35KV double-loop compound insulation cross arm linear steel pipe pole structure

Abstract

A 35KV double-loop compound insulation cross arm linear steel pipe pole structure comprises a pole body; a second fixing rod is fixedly connected to the pole body; the second fixing rod is connected with a first fixing rod through a detachable connecting mechanism; a compound insulation cross arm is installed at the other end of the first fixing rod; and a wire suspension fitting and a diagonal draw bar are hinged to the other side of the compound insulation cross arm. The diagonal draw bar is connected with a lead double-hanging-point component through an adjusting mechanism capable of being locked, and the lead double-hanging-point component is installed above the pole body. According to the 35KV double-loop compound insulation cross arm linear steel pipe pole structure provided by the invention, the windage yaw distance of the wire suspension fitting is reduced; the compound insulation cross arm is short, the width of a line corridor can be reduced to a large extent, and the installation of the compound insulation cross arm is faster and more convenient.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a 35 kV double-circuit composite insulated cross-arm linear steel pipe pole structure. Background technique [0002] The traditional 35 kV double-circuit line straight steel pipe pole adopts steel cross arm, and the steel cross arm has the following problems: [0003] 1) The steel cross arm is long, and at the same time, it is necessary to install a suspension insulator string to isolate the live line and the tower body. When designing the line, the swing gap of the suspension insulator string should be considered at the same time, which will lead to a wider corridor of the transmission line and take up too much space resource; [0004] 2) The steel cross-arm is connected to the shaft through bolts or flanges, the installation speed is slow, and the installation holes need to be aligned to facilitate the installation of the bolts, which is inconvenient, and it is even...

AI Technical Summary

Problems solved by technology

[0003]1) The steel cross arm is long, and the suspension insulator string must be installed to isolate the live line and the tower body, and the swing gap of the suspension insulator string should be considered when designing the line , which will lead to a wider transmission line corridor and occupy too much space resources;

[0004]2) The steel cross arm is connected to the shaft through bolts or flanges, the installation speed is slow, and the installation holes need to be aligned to facilitate the installation of bolts. It is really inconvenient, and it is even more inconvenient if the work is carried out at high altitude;

[0005]3) In windy weather, the transmission line will shake and cause the crossarm to vibrate, so the bolt connection may be loose, which poses a certain safety hazard
