The utility model discloses a kind of tup combined type composite material stockbridge dampers, including line card, elastic rod and tup, line card is connect with elastic rod by connecting plate, and line card, elastic rod and connecting plate three are in integral structure, inside the embedded tup in the both ends of elastic rod, tup is two, and connecting plate is composite material drawing and extruding plank, and elastic rod is composite material drawing and extruding bar material；Composite material is fibre reinforced composites；For the utility model by using fibre reinforced composites, the ability for solving existing vibration hammer absorption vibrational energy is weak, oxidizable, the problem of resistance to corrosion difference, and eliminates vortex and generate, and reduces circuit energy consumption.
Description
Technical field：
The utility model is related to a kind of for electrical domain, more particularly to a kind of tup combined type composite material stockbridge damper.
Background technology：
Aeolian vibration is very big to the aerial cable especially safety of large span high voltage electricity transmission conductive wire and aging effects, to gentle breeze
The vibration control of the lower aerial cable of excitation can improve the conducting wire service life and prevent line-outage contingency.Vibration control technology is divided into
Passive control and active control, due to the requirement of controller operating position and environment, passive passive control is main at present lead
Line aeolian vibration control method, is implemented as stockbridge damper.
Current existing stockbridge damper is mainly made of metal material, based on steel；Structure type have steel strand wires stockbridge damper,
Damping spring stockbridge damper etc..Although steel shockproof hammer can play a part of vibration control effect, its own damping is small, absorbs
The ability of vibrational energy is weak, oxidizable, and resistance to corrosion is poor, short life, and maintaining is of high cost.Conventional metals stockbridge damper hammer body
Material is cast iron, is easily got rusty；And hammer body has gap, easy ponding accumulated snow to influence damper vibrationproof performance；Wire clamp is using local pressing plate
Clamped design can form closed circuit since clamping plate is metallic conductor, will produce eddy-current loss, increase circuit energy consumption.
Utility model content：
Technical problem to be solved in the utility model is：It overcomes the deficiencies of the prior art and provide a kind of simple in structure, just
In carry, by using fibre reinforced composites, solve existing vibration hammer absorb vibrational energy ability it is weak, it is oxidizable,
The problem of resistance to corrosion difference, and eliminate the tup combined type composite material stockbridge damper that vortex generates.
The technical solution of the utility model is：A kind of tup combined type composite material stockbridge damper, including line card, elastic rod and
Tup, the line card are connect with elastic rod by connecting plate, and the line card, elastic rod and connecting plate three are in integral structure,
The both ends of the elastic rod are embedded in inside the tup, and the tup is two, and the connecting plate is composite material drawing and extruding plate
Material, the elastic rod are composite material drawing and extruding bar material.The composite material is fibre reinforced composites.
The utility model has the beneficial effects that：
1, the utility model solves the energy that existing vibration hammer absorbs vibrational energy by using fibre reinforced composites
Power is weak, oxidizable, the problem of resistance to corrosion difference, and eliminates vortex and generate, and reduces circuit energy consumption.
2, the utility model has used fibre reinforced composites elastic rod, and internal long-chain molecule is when bar vibrates
Triboabsorption energy in large quantities is generated, macro manifestations are to absorb more energy with high-damping in vibration, conducting wire is inhibited to shake
Dynamic effect is more obvious.
3, the utility model has the lower natural frequency of vibration, with the Karman vortex street vortex shedding frequency for blowing air over conducting wire generation
Differ larger, it is not easy to generate resonance.
4, the composite material that the utility model uses has insulating properties, is avoided that near conducting wire, generating vortex increases transmission of electricity
Loss.
5, the utility model has very strong inoxidizability and corrosion resistance, adapts to the severe chemical ring such as coastal area
Border can also improve the service life of stockbridge damper.
6, the utility model has good mechanical performance and resist chemical performance, the cost pole on care and maintenance
It is low, with little need for any later maintenance.
Description of the drawings：
Fig. 1 is the structural schematic diagram of tup combined type composite material stockbridge damper.
Fig. 2 is the left view of Fig. 1.
Specific implementation mode：
Embodiment：Referring to Fig. 1, in figure, 1- line cards, 2- elastic rods, 3- tups, 4- connecting plates.
Tup combined type composite material stockbridge damper, including line card 1, elastic rod 2 and tup 3, line card 1 pass through with elastic rod 2
Connecting plate 4 connects, and line card 1, elastic rod 2 and 4 three of connecting plate are in integral structure, and the both ends of elastic rod 2 are embedded in tup 3
Portion, tup 3 are two, and connecting plate 4 is composite material drawing and extruding plank, and elastic rod 2 is composite material drawing and extruding bar material.Composite material is
Fibre reinforced composites.
In use, since line card 1, elastic rod 2 and 4 three of connecting plate are in integral structure, wire clamp and connecting plate 4 are to elastic rod
The 2 clamping effect of rigidity, collet both sides are substantially independent of each other, and the both ends of elastic rod 2 are embedded in tup 3.
Line card 1 is arranged on conducting wire, under the action of conducting wire and connecting plate 4, tup 3 will up-down vibration, and elastic rod 2
Then alternating bending under the action of alternation moment of flexure, in vibration processes, the structural damping of elastic rod 2 can constantly absorb vibrational energy
Amount so that the amplitude of conducting wire reduces, and achievees the purpose that vibration control.
The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model
Limitation, it is made by the above technical examples according to the technical essence of the present invention it is any it is simple modification, equivalent variations with
Modification, is still within the scope of the technical solutions of the present invention.
