摘    要:随着人民生活水平的提高,非线性用电设备大量使用,这方便和提高了人们的生活质量,但非线性负载会给三相供电线路注入谐波电流,引发中性线过载。从配电系统谐波电流的产生、危害入手,应用Fourier级数分解方法对非正弦周期电流进行理论分析,得出三次谐波及其奇数倍谐波会在中性线产生叠加效应,再加上三相负载不平衡,造成中性线过载,进而引发火灾事故的结论。

关 键 词:谐波电流  产生  谐波分析  中性线过载  火灾隐患

Abstract:Although it benefits the people a lot by uses of non - linear electric equipment, non - linear load sends harmonious electric current into three - phrase lines and causes over load of neutral lines, which leads to fire accident in turn.
Keywords:harmonic electric current  bring  harmonious analyzing  over load of neutral lines  fire risk
