A connection structure of an anti-vibration hammer for overhead transmission lines

Abstract

The invention discloses a quakeproof structure of a conductor, and in particular relates to a connecting structure for a quakeproof hammer of an overhead transmission conductor. The connecting structure for the quakeproof hammer of the overhead transmission conductor has the structure as follows: a first conductor and a second conductor are parallel in the horizontal direction, a first quakeproof hammer and a second quakeproof hammer are mounted on the first conductor, the cable clamp plate of the first quakeproof hammer is connected to a first damping clamp plate through a first damping spring, a third quakeproof hammer is mounted on the second conductor, the cable clamp plate of the third quakeproof hammer is connected to a second damping clamp plate through a second damping spring, and a force transmission spring is formed between the cable clamp plate of the second quakeproof hammer and the cable clamp plate of the third quakeproof hammer. The conductor vibration preventing effect is good, the service life is long, the impact to the conductor from the addition vibration bending stress of the quakeproof device can be prevented with the effect of greatly reducing the vibration of the conductor, the service life of the overhead transmission conductor is effectively improved and the maintenance is convenient.

Description

technical field [0001] The invention relates to a wire shockproof structure, in particular to a connection structure of an overhead power transmission wire shockproof hammer. Background technique [0002] The overhead transmission wire is affected by wind, ice, low temperature and other meteorological conditions, causing the line to vibrate and dance. When vibrating, the frequency is high and the amplitude is small. The wind vibration causes the overhead line to be bent repeatedly at the suspension point, causing material fatigue, and finally leads to broken strands and broken lines. The frequency of galloping is very low, but the amplitude is very large, which can easily cause phase-to-phase flashover, resulting in serious accidents such as line tripping, power failure or burning of wires. In order to solve this problem, a small hammer is often hung on the wire of the high-voltage overhead line. This small hammer is called an anti-vibration hammer. The anti-vibration hamme...

Problems solved by technology

[0003] However, in addition to the breeze vibration of the current overhead line, in some bad weather such as rain, snow and strong wind, the external force on the hammer head of the shockproof hammer is increased, and there is often a separation between the hammerhead and the steel strand, making the shockproof Hammer life shortened, maintenance and replacement work increased

At the same time, because the anti-vibration hammer is affected by external force, the influence of its own additional vibration and bending stress will increase the large galloping of the wire and reduce the service life of the wire

Anti-vibration hammers are less effective at reducing wire gallop
