摘　　要：首先对雷电流的波形进行分析,对雷电流数学表达式进行傅里叶变换,然后得出雷电流的频谱和能谱的分布函数,绘出频谱图和能谱图,找出雷电危害的重要波段所在。结果对避雷方案的设计、避雷器件的选取和雷害的评估具有重大的指导意义。Being based on analyzing waveform of Lightning current,using Fourier transform to study mathematical expression of Lightning current.so as to come up frequency spectrum function and energy spectrum function of Lightning current,And obtained frequency spectrum image and energy spectrum image of Lightning current.It help us to find out important wave band of harm of lightning.Which is very important for us to design of Lightning protection program and choice of lightning arrester and evaluation of lightning harm.

关 键 词：雷电流 傅里叶变换 频谱 能谱
