(Summary description)双母接线的母线发生故障,在处理故障过程中要注意母线保护的运行方式,必要时应短时停运母线保护。  母线电压全部消失后,调度员应立即将可能来电的开关(包括母联开关)拉开,并通知操作队对母线进行外部检查。  当母线槽因故障导致电压消失同时有明显的短路象征(如火光、爆炸声、冒烟等情况),操作队人员不得自行恢复运行,应对母线设备进行详细检查。  连接在母线上的元件故障或由于分路开关拒动,造成越级掉闸使母线失

Information
The busbars of the double-female wiring are faulty. In the process of handling the faults, pay attention to the operation mode of the busbar protection. If necessary, the busbar protection should be stopped for a short time.
 
After the bus voltage has completely disappeared, the dispatcher should immediately pull the switch (including the bus couple switch) that may be incoming, and notify the operation team to perform an external check on the bus.
 
When the busway is faulty and the voltage disappears and there is a obvious short-circuit symbol (such as flare, explosion, smoke, etc.), the operation team personnel shall not resume operation by themselves, and the busbar equipment shall be inspected in detail.
 
If the component connected to the busbar fails or is rejected due to the shunt switch, the over-level trip will cause the busbar to lose voltage. Detailed inspection should be carried out to immediately isolate or disconnect the faulty component of the busbar slot and open the switch on both sides of the faulty shunt switch. Restore the bus operation and send other branches.
