Description
Technical field
The utility model relates to electrical equipment technical field, is specially a kind of Multifunctional power transmission line stockbridge damper.
Background technology
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 is an iron leg rod.Because it carrys additionally at circuit tower bar suspension point place, to absorb or damping vibration energy, change circuit wobble frequency, prevent the vibration of circuit or wave.But traditional stockbridge damper is because hammer body is from time waving with electric wire, and self resistance is little, when being shaken pendulum by wire belt, best shockproof effect can not be reached; Further, different environmental conditions, its wind-force size is not identical yet, once the stressed excessive or stressed too small shockproof effect that can not be all stockbridge damper and reach best of stockbridge damper.
Utility model content
The purpose of this utility model is to provide a kind of Multifunctional power transmission line stockbridge damper, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of Multifunctional power transmission line stockbridge damper, comprise wire clamp, the inner chamber of described wire clamp runs through steel strand wire, the two ends of described steel strand wire are all fixed with hammer body, the both sides sidewall of described hammer body is all fixed with choke plate, described choke plate is evenly provided with choke concave point, described choke plate comprises the first expansion joint, the sidewall of described first expansion joint is fixed with the first spacing preiection, described first expansion joint is socketed with the second expansion joint, the sidewall of described second expansion joint is fixed with the second spacing preiection, and the below of the second spacing preiection evenly has first spacing hole suitable with the first spacing preiection, described second expansion joint is socketed with the 3rd expansion joint, the sidewall of described 3rd expansion joint evenly has second spacing hole suitable with the second spacing preiection.
Preferably, described first spacing preiection and the second spacing preiection are all fixed together with the sidewall of the first expansion joint and the second expansion joint respectively by elastic plectrum, and the first expansion joint is plugged in the chute of the inner chamber being opened in the second expansion joint.
Preferably, described choke plate is fixed together by the sidewall of the mode of welding or be spirally connected and hammer body, and the height of choke plate is greater than the diameter of hammer body.
Preferably, described choke concave point is hemisphere, and the diameter of choke concave point is 0.5 to 1.5 millimeter.
Compared with prior art, the beneficial effects of the utility model are: this Multifunctional power transmission line vibration hammer structure is simple, fixes choke plate by the sidewall at hammer body, and the area making it contact wind increases, and improves its damping effect greatly, and increases the stability of hammer body; Further, adopt telescopic choke plate, can regulate in the size of different environment to choke plate, thus make its result of use better, reach best damping effect.
Accompanying drawing explanation
