Abstract
The utility model relates to a protective tool for an overhead electric power circuit, in particular to a pre-hinged anti-vibration hammer. The utility comprises a wire-clamp body, a steel strand, a big hammer, and a small hammer. The wire-clamp body is fixedly connected with the pre-hinged strand wrapped on the cable. The utility model has a good protective effect and can further enhance the operating quality and service life of the strand, and in addition, the utility model is convenient to install and operate, and is applicable to a wide range of strand diameter.
Description
Technical field
The utility model relates to the protection instrument that a kind of overhead power line is used, and is specially a kind of Pre-Cutter-Type Anti-Vibration Hammer.
Background technology
At present, it mostly is the connected mode that cast steel or cast aluminium clamping plate add the bolt crimping with the cable retained part the domestic stockbridge damper that generally uses, and this connected mode belongs to and is rigidly connected, and is bigger to the lateral pressure of cable, causes stress to concentrate easily and cable damages.
Summary of the invention
It is effective that technical problem to be solved in the utility model provides a kind of protection, and can further improve the running quality of circuit and the Pre-Cutter-Type Anti-Vibration Hammer in life-span.
The utility model is by the following technical solutions: the utility model comprises wire clip body, steel strand wire, and big tup and little tup, wire clip body is fixedlyed connected with the preformed armor rods on cable around the home.
The utility model wire clip body is provided with connecting hole, and wire clip body is fixedlyed connected with preformed armor rods by connecting hole.The utility model wire clip body is provided with the V-type groove, and cable is arranged in the V-type groove on the wire clip body.
Good effect of the present utility model is as follows: the utility model changes the past stockbridge damper and adopts cast steel or cast aluminium clamping plate to add the mode of bolt crimping with the cable retained part; the mode that adopts " V " font cast aluminium wire clip body to combine with preformed armor rods; become and be rigidly connected to flexibly connecting; strengthened the self-damping of cable; and fitting operation is convenient; it is wide to be suitable for wire range, and frequency protection is enough to be dispersed in the 3Hz-120Hz broad frequency range, and four resonance frequencys are arranged in this scope.
