Description

Damper with damping hammer body structure

Technical Field

The utility model relates to the technical field of damper, in particular to a damper with a damping hammer body structure.

Background

On the high-voltage overhead line, a small hammer is often hung on the wires close to the two sides of the insulator, and the small hammer is called a damper, so that the vibration of the wires due to wind power pulling is reduced. The high-voltage overhead line pole is higher, and the span is great, when the wire receives the wind force effect, can take place the vibration. The operating conditions at the wire suspension are most disadvantageous when the wire vibrates. Due to the multiple vibrations, fatigue failure of the wire occurs due to periodic bending. When the span of the overhead line is greater than 120 meters, a damper is generally adopted for vibration prevention.

The cable is outside the axle center rotation under dead weight and inside oil pressure's effect, still owing to draw the back-twist effect of wire rope itself and cable route about can make the cable produce additional torsion such as different bend simultaneously, consequently the damper of installation can rotate along with the torsion of cable on it, lead to the damper not vertically down, in addition the damper can down move under self gravity, cause damper and cable fastening position to appear becoming flexible, lead to damper to move on the direction, for this reason, we have proposed a damper with damping hammer body structure.
