Arched overhanging tangent tower on +/-800kV extra-high voltage direct current transmission line
The invention provides an arched overhanging tangent tower on a +/-800kV extra-high voltage direct current transmission line. The arched overhanging tangent tower comprises a ground wire support, a wire cross arm, a tower body and tower legs; the wire cross arm is arranged on the top of the tower body and composed of two cross arm branches symmetrically extending towards the two sides of a tower head, the positions of the two cross arm branches are symmetrical about the central axis of the tower body, wire hanging points used for installing insulator strings are arranged at the two ends of the cross arm branches, and bipolar transmission wires are hung through the insulator strings; the ground wire support is arranged on the top of the wire cross arm and composed of two support branches symmetrically extending towards the two sides of the tower head, the positions of the two support branches are symmetrical about the central axis of the tower body, and ground wire hanging points used for hanging ground wires are arranged at the ends of the two support branches; and the two cross arm branches of the wire cross arm are each composed of a trapezoid inner cross arm and a trapezoid outer cross arm, and the trapezoid inner cross arms and the trapezoid outer cross arms meet the requirement for electrical clearance. The length and the pole spacing of the cross arm can be reduced, the effective height of the iron tower is increased, and the weight of the iron tower is reduced.
一种±800kV特高压直流输电线路上拱形悬垂直线塔，包括地线支架、导线横担、塔身和塔腿；导线横担设置在塔身的顶部，导线横担由对称向塔头两侧伸展的两个横担分支组成，两个横担分支的位置关于塔身中轴线对称，横担分支的两端设有用于安装绝缘子串的导线挂点，通过绝缘子串悬挂两极输电导线；地线支架设置在导线横担的顶部，地线支架由对称向塔头两侧伸展的两个支架分支组成，两个支架分支的位置关于塔身中轴线对称，两个支架分支的端部设置用于悬挂地线的地线挂点；导线横担的两个横担分支均由梯形内横担和梯形外横担组成，由梯形内横担和梯形外横担满足电气间隙。本发明能够缩短横担长度及极间距，增加铁塔的有效高度，降低铁塔重量。
