摘　　要：本文从探索如何获取接触网雷电特征参数和如何确定雷击故障位置出发,阐述了分布式接触网雷电在线监测及故障定位系统研发及应用。通过获得并初步分析接触网雷电流参数,掌握接触网雷击干扰的性质,进而实现接触网雷击故障点定位,可为运营设备抢修提供有效的指导意见,为雷击事故分析和处理提供原始依据。本研究成果也可为今后从理论层面深入研究牵引网雷电机理、建立分析模型、实施雷电危害差异化评估提供有效的技术手段和研究方向。Starting from obtaining the characteristic parameters of lightning and determination of fault locations of OCS, the paper illustrates development and application of online monitoring and fault location system for lightning on OCS. The obtaining and analyzing of lightning current parameters of OCS, mastering of OCS lightning interference properties, thus realizing of fault location of OCS lightning fault location may provide guiding proposals for emergency rescue of equipment operation, provide original basis for lightning fault analysis and disposal. The results of this research may also provide effective technical means and direction of researching for establishing of analyzing model for deep study of lightning mechanism for traction network in terms of theoretical level and differentiated assessment of lightning risks.
