摘　　要：电抗器绕组支路电流的稳定性是衡量电抗器质量水平的重要指标。本文针对高次谐波分量存在时影响电抗器绕组电流分布的不均问题,给出了支路电流的矢量计算方法,将复杂的矢量分析转化为计算机软件进行计算,分析了高次谐波分量对支路电流的作用。通过具有普遍性的10种高次谐波算例比较分析,发现绕组数据确定时某次谐波分量下支路电流呈现稳定状态,然而在其他次数谐波分量下支路电流呈现较大差异。The stability of branch circuit current ot reactor winding is an important index to judge quality level of reactor. As for the issue causing uneven current distribution of reactor winding with high order harmonics component existed, a vector calculation method of the branch current is given, the complicated vector analysis is transferred into computer software for calculation. It is found through comparison and analysis of calculation examples of 10 kinds of high order harmonics with u- niversality that the lower branch current; in case of while it, in case of other order harmonic components, determination data, shows steady condition; shows bigger difference.
