摘　　要：近年来发生的由输电线路覆冰引起的倒塔断线、冰闪及舞动等冰害事故造成了巨大的经济损失,威胁电力系统的安全可靠运行。本文分析了输电线路冰害的原因和特点,从设计、运行维护及电缆、绝缘子、杆塔的抗冰雪技术上提出了防治冰害事故的措施,提高电网抗击严重自然灾害的能力。In recent years, line broken, ice flashover and galloping caused by transmission line icing brought huge economic loss. And it also threatens the safety and reliability of power system. This paper analyzes the causes and characteristics of transmission line ice damage, puts forward the prevention measures against ice damage in design, operation and the anti ice technology of cable, tower and insulators. These will improve the ability of power grid in the fight against serious natural disasters.
