Abstract
The invention discloses an equal outer diameter welding method of cable conductors. A layered welding method is adopted to ensure all the conductors to be securely welded, thus ensuring the welding strength and the electrical property after welding. The layers are subjected to misplaced welding, the conductors are chamfered before welding, the face of weld is full of welding flux, the weld joint is easier to treat to have the same outer diameter as the conductors and each layer is treated in such a manner and is subjected to misplaced welding; and therefore the outer diameter can not be enlarged due to superposition after the whole conductors are welded and the overall effect after welding is better.
Description
Technical field
The present invention relates to external diameter welding methods such as a kind of cable conductor.
Background technology
Can run into the problem of cable conductor conductor tab when producing high pressure and extra-high-tension cable always.What generally adopt now is that two conductor clampings are docking together on two electrode dops, and the outside adds porcelain bushing protection, then, loads big electric current for two electrodes, makes the local high temperature that produces of conductor, and conductor is melted to press together and forms welding.As publication number is the disclosed Chinese invention patent of CN101299358A " method for welding whole core of cable twisting conductor ", the major defect of this method is impossible all firm welding when being the conductor welding, therefore can cause weld strength not ideal, easily broken, and the defective phenomenon of resistance appears in electric property instability easily; Pad place external diameter is bigger than normal, and the effect of finishing is undesirable.

Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is further described.
External diameter welding methods such as cable conductor of the present invention may further comprise the steps:
It is neat with the cable core end cut at first will to need the cable core A that welds and cable core B to be separately fixed on two anchor clamps on the operating desk, to tighten with copper wire respectively on the both sides of cut point before the cutting, with prevent cable core when the cutting and cutting afterwards conductor is loose opens;
On cable core A, inwardly measure 150mm, tighten with copper wire, then the 3rd layer of monofilament 13 usefulness hand are upwards turned up (as shown in Figure 1) one by one along pitch in the position of measuring from the end;
The second layer at cable core A is inwardly measured 30mm from the end, at this place this layer of copper monofilament cut off, and cuts off the back and measures 90mm inwards from cut-out point, tightens with copper wire at the place of measuring, and second layer monofilament 12 is upwards turned up one by one along pitch with hand equally;
Ground floor at cable core A is inwardly measured 90mm from the end, at this place this layer monofilament 11 cut off;
Nexine at cable core A is inwardly measured 60mm from the end, at this place this layer conductor 10 cut off;
Inwardly measure 90mm the 3rd layer of cable core B from the end, this layer monofilament 23 cut off (as shown in Figure 2) at this place;
The second layer at cable core B is inwardly measured 60mm from the end, at this place this layer monofilament 22 cut off;
Ground floor at cable core B is inwardly measured 50mm from the end, this layer monofilament 21 upwards turned up one by one along pitch with hand then;
Nexine at cable core B is inwardly measured 30mm from the end, at this place this layer conductor 20 cut off;
With file or sanding machine the end conductor of cable core A and cable core B and monofilament are all repaiied the inclined-plane that is rasped to the 45-60 degree;
The welding nexine, cable core A is head to head aimed at (as shown in Figure 3) with the conductor of cable core B, between keep the distance of 1～2mm, with oxygen welding and silver solder the butt joint conductor is filled welding, it is smooth to carry out reconditioning with sanding machine after welding, with vernier caliper measurement weld diameter, must guarantee that weld diameter and conductor diameter are equal to;
The monofilament that cable core B ground floor is turned up restores, and slowly rotates along its twisted wire direction then, aligns respectively with the ground floor monofilament of cable core B until cable core A, with silver solder welding is filled on the inclined-plane equally, and it is smooth to carry out reconditioning with sanding machine after welding;
The monofilament that the cable core A second layer is turned up restores, and slowly rotates along its twisted wire direction then, aligns respectively with the second layer monofilament of cable core B until cable core A, with silver solder welding is filled on the inclined-plane equally, and it is smooth to carry out reconditioning with sanding machine after welding;
The 3rd layer of monofilament of turning up of cable core A restored, slowly rotate along its twisted wire direction then, align respectively with the 3rd layer of monofilament of cable core B until cable core A, with silver solder welding is filled on the inclined-plane equally, it is smooth to carry out reconditioning with sanding machine after welding.
The present invention adopts the method for layering and dislocation to weld.Each layer that is about to conductor tied up by the successively first strip off in different positions, the length of both sides conductor is accepted or rejected and is formed complementation, guarantee the length unanimity of every layer of conductor splice, successively weld from the bottom of the inside with silver soldering, welding preceding two ends conductor all polish weld bond and is convenient to pile up scolder, every layer want reconditioning smooth after welding after weldering outside one deck again, gradually toward outer, it is outer that nexine welds weldering again from nexine.Every layer weld after, the particular manufacturing craft circumference different with size press compacting along the conductor direction of lay.Like this, guaranteed that the external diameter of every layer of conductor is consistent with original bonding conductor external diameter, and every lead is all soldered firmly, and not welded together between every layer.After all welding, use the mould with external diameters such as conductors to press compacting along the conductor direction of lay again, the conductor diameter after guaranteeing to weld is consistent with the conductor diameter of linkage section.
The method that the present invention takes layering to weld respectively guarantees that every conductor is all welded securely, thereby has guaranteed the electric property of weld strength and postwelding.Owing to be the dislocation welding between every layer, and conductor has been done chamfered before the weldering, the solder side scolder is fuller, more easily handle to the same with conductor diameter the commissure, all does processing like this for every layer, and adding is dislocation, therefore, after whole conductor welding was finished, external diameter can not cause because of stack causes the increase situation, and the postwelding whole structure is better.
