Abstract
The utility model relates to a copper-coated aluminum busbar and aluminum busbar brazing butt joint in busbar connection of electrical equipment. A copper-coated aluminum busbar is firstly milled to an aluminum product to serve as a welding surface, a copper-coated layer is removed, an aluminum busbar in need of butting is grooved, and an aluminum base brazing filler metal is added for brazing. According to the copper-coated aluminum busbar and aluminum busbar brazing butt joint, the problem of poor copper and aluminum welding properties is avoided, the deformation is small, the joint is smooth and attractive in appearance, and good electrical conductivity is achieved.
Description
Technical field
The utility model relates to busbar row in power equipment power supply and distribution and connects, and relates in particular to the banjo fixing butt jointing of a kind of copper clad aluminum wire, aluminium row soldering.
Background technology
Copper clad aluminum wire is a kind ofly to take aluminium as matrix, outer coated copper, between bi-material, form the bimetallic of metallurgical binding between permanent atom, it is the high-quality of copper to be stablized to the low-cost resource of electric conductivity and aluminium, the novel conductor material being integrated with lower contact resistance.Aluminium has many advantages as conductor material, but also has its intrinsic shortcoming: easily oxidation, contact resistance is large, can not weld with scolding tin.Aluminium displacement can be saved expensive copper for copper bar and copper clad aluminum wire, in connecting, power electronics industry bus can run into a difficult problem for copper aluminium welding, and soldering is ripe at present welding procedure between aluminium, good workpiece is assembled together by joint form with fixture to be surface clean, and solder is placed near play movement or between play movement.When workpiece and solder are heated to after a little higher than solder melting temperature, solder fusing (workpiece does not melt), and be inhaled into and be full of between solid-state workpiece gap by capillarity, the mutual diffusion dissolution of liquid solder and workpiece metal, forms soldered fitting after cooling.
Summary of the invention
The technical problems to be solved in the utility model is to provide the banjo fixing butt jointing of a kind of copper clad aluminum wire, aluminium row soldering, and copper, aluminium welding are changed into aluminium, aluminium welding.
The utility model solves the technical scheme that its technical problem adopts: first copper clad aluminum wire milling to aluminium is made to solder side, remove and cover copper layer, need the aluminium of docking to arrange groove, hole, fill aluminium base solder and carry out soldering.
For copper clad aluminum wire and aluminium, row is T shape syndeton, and the milling of copper clad aluminum wire welding ends is covered copper layer to aluminium and made solder side, and aluminium material surface has a little processing capacity, requires smooth; Aluminium row welding plane fluting, groove depth is no more than aluminium row thickness 1/3, the one side gap 0.5～5mm of groove width and copper clad aluminum wire thickness.
For copper clad aluminum wire and aluminium, row is bridging arrangement, and copper clad aluminum wire welding plane fluting is removed and covered copper layer to aluminium and make solder side, and aluminium material surface has a little processing capacity, requires smooth; Aluminium row welding plane is opened cylindrical void or perforate, can carrying out step by step according to aluminium row length, and the aluminium that is 3～20mm for thickness row, bar hole width is 2～25mm.
The utility model has been avoided the problem of copper aluminium welding poor performance, is out of shape littlely, and joint smooth and beautiful appearance, has good electric conductivity.
Accompanying drawing explanation
Below in conjunction with the described embodiment of accompanying drawing, the banjo fixing butt jointing of utility model copper clad aluminum wire, aluminium row soldering is described in further detail.
Fig. 1 is copper clad aluminum wire and aluminium row T shape syndeton cross-section cutaway view.
Fig. 2 is copper clad aluminum wire and aluminium row bridging arrangement cross-section cutaway view.
Fig. 3 is the T shape syndeton stereogram of Fig. 1.
The specific embodiment
It is embodiment that the utility model be take high voltage converter busbar and bus-bar, Fig. 1 shows the form of soldered seam groove, copper clad aluminum wire 1 welding ends milling to aluminium is made solder side, removal is covered after copper layer 1a smooth in aluminium material surface processing, and aluminium row 3 welding planes flutings are placed hard solders 2, and groove width is B, copper clad aluminum wire 1 welding ends is inserted in groove, by frock, fix, in flame or stove, after heating, solder 2 evenly fusing flows in weld seam.
Fig. 2 shows the another kind of form of soldered seam groove, copper clad aluminum wire 11 welding slabbing to aluminiums are made solder side, width is B, removal is processed smooth by aluminium bottom surface after covering copper layer 11a, aluminium row 33 welding planes are opened cylindrical void and are placed hard solder 22, copper clad aluminum wire 11 and aluminium row 33 laminatings, the wide B of cylindrical void aims at copper clad aluminum wire 11 groove width B, and solder 22 heat fused flow into weld seam and form soldered fitting.
The foregoing is only preferred embodiment of the present utility model; but not the utility model is done to any pro forma restriction; those skilled in the art can impose the various changes that are equal to and improvement on the basis of above-described embodiment; all equivalent variations of doing within the scope of claim or modification, within all should falling into protection domain of the present utility model.
