摘　　要：参照国内现有研究成果与美国UL1699标准搭建串联电弧故障实验平台,采集电弧电流与电弧电压数据,提出线路电流高次谐波含有率分析方法.通过对不同负载电路电流数据高次谐波含有率变化情况的分析,总结出电弧故障引起的高次谐波含有率的变化特征.研究结果表明,电弧故障发生时电流高次谐波含有率出现急剧上升(均值增幅大于15%),同时高次谐波含有率不稳定,激烈波动.A series arc fault experiment platform was built with reference to the domestic existing research re- sults and the United States UL1699 standard. Are current and arc voltage were collected. A high order har- monic ratio analysis method for wire current was proposed. Through the variation condition analysis for a high order harmonic ratio of current data in different load circuits, the variation characteristics of a higher order har- monic ratio caused by arc fault was summed up. Research results show that： when arc fault occurred, the high order harmonic ratio of wire current appeared to rise sharply （ the mean value growth was more than 15% ） , and it was not stable, in a fierce fluctuation.
