摘　　要：分析了由于直线跨越塔悬垂绝缘子串倾斜,引起耐张段内档距重构的现象,建立了计算模型,并推导出大跨越地面紧线情况下割线长度的计算方法。经实践验证,该模型具有较高的计算精度。The span reconstruction in the strain section is analyzed in this paper, which is caused by the inclination of suspension insulator strings in tangent tower, and then the calculation model is established. The calculation method of conductor removed-length is derived under the condition of large-span ground-tensioning. It is verified by practices that this model has higher calculation accuracy.
