Description
Technical field:
The utility model relates to a kind of Novel copper-aluminium compound transition row, is a kind of conductor material of electric power transfer, belongs to the fields such as power system transformer substation, transformer, reactor.
Background technology:
In the power equipment such as transformer, reactor of electric power transformer substation system, (one end is copper to general employing copper to aluminum adapter bar, one end is aluminium) connected mode, there are two shortcomings in this product: 1), copper to aluminum adapter bar adopt aluminum plate material and copper sheet material dissimilar metal correspondence welding form, because copper aluminium two kinds of metals are difficult to welding especially, even if integral by being welded to connect, its weld defect is many, bulk strength is low, insecure, in installation connects, easily make aluminium and copper material part split in commissure, the reliability of quality is not high.2), one end adopts full copper to do conductor, copper material consume more, cost is high, electric current by time commissure resistance comparatively large, easily generate heat, reduce conduction transfer efficiency.
In recent years, transformer and reactor arrangement also there is a kind of copper to aluminum adapter bar of double-sided copper-clad bringing into use, it covers one deck copper strips or Copper Foil on the upper and lower surface of aluminium sheet, and the use of this product reduces entreprise cost, solves the technical problem of copper aluminium butt welding difficulty.But, there is security incident in its major defect: 1), coper-coated end only has upper and lower surface to have copper, and two sides do not cover copper, easily corona discharge occur; 2), cover copper section both sides and belong to Cu and Al combination section, in atmosphere exposed, improve the possibility of electrochemical corrosion; 3), to cover copper to aluminum adapter bar intensity low, in use easily produces distortion.
Above-mentioned copper to aluminum adapter bar and double-sided copper-clad copper to aluminum adapter bar, also exist deficiency separately, needs to improve.
Utility model content:
The purpose of this utility model provides a kind of Novel copper-aluminium compound transition to arrange for above-mentioned Problems existing, its structure is simple, easy to operate, certain compression can be born and still can keep normal temperature and mechanical strength after repeatedly cold cycling, make electric equipment more steady, safe operation, substantially increases power supply reliability.
Above-mentioned object is realized by following technical scheme:
A Novel copper-aluminium compound transition row, comprises one section of copper clad aluminum wire, and one end of described copper clad aluminum wire or two ends are connected with aluminium row, and described copper clad aluminum wire comprises the layers of copper being positioned at middle aluminium core and being coated on described aluminium core surrounding.
Described Novel copper-aluminium compound transition row, passes through between described aluminium core and described layers of copper together with high temperature rolling composite joint, forms metallurgical binding, gapless.
Described Novel copper-aluminium compound transition row, described copper clad aluminum wire and described aluminium arrange between by being welded together.
Described Novel copper-aluminium compound transition row, described copper clad aluminum wire is identical with the shape size of the cross section that described aluminium is arranged.
Beneficial effect:
Copper clad aluminum wire of the present utility model adopts the structure of surrounding layers of copper metallized aluminum core, avoid the generation of the problem such as corona discharge, chemical corrosion, reliable operation, and copper clad aluminum wire of the present utility model adopts the structure of surrounding layers of copper metallized aluminum core that welding production can be made convenient, bulk strength is high, and with low cost, there is wide market prospects and huge market potential.

Embodiment:
As shown in Figure 1, of the present utility model a kind of Novel copper-aluminium compound transition row of the present embodiment, comprise one section of copper clad aluminum wire, one end of described copper clad aluminum wire or two ends are connected with aluminium row, as shown in Figure 2 and Figure 4, copper clad aluminum wire described in the utility model comprises the layers of copper being positioned at middle aluminium core and being coated on described aluminium core surrounding.Its cross sectional shape can be wholecircle limit or fillet, and Fig. 2 is the cross section, wholecircle limit of copper clad aluminum wire, and Fig. 3 is that the aluminium in the cross section, wholecircle limit be connected with the copper clad aluminum wire in cross section, wholecircle limit is arranged.Fig. 4 is the copper clad aluminum wire of filleted section, and Fig. 5 is that the aluminium of the filleted section be connected with the copper clad aluminum wire of the filleted section of Fig. 4 is arranged.
Copper clad aluminum wire of the present utility model adopts special copper pipe and aluminium row carries out cold rolling compound, the great-deformation hot-rolled of high temperature 60% is combined with each other, and form very high bond strength, and layers of copper surrounding is evenly distributed.
Copper clad aluminum wire of the present utility model and aluminium are arranged and are welded together by form head to head, and welding process needs full weld, and carry out internal flaw test, and intensity reaches 100% matrix strength, namely define Copper-Aluminum compound transition row of the present utility model.
Technological means disclosed in the utility model scheme is not limited only to the technological means disclosed in above-mentioned technological means, also comprises and is equal to by above technical characteristic the technical scheme that replacement forms.Unaccomplished matter of the present utility model, belongs to the common practise of those skilled in the art.
