摘　　要：随着全球大气候的变化,中国极端风雪天气愈加频繁,架空输电线路导线舞动时常发生,往往会引起线路跳闸,电弧烧伤,金具、绝缘子损坏,导线断股、断线,倒塔等严重事故,造成巨大的经济损失。因而,对高压架空输电线路舞动区的研究与划分显得尤为重要。笔者对1 000 kV线路进行了全线的实地调研,并且搜集了大量线路经过地区的气象资料,在分析了舞动区基本理论的基础上,结合线路经过地区的地形地貌和气象条件,对该线路进行了舞动区的划分,希望对运行单位更高效的开展运行维护管理提供一定的帮助和指导。With global climate changed,extreme weather with rain and snow appears much more frequently in China,and the galloping of transmission lines which is easy to tend to evoke the nasty accident of inter-phase short-circuiting,conductor burned,hold down towers,and conductor broken appears frequently too,which cause huge economic loss.Thus,the study and divide of the high voltage overhead transmission lines’ galloping region appears particularly important.Members of the research group made a field survey on the whole 1 000 kV lines,and gathered a lot of meteorology date of the line through areas.We divide the galloping region of this 1 000 kV line,based on the analysis of the basic theory of galloping region and combined with the topography and meteorological conditions of area which line across,wants to provide some help and guidance to the operating unit to carry out more efficient operation and maintenance management.
