Anti-galloping damping device for transmission line

Abstract

The invention provides an anti-galloping damping device for a transmission line. The device comprises a vacuum pipe, a pendant and a cross force transfer block, wherein movable magnetic steel is placed between upper magnetic steel and lower magnetic steel which are fixed in the inner cavity of the vacuum pipe made of a non-magnetic material; the upper magnetic pole and the lower magnetic pole of the movable magnetic steel are the same as the lower magnetic pole of the upper magnetic steel and the upper magnetic pole of the lower magnetic steel; the structure of the pendant is characterized inthat an arc riser is fixedly connected on an open-loop clamp; the structure of the cross force transfer block is characterized in that the lower end of the riser is fixedly connected with a transverse plate, a left baffle and a right baffle are fixedly connected on the transverse plate, and a horizontal shaft is fixed on the upper part of the riser; and the vacuum pipe is clamped in the open-loopclamp of the pendant, the pendant is hung on one end of the horizontal shaft through a hanging hole, and the other end of the horizontal shaft is used for fixing a lead wire or a conductor spacer. The device can prevent the lead wire from swinging left and right and moving up and down, and has the characteristics of simple structure and convenient use.

Description

technical field [0001] The invention relates to an anti-dancing device for a power transmission line, in particular to an anti-dancing shock-absorbing device for preventing the horizontal swing and vertical movement of the transmission line. Background technique [0002] The power transmission line is erected in the field, and it is often affected by the wind to cause shaking and vibration. In some cases, even if it is not a windy day, the vibration will become more and more intense due to resonance, and the amplitude will become larger and larger, eventually causing The transmission line is disconnected, the equipment is damaged, and the normal power transmission is affected. [0003] At present, anti-dancing devices for transmission lines mainly include pre-twisted wires and center-of-gravity hammers, but the anti-dancing effect of pre-twisted wires is poor. If the center of gravity hammer is used, too many will increase the burden on the transmission line, and it is also ...

Problems solved by technology

[0002] The power transmission line is erected in the field, and it is often affected by the wind to cause shaking and vibration. In some cases, even if it is not a windy day, the vibration will become more and more intense due to resonance, and the amplitude will become larger and larger, eventually causing Disconnection of transmission lines, damage to equipment, affecting normal power transmission

[0003] The current anti-dancing devices for transmission lines mainly include pre-twisted wires and center of gravity hammers, etc., but the anti-dancing effect of pre-twisted wires is poor. If the center of gravity hammer is used, too many will increase the burden on the transmission line, which is also a hazard to the transmission line.
