Dianci bileiqi为探究输电线路绝缘子风偏特性，搭建了某地区500 kV输电线路4档耐张段输电杆塔-串-线耦合有限元模型，分别对直线塔悬垂绝缘子串和耐张塔跳线绝缘子串进行了稳态风况与脉动风况的风偏角计算。稳态风速设置为该地区雷电过电压工况（15 m/s）、操作过电压工况（20 m/s）、大风工况（35 m/s），分析了临界风速下档距、高差和风攻角对直线塔悬垂绝缘子风偏角的影响以及串长和风攻角对耐张塔跳线绝缘子风偏角的影响，并结合平均风速为35 m/s的脉动风况与不同降雨强度对该线路进行了脉动风偏响应分析 ...

Jianzhu Gangjiegou Jinzhan下击暴流作为一种局部强对流天气，是导致输电塔发生破坏的主要原因之一。为研究输电塔在下击暴流作用下的相关参数对输电塔风振系数的影响和等效静力风荷载分布，首先建立输电塔有限元模型并进行动力特性分析：建立冲击射流风场模型获取平均风速时程，使用谐波合成法模拟脉动风速时程，叠加得到下击暴流总风速时程；采用频域方法分析结构阻尼比、峰值因子以及脉动风速谱类型等参数对输电塔风振系数的影响程度及规律。然后，介绍并利用三种不同等效静力风荷载计算方法分析输电塔在下击暴流作用下的等效静力风荷载分布 ...
