摘要
根据郑西高铁故障测距的实际情况,结合"AT中性点吸上电流比原理"测距装置,分析故障测距失败的原因及危害。依据故障测距原理的同步性原则,计算丢失AT吸上电流,手动计算故障距离,为接触网的故障点查找提供理论依据,以缩短故障地点的查找时间。
According to the actual situation of fault location in the high-speed railway between Zhengzhou and Xi＇ an,combining the location equipment designed on AT neutral suck current ratio principle,The reason and danger of the failure of fault location is analyzed. According to the synchronization principal of fault location,The lost-AT suck current and fault distance are calculated manually to provide the theoretical basis for finding the fault point of overhead contact line so that the fault site finding time can be shortened.
