Description
Technical field
The utility model relates to the compound stockbridge damper of a kind of stockbridge damper, particularly a kind of powerful damping capacity.
Background technology
Overhead transmission line aeolian vibration is a kind of phenomenon of the wire mechanical oscillation that cause of the excitation due to wind, is a kind of small amplitude motion.The wind speed that causes wire aeolian vibration is also little, normally in the scope of 0.5-10m/s.Vibrate the lasting time longer, be generally a few hours, sometimes can reach a couple of days.The double-amplitude of vibration is generally not more than 2-3 times of diameter of wire, and the frequency of vibration is about 3-120Hz, and due to the damping action of wire, the vibration frequency range that wire is threatened is generally 3-80Hz, the key protection frequency band of vibrationproof work that Here it is.Stockbridge damper is a kind of main anti-vibration element of overhead transmission line, and the quality of its performance directly affects the security of operation of circuit.Spring, damping, quality and the moment of inertia system that must form from steel strand wire and the tup of stockbridge damper, set up stockbridge damper Mathematical Modeling, and based on this, analyze the stockbridge damper natural frequency of vibration, power characteristic, and power is the mechanical property such as characteristic and phase characteristic frequently.These performances and anti-vibration hammer quality, moment of inertia, steel strand wire rigidity and length etc. are closely related.The vibration suppression principle of stockbridge damper is by after the vibration mechanical energy absorption of wire, it, the form with heat energy and acoustic energy discharges.
Along with the construction of China's extra-high voltage grid, increasing line design person has recognized is badly in need of the vibration protection of power transmission line to carry out more deep research, and at power transmission line wind-induced vibration this respect, much remains to be done.Traditional stockbridge damper is generally to consist of two cast iron tups, steel strand wire and clamp, and antivibration, damping capacity are poor, and the amplitude sometimes producing because of wind is excessive, and this design can not meet people's needs.
Utility model content
The purpose of this utility model is, a kind of compound stockbridge damper is provided.The utility model can strengthen antivibration, damping capacity.
The technical solution of the utility model: a kind of compound stockbridge damper, it is characterized in that: comprise supporting plate and steel strand wire, supporting plate both sides are respectively equipped with spring, two springs are arranged on steel strand wire through spring connector, described steel strand wire two ends are provided with tup, steel strand wire middle part is upwards provided with for being suspended to the hook on electric wire, and steel strand wire middle part is to having permanent magnet, and described supporting plate middle part is provided with the coil coordinating with permanent magnet.
In aforesaid compound stockbridge damper, be also provided with coil cover on described supporting plate, coil puts installation coil.
In aforesaid compound stockbridge damper, described steel strand wire are the steel strand wire with radius of curvature.
Compared with prior art; the effect that absorbs vibrational energy is played in the combination of the utility model steel strand wire and tup combination and permanent magnet, coil and spring jointly; form compound vibrationproof; antivibration, damping capacity have been strengthened; also on strand structure, adopted warp architecture (thering is radius of curvature), can absorb the vibration wave within the scope of multi-frequency more, and increase electric and magnetic oscillation damping device; strengthen effectiveness in vibration suppression, can effectively protect power transmission line to be destroyed.

On described supporting plate 5, be also provided with coil cover 8, on coil cover 8, coil 7 be installed.
Described steel strand wire 2 are the steel strand wire (being equivalent to warp architecture) with radius of curvature, and radius of curvature can regulate in design process according to vibration damping demand.
Described steel strand wire 2 and tup 1 can play the effect that absorbs vibrational energy when overhead electric power transmission line vibrates.
Described permanent magnet 9 and coil 7 can play the effect that absorbs vibrational energy when spring 4 vibration.
Operation principle of the present utility model is as follows: on steel strand wire, by spring linker, hang with two springs, spring lower end hangs with supporting plate.On described supporting plate, be provided with coil cover, in coil cover, prevented coil; Described permanent magnet is arranged on steel strand wire, and steel strand wire can be suspended on electric wire by hook; Described steel strand wire and tup can play the effect that absorbs vibrational energy when overhead electric power transmission line vibrates; Described permanent magnet and coil can play the effect that absorbs vibrational energy when spring vibration.
