摘要
为准确计算雷电回击的电磁场 ,用击穿电流和电晕电流来拆分 IC标准雷电回击电流。前者用一种新型脉冲函数表示 ,后者用双指数函数表示。分别拆分拟合了标准中雷电首次回击和后续回击通道基电流。所得结果误差 <3%。
In this paper the standard current of lightning re-stroke is devided into breakdown and corona current based on IEC 1312-1. The breakdown current and corona current are represented by a new function and a double exponential function respectively. The first and subsequent re-stroke standard current are fitted. The results are useful for the research in the future.
