Description
Technical field
The utility model relates to a kind of electromagnetism Shunt Damping System device, particularly a kind of idle electromagnetism stockbridge damper.
Background technology
In overhead transmission line, wire and lightning conducter usually occur to vibrate consumingly, so that cause the wire accidents such as thigh, gold utensil damage, short-circuit between conductors of breaking, and the safety of power transmission line in serious threat.According to the form of the cause that causes conductor vibration and conductor vibration, can be divided into following several types to the conductor vibration phenomenon: aeolian vibration, subspan oscillation, wave, ice-shedding, laterally percussion, corona are waved, short circuit vibration etc.Wherein, the wire aeolian vibration occurs the most frequently, and it usually causes the disconnected thigh of fatigue of wire.Therefore, the research of wire aeolian vibration is subject to people's attention especially.The vibration protection of existing inhibition conductor vibration mainly adopts stockbridge damper, damping wire, protects the devices such as lines.Wherein stockbridge damper is the main method of pilot aeolian vibration.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, yet existing stockbridge damper complex structure, be awkward, and affects utilization rate.
The utility model content
The purpose of this utility model is, a kind of electromagnetism stockbridge damper is provided.The utlity model has simple in structure and characteristics convenient operation.
The technical solution of the utility model: a kind of electromagnetism stockbridge damper, it is characterized in that: comprise lower bottom base, lower bottom base is provided with pair of permanent magnets, and permanent magnet is provided with magnet sleeve, is set with loop sleeve on magnet sleeve, be provided with coil in loop sleeve, coil is connected with circuit board through wire, and the loop sleeve top is provided with upper bed-plate, and upper bed-plate top is provided with preformed armor rods, the upper bed-plate bottom is provided with damping spring, and damping spring is connected with lower bottom base.
In aforesaid electromagnetism stockbridge damper, described upper bed-plate is provided with preformed armor rods through support.
In aforesaid electromagnetism stockbridge damper, described support and upper bed-plate are welded to connect.
In aforesaid electromagnetism stockbridge damper, described two loop sleeve are arranged on the two ends of upper bed-plate.
Compared with prior art, the utility model can regulate arbitrarily by internal circuit board the frequency range that will control; When the overhead electric power transmission string pendulum is moving, drive damping spring and vibrate together, now between coil and permanent magnet, form a magnetic field, produce induced electromotive force in the change coil due to magnetic flux, corresponding generation induced current.The electric current that shunt circuit on circuit board produces for storing induced field, and the form with heat energy distributes by resistance, thus reduce the induced current between coil and permanent magnet, reduce the vibration frequency of cantilever beam, reach the purpose of controlling vibration.The utility model is simple in structure, and convenient operation has noncontact, machinery-free friction and wear, need not lubricate, the life-span is long and rigidity and the advantage such as damping is controlled, has good economy and reliability.

Embodiment.A kind of electromagnetism stockbridge damper, form as shown in Figure 1, comprise lower bottom base 4, lower bottom base 4 is provided with pair of permanent magnets 7, permanent magnet 7 is provided with magnet sleeve 6, be set with loop sleeve 8 on magnet sleeve 6, be provided with coil 9 in loop sleeve 8, coil 9 is connected with circuit board 10 through wire 11, loop sleeve 8 tops are provided with upper bed-plate 3, upper bed-plate 3 tops are provided with preformed armor rods 1, and upper bed-plate 3 bottoms are provided with damping spring 5, and damping spring 5 is connected with lower bottom base 4.
Described upper bed-plate 3 arranges preformed armor rods 1 through support 2.
Described support 2 is welded to connect with upper bed-plate 3.
Described two loop sleeve 8 are arranged on the two ends of upper bed-plate 3.
Described magnet sleeve 6 also is arranged on the two ends of lower bottom base 4.
Described circuit board 10 can comprise shunt circuit and resistance.
Operation principle of the present utility model is as follows: when the overhead electric power transmission string pendulum is moving, driving damping spring vibrates together, now between coil and permanent magnet, form a magnetic field, produce induced electromotive force in the change coil due to magnetic flux, corresponding generation induced current.The electric current that shunt circuit on circuit board produces for storing induced field, and the form with heat energy distributes by resistance, thus reduce the induced current between coil and permanent magnet, reduce the vibration frequency of cantilever beam, reach the purpose of controlling vibration.
