| 摘 要： | 分裂间距的变化将直接影响到输电线路的导线表面电场,进而对输电线路的可听噪声、无线电干扰、地面电场、自然功率,乃至线路走廊宽度都产生不同程度的影响。以750 kV输电线路为例,计算和分析了分裂间距对输电线路的可听噪声、无线电干扰、地面电场、自然功率,线路走廊宽度的影响,并对750 kV输电线路分裂间距的合理取值提出了建议。

| Abstract: | The variation of the spacing between intra-bundle conductors directly affects the surface electric field of transmission conductor,and then the audible noise and radio-interference of transmission line,the ground electric field under the transmission line,the natural power and even the width of corridor are affected in different extent.Taking 750 kV transmission line for example,the affections of intra-bundle conductor spacing on audible noise,radio-interference,ground electric field,natural power and width of corridor were calculated and analyzed,and some suggestions on rational choice of the spacing between intra-bundle conductors of 750kV transmission line were proposed. |

| Keywords: | 750 kV transmission lines bundle conductor spacing reasonable choice of value |
