摘    要:以拉线塔中线绝缘子串为分析对象, 通过对横担、拉线铅锤面间的距离分析, 再将绝缘子的串长、角度, 导线风偏角、弧垂投影至拉线铅锤面, 在拉线铅锤面建立中线绝缘子串的轨迹方程, 以带电体与拉线间的距离为限制条件, 从不同角度计算出第1、2、3 极限风偏角, 取其中的最小值为极限风偏角。极限风偏角的确定为设计和施工中校核水平、垂直荷载之比提供了依据。

关 键 词:拉线塔  中线绝缘子串  极限风偏角  计算

Abstract:Using guyed tower middle line insulator string as an object, through analyzing of distance between cross arm and boom guy plumb plane, and projecting insulator string length, angle, conductor wind inclined angle, and sag to boom guy plumb plane, middle line insulator string tracking equations can be established. Using the distance between charged body and guy as a constraint condition, the first, second, and third limit wind inclined angles can be calculated from different angles, and the minimum one is chosen as the limit wind inclined angle. The determination of limit wind inclined angle provides basis for horizontal and vertical load ratio checking in design and construction.
Keywords:guyed tower  middle line insulator string  limit wind inclined angle  calculation
