Abstract
The invention discloses the damper for transmission line of electricity, the ring set of the spring with different length is socketed on hammer body the setting of this damper, such it is designed to so that damper has multiple resonant frequencies in vibration processes, disclosure satisfy that the demand of the aeolian vibration energy dissipation of different resonant frequencies, thus dissipation energy is strong.
Description
Technical field
The present invention relates to the mild wind vibrationproof field of transmission line of electricity, in particular it relates to the damper for transmission line of electricity.
Background technology
The aerial conducting wire that highland sets up easily causes mechanical vibration phenomenon due to the impact of aerial air-flow, and mechanical vibration are with micro-
Wind causes the oscillation phenomenon of generation the most frequent, and this vibration frequently results in the short stock of fatigue of wire, and then has influence on entirely defeated
The safe operation of electric line and Financial cost.
The actual wind speed causing conductor vibration less, but vibration duration is longer, generally a few hours, has
Shi Keda a couple of days, thus prevent or reduce this vibration actual transmission of electricity demand is particularly important.Prevent or reduce
This vibration is it is necessary to first understand the characteristic causing required for this vibration.General wind speed is steady, and wind direction is more perpendicular to
Overhead transmission line, aeolian vibration is more susceptible to, and in addition landform open area also easily produces aeolian vibration.For reducing wire
Aeolian vibration phenomenon, often installs damper on wire.
Although existing damper is simple, vibration-isolating effect is not good, is in particular in, the hammer body of damper swings up and down
The energy expenditure brought causes the wire that wind brings to swing energy loss less it is impossible to effectively disperse the mechanical vibration of wire.
For this problem, the present invention have devised a kind of damper of the strong energy consuming aeolian vibration of energy.
Content of the invention
The technical problem to be solved is the damper providing for transmission line of electricity, the hammer body of this damper setting
On be provided with ring set, ring set is additionally provided with the spring of carbon fibre materials so that whole damper being capable of anticorrosion, lightning protection
Hit, and the setting of multiple spring can be when aeolian vibration, because multiple spring vibrations are provided that multiple different frequencies
Vibration, expand the frequency response width of whole damper such that it is able to the different frequency energy of aeolian vibration can be consumed, play
The purpose of vibrationproof.
The present invention solves the above problems and be employed technical scheme comprise that：
For the damper of transmission line of electricity, including wire clamp, steel strand wires, hammer body, wire clamp include wire clip body, wire clamp cover plate,
Wire clamp lower end and wire clamp spiral shell spring washer, the inner face of wire clip body upper end is arc, and the inner face of wire clamp cover plate upper end is arc
Groove, the upper end occlusion of the upper end of wire clip body and wire clamp cover plate forms to bore a hole under an annular and passes through for cable, wire clamp spiral shell bullet
Pad is through wire clip body lower end and wire clamp cover plate lower end so that the degree of engagement of adjustment wire clip body and wire clamp cover plate is locked
Cable, wire clamp lower end and wire clamp cover plate connect, and wire clamp lower end is provided with the lower perforation passing through for steel strand wires；
Steel strand wires are located at the lower section of wire clamp and pass through lower perforation to be fixedly connected with wire clamp, and hammer body is identical 2 and difference
It is arranged on the two ends of steel strand wires, described hammer body is narrow hollow ceramic between the alleviating distention in middle-JIAO of two ends, hammer body is that the big centre in two is little, hammer body
One end away from wire clamp is circular arc, the hammer body described in 2 is provided with the ring set being socketed on hammer body, ring set is provided with
Spring containing carbon fibre materials, spring outwards also connect with arc-shaped carbon fiber wall, described arc-shaped carbon fiber wall and spring
Quantity corresponds.
The advantage of present invention setting is：Hammer body makes damper more corrosion-resistant using hollow ceramic material, using the longevity
Life is longer, and the ring set that in addition between the alleviating distention in middle-JIAO of hammer body shape two ends, narrow setting is prevented from being arranged on hammer body slips, and ring set sets
The spring of the carbon fibre materials put can vibrate when aeolian vibration, thus providing shaking of multiple difference frequency response to stockbridge damper
Dynamic, and the setting of carbon fibre materials can corrosion-resistant and high-temperature resistant, also will not draw thunderbolt, arc-shaped carbon fiber wall and spring connect
It is capable of the vibration of spring difference frequency response, if light has spring, do not enable the transmission vibrated.
Preferably, spring is 2 and more than 2.The spring being connected on ring set can be multiple, so can ensure that
More cross the vibration of frequency response, thus expanding frequency response width, for there is no the aeolian vibration of certain frequency vibration regularity, Neng Goukuan
What the enough big Hz-KHzs of degree were better able to adapt to it produces the energy such that it is able to more suitable dissipation aeolian vibration.
Preferably, the length between spring is unequal.The coefficient of elasticity of the unequal such spring of the length between spring
Different, elastic force is different, and frequency of vibration is also different so that the frequency response between multiple springs is different, also expands further
Frequency response width, is better able to adapt to the changeable aeolian vibration of frequency, thus play the purpose of Fang Zhen.
Preferably, the number of springs on the ring set of setting on hammer body described in 2.
Preferably, the non-central location that described wire clamp is arranged on steel strand wires is eccentric setting.Bullet on the ring set of both sides
The eccentric setting of wire clamp in the case of spring quantity is different, can be selected, so can either ensure that damper is flat on cable
Weighing apparatus, can provide more frequencies to vibrate again, realize the fast dissipation of aeolian vibration energy so that cable can quickly stop shaking
Dynamic.
The end of steel strand wires is spiral-shaped.
Steel strand wires passage in the tup of hammer body includes the straight line that the end termination of mushroom cavity is connected with end termination
Part, and the inwall of the straight line portion of steel strand wires passage is that spiral-shaped and steel strand wires termination matches.
Also pour cement in the end termination of steel strand wires passage steel strand wires are fixed in hammer body.
Described ring set can move on hammer body.According to actual needs ring set can be moved to obtain broader shaking on hammer body
Dynamic frequency response.
To sum up, the invention has the beneficial effects as follows：
1st, the hammer body of the present invention makes damper more corrosion-resistant using hollow ceramic material, and service life is longer, in addition
The ring set that between the alleviating distention in middle-JIAO of hammer body shape two ends, narrow setting is prevented from being arranged on hammer body slips, the carbon fiber material of setting on ring set
The spring of matter can vibrate when aeolian vibration, thus providing the vibration of multiple difference frequency response to stockbridge damper, and carbon is fine
The setting of dimension material can corrosion-resistant and high-temperature resistant, also will not draw thunderbolt, arc-shaped carbon fiber wall and spring connect and be capable of bullet
The vibration of spring difference frequency response, if light has spring, does not enable the transmission vibrated；
2nd, the spring that the present invention is connected on ring set can be for multiple it is ensured that more cross the vibration of frequency response, thus expanding frequency response
Width, adapts to the aeolian vibration of different frequency, thus fast dissipation aeolian vibration energy；
3rd, present configuration is simple, cheap, can be used in large-scale production and application.
