摘　　要：为适应超特高压输电线路的快速发展,提高电力工程检修的工作效率,针对耐张塔内角侧接地线挂接困难的情况,提出一种新型接地线设计方案,并与传统型接地线对比分析。将模型样品进行现场应用试验和安全试验,发现该新型接地线可以实现接地线远距离手抛挂接和拆除工作,且自身重量大幅度降低。结果表明,新型接地线较棒式接地线质量降低54%,不仅适用于超特高压耐张转角杆塔内角侧接地挂拆,还可根据.需要变更接地线的长度及截面,应用于不同塔型及各个电压等级的输电线路,具有较高的实用价值。In order to adapt to the rapid development of ultra high voltage transmission line and improving the fficiency of power engineering of all kinds of maintenance work,in view of the angle of a tower grounding resistance line articulated difficult situation,this paper states a new ground wire structure which is an optimal solution by checking the docking ground parts.The demo of model has been tested by safey experiments in real working situation.It finds that the new style structure of ground wire can be used by hand in a long distance and lose weight sharply.The result of research shows that the weight of the new grounding wire is 54%lower than that of the bar grounding wire,while it not only apply to tensioning corner tower,but also is used to change the length and section of grounding wire according to the needs.It has high practical value in application of different tower shapes and different voltage levels.
