Basic structure for extra-high-voltage single-column guyed tower V-shaped stayguys

Abstract

The invention discloses a basic structure for extra-high-voltage single-column guyed tower V-shaped stayguys. The basic structure comprises stayguys, a tower column connected by the stayguys, and a plurality of basic structure main bodies, wherein each basic structure main body comprises a base plate, an inclined main column fixed on the top surface of the base plate, a U-shaped stayguy rod of which one end is embedded into the inclined main column and the other end is exposed out of the top surface of the inclined main column, and a triangular connecting plate fixed on the exposed end of the U-shaped stayguy rod, the stayguys are fixed on the triangular connecting plate, two stayguys are arranged between each basic structure main body and the tower column in a V shape, the U-shaped stayguy rod is bent in the inclined main column, a bending line of the lower section is parallel to a geometric center line of the inclined main column, and a bending line of the upper section is parallel to a plane on which the two stayguys on the basic structure main body are positioned. The basic structure can be preferably matched with a V-shaped stayguy arrangement structure, the bearing requirement of an extra-high-voltage guyed tower can be satisfied, the quantity of foundations is reduced, the form is simple, and the basic structure is easy to realize.

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...
