大档距导线风偏抑制的研究与尝试

Study on the Suppress of Wind Deviation of Line Conductor with Large Span

超、特高压输电线路所经过的地区,山区有相当的比例。在这些地区,存在一定数量的较大档距线路段,在运行中发生过大档距导线因大风吹偏,引起导线对边坡放电的故障。文章介绍了这类故障发生的主要原因、相关计算的状况及采取的对策和效果评价。

A significant part of the corridor of UHV transmission line is in mountain area and there are a number of large spans in this area,which is vulnerable to discharge between side phase line and tower due to wind deviation.In this article,the main cause s of discharge and the calculation condition were introduced,the countermeasure as well as effect was evaluated.
