摘　　要：架空输电线路杆塔相序排列变化过程中,容易出现导线相间最小距离不满足规程要求的问题。为了解决此问题,优化杆塔排列,笔者在三维坐标系统中建立一种考虑弧垂及风偏影响的导线斜抛物线数学模型,采用离散值比对算法求解导线相间最小距离。经与传统校核方法进行比较,结果表明,该模型完全实现了规范、快速、精准的校核。实例应用表明,该模型软件是换相档设计的实用工具。In the process of phase sequence arrangement change of overhead transmission line support it is easy to appear the problem that the minimum phase-to-phase spacing of conductors does not meet the requirements of the regulations.In order to solve this problem and optimize the support arrangement a mathematical model of inclined parabola of conductors considering the influence of sag and wind deflection is established in the three-dimensional coordinate system and the discrete value comparison algorithm is used to solve the minimum phase-to-phase spacing of conductors.Compared with the traditional check method the results show that the model fully realizes the standard fast and accurate check.The application example shows that the model software is a practical tool for the phase commutation design.
