摘要
针对近年来发生的由覆冰引起的倒塔断线、冰闪及舞动等冰害事故,对几种不同冰害事故分析了其形成过程及特点。并从自然气象条件和设计等方面分析了冰害事故发生的原因。结合冰害事故都是由覆冰引起这一特点,分析了覆冰的形成机理及影响覆冰的因素,从设计和运行维护上提出了防治冰害事故的措施。
According to the faults caused by ice accretion happened in recent years, inehding tower falling down, icing flashover of insulator and swing of conductor, the characteristics of the ice faults were fully discussed in this paper. In terms of the atmospheric condition and line design, the reasons causing the faults were analyzed. The mechanism of ice accretion and the influencing factors to ice accretion were also analyzed, and then some preventive measures were put forward.
