摘　　要：弧焊电源对电网来说,本质上是一个大的整流电源,工作中会产生严重的谐波污染。电网谐波污染会带来与经典的纯正弦波相违背的结果,降低功率因数,并造成极大的能量浪费,干扰周边用电设备。对晶闸管CO2焊接电源焊接过程主变压器一次侧产生的谐波信号进行采集分析,以此研究焊接电源对电网的影响。Welding power source is a commutate power source to the main,which results in serious harmonic pollution,and breaches the result of pure sine wave,decrease power factor,as well as wastes much energy and interferes the electro-equipments.This paper collects and analyzes the harmonic signals of the CO2 welding machines main transformer,by which researches the effect of welding power source on the main.

关 键 词：谐波 电能质量 功率因数 焊接电源
