Overhanging tower of 500 kV compact-type AC power transmission circuit in high-altitude area

Abstract

The invention discloses an overhanging tower of a 500 kV compact-type AC power transmission circuit in a high-altitude area, which comprises a tower body and a tower foot, wherein a cup-shaped structure and an inverted cup-shaped structure are installed successively from top to bottom on the tower body, an upper conducting wire cross arm is disposed on the top end of the cup-shaped structure, a lower conducting wire cross arm is disposed on the bottom end of the inverted cup-shaped structure, and a middle conducting wire cross arm is installed at a joint between the cup-shaped structure and the inverted cup-shaped structure; and ground wire cross arms are disposed symmetrically on two ends of the upper conducting wire cross arm, and side conducting wire cross arms are disposed symmetrically on two ends of the lower conducting wire cross arm. The overhanging tower of the 500 kV compact-type AC power transmission circuit in the high-altitude area disclosed by the invention is simple in structure and rational in design, effectively increased layout density of conducting wires by the unique double-cup structural design, can orderly separate the various kinds of conducting wires and can realize safer and more reliable circuit operation; and in addition, the tower has a light mass, is firmly fixed, and can effectively reduce repairing frequency and workloads of repair workers.

Description

technical field [0001] The invention relates to the field of high-altitude transmission iron towers, in particular to a 500kV compact AC transmission line suspension tower in high-altitude areas. Background technique [0002] At present, some high-altitude and remote areas in my country are far away from the main grid and have not yet been connected to the main grid. They still rely on small water and thermal power to maintain daily production and domestic electricity consumption. Difference. For example, the average distance between counties in Yushu Prefecture is 150 kilometers, all of which are independently powered by small hydropower. However, in winter, the water resources are relatively dry and the power generation is small. The unbalanced power consumption in winter and summer in a year cannot meet the demand for electricity. The problem of power supply structure leads to prominent contradictions between supply and demand. The development of regional power grids lag...
