摘　　要：针对大截面导线架空输电线路,从导线柔性出发,分析了传统线形方程的不足,确定了导线最低点水平张力,并对其进行算例验算,肯定了公式的可行性,在没有对导线进行简化的情况下,分析了导线在任一点作用集中荷载时导线的实际线形与弧垂,将此分析与现有的做法进行比较,得到一种全新的计算作用单个集中荷载时的线形算法。In view of large cross-section wire for overhead line. Starting from the wire flexible, by analyzing the deficiencies of the traditional linear equations, calculated axial tension force of the wires＇ lowest point, and in the absence of wire used for the simplified case, lead role any singie concentrated load is analyzed when the conductor is the actual linear and sag. The analysis compared with existing practices, sag after the lead role in a single concentrated load calculation accuracy was improved.
