跳闸,也为类似施工提供了参考依据。Based on the fault of 212DL continuous tripping in Shuohuang Railway Longgong substation,in order to solve the transport interrupting problem caused by insufficient insulation distance between the PW of Changliangshan tunnel and pantograph envelope,this paper suggests to reduce the height of PW,change the shoulder frame position of PW.Then take following periodic inspection methods and centralized tunnel repair.After all these measures implementation,the tripping phenomenon caused by unstable equipment operation could be completely solved,which also providing a great reference example for the other similar constructions.
