摘要
在介绍导线覆冰的形成、分类及其影响因素的基础上,重点分析了气象条件(包括温度、风速和风向)对导线覆冰的影响。另外,还分析了导线覆冰对导线安全的影响,即导线覆冰对导线负载的影响、覆冰厚度增加时对导线强度的影响,为输电线路设计及安全提供参考。
On the base of introdnction of formation, classification and effect on the conductor ice coating, this paper stressed the influence of meteorological condition on conductor ice coating, which included temperature, wind velocity and wind direction. It also analysed the influence of conductor ice coating on conductor security, including the influence of ice coating on load and ice rising on line intensity. This paper gives a reference to design and security of overhead transmission lines.
