Many years of experience according to meteorological observation and transmission line operation, generally going into winter or season in the early spring, when temperature between-5～0 ℃, wind speed is when 1～15m/s, as atrocious weather situations such as thick fog, rainfall, snowfalls, air humidity surpasses 85%, will produce icing based on glaze, rime in conductive line surfaces.Simultaneously because the factor of wire icing causes waving of lead generation under the effect of wind-force.According to the characteristics of waving, along the sinusoidal wave big wave amplitude motion of line direction system, horizontal line road direction is asymmetric elliptical motion.Therefore conductor galloping and mima type microrelief, micro climate are relevant, and be relevant with wind speed, wind direction, temperature, humidity that nature constantly changes, relevant with line alignment, relevant with the shaft tower height, relevant with the arrangements of conductors mode, this waved improvement have many enchancement factors.The harm that conductor galloping leads to mainly shows tripping operation, has a power failure, and hinders, disconnected lead and gold utensil, parts are impaired and fall several respects such as tower.
Variable thickness sample according to windward side, overhead transmission line conductor surface icing, be easy to produce eccentric icing, under the excitation of wind-force, can produce reverse poor, thereby from waving, self produces the source of waving, adopt inter-phase spacer to be installed between adjacent two phase conductors to this, damping action is played in the motion of adjacent wires, can suppress to wave generation or control the scale of waving, slacken and wave intensity, reached the optimum efficiency that inhibition is waved.
But products such as the inter-phase spacer that uses, two parallel wielded-proof device, off resonance pendulum, anti-dance whip have all played certain inhibition and have waved effect at present, but little to the generation effect that suppresses to wave, and can not satisfy the specification requirement under the complicated weather condition.
Summary of the invention
The purpose of this utility model provides a kind of compound inter-phase spacer, and it is little to the effect that suppresses to wave to have solved prior art, can not satisfy the problem of specification requirement.
The technical scheme that the utility model adopted is that a kind of compound inter-phase spacer comprises that three free strand formula wire clamps are connected successively with three groups of composite insulators, constitutes the triangle fixed structure.
Compound inter-phase spacer of the present utility model, its characteristics also are: the structure of described each free strand formula wire clamp is, comprises wire clamp, an end of wire clamp is provided with the wire clamp mouth, is provided with a circle rubber insulation in this wire clamp mouth; Wire clamp by bearing pin two with to be connected link plate one end hinged, connect the link plate other end and be provided with two groups of bearing pins one, every group of bearing pin one is hinged with one group of strand formula ball bowl or one group of common connector respectively, and when using strand formula ball bowl, the other end of every group of strand formula ball bowl is provided with installation head.
The beneficial effects of the utility model are, prevent that effectively overhead transmission line conductor is external force (mainly being wind-force) effect waving of generation down, to guarantee that any direction all can keep axially loaded relatively to two phase conductors under the state waving, it is being held main traverse line and is partly adopting the abrasive rubber wrapped pad to carry out soft fixing, to prevent fraying to lead.
