Wind deflection prevention and wear resistance device for power transmission line

Abstract

The invention relates to the technical field of protection of power transmission and transformation lines, in particular to a wind deflection prevention and wear resistance device for a power transmission line. The wind deflection prevention and wear resistance device comprises an iron tower cross arm, the power transmission line, a cast aluminum sleeve shell and two wind deflection protection mechanisms, wherein the cast aluminum sleeve shell is fixedly mounted on the power transmission line; the upper end of the cast aluminum sleeve shell is connected with a first hanging plate, a hanging ring and a second hanging plate from bottom to top; the upper end of the second hanging plate is perpendicularly suspended on and hinged to the iron tower cross arm; suspension clamps are fixedly mounted at positions, which are located on two sides of the cast aluminum sleeve shell, on the power transmission line; the lower ends of the wind deflection protection mechanisms are fixedly connected to the suspension clamps; included angles are formed between the wind deflection protection mechanisms and the power transmission line in the front-back direction; the upper ends of the wind deflection protection mechanisms are suspended on and hinged to the iron tower cross arm. The wind deflection prevention and wear resistance device is reasonable and compact in structure; by the installation of the wind deflection protection mechanisms, the suspension clamps on the power transmission line are in a relatively stable state under strong wing, so that the amplitude of wind deflection swinging at the position is limited, collision of U-shaped hanging plates of the power transmission line to a cross arm tower material is avoided, and mutual wear between hardware fittings and strand breakage caused by wear of the power transmission line are avoided.

Description

technical field [0001] The invention relates to the technical field of power transmission and transformation line protection, and relates to a windproof and wear-resistant device for power transmission lines. Background technique [0002] Disastrous strong winds have always threatened the safe operation of power grid transmission lines. Accidents such as downed towers, broken lines, wind deflections, insulators coming off strings, and fittings fractures on transmission lines caused by strong winds and sandstorms have occurred from time to time. Especially in strong wind areas, under the action of wind force, the power fittings of power transmission and transformation equipment often collide and wear with their connectors and nearby materials, which may easily lead to wear and tear of power fittings for a long time. At present, there have been many disconnection accidents of transmission lines in strong wind areas due to wear and tear of fittings, which have caused serious ec...

Problems solved by technology

[0003] The invention provides a windproof and wear-resistant device for transmission lines, which overcomes the above-mentioned deficiencies in the prior art, and can effectively solve the problem of U-shaped hanging plates hitting tower materials and wind deflection of transmission lines under the action of strong winds. The impact of the cross-arm of the iron tower causes the wear and tear of the transmission line fittings and the wear and tear of the transmission line.
