Description
Technical field:
The present invention relates generally to transition electric connection method between a kind of copper aluminium, relates in particular to a kind of copper-aluminum transition electric connection method that adopts copper aluminium Composition spacer as adaptor.
Background technology:
Demand for copper-aluminium transition connects is present in the industry-by-industry field, as: industry fields such as electrolytic aluminium, cathode copper, chlor-alkali, oil, chemical industry, electric power and transmission of electricity, power transformation, power equipment.Be example now with electric power and power equipment industry:
In traditional electric power and the power equipment industry, it mainly is to realize by copper to aluminum adapter bar, copper-aluminium transition wire clip and copper al wiring terminal that copper-aluminium transition connects, being connected of copper to aluminum adapter bar, copper-aluminium transition wire clip and copper al wiring terminal copper and aluminium itself generally adopts flash welding, friction welding (FW), soldering connection method to realize, usually, the composition surface is difficult to realize metallurgical binding completely, the percent defective height, bond strength is low, copper material consumption is big, occur phenomenon of rupture easily, and can cause equipment and power transmission and transformation line failure rate height.
Existing copper-aluminum transition electric connection method is: adopt explosive welding to obtain in conjunction with rolling mill practice between copper to aluminum adapter bar and the copper-aluminium transition wire clip copper aluminium sheet, because the interface of explosive welding belongs to metallurgical binding between atom, thereby its interface resistance is little of ignoring, this not only can save energy consumption and can also increase the service life, and has saved copper material.Its drawback is:
One: no matter be local or all adopt explosive welding and the rolling copper that covers on the aluminium sheet,, just need carry out further copper-aluminium transition and process to the moulding wire clamp as long as make copper-aluminium transition wire clip realize that fully copper-aluminium transition connects.The processing method of improving its fade function has " scarfweld copper ring ", and " scarfweld copper ring " operation can make the consumption of copper increase, the multiplication of following process workload, the expense that is produced the almost cost with saving copper (relative traditional copper to aluminum adapter bar, copper-aluminium transition wire clip and copper al wiring terminal) is suitable substantially, is unfavorable for large-scale industrialization production.
Two: the copper ring in " scarfweld copper ring " formula copper-aluminium transition wire clip " scarfweld " is in advance finished, as runs into two copper double-screw bolt spacings of leading-out terminal and " scarfweld copper ring " pitch of holes of formula copper-aluminium transition wire clip not simultaneously, and the staff can't finish installation.
Three: no matter be local or all carry out explosive welding and the rolling copper that covers on the aluminium sheet, it obtains the cost of metallic explosive soldering copper aluminum composite plate, be worth almost equal with the copper material of being saved, wherein in confined explosion's combination process of Cai Yonging, though the use amount of copper has reduced, but because the explosion cladding process complexity improves, cause productivity ratio to descend, cause the unit processing cost to rise.
As seen, still there are problems such as the copper consumption is big, manufacturing cost is high, industrialization degree is low, on-the-spot use inconvenience in novel copper to aluminum adapter bar, copper-aluminium transition wire clip and copper al wiring terminal.
Summary of the invention:
Purpose of the present invention is exactly in order to remedy the defective of prior art, and the copper aluminium Composition spacer that provide that a kind of employing conducts electricity very well, the copper material use amount is few, low cost of manufacture, fitting operation are simple, forever can not come off is as the copper-aluminum transition electric connection method of adaptor.
The present invention is achieved by the following technical solutions:
The present invention is a kind of copper-aluminum transition electric connection method, it is characterized in that: in electrical power wiring, in the occasion that adopts copper or aluminium bolt that copper, the transition of al wiring end are connected, adopt copper aluminium Composition spacer as adaptor, copper aluminium Composition spacer is sandwiched between copper, the al wiring end, makes that the contact-making surface of copper aluminium Composition spacer and copper, al wiring end is with a kind of metal material; When the nut of bolt and its press down the terminals material of applying when consistent, directly adopt bolt that copper, al wiring end are fixed; Press down the terminals material of applying with it when inconsistent as the nut of bolt, between the nut of bolt and its terminals that press down applying, increase copper aluminium Composition spacer, make copper aluminium Composition spacer and contact-making surfaces bolt nut, terminals for a kind of metal material; Described copper aluminium Composition spacer is made up of copper sheet that is welded as a whole and aluminium flake.
Described copper-aluminum transition electric connection method, the mesopore that it is characterized in that described copper aluminium Composition spacer have the edge that turns up towards copper sheet side or aluminium flake side, when selecting copper aluminium Composition spacer for use, guarantee that edge inwall and bolt are with a kind of metal material.
Described copper-aluminum transition electric connection method is characterized in that described copper aluminium Composition spacer is a flat pad.
Copper aluminium Composition spacer adopts is that metallic explosive welding or blast add rolling copper-aluminum composite board and be made, and does not need special-purpose copper to aluminum adapter bar, copper-aluminium transition wire clip and copper al wiring terminal.Copper aluminium Composition spacer is through a drawing, no any weld seam and crackle between two pads.The copper-aluminum composite board gross thickness is 2mm, and wherein copper, aluminium thickness respectively are 1mm.Realized the breakthrough of copper zero use amount in copper to aluminum adapter bar, copper-aluminium transition wire clip and the copper al wiring terminal in the past.Copper aluminium Composition spacer can realize that the transition between copper aluminium connects, but also the continuous conversion that can carry out between copper aluminium connects.
The side edge in the copper aluminium Composition spacer and the resistance on aluminium flake side edge are respectively copper and the resistance value of aluminium own, and the resistance of copper aluminium junction is metallic explosive soldering copper aluminum composite plate resistance value.In the whole manufacturing process of copper aluminium Composition spacer, guarantee the integraty of pad, except the resistance of explosive welding copper-aluminum composite board material itself, in the post-production forming process, avoided the way of any increase resistance.
The copper layer can be realized the aluminum bronze transition when last; The copper layer can be realized copper-aluminium transition in following time.
When being used, two copper aluminium Composition spacers will form an I-shaped insulating space, for example: leading-out terminal is under the situation of copper wire post, as long as aluminium connecting plate end tapping to be connected is loaded onto copper aluminium Composition spacer up and down respectively, tighten the fixed-link screw and can finish the transition connection.
Advantage of the present invention is:
Copper aluminium Composition spacer structure among the present invention is tight; can obtain more superior switching performance; reduced the use amount of copper material; solution and manufacturing process uniqueness, easy, with low cost; not only can carry out large-scale production, also guarantee the on-the-spot versatility of installing and using simultaneously, simple to operation; cost of manufacture is low, and spreading speed is fast.
