摘要

对2010—2014年中国27个省（市）电网公司的500（330）

50 kV超高压交流架空输电线路的冰害故障及主要缺陷进行了统计、分析

结果显示超高压交流输电线路冰害故障和缺陷主要集中在500 kV输电线路

设计和运维对冰害故障和缺陷的产生影响较大

舞动是冰害故障的主要原因。线路金具最易产生冰害缺陷

冰害故障线路主要集中在投运10年内线路。河南为冰害故障多发地区

冰害故障率总体呈下降趋势。从设计、施工、物资及运维4个方面提出了超高压交流架空输电线路防冰害建议。

Abstract

The faults and defects caused by icing accidents for 500（330）

50 kV AC transmission lines in 27 provincial power grid in China from 2010 to 2014 are figured statistically and analyzed in the paper. The results show that the faults and defects caused by icing accidents focus primarily on 500 kV AC transmission lines. Design and operation

maintenance have great influences on the generation of ice accident faults and defects

and the line galloping is the primary cause of ice accident faults. The overhead power line fittings are easy to generate ice accident defects. The transmission lines which have suffered ice accident faults are focus on the lines which put into operation less than 10 years. Ice accident faults most likely occur in Henan pr

ovince

the failure rate of ice accident for transmission lines is trended down. And the anti-icing measures from four respects such as design

construction

materials and operation

maintenance of EHV AC transmission lines are also proposed in the paper.
