摘要
以750 kV白-黄II回输电线路导线跳股现象为例,通过对扩径导线结构及关键架设技术特点的分析找出扩径导线跳股原因,提出了扩径导线在设计、加工制造、施工方法等方面的具体建议。分析结果表明:加工工艺和施工方法的改进,可以有效预防导线跳股现象的发生。
As an example of the section distortion of power line in 750 kV double loop power trans- mission lines from Baiyin to Huanghe, by analyzing the structure of extended diameter line,finds out the causes of the section distortion of extended diameter line, bring forward the concrete suggestions from design, manufacture and construction method of extended diameter line. The analysis resuk shows that the improving of manufacture technics and construction method may prevent effectively phenomenon of section distortion of power line.
