An anti-dancing device for single-circuit transmission lines

Abstract

The invention provides an anti-galloping device for a single-loop power transmission line. The power transmission line comprises a tower body, a tower head and a transmission conductor, wherein the tower body is vertically arranged; the tower head is transversely arranged at the upper end of the tower body; the transmission conductor is arranged on the tower head; the anti-galloping device comprises conductor anti-galloping mechanisms, an adjusting mechanism and composite insulator assemblies; the conductor anti-galloping mechanisms are connected with the transmission conductor; the adjusting mechanism is arranged on the ground; and the composite insulator assemblies are arranged between the conductor anti-galloping mechanisms and between the conductor anti-galloping mechanisms and the adjusting mechanism respectively. A stabilizing device provided by the invention can meet the anti-galloping requirements of a power grid of a conductor line with a relatively large span, and has the advantages of being good in anti-galloping property, low in production cost and convenient to install.

Description

Technical field [0001] The present invention relates to a technology of power equipment fittings, in particular, the present invention relates to an anti-galloping device for a single-circuit transmission line. Background technique [0002] With the rapid development of power grid scale and the frequent appearance of bad 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 cause many hazards, including line flashover, tripping, damage to fittings and insulators, wire breakage and wire breakage. In severe cases, it can cause towers to collapse and cause major grid accidents. Therefore, it is necessary to provide an anti-galloping device for a single-circuit transmission line to prevent the grid from galloping and ensure the stable operation of the transmission line. [0003] After long-term observation and research, the inventor found that ...

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 vertically arranged conductor lines with large spans
