对500kV二自线(凉山段)间隔棒的探讨

Discussion on Circuit Interval Stick

为避免四分裂及以上导线发生舞动,通常采用安装相间矩形间隔棒的方法进行消除。但对高海拔、重冰区段线路来说,安装相间矩形间隔棒效果不是很好,矩形间隔棒变形、损坏、甚至断裂的现象时有发生,严重威胁着线路安全运行。本文结合500kV二自线凉山段进口加拿大4型间隔棒实际使用情况,对高海拔、重冰区线路间隔棒进行了一些分析探索。

Alternative rectangular circuit interval stick is often installed to avoid the wave of wire.However,it can't work very well when installing alternative rectangular circuit interval stick in the regions with a high elevation and cover with heavy ice because rectangular circuit interval stick is prone to deformity,damage and even break,so it's disadvantaged for safe operation of circuit.In the light of the actual using conditions on TypeⅣcircuit interval stick imported from Canada,some analysis and exploration on circuit interval stick in the regions with a high ele- vation and cover with heavy ice have been made in this article.
