一种新型配电网雷击点定位装置的研制

Development of a New Lightning Strike Positioning Device for Distribution Network

通过对配电网雷击过程的分析,提出了一种基于罗氏线圈的雷电流监测与定位系统,系统利用罗氏线圈电流传感器通过对接地线的耦合实现对雷击闪络过程中流入接地线的雷电流的测量,然后利用4G网络将雷电流大小和监测装置编码上传到监控平台,监控平台利用所构建的雷电流监测装置的编码和杆塔的对应关系,实现对配电网雷击点的可靠定位。

Through the analysis of the distribution network lightning process, this paper puts forward a kind of lightning current monitoring and positioning system, using Rogoswki coil current sensor to realize the lightning current into the grounding wire during lightning flashover. 4 G network is applied to upload the lightning intensity and the monitoring device code to monitor platform. The monitoring platform realizes the positioning of lightning strike points in the distribution network by using the corresponding relationship between the code of lightning current monitoring device and the tower.
