Description
Technical field
The present invention relates to transmission line of electricity wind resistance field, particularly relate to a kind of damper.
Background technology
High-tension overhead line bar position is higher, and span is relatively big, when wire is by wind-force effect, can form high frequency, little amplitude
Motion, this is referred to as aeolian vibration.Wind speed is typically 0.5～10m/s, and frequency is typically 3～100Hz, and the amplitude of vibration is general
Diameter less than 1 times of wire.Owing to amplitude is less, it is not easy to be found, therefore being easier to be left in the basket, time of vibration is longer, and one
As be several hours or the most several days.Any kind of vibration all can threaten the properly functioning 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 bigger economic loss.Wire
Under the effect of aeolian vibration, produce long alternate strain, form stress concentration point.Final causing at stress concentration point is led
The fatigue rupture of line, the fatigue forming wire breaks stock, and contact point generally concentrates application point at the stress of transmission line of electricity, generally outstanding
At vertical line folder.Therefore on high-tension overhead line, often hanging a hand hammer on the wire of insulator both sides, this hand hammer is anti-
Vibration hammer, is used 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, utilize the inertia of weight so that it is steel strand wires produce internal friction and consume most of vibrational energy of aerial line, and air is to weight
Damping consumes part energy, consumes and reflection part energy at shockproof hammer thread clip.
But Stockbridge damper is to utilize the inertia of weight to make its steel strand wires produce internal friction to consume aerial line
Major part vibrational energy, vibration-isolating effect is the best, and the weight of Stockbridge damper is simply simply divided into several etc.
Level, can not well adapt to the wind speed of locality, it is impossible to well adapt to the power characteristic of circuit, also reduce
The vibration-isolating effect of Stockbridge damper.
Summary of the invention
The embodiment of the invention discloses a kind of damper, by arranging in the hollow channel of both sides, the anti-vibration hammer edge of a wing
Steel ball, utilize in vibration processes in damper the collision of steel ball carry out additional power consumption, solve existing Stockbridge vibrationproof
Hammer utilizes the inertia of weight to make its steel strand wires produce internal friction and consumes most of vibrational energy of aerial line and the vibrationproof effect that causes
The most imperfect technical problem.

Detailed description of the invention
The embodiment of the invention discloses a kind of damper, by arranging in the hollow channel of both sides, the anti-vibration hammer edge of a wing
Steel ball, utilize in vibration processes in damper the collision of steel ball carry out additional power consumption, solve existing Stockbridge vibrationproof
Hammer utilizes the inertia of weight to make its steel strand wires produce internal friction and consumes most of vibrational energy of aerial line and the vibrationproof effect that causes
The most imperfect technical problem.
Referring to Fig. 1 to Fig. 2, an embodiment of a kind of damper provided in the embodiment of the present invention includes: connection group
Part, it is arranged on described connection assembly upper ram, is arranged on the hollow channel 5 within described tup, is arranged on described hollow channel 5
Interior steel ball 6；
Connect assembly to be 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 hollow channel 5 also leaves certain after placing steel ball 6
Space, mutually rubs between steel ball 6 and hollow channel 5, steel ball and steel ball so that steel ball 6 can slide to cause in hollow channel
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 connection 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, it is also possible to for multiple, and the quality of steel ball 6 can be the same or different, steel ball
The quality and quantity distribution form of 6 is to determine according to the wind speed installed at damper circuit, in damper the quantity of steel ball 6 and
Quality matches with wind speed, thus plays more preferable vibration-isolating effect.
Said hollow passage 5 is cylindrical, it is also possible to for other shapes, is intended merely to allow the steel ball 6 can be at 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.
Hollow channel 5 is provided with damping fluid, adds power consumption by increasing damping.
The detailed description that the above is the structure to a kind of damper and connected mode is carried out, for ease of understanding, below will be with
The application of a kind of damper is illustrated by one concrete application scenarios, and application examples includes:
First pass through experiment test and need to install the wind speed of transmission line of electricity of damper, so that it is determined that and select with wind speed
The tup of the Mass Distribution that matches form sum dimension ball 6, installs tup, steel strand wires 2 and damper chuck 1 and combines, so
By damper chuck 1, damper is fixed on overhead transmission line afterwards, as it is shown on figure 3, transmission line of electricity two ends can be used
One, it would however also be possible to employ half grade of vibrationproof method.When running into aeolian vibration, damper utilizes gravity to consume a part of aeolian vibration
Time wind be defeated by the energy of wire, simultaneously inside damper equipped with steel ball 6 up-down vibration and left and right roll, the space left is permissible
Make between steel ball and steel ball, steel ball 6 mutually collides with hollow channel 5, and steel ball 6 motion has kinetic energy, increases damper
Power consumption, reaches good vibration-isolating effect.
