摘要
在介绍铁路自闭/贯通线路行波故障测距原理的基础上,系统地介绍了一种适用自闭/贯通线路的行波故障测距装置的系统结构、工作流程、所解决的各种关键技术等,最后给出一个现场运行的实例。该行波测距系统结构合理、工作可靠,对于自闭/贯通线路故障的准确、迅速定位,提高供电可靠性,以及对铁路电力系统的安全稳定和经济运行都具有十分重要的作用。
Based on the analysis of the traveling wave based fault location principles, a fault location system is introduced systematically with its system structure, function flow, and some key techniques for realization of fault location for 10 kV automatic blocking/power continuous lines in railway power systems. In the end, a field example is presented, The field results show that the fault location system has reasonable structure and high reliability. It is very significant for quick and accurate fault location, high reliability of power supply, and the safe and economic operation for railway power systems.
