Abstract
A method for using a copper and an aluminium alloy in cooperation. In the method, an oxide layer (the oxide layer is very thin and has a very low resistance) of a copper and aluminium alloy body is kept as an isolation protection layer to prevent an electrochemical reaction; the copper cooperates with the aluminium alloy (such as an aluminium magnesium alloy and a rare earth aluminium alloy) in an overlapping bond; and two conductors which are relatively independent but have the same electrical potential are formed by the copper and aluminium alloy through the disintegration of the isolation protection layer, so that there will be no electromagnetic interference therebetween, the distribution of the current density is uniform, and the effect is greatly improved. The method for using the copper and aluminium alloy in cooperation is applicable to conductors of electric wires and cables, buses, transformers, switches and sleevings of various voltage classes.
Description
METHOD FOR USINC COPPER AND ALUMINUM ALLOY IN
COOPERATION
BACKGROUND
Technical Field
The present invention relates to a method for using a copper and an aluminum alloy in cooperation, which applies to conductors of electric wires and cables, buses, transformers, switches, and sleevings of various voltage classes.
Related Art In the existing field of electric wires and cables, and buses, to improve a current-carrying capacity and reduce a cost, high strength copper-coated aluminum cable conductors, expanded steel-core aluminum stranded wires, hollow-core electric cables, high voltage hollow-core electric cables, electric cables of a combined conductor structure, and multi-splitting copper or aluminum buses are proposed. However, a method that is more effective in reducing a cost and improving a current-carrying capacity has not been found yet. Conductors used in the foregoing series of products include a copper conductor, an aluminum conductor, a copper-coated aluminum conductor, or a conductor with insulation between copper and aluminum, which have the following disadvantages: (1) Copper has a low current-carrying capacity, a high temperature rise and a high cost.
(2) Aluminum has a low current-carrying capacity, a high temperature rise and a relatively weak electric conductivity compared with copper, and is easily oxidized.
(3) Copper-coated aluminum has a low current-carrying capacity and a high temperature rise, where aluminum coating with copper is a complex process of metallurgical bonding (in the prior art, use of copper and aluminum in cooperation must be in a manner of metallurgical bonding; otherwise, an electrochemical reaction may occur), adhesion performance of copper to aluminum causes the copper and the aluminum not to separate but to form into a whole, and current density is distributed unevenly. A copper wire has a higher current-carrying capacity than a copper-coated aluminum wire that has a same diameter, and a copper-coated aluminum cable is less energy-saving than a copper cable that has a same diameter. in addition, during recovery of waste copper-coated aluminum wires and cables, the process of copper and aluminum separation is complex and a severe pollution is caused.
(4) Disadvantages of a multi-splitting copper or aluminum bus include: a low current-carrying capacity and a high temperature rise; in addition, although a problem of an electrochemical reaction of copper and aluminum is solved by insulation between copper and aluminum, copper and aluminum are two independent conductors that have different electric potentials, and therefore, mutual interference occurring between electromagnetic fields of the two conductors causes reduction of current-carrying capacities of the both conductors.
SUMMARY
An objective of the present invention is to overcome disadvantages of the prior art, and propose retaining an intrinsic oxide layer of a copper and that of an aluminum alloy as 1 5 insulation protective layers, to prevent an electrochemical reaction, and bonding the copper and the aluminum alloy (such as an aluminum-magnesium alloy, and a rare earth aluminum alloy) in an overlapping manner for cooperation. By means of disintegration of the insulation protective layers, the copper and the aluminum alloy form two conductors that are independent of each other but have a same electric potential. Electromagnetic interference does not occur between the two conductors, and current density is evenly distributed, thereby significantly improving effects.
To achieve the objective of the present invention, the technical solution is as follows. A method for using a copper and an aluminum alloy in cooperation in the present invention is applied to: (1) a circular conductor using a copper as an exterior conductor and an aluminum alloy as an interior conductor, where an intrinsic oxide layer of the copper and that of the aluminum alloy are used as insulation protective layers, and structures of the conductor include copper-sheathed aluminum alloy bar (for a bar, a diameter thereof is larger; and for a wire, a diameter thereof is less than 5 mm), copper-sheathed aluminum alloy tube, copper-stranded aluminum alloy wire, expanded copper-stranded aluminum alloy wire, copper-stranded steel-core aluminum alloy wire, and expanded copper-stranded steel-core aluminum alloy wire; and (2) a rectangular conductor with a copper on an exterior thereof and an aluminum alloy strip (sheet) between the coppers, where an intrinsic oxide layer of the copper and that of the aluminum alloy strip (sheet) are used as insulation layers. The foregoing conductors may be provided with an insulation layer or a shielding insulation layer on an exterior thereof according to voltage class demands.
The present invention has the following advantageous effects: according to the method for using a copper and an aluminum alloy in cooperation, an intrinsic oxide layer of a copper and that of an aluminum aHoy are used as insu'ation protective layers, and the copper and the aluminum alloy are bonded in an overlapping manner for cooperation, where current density is evenly distributed, and effects are better than those of a copper conductor, an aluminum conductor, a copper-sheathed aluminum (metallurgical bonding of copper and aluminum) conductor, and a conductor with insulation between copper and aluminum: (I) when compared with a copper wire, a current-carrying capacity of a IS copper-sheathed aluminum alloy wire that has a same diameter is greater and a temperature rise thereof is lower; (2) when compared with a copper bar, a current-carrying capacity of a copper-sheathed aluminum alloy bar that has a same diameter is greater and a temperature rise thereof is lower; (3) when compared with a steel tube, a current-carrying capacity of a copper-sheathed aluminum alloy tube that has a same diameter and a same cross-sectional area is greater and a temperature rise thereof is sower; and (4) when compared with a copper stranded wire, a current-carrying capacity of a copper-stranded aluminum alloy wire that has a same diameter is greater, and a temperature rise thereof is lower, Compared with a copper conductor, an aluminum conductor, a copper-sheathed aluminum conductor, and a conductor with insulation between copper and aluminum, a conductor formed by using the method for using a copper and an aluminum alloy in cooperation has a higher current-carrying capacity and a lower temperature rise. The application of a metal oxide layer as an insulation protective layer achieves an energy-saving effect, with an improved current-carrying capacity, a low temperature rise and a reduced cost.
