When split conductor surface forms eccentric icing, under the effect of extraneous wind-force, when lift is big caused by conductive line surfaces
When windage and wire are conducted oneself with dignity, wire transverse direction aerodynamic unstability is caused；Resistance is reversed when torsion caused by conductive line surfaces is more than wire
During power, wire torsional buckling is caused；Conductor galloping is caused under both unstability characteristic interactions.Under the same terms, work as wire
Upper installation the utility model proposes suppression turn round device when, it is smaller that the windage piece of device foreign aid reverses damping, each under wind-force effect
Windage piece is swung around bar 8 is limited so that the uniformity and uniformity of installation place wind field are interfered, while have influence on conductive line surfaces
The stability of aerodynamic parameter reduces the probability of unstability of shaking that laterally relaxes；Revolved further, since the wire holder of device center section is standby around axle
The ability turned, this reduces the torsional resistance of single conductor to a certain extent, when the effect of the wind-force of icing sub-conductor 12 is lower caused
When moment of torsion is more than single conductor torsional resistance, sub-conductor 12 rotates around central shaft, and it is whole that this reduces split conductor to a certain extent
Body moment of torsion, the probability for reducing split conductor entirety torsional buckling is played, play a part of suppressing wire entirety torsional buckling.This dress
That puts installs and uses, and can reduce overall laterally relax of split conductor simultaneously and shake and torsional buckling probability, so as to reach anti-dance effect.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those within the art that,
It can still modify to the technical scheme described in previous embodiment, either to which part or all technical characteristic
Equivalent substitution is carried out, and these are changed or are replaced, and the essence of appropriate technical solution is departed from the utility model embodiment
The scope of technical scheme.
