摘要

为了了解实际雷电流的波形参数

需在高塔或输电线路等构筑物上对雷电流波形进行监测

但实际测量到的结果是受构筑物影响后的雷电流。笔者主要讨论雷电流监测装置安装位置对于监测结果的影响。在构筑物模型中考虑了雷电流传播过程中的衰减、畸变以及冲击接地电阻等的因素

采用电磁暂态分析程序对不同高度的构筑物进行仿真计算。分析结果表明

构筑物在不同安装位置处得到的雷电流差别很大

顶部监测到的电流受到的影响很小

底部监测到的雷电流受到的影响非常大

雷电流测量设备应当安装在构筑物顶部

这样测量到的雷电流参数比较准确。

Abstract

In order to obtain the waveform parameters of lightning current

monitoring devices should be installed on tall structures such as tower and transmission line.However

the measured results are influenced by the structure involved.Investigating the current distortion due to reflection and propagation effects is necessary to establish the relations between original and measured lightning current parameters.The purpose of this paper is to discuss the influence of installing position of lightning monitoring device on the measured result.Some factors are taken into account in building an electromagnetic transient model of structure

such as the attenuation and distortion of lightning current waveform in propagation

and the impulse grounding resistance of grounding device.The electromagnetic transient analysis program is adopted to simulate the electromagnetic transient process when a lightning strikes the structure with different heights.Simulation result shows that lightning currents exhibit huge disparity at different positions of the structure.The lightning monitoring device should be installed on the top of structure to get accurate lightning parameters.
