Abstract
The invention discloses a conductor welding method for a multicore and multilayer conductor cable. Firstly, one end of the cable, which requires to be jointed, is stripped off so that a plurality of layers of conductors are exposed, and the layers of conductors are cut to be short layer by layer from inside to outside; one end of another corresponding cable is stripped off, conductors of the cable are cut to be short correspondingly, then the conductors of the two cables are connected one to one and are welded in a seam welding form from the inner layer to the outer layer, the welding temperature is controlled to be 800-950 DEG C, sliver solders are embedded into the burning conductors, and borax is smeared; a thin copper wire is untied when each layer is welded, and then the next layer is welded after the heaved parts are repaired to be smooth by a file till the cores of all the conductors are welded. Compared with the existing jointing technology, the conductor welding method is firm in welding, stable in structure, good in electrical property and smooth in appearance.
Description
Technical field
The present invention relates to a kind of electric wire, specifically is a kind of conductor welding method of multicore multi-layer conductive cable.
Background technology
The joint of power cable conductor divides good multiple, and a kind of is that single conductor is bumped to connect by the silver soldering sheet and is welded into an integral body, and this joint is applicable to low-voltage cable; Second kind is non-compact conductor integral solder below 10, need be by silver solder and borax, and the phenomenon that the weld conductor resistance increases can appear in this method, and greater than the conductor more than 10, the welding difficulty is bigger; The third is to utilize the electric cable accessories transition joint or utilize the copper sheathing crimping, and this method is applicable to the job site operation, but the tensile strength of welding position is no more than 85% of whole conductor tensile strength.
Summary of the invention
Technical problem to be solved by this invention provides a kind of multicore, multi-layer conductive welding method of being applicable to; Claim the dislocation welding again, it is specially adapted to the continuous welding of factory's length sea electric power cable conductor, and no matter conductor is to press; Also be non-pressing, all can take the method to weld.
The conductor welding method of a kind of multicore multi-layer conductive cable of the present invention, it may further comprise the steps:
1) at first cable is needed an end strip off of joint, exposes multi-layer conductive,
2) the longest according to middle conductor, each layer of brachymemma conductor successively from inside to outside,
3) another corresponding cable one end of strip off exposes multi-layer conductive, and is the shortest according to middle conductor, each layer of brachymemma conductor successively from outside to inside, and the length and step 2 of intercepting conductor) to intercept conductor length in the cable corresponding one by one,
4) afterwards with the conductor of two cables one by one to connecting, from the internal layer to the skin, successively weld with the mode of seam weldering, welding temperature is controlled at 800 ℃--950 ℃, and embed silver solder, smear borax at the conductor place of burning heat;
5) every welding one deck then will be untied thin copper wire, with file with the protruding part repair smooth after, the following one deck of welding finishes up to whole conductor thread cores welding again.
Above-mentioned steps 2) difference with each layer of step 3) intercepting process intercepted length is identical, and after the strip off of each layer conductor, tightens with thin copper wire, prevents to flick.
As improvement of the present invention, above-mentioned steps 4) in the process, after the skin welding, with file with the protruding part repair smooth after, enclose along welding seam part Bit Grinding one with fine sandpaper again, remove copper powder impurity, weld internal layer afterwards.
Beneficial effect of the present invention:
1, reduces the welding position D.C. resistance to greatest extent.
2, improve the firmness of welding position to greatest extent; The tensile strength of welding position reaches more than 90% of whole conductor tensile strength.
The smoothness and the roundness that 3, can keep the welding position, phenomenons such as no burr, sharp edge.
4, keep connection stable, can stand fault current and impact.
5, after the long-time running, contact resistance is not more than cable core body 1.2 times with length resistance.
6, have certain mechanical performance and antiseptic property.
7, with existing joint compared with techniques, firm welding, Stability Analysis of Structures, electrical property is good, outward appearance is level and smooth.
Embodiment
A kind of conductor welding method of multicore multi-layer conductive cable, it may further comprise the steps:
1) at first cable is needed an end strip off of joint, exposes multi-layer conductive.
2) the longest according to middle conductor, each layer of brachymemma conductor successively from inside to outside, the difference of each layer intercepted length is identical.
3) another corresponding cable one end of strip off exposes multi-layer conductive, and is the shortest according to middle conductor; Each layer of brachymemma conductor successively from outside to inside; And the length and step 2 of intercepting conductor) to intercept conductor length in the cable corresponding one by one, after the strip off of each layer conductor, tightens with thin copper wire, prevent to flick.
4) afterwards with the conductor of two cables one by one to connecting, from the internal layer to the skin, successively weld with the mode of seam weldering, welding temperature is controlled at 800 ℃--950 ℃, and embed silver solder, smear borax at the conductor place of burning heat.
5) after skin welding, with file with the protruding part repair smooth after, enclose along welding seam part Bit Grinding one with fine sandpaper again, remove copper powder impurity, weld internal layer afterwards.Every welding one deck then will be untied thin copper wire, with file with the protruding part repair smooth after, the following one deck of welding finishes up to whole conductor thread cores welding again.
The above only is a preferred implementation of the present invention, should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also make some improvement, and these improvement also should be regarded as protection scope of the present invention.
