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。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.
