Description
Technical field
The present invention relates to a kind of power line lead do not stress connect wrap up in general formula parallel groove clamp, the strain insulator be applicable in the transmission line of electric power system, distribution line, low-voltage circuit cross draw that wire jumper connects, branch draw connect, distribution transformer draws lower connection, house lead in draws lower connection and electric substation, factory's distribution the various connections that do not stress of electrical lead.
Background technology
At present, power line lead does not stress connection, generally uses parallel groove clamp and T-shape cable clamp, parallel groove clamp and T-shape cable clamp contact resistance are large, linkage interface galvanic corrosion wound is fast, time have power circuit burn line-outage contingency occur, be the weak link of electrical network, Ye Shi accident potential.For replacing parallel groove clamp and T-shape cable clamp, C shape wire clamp, H-shaped wire clamp, wedge clamp, fusiformis wire clamp, the stress wire clamp of nearly more than ten years invention both at home and abroad, wrap up in binding clip etc., what have solves above-mentioned the deficiencies in the prior art because of thorough, what have is not convenient because of installing/dismounting, or expensive, the more than ten years are not all widely accepted and promote.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of safe and reliable, good connecting effect be provided, operation is easy, use cost is low power line lead do not stress connect wrap up in general formula parallel groove clamp.
Object of the present invention can be realized by following technical scheme:
Power line lead do not stress connect wrap up in general formula parallel groove clamp, the parallel groove clamp be combined to form by parallel groove clamp lower plate, parallel groove clamp train wheel bridge and parallel groove clamp fishbolt forms, have in the clamping chamber between parallel groove clamp lower plate and parallel groove clamp train wheel bridge the bolt combined by parallel groove clamp fishbolt in tandem with parallel groove clamp train wheel bridge with parallel groove clamp lower plate together with and left and right is provided with the clamp body of the hyperbola of clamp groove.
Object of the present invention can also be realized by following technical scheme:
The present invention is provided with the mounting hole that the bolt that combines with parallel groove clamp fishbolt matches at the middle part of the clamp groove connector of the clamp body left and right sides, the clamp groove of the clamp body left and right sides is symmetrical arranged in the left and right sides of mounting hole.
The clamp groove of the left and right sides of the present invention is " H " font setting of 90-degree rotation, and the length of the upper lower groove of clamp groove matches with parallel groove clamp train wheel bridge and parallel groove clamp lower plate respectively.
Parallel groove clamp lower plate of the present invention and parallel groove clamp train wheel bridge are stainless steel or carbon steel, malleable iron, and the cell body of the clamp groove of the clamp body left and right sides is identical with by the material of electrical lead that clamps or akin material.
Clamp body of the present invention is copper or aluminium, rare earth aluminium alloy.
The cell body of clamp body of the present invention is the welding body of copper and rare earth aluminium alloy.
Cell body on the left of clamp body of the present invention and the cell body on right side are identical material or two kinds of different materials.
The present invention compared with prior art has following advantages:
1, the present invention sandwiches the hyperbolic line piece of a middle UNICOM by string in parallel groove clamp clamping space, the hyperbolic line piece of this middle UNICOM forms with the copper identical or close with electrical lead material, aluminium or copper-aluminium transition material etc. are special, effectively overcome that original parallel groove clamp contact resistance is large, linkage interface galvanic corrosion wound is fast, time have power circuit to burn shortcoming that line-outage contingency occurs.
2, the present invention is owing to adopting the rigid materials such as stainless steel, carbon steel, malleable iron to be made into parallel groove clamp on the one hand, the clamp body that the copper that another aspect material is softer and identical or close with being connected lead material, aluminium or copper-aluminium transition material are special, screwing clamp body in clamping process at parallel groove clamp can with the distortion of original parallel groove clamp in hyperbolia, after clamp body deformability can effectively, firm grip wire, good to ensure to connect.
3, clamping part (parallel groove clamp) is separated with wire connecting part (clamp body) by the present invention, whole wire clamp is made to require to reduce to the material of clamping part, because it is being not main conductive component, so it can adopt intensity high and the low common material of cost, the cost of clamping part and even whole wire clamp effectively can be reduced; Wire connecting part can change the parts of unlike material as required neatly on the other hand, meeting the demand connecting unlike material wire, so effectively can reducing the cost because converting whole parallel groove clamp material.Two can select identical with being connected wire or akin material as required easily.
4, adopt the present invention that clamping part (parallel groove clamp) will be made without the need to converting material, just can meet the needs connecting unlike material wire, realize the multiple change of wire clamp material with the change of entirety constant (parallel groove clamp), local wire connecting part (clamp body), meet different needs.
5, the present invention can facilitate and low cost the material of wire connecting part (clamp body) is changed to one is e and f is all aluminium or rare earth aluminum alloy material; Another is e and f is all copper material; Another is e is aluminium or rare earth aluminum alloy material, and f is copper material, carrys out satisfied different needs.
6, the present invention conveniently can realize the wire clamp material identical or the most close with wire, galvanic corrosion wound is not produced when making it be energized, and contact resistance is little, connect safe and reliable, can not only be used for transmission line, distribution line, low-voltage circuit strain insulator cross draw wire jumper connect, and power circuit branch can also be used for or lead-in wire " T " connects, have simultaneously save aluminium or copper material, cost low, feature is easily installed.
7, the present invention adopts the hyperbolic line piece of middle UNICOM (clamp body) to be two circular arc arcs are carried on the back relative external arc be connected, it becomes main conductive component, not only convenient but also cost is low to its replacing, ten thousand changes are answered with the change of simple components, the effect that art is good for strength can be played, and the opening of clamp body outwardly, wire is installed convenient and swift.
