Abstract
The utility model provides a take damper of arcuation steel strand wires. Including steel strand wires, weight, linkage. Level in the middle of steel strand wires are made, both sides become the wave of symmetry, and the weight is through the recess with to have telescopic steel strand wires fixed. The middle part of steel strand wires is fixed with linkage. The utility model discloses at weight center with the certain condition of linkage width between centers under, increased the length of steel strand wires, this is just also for the selection of the arrangement form between steel strand wires and the tup more than providing more, simultaneously when the tup vibrate, the level of steel strand wires also can be constantly changeable to length, and these factors have increased the scope of antivibration frequency guaranteeing that the place where troops were originally stationed shakes under the unchangeable circumstances of hammer antivibration dominant frequency, and messenger's antivibration scope is wider.
Description
Technical field
This utility model belongs to electric armour clamp technical field, relates to a kind of damper hung on transmission line of electricity.
Background technology
Under wind action, the power transmission line moment is in vibrational state, and according to frequency and the difference of amplitude, the vibration of power transmission line substantially can be divided into three kinds: high frequency aeolian vibration a little, and in intermediate frequency, wake galloping and the low frequency of width are significantly waved.These three vibration all can cause damage to transmission line of electricity, wherein with aeolian vibration occur the most frequent.
When wind laterally blows over power transmission line, can form, at it, the toll bar whirlpool stably come off behind, make power transmission line generation altofrequency, the aeolian vibration of short arc.This vibration can cause, ground wire occurs the disconnected stock of fatigue, and serious meeting causes line-outage contingency, threatens the service life of overhead transmission line；Meanwhile, this vibration also limit transmission line of electricity and uses the raising of stress, limits the reduction of transmission line of electricity cost.
In order to suppress the impact of aeolian vibration, improving the operation safety of power transmission line, conventional method is to install damper at power transmission line two ends, and damper is divided into many types according to the difference covering frequency range.The damper that uses in the market is many to be made up of suspension arrangement, steel strand wires, weight three part, wherein main is vibrated by tup and between steel strand wires stock, friction is consumed energy.This utility model, by improveing steel strand wires, proposes one and covers the wider array of damper of frequency range.
Summary of the invention
The purpose of this utility model is to improve damper existing on market, designs a kind of strong adaptability, life-span length, simple in construction, damper easy to use.
The technical solution of the utility model is: a kind of damper, it is characterised in that include steel strand wires, weight and suspension arrangement, wherein:
In the middle part of described steel strand wires straight, both sides become symmetrical waveform；Described weight is fixed on described steel strand wires two ends；Suspension arrangement it is provided with in the middle part of damper；
Described suspension arrangement includes two block casting iron plates, one of longer, one piece shorter；Two cast iron sheet top and the bottom are adjacent to fix, middle part relatively all convexes, form hollow hole, pass for power transmission line；One end of a longer block casting iron plate in the middle part of described steel strand wires after backrush, for and steel strand wires fix.
Further, two connection cast iron sheets of described damper are fastened by screw, nut, for being secured across the power transmission line of hollow hole.
Further, described damper the inner face of weight have cylinder groove.
Further, the steel strand wires two ends of described damper added with sleeve and are fixedly clamped, and described sleeve outer diameter matches with the cylinder groove internal diameter of described weight, fixes with binding agent between the two.
Further, the side opening of the weight of described damper is provided with two and above screw, is used for installing fastening screw, weight and the sleeved steel strand wires of band is fixed.
Above-mentioned steel strand manufacturing becomes by-level, and both sides become symmetrical waveform, the form of both ends horizontal；Above-mentioned sleeve is respectively fitted over the two ends of steel strand wires, and banding, as the coupling part with weight；Above-mentioned weight is connected with steel strand wires by cylinder groove, and fixes with binding agent, and punch respectively in weight both sides, and sleeve is held out against by DRIVE SCREWS, it is ensured that weight and steel strand wires connect consolidation.
By the steel strand wires of damper cathetus type are improved, use the steel strand wires of undaform, in the case of weight center and suspension arrangement centre distance are certain, adding the length of steel strand wires, this most just provides more choices for the arrangement between steel strand wires and tup；Corrugated steel strand wires can make its rigidity change, and simultaneously when tup vibrates, the level of steel strand wires also can be continually changing to length, and these factors, in the case of ensureing that place where troops were originally stationed vibration hammer vibrationproof dominant frequency is constant, add the scope of anti-vibration frequency, make vibrationproof wider.
This utility model damper simple in construction, easy for installation, by former linear steel strand wires are modified to waveform, add the scope of anti-vibration frequency, the suitability is higher.
