Description

Damper

Technical field

The utility model relates to electric power fixture technology fields, in particular to a kind of damper.

Background technique

On high voltage overhead lines road, a hand hammer is often hung on the conducting wire of insulator two sides, this hand hammer is damper. Damper is to reduce conducting wire because wind-force heaves out vibration and set.High-tension overhead line bar position is higher, and span is larger, when leading When line is acted on by wind-force, it may occur that vibration.When conductor vibration, the operating condition at conducting wire suspension is the most unfavorable.Due to multiple Because of periodically bending fatigue rupture can occur for vibration, conducting wire.When overhead transmission line span is greater than 120 meters, vibrationproof is generally used Hammer vibrationproof into shape.

Currently, the damper of high voltage overhead lines road installing is after being used for a while, due to by natural environment or spiral shell The clamp effect of the influence that bolt is not tightened, damper can be deteriorated, and be easy to appear the phenomenon that damper deviates installation site, be commonly called as " sliding to run ".If handled not in time, damper will not have the effect of vibrationproof, can also reinforce sometimes after " sliding to run " phenomenon occurs The vibration of high voltage overhead lines road conducting wire, it will threaten the safe operation of route.Vibrationproof is handled in the maintenance work of route Hammer " sliding to run ", the operation mode generallyd use has two kinds：1. application has a power failure, power failure operation is carried out；2. carrying out electrification defect elimination.So And either have a power failure or charge defect elimination, all considerably increase the cost of power grid operation management and the risk of manual work.
