高压架空输电线路覆冰问题研究

Research on Icing Problem of High Voltage Overhead Transmission Lines

介绍高压输电线路覆冰的种类、形成机理及影响覆冰的因素,分析输电线路冰害事故的成因和线路覆冰的主要危害。阐述融冰技术的研究现状和防冰除冰的主要方法,指出存在的问题并提出改进措施,以期为预防输电线路冰灾提供参考。

This paper introduces the formation mechanism of icing in high-voltage transmission line, as well as the types and the influ- ence factors of icing. The author analyzes the causes of icing damage in transmission line, discusses the main hazard caused by the icing line, and examines the current research situation of iee melting technology and the main methods of anti-icing and deicing. Accordingly, improvement measures are proposed.
