Problems solved by technology

At present, my country's UHV transmission line projects mainly use self-supporting iron towers for overhead power transmission. There are no examples of guyed towers being used in UHV projects in my country, but because guyed towers can save a lot of steel and use them in open and flat areas, they can generate significant economic benefits. benefit, so it has broad application prospects in UHV engineering

Abstract

The invention discloses a basic structure for a V-shaped cable of an UHV single-column cable tower. column, one end of which is embedded in the inclined main column and the other end of which exposes the top surface of the inclined main column. Two stay wires arranged in a V shape are connected between the tower columns. The U-shaped stay wire rod is bent inside the inclined main column. The lower section of the folding line is parallel to the geometric center line of the inclined main column. The planes where the two stay wires are located are parallel. The invention can be used well with the V-shaped cable arrangement structure, not only meets the bearing requirements of UHV cable towers, reduces the number of foundations, but also has a simple type and is easy to implement.

Description

technical field [0001] The invention belongs to the technical field of cable towers for transmission lines, and in particular relates to a basic structure for a V-shaped cable of an ultra-high voltage single-column cable tower. Background technique [0002] UHV transmission lines refer to AC transmission lines with a voltage level of 1000kV and above and DC transmission lines of ±800kV and above. At present, my country's UHV transmission line projects mainly use self-supporting iron towers for overhead power transmission. There are no examples of guyed towers being used in UHV projects in my country, but because guyed towers can save a lot of steel and use them in open and flat areas, they can generate significant economic benefits. Therefore, it has broad application prospects in UHV engineering. [0003] The guyed tower is a special structural type of the transmission line tower, which is generally composed of a tower body composed of a lattice tower column and a tower hea...
