An anti-dancing device for single-circuit transmission lines

Abstract

The invention provides an anti-galloping apparatus for a single-circuit power transmission line. The power transmission line comprises a vertically arranged tower body, a tower head transversely arranged at the upper end of the tower body, and a power transmission wire arranged on the tower head; the anti-galloping apparatus comprises a wire anti-galloping mechanism connected with the power transmission wire, an adjusting mechanism arranged on the ground, and a composite insulator module between the wire anti-galloping mechanism and the adjusting mechanism; the wire anti-galloping mechanism comprises regular polygonal frameworks and fixed cable clamps on the peaks of the frameworks; and the adjusting mechanism comprises an unreeling wheel with a steel wire rope, and a foundation arranged at the lower end of the unreelingwheel and a controller connected with the unreelingwheel. The anti-galloping apparatus provided by the invention can satisfy the power grid anti-galloping requirement of wire circuits with relatively large span lengths, and the anti-galloping apparatus has the advantages of good anti-galloping performance, low production cost and convenient installation.

Description

technical field [0001] The invention relates to a technology of electric equipment fittings, in particular, the invention relates to an anti-dancing device for a single-circuit transmission line. Background technique [0002] With the rapid development of power grid scale and the frequent occurrence of severe weather, the frequency of galloping accidents in the power grid has increased significantly, and the degree of harm has increased, causing serious economic losses and social impacts. Galloping can lead to various hazards, including line flashover, tripping, damage to hardware and insulators, broken strands and disconnected wires, and in severe cases, it will lead to the collapse of towers and major power grid accidents. Therefore, it is necessary to provide an anti-galling device for single-circuit transmission lines to prevent galloping of the power grid and ensure stable operation of the transmission line. [0003] The inventor has observed and researched for a long ...

AI Technical Summary

Problems solved by technology

[0003] The inventor has observed and researched for a long time and found that the anti-dancing device adopts interphase spacer rods arranged between adjacent wires, and the interphase spacer rods can play the role of preventing mixed lines. The anti-dance device has the following problems: 1. Between the wires The use of spacer rods cannot effectively suppress the simultaneous galloping of two adjacent conductors, and the effect of preventing grid galloping is poor

2. The structure of the spacer is simple, the anti-dancing performance is poor, and the manufacturing cost is high

3. It has strong limitations, and it cannot play an anti-dance effect for horizontally arranged conductor lines with large spans
