Power line vibration absorber

Abstract

The invention relates to a power line vibration absorber which mainly comprises a vibration absorbing rod, sensing barrels and a connecting rod. The connecting rod rotatably sleeves a fixed rotating shaft which is mounted on a pole tower, one end of the connecting rod sleeves a cable in an annular fastening manner while the other end of the same is fixedly connected with the vibration absorbing rod which is made by a permanent magnetic material, a magnetic field of the permanent magnetic material is parallel to axis of the vibration absorbing rod, the vibration absorbing rod is perpendicular to a plane where the connecting rod and the cable are positioned, the sensing barrels are arranged at two ends of the vibration absorbing rod in a sleeved manner, the two ends of the vibration absorbing rod are not exposed out of the sensing barrels respectively, the vibration absorbing rod does not contact with each sensing barrel, and each sensing barrel is a cluster of coaxial closed coils and is fixedly mounted on the pole tower. The power line vibration absorber can effectively reduce vibration transmitted to the pole tower by the cable, so that loosening of screws of the pole tower is prevented effectively; wear between the cable and the pole tower is reduced, and service life of each of the cable and the pole tower is prolonged.

Description

technical field [0001] The invention relates to a power line accessory, in particular to a power line vibration damper. Background technique [0002] In order to realize efficient and simple long-distance power transmission, overhead wires are commonly used at present; overhead wires support cables at a certain height through towers, so as to realize wiring in the air; this wiring method will not affect ground traffic The cable is buried underground to save time and effort; because the cable itself is heavy, it is necessary to build a tower within a certain span; because the cable is erected at a high altitude, the high-altitude wind is strong, and the cable swings back and forth under the action of the wind. After being transmitted to the tower, it will drive the tower to vibrate. This vibration will cause the relative displacement between the screw and the screw hole on the tower. The wear and tear of the connection between the cable and the tower greatly reduces the serv...

After being transmitted to the tower, it will drive the tower to vibrate. This vibration will cause the relative displacement between the screw and the screw hole on the tower. The wear and tear of the connection between the cable and the tower greatly reduces the service life of the cable; in the case of strong winds, the cable is prone to breakage at the worn part, causing danger
