包神铁路牵引网故障测距计算及应用

Calculation and Application of Traction Network Fault Location on Baotou-Shenmu Railway

通过对牵引供电故障测距系统进行分析,建立直供加回流线供电方式下模型,通过分析直供加回流线供电方式故障测距原理,对包神铁路牵引网单位阻抗进行计算,将整定定值输入到继电保护装置中,完成实际运用,通过实际故障判断校验计算的准确性,从而指导接触网故障的查找,有效的压缩故障延时。

After analyzing the traction power supply fault location system, the model of direct feeding system with return wire is established, with the aid of analyzing the principles of fault location of direct feeding system with return wire, the actual application is accomplished with the aid of calculating the unit impedance of traction network of Baotou-Shenmu railway and inputting the setting values into the relay protection devices. The accuracy of verification and calculation of the actual fault is assessed on the basis of the actual faults, and it will help instruct the trouble shooting of overhead contact system faults and shorten the failure delay time.
