Background technology
High-tension overhead line bar position is higher, and span is larger, when wire is subject to wind-force to act on, can form high frequency, little amplitude
Motion, this is referred to as aeolian vibration., typically in 0.5～10m/s, typically in 3～100Hz, the amplitude of vibration is general for frequency for wind speed
Less than 1 times of diameter of wire.Therefore it is easier to be ignored it is not easy to be found because amplitude is less, time of vibration is longer, one
As be a few houres or sometimes up to several days.Any kind of vibration all can threaten the normal operation of transmission line of electricity.Transmission line of electricity
Aeolian vibration if not subjected to control, will result in serious injury and death, and cause larger economic loss.Wire
Produce long alternate strain in the presence of aeolian vibration, form stress concentration point.Finally cause to lead in stress concentration point
The fatigue rupture of line, the fatigue forming wire is stranded, and contact point generally in the stress concentration application point of transmission line of electricity, is generally hanging
At vertical line folder.Therefore on high-tension overhead line, often hang a hand hammer on the wire of insulator both sides, this hand hammer is anti-
Vibration hammer, for reducing the vibration that wire is heaved out because of wind-force.
At present, conventional damper is Stockbridge damper, and when aerial line occurs vibration, damper is transported up and down
Dynamic, using weight inertia so as to steel strand wires produce most of vibrational energy that internal friction consumes aerial line, air is to weight
Damping consumes part energy, consumes and reflection part energy at shockproof hammer thread clip.
But Stockbridge damper is to make its steel strand wires produce internal friction using the inertia of weight to consume aerial line
Most of vibrational energy, vibration-isolating effect is not good, and the weight of Stockbridge damper be simply simply divided into several etc.
Level, the wind speed that can not well adapt to locality, it is impossible to well adapt to the power characteristic of circuit, also reduces
The vibration-isolating effect of Stockbridge damper.
Utility model content

Put, other accompanying drawings can also be obtained according to these accompanying drawings.
A kind of structural representation of damper for providing in this utility model embodiment for the Fig. 1；
Fig. 2 is a kind of structural representation of the tup of damper of offer in this utility model embodiment；
Fig. 3 is arranged on the schematic diagram on transmission line of electricity for a kind of damper providing in this utility model embodiment.
Specific embodiment
This utility model embodiment discloses a kind of damper, by the hollow channel of anti-vibration hammer edge of a wing both sides
Setting steel ball, the collision using steel ball in damper in vibration processes carries out additional power consumption, solves existing Stockbridge
Damper makes its steel strand wires produce using the inertia of weight, and internal friction consumes most of vibrational energy of aerial line and leads to prevents
The imperfect technical problem of effect of shaking.
Refer to Fig. 1 to Fig. 2, an a kind of embodiment of the damper providing in this utility model embodiment includes：Even
Connected components, it is arranged on described coupling assembly upper ram, is arranged on hollow channel 5 within described tup, is arranged on described hollow
Steel ball 6 in passage 5；
Coupling assembly is used for connecting overhead transmission line and tup；
The diameter of steel ball 6 is less than the internal diameter of hollow channel 5, and also leaves certain after hollow channel 5 placement steel ball 6
Space, so that steel ball 6 can slide in hollow channel cause mutually to rub between steel ball 6 and hollow channel 5, steel ball and steel ball
Wipe.
Aforementioned tup specifically includes lumped mass block 3 and the edge of a wing 4, and the edge of a wing 4 is arranged on the two ends of lumped mass block 3, hollow
Passage 5 is arranged in the edge of a wing 3.
Aforementioned coupling assembly specifically includes damper chuck 1 and steel strand wires 2, and damper chuck 1 is connected on overhead transmission line,
Steel strand wires 2 are arranged on the lower end of damper chuck 1, and tup is arranged on the two ends of steel strand wires 2.
The quantity of steel ball 6 can be one or multiple, and the quality of steel ball 6 can be the same or different, steel ball
6 quality and quantity distribution form be according to install damper circuit at wind speed determine, in damper the quantity of steel ball 6 and
Quality is matched with wind speed, thus playing more preferable vibration-isolating effect.
Said hollow passage 5 is cylindrical or other shapes, is intended merely to allow the steel ball 6 can be in hollow channel 5
In slidably, collision consume the energy of aeolian vibration, and cylindrical, hollow passage more saves space.
The end on the edge of a wing 4 of tup is circular arc, effectively reduces the skyborne resistance of tup, it also avoid tip and put
Electricity.
