紧凑型直线塔V型绝缘子串受力分析

Force Analysis of V-type Insulator String on Compact Linear Tower

介绍了V型绝缘子串悬挂方式及受力分析。以500kV某输电线路工程为例,用工程简化和理论方法来阐述V型绝缘子串的计算方法。计算结果表明:理论方法在铁塔横担上及短腿腿部斜材的选材稍大些;塔身的选材上两者差别不大。

This artical introduced the suspension mode and force analysis of V-type insulator string. Took a 500 kV transmission line project as example, engineering simplified method and theory were respectively used to the calculation of V-type insulator strings. Results show that the theory method have slightly larger margin on the material selection of tower crossarm and diagonal part of the shot leg, have little difference on tower selection.
