Description
Technical field：
The utility model relates to a kind of for electrical domain, more particularly to a kind of advanced fiber reinforced composites stockbridge damper.
Background technique：
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
Motivating the vibration control of lower aerial cable can be improved the conducting wire service life and prevents 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, and the service life is short, and maintenance is at 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 influences damper vibrationproof performance；Wire clamp is using local pressing plate
Clamped design can form closed circuit since clamping plate is metallic conductor, can generate eddy-current loss, increase route energy consumption.
Utility model content：
Technical problem to be solved in the utility model is：It is simple, just to overcome the deficiencies of the prior art and provide a kind of structure
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 advanced fiber reinforced composites stockbridge damper that vortex generates.
The technical solution of the utility model is：A kind of advanced fiber reinforced composites stockbridge damper, including line card and tup,
The tup is two, and the both ends of elastic rod are arranged in, and it is one that the intermediate position of the elastic rod, which is provided with the line card,
The connecting plate of body structure, the connecting plate are composite material drawing and extruding plate, and the elastic rod is composite material drawing and extruding bar material, described
Tup is the complex of structural steel and composite material.
The tup and the elastic rod coupling part are composite material.The tup is with the elastic rod coupling part
Structural steel.The tup is the structural steel that outer layer covers have composite 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 route 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 in vibration with high-damping, inhibit conducting wire vibration
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, the material of tup is the complex of structural steel and composite material, this is to increase tup quality using the high density of steel, is increased
The vibration control ability of strong stockbridge damper.
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, hardly need any later maintenance.
Detailed description of the invention：
Fig. 1 is the structural schematic diagram of advanced fiber reinforced composites stockbridge damper.
Fig. 2 is the left view of Fig. 1.
Specific embodiment：
Embodiment：Referring to Fig. 1 and Fig. 2, in figure, 1- line card, 2- elastic rod, 3- tup, 4- connecting plate.
Advanced fiber reinforced composites stockbridge damper, including line card 1 and tup 3, tup 3 is two, and is arranged in elasticity
The both ends of bar 2, the intermediate position of elastic rod 2 are provided with the connecting plate 4 being structure as a whole with line card 1, and connecting plate 4 is composite material
Pultrusion plate, elastic rod 2 are composite material drawing and extruding bar material, and tup 3 is the complex of structural steel and composite material.
Tup 3 and 2 coupling part of elastic rod are composite material.Tup 3 and 2 coupling part of elastic rod are structural steel.
Tup 3 is the structural steel that outer layer covers have composite material.Composite material is fibre reinforced composites.
In use, since wire clamp and connecting plate 4 are to the clamping effect of the rigidity of elastic rod 2, the substantially mutual not shadow in collet two sides
It rings, line card 1 is arranged on conducting wire, and under the action of conducting wire and connecting plate 4, tup 3 will be vibrated up and down, and elastic rod 2 then exists
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,
So that the amplitude of conducting wire reduces, achieve 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.
