Problems solved by technology

[0006] In view of this, the present invention proposes an all-inclusive anti-slip type pre-twisted anti-vibration hammer, which aims to solve the problem that the existing anti-vibration hammer tends to slip along the direction of the wire during use, so that the anti-vibration hammer not only fails to achieve its Due to the anti-vibration effect, it will directly affect the normal operation of the transmission line and the service life of the line

Abstract

The invention provides an anti-slip damper with all-clad pre-twisted wires. The damper comprises the all-clad pre-twisted wires winding around a wire, a wire clamp mechanism connected with the wire, and a steel stranded wire with damper heads at both ends. The wire clamp mechanism comprises a clamping part for holding the wire, a fixing part for arranging the steel stranded wire, and a connectingpart for connecting the clamping part and the fixing part. The damper is fixed on the wire through the wire clamp mechanism, and the clamping part of the wire clamp mechanism is provided with the all-clad pre-twisted wires, so that slip of the damper on the wire is restricted, and it is avoided that the damper rotates and slips in the wire direction or the twisting direction of the pre-twisted wires during the long-time use process or under the action of strong vibration.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to an all-inclusive anti-skid pre-twisted anti-vibration hammer for overhead power transmission lines. Background technique [0002] At present, wind vibration is the main form of overhead wire vibration, and it is also the most frequently occurring and most harmful vibration. When the vibration frequency of the overhead wire is high and the amplitude is small, it is easy to cause the overhead wire to bend repeatedly at the suspension point, causing material fatigue, resulting in broken strands and broken wires; when the vibration frequency is low and the amplitude is large, it is easy to cause material fatigue. Lead to serious accidents such as line tripping, power outages or burnt wires, causing huge economic losses to people. Usually, the anti-vibration hammer is suspended at the suspension point of the overhead line, and the energy generated by the vibration of the conduc...
