Description
Technical field
This utility model relates to a kind of electric armour clamp, particularly a kind of preformed cracking separation rod being applied on high-tension line。
Background technology
Overhead power transmission conducting wire wave be wind excitation use most under, one produced by ice coating wire significantly, low-frequency oneself vibrations, conductor galloping the large-area power-cuts and the line impairments accident that cause happen occasionally。Cracking separation rod is a kind of Anti-galloping device for overhead transmission line, at home large-scale application on circuit。Cracking separation rod is divided into again swinging conductor spacer, fixed conductor spacer and pre-twisting type conductor spacer, and wherein pre-twisting type conductor spacer adopts and arranges preformed armor rods on wire clamp, is wound in the helical form of hollow by two strands of preformed armor rodses, by wrapped in wire in hollow space with fixing。Being characterized in that of pre-twisting type conductor spacer, the good fixing effect to wire, difficult drop-off, shortcoming is in that the structure of wire clamp and conductor spacer body is comparatively fixing, and Anti-galloping effect is not so good as swinging conductor spacer。
Utility model content
The purpose of this utility model is in that: provides a kind of Novel pre-hinged cracking separation rod, further increases Anti-galloping performance, realized by following technical proposals in existing preformed design basis:
A kind of pre-twisting type conductor spacer, including two or more wire clamp joints, and it is arranged on the top-twisted wire-clip on wire clamp joint, is connected by connecting tube between each wire clamp joint, being provided with wire grooves on top-twisted wire-clip, preformed armor rods chuck is arranged at wire grooves two ends。
As selection, described wire clamp joint is hollow structure, and side is provided with wire clamp entrance, wire clamp joint is internally provided with centre bearing, top-twisted wire-clip is inserted in wire clamp joint by wire clamp entrance, on the centrally disposed bearing of afterbody, makes top-twisted wire-clip can rotate around centre bearing。
As selection, described wire clamp joint includes two laterally zygomorphic molectrons, is provided with cushion pad in described molectron, it is arranged in molectron by draw-in groove, upper and lower molectron is bolted, and after top-twisted wire-clip inserts wire clamp joint, tail end contacts with cushion pad over and under。
As selection, described cushion pad is cross rubber buffer。
As selection, described cross rubber buffer medium position is hollow-core construction, and centre bearing is provided with one layer of cylindrical rubber cushion pad, in the hollow position, middle part that described cylindrical rubber cushion pad is arranged at cross rubber buffer。
As selection, described connecting tube is hollow pipe, and connecting tube adopts crimping form to be connected with wire clamp joint。
As selection, in wire grooves, conductive contact position is provided with rubber buffer sheet。
As selection, the opening angle of described wire clamp entrance is 45 °-135 °。
Of the present utility model it is characterized in that:
1. by being arranged on the centre bearing of wire clamp joint by top-twisted wire-clip, making wire clamp sandwich online in the opening angle of mouth and rotate, what make wire waves Angle ambiguity within the specific limits, improves the Anti-galloping performance that conductor spacer is overall。
2., by arranging cylindrical rubber cushion pad and cross rubber buffer, make wire clamp afterbody obtain the buffering from cushion pad when rotating, improve rotational stability。
3. in wire grooves, conductive contact position is provided with rubber buffer sheet, also can play buffering effect when wire rotates in preformed armor rods cavity。
In sum, the beneficial effects of the utility model are: overall structure is stable, improve the Anti-galloping performance of conductor spacer for preformed armor rod。
