摘　　要：架空输电直流融冰技术由于其良好的融冰效果,在交流500 k V及以上线路导线融冰中得到广泛应用,地线融冰技术成为目前需要解决的问题。在500 k V施秉—贤令山线路防冰抗冰改造工程实践中,通过对地线直流融冰技术进行深入研究,针对本工程复杂的地线情况,进行了地线直流融冰计算与分析,提出适合本工程的地线融冰方案并加以实施,取得了良好的效果,本文根据工程实践并结合地线直流融冰技术提出下一步展望。Due to the good effect of DC based de-icing technique used in overhead transmission line, it has been widely used in conductor de-icing of 500kV and above AC transmission line line. The ground wire de-icing technology becomes the current problem to be solved. In Shi Bing–Xian Ling Shan 500kV transmission line anti-icing renovation project, according to the complex ground wires, we made deeply study on the DC based de-icing technique for the project and calculated and analyzed. Then we proposed appropriate solutions for de-icing of this project and achieved good effect. This paper based on engineering practice combined with DC based de-icing technology and proposed next prospect.
