输电线路雷电流全波在线监测系统的研究

Full-waveform on-line Monitoring System of Lightning Current for Transmission Lines

介绍一种安装在输电线路上的雷电流在线监测系统。系统主要包括Rogowski线圈,高速数据采集电路、GPRS通信模块、计算机终端。该系统能够自动记录输电线路上的雷击电流参数,包括幅值,波形,时间,雷击地点等信息,并可将记录数据发送到指定服务器上的数据库中。对掌握雷电活动规律有一定实用价值。

This paper introduces an on-line monitoring system of lightning current which is mounted at transmission lines. This system mainly includes rogowski coil, high-speed date acquisition circuit, communication Module of GPRS, computer terminal. It can record the parameters of lightning current for transmission lines, such as amplitude, waveform, time, location and so on. It can also transmit data that have been recorded to the specified server. It has some practical value in mastersing the principles of lightning current.
