摘要

10/350μs冲击电流波的频带范围为几赫兹到1MHz

普通空心Rogowski线圈自身电感较小

测量低频部分会失真。针对该问题

笔者以磁性材料做骨架

制作了自积分式Rogowski线圈。在10/350μs冲击电流实验平台上与同轴管式分流器作了实验对比。结果表明

由于磁性材料的加入

大大提高了线圈的自感

也拓宽了线圈的下限频率

自制线圈频带的理论数值为2.182Hz

.924MHz。制作的线圈在82kA范围内能准确测量10/350μs波形

波头波尾时间与电流幅值误差均小于2%

能满足要求。

Abstract

Bandwidth of 10/350 μs direct lightning stroke current is from several Hz to 1 MHz

waveform distortion at low frequency section will occur when this current is measured by normal Rogowski coil due to its small self-inductance.In this study

a self-integral Rogowski coil with magnetic core was made.An experimental comparison with coaxial tube shunt was conducted on the platform of 10/350 μs impulse current generator.The results indicate that the self-inductance of the self-integral Rogowski coil is clearly enhanced

and its lower limit of frequency is extended because of the magnetic core.The theoretical bandwidth of the self-integral Rogowski coil is from 2.182 Hz to 2.924 MHz.10/350 μs impulse current waveform below 82 kA can be measured exactly.The errors of rise time

real time and current amplitude are all below 2%.
