Embodiment 1

[0035] The invention provides a net-type damping wire anti-vibration device, figure 1 It is the structural diagram of the net type damping wire anti-vibration device of the present invention, as figure 1 As shown, a mesh type damping wire anti-vibration device is installed on a power transmission wire. The mesh type damping wire anti-vibration device includes: pre-twisted wire, pre-twisted wire clamp, and mesh structure damping wire;

[0036] One end of the pre-twisted wire clamp is a U-shaped groove structure, and the U-shaped groove is used to be clamped to the transmission wire, the pre-twisted wire passes through the hollow part of the U-shaped groove, and the The other end of the pre-twisted clamp is fixedly connected to the mesh structure damping wire;

[0037] The pre-twisted wire is wound on the power transmission wire.

[0038] The mesh structure damping wire includes: at least two damping wires, and a plurality of compression-type wire clamps;

[0039] The compres...

Abstract

The invention relates to a net-type damping wire anti-vibration device which is installed on a power transmission wire and comprises a pre-twisted wire clamp and a net-type structure damping wire. Oneend of the pre-twisted wire clamp is of a U-shaped groove structure, the U-shaped groove is used for being connected to the power transmission wire in a clamped mode, and the other end of the pre-twisted wire clamp is fixedly connected with the damping wire. According to the technical scheme, damping wire combinations with different lengths and different specifications are adopted, the breeze vibration full-frequency range can be covered, a bolt structure does not exist, and maintenance is not needed in the operation process.

Description

technical field [0001] The invention relates to the technical field of power fittings for power transmission and transformation projects, in particular to a mesh-type damping wire anti-vibration device. Background technique [0002] Breeze vibration is a form of vibration with a high probability of occurrence in overhead transmission lines, and it is easy to cause fatigue and broken strands of ground conductors. It is one of the issues that must be paid attention to in line design and operation. The Bate damping wire + anti-vibration hammer scheme is mostly used for the long-span engineering conductors of transmission lines. Long-term operation experience has proved that the anti-vibration scheme based on damping wires has a better anti-vibration effect. However, this type of anti-vibration solution requires wire stripping at the construction site, and bolts are used to fasten the damping wire clips during high-altitude installation. The installation is difficult, and the bo...
