All-round anti-vibration device

Abstract

The invention discloses an anti-vibration device for wires, in particular to a device for preventing wires from vibrating in all directions. A device for preventing wires from vibrating in all directions. The first wire and the second wire are arranged in parallel in the horizontal direction. The first anti-vibration hammer and the second anti-vibration hammer are installed on the first wire, and the third anti-vibration hammer and the second wire are installed on the second wire. For the fourth anti-vibration hammer, a first anti-vibration spring is arranged between the first anti-vibration hammer and the third anti-vibration hammer, a second anti-vibration spring is arranged between the second anti-vibration hammer and the fourth anti-vibration hammer, and the first anti-vibration spring and the The length and structure of the two damping springs are the same, the distance between the clamp splint of the first damping hammer and the clamp splint of the second damping hammer is the same as the length of the first damping spring, and the distance between the third damping hammer and the fourth damping hammer The distance between them is the same as the length of the second damping spring. It has a good effect of preventing conductor vibration and galloping, and has a long service life, which solves the influence of the additional vibration and bending stress of the shockproof device itself on the conductor, and prolongs the service life of the conductor.

Description

technical field [0001] The invention relates to an anti-vibration device for wires, in particular to a device for preventing wires from vibrating in all directions. Background technique [0002] The overhead transmission wire is affected by wind, ice, low temperature and other meteorological conditions, causing the line to vibrate and dance. The vibration frequency is high and the amplitude is small. The wind vibration causes the overhead line to be repeatedly bent at the suspension point, causing material fatigue, and finally leads to broken strands and broken lines. The frequency of galloping is very low, but the amplitude is very large, which can easily cause phase-to-phase flashover, resulting in serious accidents such as line tripping, power failure or burning of wires. In order to solve the above-mentioned problem of wire vibration, the usual solution is to hang an anti-vibration hammer on the high-voltage overhead line wire. When the overhead line vibrates, the anti...

Problems solved by technology

[0003] There are many kinds of anti-vibration hammers at present, but most of them are composed of clamp splints, steel strands and cast iron hammer heads. In severe weather, the external force on the hammer head of the anti-vibration hammer is increased, and there is often a separation between the hammer head and the steel strand, which shortens the service life of the anti-vibration hammer and increases maintenance and replacement operations

[0004] At the same time, because the hammer head of the anti-vibration hammer is affected by external force, the influence of its own additional vibration and bending stress will cause the wire to vibrate in the slightest wind and fluctuate greatly in high winds, which will affect the anti-vibration effect and reduce the service life of the wire
