Abstract
The utility model discloses a rotary split spacer which comprises a regular polygonal frame, a rotary wire clamp and a fixed wire clamp. The rotary wire clamp comprises an outer wire clamp, an inner wire clamp arranged inside the outer wire clamp, and clench rubber embedded inside the inner wire clamp. A rotation mechanism is disposed between the outer wire clamp and the inner wire clamp. Through the rotation mechanism arranged between the outer wire clamp and the inner wire clamp, after being clenched by the clench rubber, a lead can rotate around an axis of the lead itself through the rotation mechanism when ice is formed on a surface of the lead or ice on the surface is thawing. Therefore, a windward side of the lead is changed, and continuous icing and continuous rotation are realized, so that uniform icing can be formed for the lead, a shape of the lead tends to be circular and is hardly irregular, air force load acted on the lead is weakened, and the whole split lead is not liable to swing. The rotary split spacer is suitable for extra-high-tension overhead power transmission engineering.
Description
Technical field
The utility model relates to the conductor spacing protector of a kind of ultra high voltage overhead power transmission engineering special use, more specifically relate to a kind of be installed in the UHV Transmission Engineering keep many roots conductor spacing, to reduce reactance between the wire uneven and prevent the lead spacer of waving.
Background technology
It is vast that China restores, China's hydropower resources and rich coal resources, and petroleum resources is few, so power supply architecture is take Coal-fired Thermal Power (60% ~ 70%) and water power (about 25%) as main.Water resource is reproducible clean energy resource, and the Hydropower Development resource is the road that must go of energy development.Hydroelectric resource development must combine with " transferring electricity from the west to the east ", and development is long apart from large capacity transmission.The coal resource distribution of China is also unbalanced, in explored 1,000,000,000,000 tons of reserves, 73% concentrate on Shanxi, Shan, illiteracy, peaceful, Gui Wu economizes (district), to build the large capacity thermal power plant of a part in these mining areas and send electricity to the coastal region in east China, this also needs to build the large capacity power transmission engineering of a collection of middle and long distance.At present China begun to take shape north, in, south three large passways for transmitting electricity, but along with the increase of carrying electric weight, this can not satisfy the demands far away, more how far must build the distance high-voltage corridor of transmitting electricity at a high speed, the conveying of the solution energy.
Along with constantly carrying out of UHV transmission line construction, the situation of waving for UHV transmission line, research suppresses the device of transmission line galloping, safe and stable operation to transmission line has realistic meaning, lead spacer is to keep many roots wire pitch, keeping the important power equipment of wire balance and reactive balance, also is the important gold utensil that prevents wire damaged in waving state.
It is generally acknowledged that the generation of transmission line galloping depends primarily on " three elements ", i.e. " the inhomogeneous icing of conductive line surfaces ", " suitable wind excitation " and " the easily line construction parameter of dance ".Wherein " inhomogeneous icing " is the main cause of line oscillation, also is most important external condition.Thus, if can stop wire to produce inhomogeneous icing, or effectively reduce the degree of irregularity of wire icing, then be beneficial to and prevent from waving.
The used most of lead spacer wire clamp of China's overhead transmission line is and the fixing damp type wire clamp that grips of sub-conductor at present.This conductor spacer is suppressing aspect transmission line aeolian vibration and the subspan oscillation certain effect is arranged, but this conductor spacer is unfavorable for the even icing of wire.Especially for bundle conductor, after sub-conductor produces eccentric icing, because the existence of wire clamp of conductor spacer grip, wire are difficult to produce the rotation around self axis, like this, eccentric icing will be more serious, form the inhomogeneous icing of the shapes such as fan-shaped, crescent, D shape, excitation forms positive feedback to inhomogeneous icing to wind, so that system capacity is gathered, final unstability causes waving, this also just bundle conductor with respect to the easier reason of waving of single conductor.
The utility model content
The purpose of this utility model is to provide a kind of rotary type cracking separation rod, and it can make the icing on the wire even by the relatively rotating of the outer wire clamp in the rotary type wire clamp and interior wire clamp, and prevents the phenomenon that waving appears in wire.
The solution that the utility model solves its technical problem is: a kind of rotary type cracking separation rod, the framework that comprises regular polygon, be hinged on the rotary type wire clamp on the framework and be fixed on fixed wire clamps on the framework, described rotary type wire clamp comprises outer wire clamp, the rubber of holding with a firm grip that is installed in the interior wire clamp in the outer wire clamp and embeds interior wire clamp, described outside line folder comprises the outside line cramping lid that outer wire clamp body and an end and outer wire clamp body are hinged, described interior lines folder comprises two interior wire clip bodies, wire clamp in forming after described interior wire clip body fastens is equipped with rotating mechanism between described outer wire clamp and the interior wire clamp.
As further improvement in the technical proposal, described rotating mechanism comprises the rotary axle box that is installed in interior wire clamp outer surface and the fixed hub that is complementary with rotary axle box, and described fixed hub is installed on the outer wire clamp.
As further improvement in the technical proposal, described fixed hub comprises the first fixed hub and the second fixed hub, and described the first fixed hub is fixed on the outer wire clamp body, and described the second fixed hub is fixed on the outside line cramping and covers.
As further improvement in the technical proposal, the end of described outer wire clamp body also is equipped with stopping means, described stopping means comprises several damping rubbers that are embedded in outer wire clamp body tip and the positive stop lug boss that is arranged on outer wire clamp body tip, and described positive stop lug boss is in same plane with the first boss and the second boss that are arranged on the framework.
As further improvement in the technical proposal, described framework is square or regular hexagon or octagon.
The beneficial effects of the utility model are: the utility model is by being equipped with rotating mechanism between wire clamp and the interior wire clamp outside, so after the rubber of holding with a firm grip is held wire with a firm grip, in conductive line surfaces icing or the thawing of surperficial icing, can pass through rotating mechanism, wire is can be around the rotation of self axis, thereby change the windward side of wire, so continuous icing, the result who constantly reverses, so that wire forms comparatively uniformly icing, it is circular that shape is tending towards, be difficult to form inhomogeneous shape, so that weakened the aerodynamic load that acts on the wire, make whole bundle conductor be difficult for waving.
The utility model is applicable in the ultra high voltage overhead power transmission engineering.
