Abstract

A multi-frequency vibration damper comprises a wire clamp and a matching pressure block connected with the wire clamp via a bolt component, a steel stranded wire is transversely and fixedly connected with the lower portion of the wire clamp, two ends of the steel stranded wire are both connected with hammer heads, lengths of the steel stranded wires on two sides of the wire clamp are different, spatial positions of the two hammer heads at two ends of the steel stranded wire are staggered angularly to form an asymmetric multi-frequency vibration damping distributed structure. Distances from the hammer heads on two sides to the wire clamp are unequal, spatial positions of the hammer heads are staggered angularly, vibration damping frequency range of the vibration damper can be enlarged greatly by the aid of the asymmetric structural form, rotary vibration is eliminated better, number of vibration dampers needing to be mounted on lines can be reduced evidently, design and mounting costs of the lines are saved, the utilization effect is reliable, and operational stability and safety of the lines are increased.

Description

The multifrequency stockbridge damper
Technical field: the utility model relates to the aerial cable protection gold utensil that uses on a kind of overhead power line.
Background technology: on overhead power line, all need install and use stockbridge damper usually, get loose with the cable vibration of avoiding wind etc. to cause.Existing stockbridge damper generally is that two tups are symmetricly set on the wire clamp both sides by steel strand wire, find that the vibrationproof number of frequencies of this form is less in actual the use, because conditions such as weather change, the scope of the vibration frequency that produces is bigger, for the effectively vibration of control aerial condutor, must increase the installation quantity of stockbridge damper, increase the cost of line design, installation so greatly.And the design of tup is also reasonable inadequately, is subjected to the influence of rain, snow, ice etc. easily, easily produces corona simultaneously, these problems occur and brings bigger hidden danger to stability and the fail safe that circuit moves.
Summary of the invention: at the deficiencies in the prior art, the utility model provides a kind of anti-vibration frequency wide, service-strong multifrequency stockbridge damper.
The utility model comprises wire clamp and the supporting briquetting that is connected by bolt assembly, the bottom of wire clamp is fixedly connected with horizontal steel strand wire, the two ends of steel strand wire all are connected with tup, be distributed in the steel strand wire length difference on wire clamp both sides, and the locus angle of two tups at steel strand wire two ends staggers, and constitutes asymmetric multifrequency vibrationproof distributed architecture.
Unequal and locus angle tup of the distance of both sides of the present utility model tup and wire clamp staggers, this dissymmetrical structure form can increase the vibrationproof frequency range of stockbridge damper greatly, eliminate the rotary type vibration preferably, can obviously reduce and need the stockbridge damper quantity of installing on the circuit, save the cost of line design, installation, result of use is reliable, improves the stability and the fail safe of circuit operation.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: Fig. 1 is the main structure schematic diagram of embodiment.
Fig. 2 is the A-A generalized section of Fig. 1.
Embodiment: as shown in the figure, wire clamp 1 connects supporting briquetting 2 by bolt assembly 4, the bottom of wire clamp 1 is fixedly connected with horizontal steel strand wire 3, the two ends of steel strand wire 3 all are connected with tup 5, be distributed in the steel strand wire 3 length differences on wire clamp 1 both sides, and the locus angle of two tups 5 at steel strand wire 3 two ends staggers, and constitutes asymmetric multifrequency vibrationproof distributed architecture.Tup 5 can adopt smooth rotation body structure, and expand at both ends, constitutes corona free formula tup, and the tup 5 of this form is not subject to the influence of rain, snow, ice etc., does not produce corona simultaneously.Junction between wire clamp 1, steel strand wire 3, the tup 5 all is the riveted syndeton, and the grip of Lian Jieing is stronger like this, is difficult for loosening.
During use, the upper end of wire clamp 1 and briquetting 2 cooperated by bolt assembly 4 clamp the installation site that is suspended on aerial condutor 6 and get final product.The wire clamp 1 of present embodiment is the circular arc plane of rotation with the contact-making surface of briquetting 2 lower ends, constitutes many specifications lead and rotates adaptive structure, and when pressing from both sides the aerial condutor 6 of different thicknesses specification like this, wire clamp 1 and briquetting 2 can relatively rotate self adaptation.
