Description

A kind of Combined shock-proof hammer protects lines

Technical field

The utility model belongs to the vibration absorber field of transmission line, is specifically related to a kind of Combined shock-proof hammer and protects lines.

Background technology

Along with the development of China's power industry, conveying capacitance significantly increases.The effect of the meteorological conditions such as overhead power line wind-engaging, ice, low temperature, makes circuit produce vibration and wave.Vibration frequency is higher and amplitude is very little, and wind vibration makes overhead wire at suspension point place repeatedly by stubborn folding, causes fatigue of materials, finally causes disconnected stock, line-outage contingency.The frequency of waving is very low, and amplitude is very large, is easy to cause alternate flashover, causes the serious accidents such as line tripping, power failure or burn wire.Stockbridge damper, to absorb or damping vibration energy, is eliminated the resonance that circuit self-vibration and elimination wind etc. cause, is changed circuit wobble frequency, prevent the vibration of circuit or wave.

Protect lines, the rigidity of cable mounting points can be strengthened, disperse concentrated stress simultaneously, good to the protective value of optical cable.On transmission line optical cable, when using screw bolt-type stockbridge damper, in order to avoid damaging fiber unit during bolt tightening, supporting the use one group when a general stockbridge damper is installed and protecting lines.

Such as the patent No. is the utility model of ZL 201120514471.6, and name is called " stockbridge damper for heavy in section high-voltage conducting wires ", relates to the stockbridge damper of a kind of heavy in section high-voltage conducting wires.By aluminium alloy wire chuck, protect lines, steel strand wire and ceramic tup and form, wire clamp head upper end is provided with protects lines, protects in lines and has wire, and wire clamp head lower end is provided with steel strand wire, and the two ends of steel strand wire are provided with tup, and wire clamp head is also provided with fastening bolt.

And in the line due to the difference of span, may need to install multiple stockbridge damper by same span, corresponding also need to install many groups and protect lines, construction trouble, and be unfavorable for circuit vibrationproof and anticorona.

Utility model content

The utility model object is to provide a kind of Combined shock-proof hammer to protect lines, multiple stockbridge dampers that this Combined shock-proof hammer protects lines are arranged on whole piece and protect on line, install simple and convenient, compact conformation is flexible, wider concentrated stress when having disperseed bolt tightening, strengthen the rigidity of cable mounting points, strengthen the vibrationproof performance and anticorona ability of protecting lines, solve a stockbridge damper in prior art and one group of troublesome problem of construction of protecting lines and bringing is installed.

This Combined shock-proof hammer protects lines and is achieved by the following technical solution:

A kind of Combined shock-proof hammer protects lines, the described lines that protect comprise and protect line and stockbridge damper, the described steel wire protecting line and comprise outside coated aluminium lamination, described stockbridge damper is in the font of falling T, the tup that described stockbridge damper comprises the wire clamp of the described font of falling T vertical portion, the Support Level vertical with described vertical portion and is connected in Support Level, the number of described stockbridge damper is more than or equal to two.

Further, the steel wire of the coated aluminium lamination in described outside is strand helical structure processed.

Further, the strand of the steel wire of the coated aluminium lamination in described outside is twisted to contrary to cable outer layer.

Further, the steel wire both ends of the coated aluminium lamination in described outside are hemisphere.

Further, the steel wire close-packed arrays of the coated aluminium lamination in described outside covers whole cable outer layer.

Further, described wire clamp comprises the wire clip body and wire clamp cover plate that connect with firmware, and both tops surround line chamber, crimp Support Level bottom wire clip body.

Further, described wire clamp comprises the wire clip body and wire clamp cover plate that connect with firmware, and described wire clip body is hook type, is provided with the connecting hole corresponding with wire clip body, crimps Support Level bottom wire clip body in the middle part of wire clamp cover plate.

Further, described firmware is bolt.

Further, lateral part and the described line parallel that protects of the described font of falling T are arranged, and described Support Level is steel strand wire, and described tup two ends are hemisphere.

Further, when described stockbridge damper number is 3, protect on line described in being evenly arranged in.

The beneficial effects of the utility model are:

The steel cord end of the outside coated aluminium lamination of every root all will be processed into hemispherical, to avoid corona, also can avoid scratching optical cable.Steel wire external sheath aluminium lamination, has higher, the stronger decay resistance of intensity and more excellent electrician's performance.The steel wire close-packed arrays of the many coated aluminium laminations in outside covers whole cable outer layer, the spiral strand of the steel wire of outside coated aluminium lamination is to twisting to contrary with cable outer layer, cable forms grip force, avoid wire slippage, decrease the wearing and tearing of wire, better dispersion concentrated stress, strengthens the vibrationproof performance of protecting lines, surfacing.Stockbridge damper compact conformation is flexible, uses simple installation, is convenient at transmission line installation exercise.Multiple stockbridge damper is arranged on whole piece and protects on line, installs simple and convenient, reduces difficulty of construction, protects than segmentation the generation that lines are more conducive to preventing line corona, increases the vibrationproof performance of stockbridge damper.
