Branching tower for four-loop overhead transmission line
The invention discloses a branching tower for a four-loop overhead transmission line. A ground wire cross arm set, an upper-layer double-loop wire cross arm set and a lower-layer double-loop wire cross arm set are sequentially arranged on a tower body of the branching tower from top to bottom, the upper-layer double-loop wire cross arm set is provided with three pairs of upper-layer wire cross arms spaced up and down and symmetric about the tower body, the lower-layer double-loop wire cross arm set is provided with three pairs of lower-layer wire cross arms spaced up and down and symmetric about the tower body, and the upper-layer wire cross arms and the lower-layer wire cross arms are staggered around the vertical midline of the tower body clockwise or anticlockwise by 30-60 degrees. Compared with the prior art, mounting structures of T joint branching cross arms are reduced, thus, while the problem of independent branching of two upper-layer loops and two lower-layer loops of the branching tower for the four-loop overhead transmission line is solved, the structure of the same-tower four-loop branching tower is greatly simplified, the tower height and the tower weight of the four-loop branching tower are effectively reduced, and meanwhile the laying cost of the same-tower four-loop overhead line is reduced.
本发明公开了一种四回路架空输电线路用分歧塔，其塔身上由顶部向下依次设有地线横担组、上层双回路导线横担组和下层双回路导线横担组，上层双回路导线横担组设有上下间隔并相对于塔身对称布设的三对上层导线横担，下层双回路导线横担组设有上下间隔并相对于塔身对称布设的三对下层导线横担，上层导线横担与下层导线横担围绕所述塔身的竖直中线顺时针或逆时针的错开30°～60°布设。本发明与现有技术相比，减少了T接分歧横担的安装结构，从而在解决了四回路架空输电线路分歧塔上层两回路与下层两回路独立分歧问题的同时，极大的简化了同塔四回路分歧塔的结构，有效的降低了四回路分歧塔的塔高和塔重，同时降低了同塔四回路架空线路铺设的成本。
