| 摘 要： | 首先对雷电流的波形进行分析,然后对雷电流的脉冲函数模型进行傅里叶变换,得出雷电流的频谱函数、雷电流峰值比率的频谱及雷电流峰值比率积累的频谱,在给定波形的条件下绘出雷电流的频谱图、雷电流峰值比率的频谱图及雷电流峰值比率积累的频谱图,然后找出雷电危害的重要波段所在。这对雷电防护装置的设计具有重要的指导意义。

| Abstract: | Being based on analyzing waveform of Lightning current and using Fourier transtorm to study Pulse function of Lightning current.We conclude that spectrum frequency function of Lightning current and spectrum frequency distribution of Lightning current apex valve rate and spectrum frequency distribution of Lightning current apex valve rate ogive.And obtained spectrum frequency image and spectrum frequency image of Lightning current apex valve rate and image of Lightning current apex valve rate ogive.It help us to find out the important wave band of harm of lightning.Which is important for us to design of Lightning protection program and choice of lightning arrester and evaluation of lightning harm. |
