Description
Technical field
The invention belongs to T & D Technology field, particularly the Schizoid lead spacer structural design of the anticorona characteristic at wire clamp place.
Background technology
Overhead transmission line is under the bad weather conditions such as glaze, strong wind, heavy snow severe snow, easily causing circuit leads, the phenomenons such as ground wire icing, windage yaw, ice-shedding cause that wire is alternate, relatively distance changes, cause electric discharge tripping operation between mutually alternate, phase ground, and after waving for a long time, make the damages such as line hardware, insulator, wire, shaft tower, cause the most serious power transmission accident.The bundle conductor of each electric pressure transmission line all will be used conductor spacer, and conductor spacer main application is the relative motion between siding stopping wire and the geometry that keeps under normal circumstances bundle conductor.The radical of pressing power transmission and transformation line grade and bundle conductor is different, and current used lead spacer can be divided into two, three, four, six, five types of using of eight wires.1000KV AC input transformation circuit bundle conductor generally adopts eight bundle conductor conductor spacers, and this best result that is also China adopts at present splits several bundle conductor conductor spacers.Along with the appearance of 1150KV electric pressure transmission line of alternation current, as a kind of mode of 1150KV UHV AC transmission technique, compact transmission line generally adopts ten binary fission wires.Traditional lead spacer is generally also comprised of hexagon framework, wire clip body and wire clamp cover plate, as shown in Figure 6, be a kind of structure of six-divided conductor spacing bar of routine, its wire clip body and framework junction are only fixed by a screw, stressed having some setbacks, easily causes the distortion of part even to destroy.Receiving in the powerful power of pullling situation easily looseningly, can not play good support fixation.Wire clamp and wire clamp cover plate face and face joint are right angle corner angle in addition, and radius of curvature is very little, sufficiently oily, cause wire clamp surface electric field intensity skewness, easily cause corona discharge.
Summary of the invention
The object of the invention is the problem existing for above-mentioned prior art, a kind of six-divided conductor spacing bar of anti-dizzy type is provided, and can be when there is stronger vibration in this structure, and whole system is stressed smooth and easy, the distortion that part can not occur destroys, and wire clamp place field intensity can not cause corona discharge simultaneously.
The object of the present invention is achieved like this: a kind of anti-dizzy type six-divided conductor spacing bar, comprise hexagon framework, six wire clamps that formed by wire clip body and corresponding wire clamp cover plate, it is characterized in that, the far-end of described wire clip body is by joint pin connecting clamp cover plate, and described framework outside is fixedly connected with equally distributed six wire clip bodies by cross axle sleeve; Described hexagon framework and six wire clip body near-end corresponding positions have arc-shaped slot, and described wire clamp near-end also with between the arc-shaped slot of framework is connected by bearing pin simultaneously; The far-end of described wire clip body is by joint pin connecting clamp cover plate.
Described wire clip body far-end can be class hemisphere, and outside is smooth surface, and inner side is half cinclides that wire is passed through, and the near-end of wire clip body has class square hole and the pin-and-hole that cross axle sleeve is installed, and middle part is provided with the bearing pin of fixing clamper lid; Wire clamp cover plate one end can be and the corresponding class hemisphere of wire clip body, and outside is smooth surface, and inner side is half cinclides that wire is passed through.
The arc angle of described arc-shaped slot is about 10 degree;
Between described wire clamp cover plate and wire clamp, can be provided with wire clamp rubber blanket.
Rubber column and packing ring can be set to increase damping between described cross axle sleeve and framework.
Cable is waved in order to prevent from using, and one end of described framework can arrange Anti-galloping device installing hole.
The invention has the beneficial effects as follows:
The present invention is aspect mechanical property, wire clip body near-end end with framework except being fixedly connected with by cross axle sleeve, also between time and framework, by bearing pin, be connected, thereby when producing great vibrations, overall structure allow wire clip body to produce Small-angle Rotation, thereby guarantee stressed smooth and easy, with tamper-proof bundle conductor, 2 fixing effects have been played simultaneously, can bear unbalanced tensile force, what while standing people on vibration and solid conductor, between sub-conductor, produce draws, pressure has firm grip to wire when normal operation or wire generation moment of torsion.
The present invention is aspect electrical characteristic, and wire clip body and the coupling of wire clamp cover plate are very tight, after having fixedly mounted, approximate spherical, the radius of curvature on each face is all enough large, and radius of curvature is enough large, guarantee being uniformly distributed of electric field, thereby avoided the generation of electric field sudden change and corona.
