Description
Technical field
The utility model relates to a kind of stockbridge damper, is specifically related to a kind of stockbridge damper that hangs on the transmission line.
Background technology
Known to a person skilled in the art, the effect of meteorological conditions such as overhead power line wind-engaging, ice, low temperature makes circuit produce vibration and waves, during vibration, frequency is higher and amplitude is very little, so make overhead wire at the suspension point place repeatedly by stubborn folding, cause fatigue of materials, cause disconnected strand, broken string accident at last; When waving, frequency is very low, and amplitude is very big, is easy to cause alternate flashover, causes serious accidents such as line tripping, power failure or burn lead.Therefore, stockbridge damper just arises at the historic moment for the electric armour clamp of eliminating the circuit self-vibration and eliminating the resonance that wind etc. causes as a kind of.
The wire clamp that stockbridge damper on the existing market generally comprises the hammer body that is connected the steel strand wire two ends and is articulated in the steel strand wire centre position, by wire clamp with the stockbridge damper hanging support on lead, yet in actual the use, because stockbridge damper is applied to the more abominable field of natural environment or air port, therefore, in rugged environment too, stockbridge damper plays prevents that conductor vibration or the effect of waving are very little.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, provides a kind of simple in structure, novel in design and can more effective reduction conductor vibration frequency or wave the stockbridge damper of amplitude.
For achieving the above object, the utility model adopts a kind of rotating stockbridge damper, comprise steel strand wire, hammer body, connector and wire clamp and clamp, described hammer body is fixedly mounted on the two ends of described steel strand wire, described connector has the installation portion of horizontally set and the vertical upwardly extending cylindrical connecting rod from the centre position of this installation portion, the top of described cylindrical connecting rod is provided with cylinder table, the diameter of this cylinder table is greater than the diameter of described cylindrical connecting rod, described wire clamp comprises be used to being fixed on the clamping section on the lead and vertically extending the sleeve that arranges downwards from this clamping section, the diameter of described clamp and the internal diameter of described sleeve adapt, offer the through hole of the diameter adaptation of diameter and described cylinder table on the diapire of described sleeve, offer on the external cylindrical surface of this sleeve for clamp being interted the into opening of described barrel bore, offer on the described clamp be used to the fluting that is fitted to cylindrical connecting rod, the through hole that the cylinder table of described connector passes on the described collet base wall enters barrel bore, and by described clamp by open side to interting into barrel bore, and then make the fluting of clamp be fitted to described cylindrical connecting rod and form connector and wire clamp between longitudinal spacing.
By the above-mentioned improvement to prior art, owing between wire clamp and steel strand wire, connector is set, the cylinder table of this connector enters inner chamber by the through hole on the collet base wall, then with the open side of clamp from the sleeve external cylindrical surface to interting into barrel bore and make the fluting of clamp and cylindrical connecting rod adaptive, then make clamp freely fall on the collet base wall, apparent clamp is arranged between diapire and the cylinder table, and then the feasible connector that is fixed together, form longitudinal spacing between steel strand wire and hammer body and the wire clamp, and reached the effect that the hammer body of stockbridge damper and steel strand wire and connector can rotate with the wind, therefore, for lead, stockbridge damper of the present utility model is conducive to weaken or absorb vibration frequency more, change the circuit wobble frequency, reduce the vibration of circuit or the amplitude of waving.
