注入法故障定位系统在铁路故障测距中的应用

The application of injection method fault location system in railway

阐述了铁路自闭/贯通线路常见故障现象及造成的危害,介绍了三种常见解决方法及原理,重点探讨了基于注入法的自闭贯通线故障定位系统,指出基于S注入法的应用可有效地解决自闭贯通线单相接地故障查找困难、排除时间长等难题,且定位精度较高。

The comnon fault phenomenon and harm were of railway automatic Dlocking transmission line explained, three common solution methods and principle were introduced, the injection method automatic blocking transmission line fault location system was discussed impor- tantly, and pointed that the application of S-injection method can solve single-phase-to ground fault seeking difficulties of automatic blocking transmission line effectively, eliminate the problem of long time, and the positioning precision is high.
