| 摘 要： | 根据斜抛物线理论和三维坐标转换技术,建立了进线档导线相间距离的三维精确校验模型,通过编制三维CAD交互式相间距离计算软件,提出了采用双回路塔和四回路塔的双层构架典型出线方案,并对控制进线档相间距离的导线自荷重及张力、进线档档距和高差等敏感因素进行了分析,最后提出了进线档档距、导线张力和构架相间距离的设计建议.

| Abstract: | According to the inclined parabola theory and 3D space transformation technology,the 3D precise methods on how to determine the phase-to-phase spacing are established.Subsequently,by means of the 3D CAD interactive software,the outgoing line schemes of the double layer framework are proposed.At the same time,the sensitive factors which affecting the phase-to-phase spacing are analyzed.At last,several suggestions on how to design the approach span,wire tension and frame distance are proposed. |
