Description

Tuning fork type damper

Technical Field

The utility model relates to an electric power fitting technical field, concretely relates to tuning fork formula damper.

Background

Vibration of overhead power and lightning conductors and overhead fiber optic lines is a periodic oscillation in the vertical plane caused by wind and creates a series of standing waves of modest amplitude throughout the span. Long-term vibration of the wire can cause additional mechanical stress to the wire material, causing the wire to fatigue and break over time. The vibration of the wire threatens the safe operation of the line greatly, and not only causes the breakage of the wire, but also can lead the steel feet of the insulator to loosen and fall off, wear hardware fittings and even cause the damage of the tower. An effective method for eliminating the vibration of the lead is to install an anti-vibration hammer on the lead. When the wire vibrates, the vibration energy of the wire is absorbed by the relative movement of the damper, so that the vibration of the wire is reduced and eliminated. The various damper has certain natural frequency and vibration-proof performance according to different structures, weights and geometric dimensions.

Among the prior art, the stockbridge damper one end is passed through bolted connection to the wire line, and wherein connect comparatively loaded down with trivial details, under the high altitude construction condition, too loaded down with trivial details operation leads to higher operation danger easily.
