Description

Wrap up in formula parallel groove clamp

Technical field

This utility model relate to a kind of power line lead do not stress connect wrap up in formula parallel groove clamp, it is adaptable to the strain insulator in the transmission line of electricity of power system, distribution line, low-voltage circuit cross draw wire jumper connect, branch draw connect, distribution transformer draws lower connection, house lead in draws lower connection and the various connections that do not stress of electrical lead of electric substation, factory's distribution.

Background technology

At present, the power line lead connection that do not stress commonly uses that parallel groove clamp and T-shape cable clamp, parallel groove clamp and T-shape cable clamp contact resistance are big, linkage interface galvanic corrosion wound is fast, time have power circuit burn line-outage contingency to occur, it is 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 ramp etc., that have because thoroughly not solving above-mentioned the deficiencies in the prior art, it is that have because installing/dismounting is not convenient, or expensive, the more than ten years are all without being widely accepted and promoting.

Summary of the invention

The purpose of this utility model is in that to overcome the deficiencies in the prior art, it is provided that a kind of safe and reliable, good connecting effect, operation are easy, use cost is low wraps up in formula parallel groove clamp.

The purpose of this utility model can be realized by following technical scheme:

Wrap up in formula parallel groove clamp, combined, by parallel groove clamp lower plate, parallel groove clamp train wheel bridge and parallel groove clamp fishbolt, the parallel groove clamp formed to form, clamping between parallel groove clamp lower plate and parallel groove clamp train wheel bridge chamber has the lower plate of bolt and the parallel groove clamp combined by parallel groove clamp fishbolt and parallel groove clamp train wheel bridge in tandem together with and left and right be provided with the clamp body of hyperbola of clamp groove. Its parallel groove clamp lower plate and about two width that parallel groove clamp train wheel bridge is setting symmetrical above and below and all equal clamping plate of anterior-posterior length, the clamp groove of the hyperbola of clamp body is corresponding with the clamp groove of parallel groove clamp lower plate and parallel groove clamp train wheel bridge, the cell wall of the clamp groove of clamp body is thin-walled body, and " H " font that the clamp groove of the clamp body left and right sides is 90-degree rotation is arranged.

The purpose of this utility model can also be realized by following technical scheme:

This utility model is provided with the mounting hole that the bolt with the combination of 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, and the left and right width of clamp body and anterior-posterior length are respectively less than or are equal to left and right width and the anterior-posterior length of clamping plate.

Clamp body of the present utility model is copper or aluminum, rare earth aluminium alloy, and cell body and the cell body on right side on the left of clamp body are identical material or material two kinds different.

This utility model compared with prior art has the advantage that

1, this utility model 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 is to adopt form special with the same or like copper of connected electrical lead material, aluminum or copper-aluminium transition material etc., effectively overcome that original parallel groove clamp contact resistance is big, linkage interface galvanic corrosion wound is fast, time have the shortcoming that power circuit burn line-outage contingency occurs.

2, the current blanket parallel groove clamp that this utility model is fabricated to owing to adopting the rigid materials such as rustless steel, carbon steel, malleable iron on the one hand, the clamp body that softer and same or like with the connected lead material copper of another aspect material, aluminum or copper-aluminium transition material are special, screwing clamp body in clamping process at parallel groove clamp can with original parallel groove clamp deformation in hyperbolia, wire can effectively, be firmly clamped, to ensure to connect well after clamp body deformability.

3, clamping part (parallel groove clamp) is separated by this utility model with wire connecting part (clamp body), 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 the common material that intensity is high and cost is low, can effectively reduce the cost of clamping part or even whole wire clamp; Wire connecting part can change the parts of unlike material as required neatly on the other hand, meets the demand connecting unlike material wire, so can be effectively reduced the cost because converting whole parallel groove clamp material. Two can select easily as required same or like with connected wire like material.

4, this utility model is adopted clamping part (traditional parallel groove clamp) will to be made without converting material, just can meet the needs connecting unlike material wire, realize the multiple change of wire clamp material with the change of overall constant (traditional parallel groove clamp), local wire connecting part (clamp body), meet different needs.

5, this utility model can facilitate and the material by wire connecting part (clamp body) of low cost to be changed to a kind of be the clamp body of the left and right sides be all aluminum or rare earth aluminum alloy material; Another is the clamp body of the left and right sides is all copper material; Another is the clamp body side of the left and right sides is aluminum or rare earth aluminum alloy material, and opposite side is copper material, meets different needs.

6, this utility model can conveniently realize wire clamp and wire is identical or the most close material, galvanic corrosion wound is not produced when making it be energized, and it is little to connect resistance, attachment security is reliable, can be used not only for transmission line of electricity, distribution line, low-voltage circuit strain insulator cross draw wire jumper connect, and can be used for power circuit branch or lead-in wire " T " connect, have simultaneously saving aluminium or copper material, cost is low, install feature easily.

7, this utility model adopts the hyperbolic line piece (clamp body) of middle UNICOM to be two circular arc arcs are carried on the back relative external arc be connected, it becomes main conductive component, to its replacing is not only convenient but also cost is low, 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 is outwardly, wire is installed convenient and swift.
