Abstract
The utility model relates to an anti-slip vibration damper for a plus or minus 600KV DC power transmission line conductor, comprising an anti-slip vibration damper for ultra-high voltage and extra high voltage power transmission line conductors. A steel strand of the vibration damper is sheathed in a circular hole of a wire clip body and is pressed tightly through a special mold; a steel sleeve is respectively sheathed in the steel strand and is fixed against the hexagon outer wall of a hammer head of the vibration damper; and a pre-twisted wire is wound on the outer surface of a conductor in a wire groove of the wire clip body. The anti-slip vibration damper for the plus or minus 600KV DC power transmission line conductor has the advantages that: 1. the anti-slip vibration damper is suitable for large-section conductors of 1000 mm2 with the outer diameter phi of 42.08mm; and 2. the pre-twisted wire and the wire clip body are fixed through the curved groove arranged in the wire clip body, so that the pre-twisted wire is more stably and firmly fixed at the wire clip body without movement and no influence on the holding force on the conductor, and the construction mounting is convenient, without using a special tool.
Description
Technical field
The utility model relates to a kind of being used for ± 660KV DC transmission line line conductor anti-slip type stockbridge damper, belongs to transmission line wire and uses the manufacturing field.
Background technology
Development along with economic society; the continuous increase of electricity needs; traditional superhigh pressure and leads of ultra-high voltage power transmission lines stockbridge damper are that wire clip body and cover plate pass through bolt and clamping wire; along with long operation and the baptism under complicated bad weather condition; may produce because of bolt looseness makes the lead grip not enough; cause and the lead slippage, thereby lose anti-vibration protected effect lead.Secondly, ± 660KV DC power transmission line adopts 1000mm
2Large-section lead, wire diameter Φ are 42.08mm, the present domestic shockproof gold utensil that matches that still do not have
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of being used for ± 660KV DC transmission line line conductor anti-slip type stockbridge damper.
Design: in order to realize above-mentioned purpose of design.± 660KV DC transmission line line conductor comprises tup, steel sleeve, steel strand wire, wire clip body, preformed armor rods with the anti-slip type stockbridge damper.Steel strand wire are inserted in the circular hole of wire clip body, compress by particular manufacturing craft.Steel sleeve is enclosed within respectively in the steel strand wire, and riveting becomes orthohexagonal again, packs in the hexagonal hole of stockbridge damper, by particular manufacturing craft sleeve pipe is done the flange riveting, is adjacent to fixing with tup six side's outer walls.Preformed armor rods is wrapped on the interior lead outer surface of wire clip body wire casing.(traditional structure is that preformed armor rods directly is attached on the outer surface of wire clip body to the built-in curved groove of wire clip body, increase along with running time, be easy to generate tired loosening), can effectively closely cooperate with preformed armor rods, and between the preformed armor rods not because of stressed mutually slippage, thereby fix with wire clip body, part is that preformed armor rods contacts with the stranded of lead outside the wire clip body, thereby the stranded area of increase and lead, therefore a whole set of stockbridge damper and lead permanent fixation.
Technical scheme: ± 660KV DC transmission line line conductor anti-slip type stockbridge damper, it comprises superhigh pressure and leads of ultra-high voltage power transmission lines anti-slip type stockbridge damper, steel strand wire in the described stockbridge damper are inserted in the circular hole of wire clip body and by particular manufacturing craft and compress, steel sleeve is enclosed within respectively in the steel strand wire and is adjacent to fixingly with stockbridge damper tup six side's outer walls, and preformed armor rods is wrapped on the lead outer surface in the wire clip body wire casing.
The built-in curved groove of described wire clip body and closely cooperate with preformed armor rods, fixing.Described preformed armor rods contacts with the stranded of lead.Described steel sleeve is enclosed within the steel strand wire respectively and riveting becomes in the hexagonal hole that packs into the stockbridge damper tup after the orthohexagonal and the flange riveting connects.
The utility model is compared with background technology, and the one, be applicable to 1000mm
2Large-section lead, wire diameter Φ are 42.08mm; The 2nd, preformed armor rods and wire clip body fixing by the built-in curved groove of wire clip body makes preformed armor rods firm stable fixing with it more, do not produce mobilely, do not influence the grip force to lead, and construction install convenience, need not the configure dedicated instrument.

Embodiment
Embodiment 1: with reference to accompanying drawing 1.± 660KV DC transmission line line conductor anti-slip type stockbridge damper, it comprises superhigh pressure and leads of ultra-high voltage power transmission lines anti-slip type stockbridge damper, steel strand wire 3 in the described stockbridge damper are inserted in the circular hole of wire clip body 4 and by particular manufacturing craft and compress, steel sleeve 2 is enclosed within respectively in the steel strand wire 3 and is adjacent to fixingly with stockbridge damper tup 1 six side's outer walls, and preformed armor rods 5 is wrapped on lead 6 outer surfaces in wire clip body 4 wire casings.Described wire clip body 4 built-in curved grooves and closely cooperate with preformed armor rods 5, fixing.Described preformed armor rods 5 contacts with the stranded of lead 6.Described steel sleeve 2 is enclosed within the steel strand wire 3 respectively and riveting becomes in the hexagonal hole that packs into stockbridge damper tup 1 after the orthohexagonal and the flange riveting connects.The built-in curved groove and the lead 6 that 4 preformed armor rodses 5 are passed wire clip body 4 are stranded, thereby reach fixing wire clip body 4, lead 6.During operation, the energy delivery that the vibrations that cause because of gentle breeze along with lead 6 produce is to wire clip body 4, wire clip body 4 is passed to two stockbridge damper tups, 1, two stockbridge damper tup 1 along with the slight vibrations of doing same frequency together by fixing steel strand wire 3, thus consumed energy.
What need understand is: though the foregoing description is to the mentality of designing of the present utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of the utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection range of the present utility model.
