摘要
分析了变电站直流电源系统几种比较典型的、与平衡桥电阻有关的接地故障的处理过程与方法,包括全接地故障、断开负荷发生接地故障、2套直流系统交替出现接地故障、蓄电池接地故障等;提出了用于变电站直流电源系统接地故障检测的平衡桥电阻的配置原则及注意事项。
The procedure and method for treating several typical,balance-bridge-concerned ground faults of substation DC supply system are analyzed,which include full ground fault,ground fault caused by load disconnection,alternate ground faults of two DC systems,ground fault of storage battery,etc.The configuration principles and points for attention of balance bridge resistance for detecting the ground fault of substation DC supply system are also proposed.
