500kv Single-loop Wine Cup Type Linear Tower with Large Span Length Used in High Altitude Area

Abstract

The invention relates to a 500kv single-loop wine cup type linear tower with large span length used in high altitude area, which includes a tower head and a tower body, wherein the tower head is arranged on the top of the tower body; the tower head includes a cross arm and a tower head connecting part, the tower head connecting part adopts two, and the two tower head connecting parts are arrangedat the lower part of the cross arm and are arranged in parallel; the top of the tower body adopts a V-shaped structure and is connected with the two tower head connecting parts. According to the invention, the height of the tower head can be reduced, the weight of the iron tower can be reduced, the comprehensive cost of the iron tower is reduced, the operation reliability is improved, and meanwhile, the hoisting and construction risk of the tower head rod material of the iron tower is reduced; it can be applied in the condition of high altitude area (altitude of 4000-50000m) and span length of1600m-1800m.

Description

technical field [0001] The present invention relates to a single-circuit linear tower, in particular to a single-circuit wine glass-type linear tower with an extra large span of 500kV in high-altitude areas (4000-5000m above sea level) and a span of 1600m-1800m. . Background technique [0002] In the design of 500kV transmission line towers in high-altitude areas, it is necessary to pay attention to the adjustment of the electrical clearance of the conductors and the topography and topography conditions of large spans and large height differences. Therefore, it is necessary to design a high-altitude area 500kV single-circuit wine glass type extra large span linear tower. [0003] At present, the straight-line towers with single-circuit extra-large spans on domestic lines adopt the arrangement of cat-tower towers, and the conductors are arranged in a triangle. This kind of iron tower has a large head height, poor lightning protection performance, relatively complicated forc...

AI Technical Summary

Problems solved by technology

This kind of iron tower has a large head height, poor lightning protection performance, relatively complicated force, heavy weight of the iron tower, and high engineering cost

At the same time, due to the poor topography of the tower in high-altitude mountainous areas and the harsh climate environment, it is difficult to assemble and construct the iron tower, and the height of the cat-head tower head is relatively high, which increases the risk of hoisting and assembling the tower head rods
