摘要
电力系统雷击远程在线监测系统是一种自然雷击电流波形数据采集装置,它利用Rogowski线圈电流传感器将雷电流转化为电压信号,并实现了雷电流波形数据的高速采集和远程无线传输;系统通过服务器专用软件实现雷电流波形浏览和电力系统雷击类型、故障方式等判定。系统安装于输电线路和塔式避雷针上,经过2年野外运行,已经成功获取4组自然雷击电流波形数据。与实验室常规冲击电流试验波形相比,这4组雷击电流波形数据中存在波头时间小于1μs和波形幅值激烈振荡的特性。
Remote online monitoring system of power system lightning current is a data acquisition equipment of natural lighting current waveform for power system,which applies the Rogowski coil to transform the lighting current to voltage signal and realizes the high-speed data acquisition and wireless data transmission of lightning current waveform.Special server software is used to display waveform and determine the lightning type and fault mode.The equipment is installed on transmission line or lightning rod.Four sets of lightning current waveforms have been recorded during 2 years’ field operation.Compared with the laboratory impulse current waveforms,the natural lightning current waveforms have the wave head of less than 1 μs and the violent vibration of wave amplitude.
