摘　　要：本文对高压送电线路耐张塔的三维跳线计算建立了详细的数学物理模型,提出了软跳线和硬跳线耐张塔跳线三维计算方法。以500 kV紧凑型线路和±800 kV直流线路耐张塔为例,分别对软跳线和硬跳线耐张塔进行了三维跳线计算。该计算方法可以对跳线进行精确设计,优化塔头布置,节约杆塔造价;将铁塔头部结构布置与电气间隙设计融为一体,实现电气与结构专业在铁塔设计上的无缝衔接;同时实现二维粗略设计向三维精确设计的升级。Establish a detailed mathematical model to three-dimensional jumper Calculation of High-voltage transmission line tension tower,made of soft and hard jumper dimensional calculation method.For example,respectively calculation soft and hard jumper to 500 kV compact line and±800 kV DC line tension towers.The method can design the jumper accurately,optimize the layout of the tower head,and save the tower cost.The structural layout of the tower head and the electrical clearance design are integrated to realize the seamless connection between the electrical and structural majors in the tower design.At the same time,the upgrade from two-dimensional rough design to three-dimensional precise design is realized.
