摘　　要：对冲击电流下输电线路杆塔的接地阻抗特性进行了论述,并选取其中3种影响冲击接地阻抗感性分量的因素做了图表分析,最后利用基于冲击接地法的频谱法分别进行实验室模拟试验和巴中江城输电线路部分杆塔接地体的现场试验,取得了理想的测量效果。实践表明该方法对今后接地阻抗的测量工作有指导性意义。The characteristics of earthing impedance of poles and towers in transmission line under surge current are discussed. Three kinds of influencing factors for inductive component of impulse earthing impedance are selected for chart analysis. Final- ly, the laboratory simulation experiment and the field test for earthing electrode of some poles and towers in transmission line in Jiangcheng of Bazhong are carried out with spectral method based on impulse earthing method, and the ideal measurement re- suits are obtained. The practice shows that the proposed method has the guidance significance for the future measurement of earthing impedance.
