Abstract
The utility model relates to a 750kV reinforced wear-resistant four-split spacer which comprises a framework, wire clamp bodies and wire clamp cover plates. The middle of the framework is configured to be integral centrums which are separately in cooperation with each other in a concave and convex manner, wherein two centrums and taper holes are arranged in one framework; the centrums and taper holes are in mutual cooperation and lock each other when two frameworks are matched together; four corners of each framework are provided with the wire clamp bodies and cross shafts which are fixed by bolt assemblies; a rubber gasket is arranged between each wire clamp body and each wire clamp cover plate, and the wire clamp body and the wire clamp cover plate are fixed with an inserted hinge. The beneficial effects of the 750kV reinforced wear-resistant four-split spacer are that since a conical surface cooperation manner is adopted, the overall performance of the spacer framework is substantially improved, torsion resistance torque is increased by over two times than that of a conventional spacer; and in the aspect of wear resistance, a method of overall die casting is adopted as usual for process, and thus no new process is added, the cost and weight barely change, and the wear-resistant capability remains very strong.
Description
Technical field
The utility model relates to the conductor spacer field, is mainly that the 750kV in a kind of 750kV of being applied to transmission line conductors on quad bundled Structural Engineering strengthens wear-resistant formula quadripartion conductor spacer.
Background technology
2011, Xinjiang Electric Power Transmission ﹠ transformation Company is breathing out the two wires to telling, is finding the lead spacer serious wear when Dun Haxian walks ray examination, is having 940 covers loosening, these section natural environment characteristics are famous " Bai Lifeng districts ", strong wind all the year round, the bad weather such as heavy ice snow, strong sand dust zone; By the person skilled analysis, this lead spacer exists anti-unbalance tension force and the bad defective of wear resistance.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of corrosion resistant, abrasion-resistance is strong, mechanical strength is good 750kV to strengthen wear-resistant formula quadripartion conductor spacer.
The purpose of this utility model is completed by following technical solution, it comprises framework, wire clip body, wire clamp cover plate, the centre of described framework is set as the concavo-convex separately cooperation of whole centrum, establish two centrums and taper hole on a framework, when two frameworks fit together the locking mutually that cooperatively interacts of postcentrum and taper hole; Four corners of described framework are fixed with wire clip body and cross axle by bolt assembly, are placed with rubber blanket between wire clip body and wire clamp cover plate, and insert fixing by joint pin.
As preferably, described cross axle is embedded on wire clip body, and symmetrical with the wire clip body up and down; This wire clip body is provided with at the end near the wire clamp cover plate and pins pin.
As preferably, described wire clip body is being equipped with four rubber columns with the framework junction, and this rubber column will be lower than two platforms up and down of cross axle, and is distributed in four nooks of cross axle.
The beneficial effects of the utility model are: strengthen tapered the fit system that wear-resistant formula quadripartion conductor spacer adopts, the overall performance of conductor spacer framework has just improved greatly like this, than the twisting resistance of general interval rod apart from increase more than 2 times; Aspect wear-resistant, adopt equally the integral die-cast form at process aspect, so comparing, operation do not increase, and cost and weight almost do not change yet, and abrasion-resistance is very strong characteristics also.

Embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed introduction: as shown in accompanying drawing 1,4, the utility model comprises framework 1, wire clip body 2, wire clamp cover plate 4, the centre of described framework 1 is set as the concavo-convex separately cooperation of whole centrum, establish on a framework 1 two centrums 11 with taper hole 12(as shown in accompanying drawing 2,3), when two frameworks 1 fit together the locking mutually that cooperatively interacts of postcentrum 11 and taper hole 12; Four corners of described framework 1 are fixed with wire clip body 2 and cross axle 7 by bolt assembly 8, and carry out riveting in the bolt end, crackle can not occur after riveting.4 of wire clip body 2 and wire clamp cover plates are placed with rubber blanket 3, and insert fixingly by joint pin 9, and fill with ashbury metal, then the aperture are struck little with hammering into shape, and joint pin 9 can not be gone here and there out.
Described cross axle 7 is embedded on wire clip body 2, and symmetrical Shang Xia 2 with wire clip body; This wire clip body 2 is provided with at the end near wire clamp cover plate 4 and pins pin 5.Wire clip body 2 can swing ± 12 ° along the tangential direction of wire, and the fair line direction swings ± 8 °; The opening of wire clamp cover plate 4 should be able to guarantee that wire packs into smoothly.Being applicable to wire type is: JLK/G2A-630(720)/45 wires.Described wire clip body 2 is being equipped with four rubber columns 6 with framework 1 junction, and this rubber column 6 will be lower than two platforms up and down of cross axle 7, and is distributed in four re-entrant angle 71 places of cross axle 7, and askew, the state such as turn round, sprain of not having exists.
When being subjected to unbalanced tensile force between wire, conductor spacer is twisted, cause the stressed serious plate face fracture of framework veneer.And strengthen tapered the fit system that wear-resistant formula quadripartion conductor spacer adopts, will be delivered to another side plate to the power of a plate, make two veneers be merged into one, the overall performance of conductor spacer framework has just improved greatly like this, and detect research institute at Zhejiang China electrical equipment material the iceproof conductor spacer carried out the anti-torsion vibration fatigue test, result of the test than the twisting resistance of general interval rod apart from increasing more than 2 times.Aspect wear-resistant, adopt equally the integral die-cast form at process aspect, so comparing, operation do not increase, cost and weight almost do not change yet, but the economic benefit of bringing will be can not ignore, and the price of a cover conductor spacer is up to a hundred, all needs several thousand covers on every 500kV transmission line.When wire covers heavy ice or judder, what directly impact damaged will be conductor spacer, if conductor spacer is damaged, the whole piece circuit all can be out of service so, and this will bring huge direct and indirectly loss.
The utility model is not limited to above-mentioned execution mode; no matter do any variation on its shape or material formation; every employing structural design provided by the utility model is all a kind of distortion of the present utility model, all should think within the utility model protection range.
