摘要
通过对输电线路不合格杆塔接地网进行分析,找出接地电阻超标原因,并根据杆塔的地理环境与土壤电阻率测试结果,结合纳米离子棒的降阻特性,采取不同的改造措施,有效降低杆塔接地电阻,提高输电线路防雷水平。
Based on analysis of unqualified tower grounding grid of transmission line, the reason of exceeding standard of grounding resistance is found out. And according to the towef's geographical environment and soil resistivity test results, combined with resistance reduction characteristics of nano ion bar, it takes different reform measures which effectively reduces the tower's grounding resistance and improves the level of transmission line lightning protection.
