高塔直击雷雷电流全波监测系统

Full-waveform measuring system for lightning current caused by lightning strikes to tall structures

分析和研究雷电流的波形参数是雷电电磁脉冲 (LEMP)防护的基础 ,天然落雷的雷电流全波测量对防雷理论及防雷设计都有重要意义。介绍了江阴长江公路大桥北塔上的雷电流监测系统 ,以及本测量系统的标定、系统的模拟实验等问题。

In order to protect electronic devices against the effects of lightning strikes to tall structures, detailed information about the lightning currents are necessary. For this purpose, a full waveform measuring system was set up on north towers of Jiangyin Highway Bridge. The calibration to this system is introduced and the test results of simulating lightning currents are given.
