摘要
对AT供电牵引网断线故障进行了理论分析,结合具体算例,给出各种断线接地故障的阻抗─—距离特性曲线,通过与其它短路故障比较,从理论上论证了AT牵引网发生断线故障时常规保护拒动的可能性。
In this paper, the complex grounding fault with interruption of AT traction system is analysed. And the impedance-distance curves of this fault and the routine faults are presented. Through contrast with the routine faults, the possibility of the conventional protection refusing to trip is certified while the complex grounding fault with interruption occurs.
