Abstract
The invention discloses a rectangular conductor. A body oxide layer (the oxide layer is very thin with little resistance) retaining copper and aluminum alloy is proposed to act as an isolation layer to prevent electrochemical reaction. The copper and the aluminum alloy (such as aluminum and magnesium alloy and rare earth aluminum alloy) are combined through overlapping. By splitting of the isolation layer, the copper and the aluminum alloy form two relatively separate conductors but equal in potential without generation of electromagnetic interference between each other, and a uniform effect of current density distribution is greatly increased. The rectangular conductor is suitable for buses and transformers at various voltage levels.
Description
Technical field
The present invention relates to a kind of rectangular conductor and be applicable to the bus of various electric pressures, the conductor of transformer.
Background technology
The conductor industry of existing bus, transformer, in order to improve ampacity, to fall cost, has proposed copper clad aluminum wire, multiple fission copper or aluminium busbar.But do not find a way that more produces effect and fall cost, improve ampacity.It is the conductor that the insulation isolation is arranged between copper, aluminium, copper cover aluminum, copper aluminium that the conductor of above-mentioned series products adopts, its shortcoming:
1. the copper ampacity is little, temperature rise, and cost is high.
2. the aluminium ampacity is little, temperature rise, the aluminium conductance with copper than relative poor and easy oxidation.
3. the copper cover aluminum ampacity is little, temperature rise, copper cover aluminum complex process, be metallurgical binding (being used in conjunction with of prior art copper and aluminium must be metallurgical binding, and not so electrochemical reaction is arranged), the adhesiveness of copper aluminium is that copper and aluminium are not stratified, be an integral body, electric current distribution is inhomogeneous.Prismatic copper bar is compared with copper clad aluminum wire, and copper bar is larger than copper clad aluminum wire ampacity, and waste and old copper clad aluminum wire is in recovery, and copper aluminum separation technique complexity is seriously polluted.
4. the shortcoming of multiple fission copper or aluminium busbar: ampacity is little, and temperature rise having the insulation isolation between copper aluminium, and the reaction of copper Al electrochemical has solved, but copper, aluminium are two independent conductors, equipotential not, and the electromagnetic field phase mutual interference between two conductors, reduce ampacity mutually.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art; (oxide layer is very thin for the bulk oxidation layer of proposition reservation copper and aluminium alloy; resistance is very little) as isolated protective layer; prevent electrochemical reaction; it is the overlap joint combination that copper coordinates with aluminium alloy (as almag, rare earth aluminium alloy), and by the division of isolated protective layer, copper, aluminium alloy form two relatively independent but conductors that current potential equates; can not produce electromagnetic interference each other, the even effect of electric current distribution improves greatly.
Realize the technical scheme of the object of the invention: a kind of rectangular conductor of the present invention is to adopt two copper strips folder aluminum alloy strips (aluminum alloy strip is in centre) for: rectangular conductor, with the bulk oxidation layer of copper strips, aluminum alloy strip as separator.Above-mentioned conductor according to electric pressure need can be on conductor additional insulating barrier or shield dielectric layer.
The invention has the beneficial effects as follows: a kind of rectangular conductor is to use the bulk oxidation layer of copper and aluminium alloy as isolated protective layer; it is the overlap joint combination that copper coordinates with aluminium alloy, and the even effect of electric current distribution is than between copper, aluminium, copper cover aluminum (combination of the copper metallurgy of aluminium), copper aluminium, having the conductor of insulation isolation good.Prismatic copper bar is compared with copper folder aluminium alloy row, and copper folder aluminium alloy row ampacity is large, and temperature rise is low.The formed conductor of a kind of rectangular conductor is larger than the conductor ampacity that the insulation isolation is arranged between copper, aluminium, copper cover aluminum, copper aluminium, and temperature rise is low.The application that metal oxide layer is done isolated protective layer has realized improving the energy-saving effect that ampacity, temperature rise are low, fall cost.
