Technical Field
The invention relates to the field of electric power fittings, in particular to a combined damper for a power transmission line.
Background
The widely used metal accessories of iron or aluminum for the power transmission line are collectively called as hardware fittings. The hardware has a variety of types and uses, for example, various wire clamps for installing wires, various suspension loops for forming insulator strings, various crimping tubes and repairing tubes for connecting wires, various spacers on split wires, and the like, and various stay wire hardware for towers and the size of the protection wires are related and need to be matched with each other. Most hardware fittings need to bear larger pulling force during operation, and some hardware fittings need to ensure good electrical contact at the same time, which is related to the safety of a lead or a tower, and even if one hardware fitting is damaged, a line fault can be caused. Therefore, the quality, the correct use and the installation of the hardware have certain influence on the safe power transmission of the line.
The damper is used for reducing the vibration of the wire caused by wind force. The high-voltage overhead line has high pole position and large span, and can vibrate when the wire is acted by wind. The working conditions at the wire suspension are most unfavourable when the wire vibrates. Due to multiple vibrations, fatigue failure of the wire may occur due to periodic bending. When the span of the overhead line is more than 120 meters, a damper is generally adopted to prevent vibration.
The important part of the anti-vibration hammer is the elastic cross rod, and after the cross rod vibrates for a long time to generate irreversible fatigue damage, the whole anti-vibration hammer loses the effect of reducing wire shaking. Most of the existing damper are designed integrally, are difficult to disassemble and assemble, and can only be replaced integrally once being damaged or losing efficacy, and other undamaged parts can only be replaced together due to incapability of disassembling, so that the maintenance and replacement cost is greatly improved.
