Abstract
The utility model relates to a stockbridge damper, it mainly comprises the couple of establishing in big, little hammer block and the cross arm at flexible cross arm both ends, and wherein, the couple is greater than the distance with big hammer block with the distance of little hammer block. The utility model has the advantages that: the hammer bodies with different sizes and masses are adopted, so that the response frequency range of the traditional shockproof hammer is expanded, and the corona is reduced because the shapes of the large hammer body, the small hammer body and the hook have no edges and corners. In addition, the hook is made of aluminum alloy, and the energy loss of the lead can be reduced.
Description
Technical field
The utility model relates to a kind of stockbridge damper, the stockbridge damper of especially a kind of rotating hanging on transmission line.
Background technology
The phenomenon of overhead transmission line ubiquity gentle breeze vibrations, long-term vibrations can cause the fixed terminal place lead wear and rupture of circuit and shaft tower, for preventing the generation of this type of accident, at present generally be on the overhead transmission line of certain span, especially in the open air on the circuit that sets up with the area, air port, be linked with stockbridge damper, traditional stockbridge damper, because the hammer body uniform quality at flexible cross-arm two ends, and hook places the central authorities of flexible cross-arm, response frequency scope when its hammer body is shockproof is narrow, generally can only cover in the 10-70HZ scope, far can not adapt to the frequency range of natural environment to the transmission line influence.
Summary of the invention
The purpose of this utility model is: the practical problem at traditional stockbridge damper exists provides a kind of novel stockbridge damper.
The purpose of this utility model is achieved in that a kind of stockbridge damper, form by the hook on two hammer bodies, flexible cross-arm and the cross-arm, it is characterized in that: at flexible cross-arm two ends the large and small hammer body that quality does not wait is set respectively, and the distance of hook on the cross-arm and little hammer body greater than with the distance of big hammer body.
Advantage of the present utility model is: because at large and small two hammer bodies that do not wait of flexible cross-arm two ends employing, wherein, response frequency when big hammer body is shockproof is the end of than, and the response frequency of little hammer body is higher, combine, can expand the frequency range of stockbridge damper when shockproof greatly, per sample test, when shockproof, its response frequency can be from 6HZ to the 150HZ scope.Because the profile of large and small hammer body and hook is the smooth surface that does not have corner angle, has reduced the generation of corona.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cut-away view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is further described:
As seen from Figure 1, the utility model is made up of big hammer body 2 and hand hammer body 3 that flexible cross-arm 1 two ends are provided with respectively, the profile of big hammer body 2 and hand hammer body 3 should be the smooth surface of no corner angle, flexible cross-arm 1 is provided with the hook of being made up of coupler body 4, shelves tongue 5, a coupler body 4 and a shelves tongue cooperatively interact by nut 6, the distance of hook and hand hammer body 3 greater than with the distance of big hammer body 2.In the present embodiment, what described flexible cross-arm 1 adopted is steel strand wire, and in addition, flexible cross-arm 1 also can adopt elastic steel sheet or spring.
As seen from Figure 2, hook is made up of coupler body 4 and shelves tongue 5, and coupler body 4 and shelves tongue 5 cooperatively interact by nut 6, and the root of coupler body 4 and flexible cross-arm 1 are solidified as a whole, and the profile of hook should be the smooth surface that does not have corner angle.Hook can adopt the aluminium alloy manufacturing in the present embodiment.
Claims (5)
1, a kind of stockbridge damper, form by the hook that is provided with on two hammer bodies, flexible cross-arm and the cross-arm, it is characterized in that: at soft cross-arm two ends the large and small hammer body that quality does not wait is set respectively, and the distance of hook on the cross-arm and little hammer body greater than with the distance of big hammer body.
2, stockbridge damper according to claim 1 is characterized in that: described flexible cross-arm can be steel strand wire or elastic steel sheet or spring.
3, stockbridge damper according to claim 1 is characterized in that: the profile of described large and small hammer body all should be the smooth surface that does not have corner angle.
4, stockbridge damper according to claim 1 is characterized in that: described hook is made up of coupler body and shelves tongue, and coupler body cooperates by nut with the shelves tongue, and the root of coupler body and flexible cross-arm are solidified as a whole.
5, according to claim 1 or 4 described stockbridge dampers, it is characterized in that; Described hook can adopt the aluminium alloy manufacturing, and its profile should be the smooth surface that does not have corner angle.
