摘要 架空输电线路长期运行在野外,受到各种恶劣自然环境及人类生活生产活动的影响,使得输电线路各部件受到损伤甚至破坏,缩短了使用寿命,进而影响到电网安全。以华东电网输电线路为对象进行了统计,阐述了开展输电线路寿命相关研究的重要性通过对各个部件的关键性评价,说明了导线在输电线路寿命中的重要地位。结合老旧导线的试验分析结果,讨论了影响导线寿命的关键因素。 Overhead transmission lines operated in wild,which is affected by all kinds of adverse natural environment and human activities.All parts of transmission lines are damaged or even destroyed,which could be able to shortening service life and affecting the safety of power grid.This paper takes the transmission line of East China power grid as the object to carry out the statistics,and expounds the importance of performing research on the life of the trans-mission line.Through the critical evaluation of each component,the important role of the conductor in the life of the transmission line is illustrated.According to the analysis results of old AC SR conductors,the key factors affecting the life of the conductors are discussed.
