Problems solved by technology

[0004] Based on this, it is necessary to provide a guy tower with a compact structure and less prone to phase-to-phase flashover in windy conditions because the structure of the guyed tower is not compact enough and prone to phase-to-phase flashover in the case of wind deflection

Abstract

The invention relates to a guyed tower. The guyed tower comprises a first tower body, a second tower body and a cross arm assembly; the second tower body and the first tower body are arranged at a certain interval in the first direction; the cross arm assembly is used for hanging a wire, is connected between the first tower body and the second tower body, and comprises a plurality of insulators which are connected with one another; and the cross arm assembly is symmetrical with a virtual axis as a symmetry axis, and the cross arm assembly, the first tower body and the second tower body jointlydefine at least two triangles. According to the guyed tower, based on the characteristic that the symmetrical structure and the triangular structure have high stability, the cross arm assembly has good structural stability, arrangement of the wires on the guyed tower is more stable, the windage yaw flashover problem of interphase wires is solved under the condition that the width of a power transmission line corridor is greatly reduced, and the transmission efficiency of the line is improved.

Description

technical field [0001] The invention relates to the technical field of power transmission lines, in particular to a cable tower. Background technique [0002] With the progress of society and the improvement of scientific and technological level, the construction of power grid is also developing rapidly. As a supporting structure for supporting wires and lightning protection wires in overhead transmission lines, the guy tower can make the wires meet the distance limit requirements to the ground and ground objects, and can bear the loads of the wires, lightning protection wires and their own loads and external loads. play an important role. [0003] The wires of traditional guyed towers are arranged horizontally, and suspension insulator strings are required to hoist the wires. Therefore, the corridor width is wide, the weight of the tower body is heavy, the construction cost is high, and phase-to-phase flashover is prone to occur in the case of wind deflection. Therefore, ...
