摘　　要：研发了基于导线互感取能的输电线路雷击故障点定位系统,实现了输电线路雷击故障点的精确定位。重点介绍了导线互感取能单元的设计、实验验证及特性,该系统采用罗氏线圈作为电流互感器实现对雷电电流信号的捕捉,采用GSM无线网络实现监测终端和监控中心的通信及报警,采用ZigBee无线网络实现三相监测终端间的通讯。试验结果表明该系统可实现输电线路雷击故障点的精确定位。A new location system of lighting faults in transmission lines based on mutual induction was designed by which the precise location of lighting faults in transmission lines could be realized. This paper focused on line mutual induction unit＇ s design, experimental verification and characteristics. The system used the Rogowski coil current transformer to capture the lightning current signal, realized the communication and alarm between monitoring terminal and control center by using GSM wireless network, and the communication among three phases monitoring terminal by using ZigBee wireless network. The results show that this system can precisely locate the lighting faults of transmission lines.
