摘要
通过对杆塔接地网进行实地调研,总结出湖北省超高压输电线路高土壤电阻率地区杆塔接地电阻偏高的原因,结合理论计算对常规降阻措施进行研究,提出适合湖北省高土壤电阻率地区实际情况的有效降阻措施,并选取典型杆塔进行接地网的降阻改造,被改造杆塔接地网达到了预期降阻目标,说明提出的改造措施切实有效,适合在湖北超高压输电线路推广使用。
Through field investigating the tower earth net,the cause of tower with rather high earth resistance in high soil resistivity area, where the Hubei UHV transmission lines passing through, was summarized. The conventional reducing resistance measures with theoretical calculation were studied. The effective reducing resistance measures suitable for the real situation of Hubei high soil resistivity area were put forward. The typical towers were selected to make earth net reducing resistance modification. The modified towers earth net attained the expected goal of reduced resistance.
