Problems solved by technology

[0002] Existing overhead transmission lines can be divided into long-term lines and temporary transition lines according to the operation period. The operation period of temporary transition lines is usually 3-12 months, which is mainly used to adjust the construction sequence of related transmission lines. Traditional temporary transition lines usually use High-cost angle steel and steel pipe towers are constructed on-site, resulting in high construction costs and long periods of time

Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0026] Refer to attached Figure 1-2 , this embodiment includes a three-link body, the three-link body is fixed on the ground through a chassis 4, and the three-link body includes outer corner bars 1, middle bars 2 and inner corner bars 3 arranged in a straight line at a certain distance. The outer corner bar 1, the middle bar 2 and the inner corner bar 3 are all made of multi-section prestressed reinforced concrete bar sections 5. The outer corner bar 1 and the inner corner bar 3 have the same structure, and are symmetrically arranged around the center bar 2, wherein the outer corner bar 1 is arranged outside the corner of the line, and the inner corner bar 3 is arranged inside the corner of the line.

[0027] The lower ends of the outer corner bar 1 , middle bar 2 and inner corner bar 3 are respectively buried in the soil through the chassi...

Abstract

A triple rod of a power transmission transition line comprises a triple rod body, the triple rod body is fixed to the ground through a bottom plate at the bottom and a pull wire on the side face, thetriple rod body comprises an outer angle rod, a middle rod and an inner angle rod which are sequentially and linearly arranged, and the outer angle rod and the inner angle rod are the same in structure and are symmetrically arranged with the middle rod as the center. A ground wire and stay wire hoop I, a jumper wire string suspender hoop I and a wire and stay wire hoop I are respectively arrangedon the outer ring of the outer angle rod from top to bottom; the outer ring of the middle rod is provided with a jumper string suspender hoop II, a wire and a stay wire hoop II from top to bottom; a ground wire and stay wire hoop II, a jumper wire string suspender hoop III and a wire and stay wire hoop III are arranged on the outer ring of the inner angle rod from top to bottom. The structure is simple, components are all prefabricated parts, on-site assembly is rapid, safe and reliable, and the triple rod can be suitable for corners and terminal poles of power transmission lines with the voltage class of 220 kV or below.

Description

technical field [0001] The invention relates to a power transmission line, in particular to a three-linkage of a power transmission transition line. Background technique [0002] Existing overhead transmission lines can be divided into long-term lines and temporary transition lines according to the operation period. The operation period of temporary transition lines is usually 3-12 months, which is mainly used to adjust the construction sequence of related transmission lines. Traditional temporary transition lines usually use High-cost angle steel and steel pipe towers are constructed on-site, resulting in high construction costs and long periods. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a three-link power transmission transition line with simple structure, quick assembly, safety and reliability. [0004] The technical solution adopted by the present inventio...
