Improved flexible direct-current transmission line tangent tower
The invention discloses an improved flexible direct-current transmission line tangent tower. The improved flexible direct-current transmission line tangent tower comprises a tower head and a tower body, wherein a left-side grounding electrode wire hanging point and a right-side grounding electrode wire hanging point are arranged on the two sides of the upper part of the tower head correspondingly and used for hanging a grounding electrode wire and a ground wire, the left grounding electrode wire hanging point and the right grounding electrode wire hanging point are correspondingly connected with a metal return wire through an anti-thunder insulator and an anti-icing flashover insulator, the metal return wire is suspended on the left side and the right side at the top of the tower head and is used as a return wire in a normal condition, and the metal return wire is used as the ground wire when the tangent tower is subjected to lightning stroke and discharges lightning. According to the improved flexible direct-current transmission line tangent tower, the metal return wire and the ground wire of the flexible direct-current line tangent tower can be combined, the height of the iron tower is greatly reduced, and the project investment of a flexible direct-current line is reduced.
一种改进型柔性直流输电线路直线塔，包括塔头和塔身,塔头上部的两侧分别设有左侧接地极导线挂点和右侧接地极导线挂点，用于挂设接地极导线和地线，所述左侧接地极导线挂点和右侧接地极导线挂点的挂点处分别通过防雷、防冰闪绝缘子连接金属回流线。所述金属回流线悬垂在塔头顶部的左右两侧，金属回流线在正常情况时，作为回流导线使用；金属回流线在直线塔受到雷击排泄雷电时，作为地线使用。利用本发明建设的直线塔，可将柔性直流线路直线塔的金属回流线与地线合并，大幅降低铁塔高度，降低柔性直流线路工程投资。
