Abstract
The invention discloses a copper-aluminum composite electrical busbar and a production method thereof. The copper-aluminum composite electrical busbar comprises a busbar body; the busbar body is composed of an inner-layer aluminum bar and a pure copper cladding layer. The inner-layer aluminum bar is molded through pure aluminum cold extrusion. The pure copper cladding layer is molded through the following manners that: with the inner-layer aluminum bar is adopted as a base body, pure copper is uniformly extruded through horizontal heat extrusion so as to cover the periphery of the inner-layer aluminum bar; and cooling, cold drawing and sizing are carried out. The width and thickness of the inner-layer aluminum bar are respectively 1/3 of the width and thickness of the busbar body. Compared with an existing pure copper busbar, the copper-aluminum composite electrical busbar has the following advantages that: conductivity is not affected; the weight of the busbar is reduced; and raw material cost can be reduced.
Description
Technical field
The present invention relates to electrician's bus production technical field, particularly a kind of Copper-Aluminum compound electrician's bus bar and production method thereof.
Background technology
Electrician's bus, also known as bus bar, it is a kind of conducting heavy current product, is widely used in the electric power facilities such as high and low voltage electrical equipment contact, equipment for power transmission and distribution, power transmission busbar, be more particularly suited for the super-large current electrolysis for production engineering such as metal smelt, electrification plating, chemical industry Caustic soda.
Copper is precious metal, and proportion is bigger. In recent years, owing to worldwide copper resource is day by day in short supply, cathode copper forward price continues to raise up, domestic be primary raw material with copper industry be subject to extreme shock, whole industry is badly in need of one and both can guarantee that product serviceability, and the new material that can reduce again production cost replaces fine copper.
According to electric current " Kelvin effect ", when more than 5MHz high frequency, its conductivity depends primarily on outer layer metal, so currently used fine copper row, in high frequency transmission of electricity, do not occupy too many advantage, but consume substantial amounts of copper resource in vain, increase the cost of manufacturer.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of Copper-Aluminum compound electrician's bus bar and production method thereof, to reach not only to reduce the cost of raw material but also do not affect the purpose of conductivity.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of Copper-Aluminum compound electrician's bus bar and production method thereof, including bus bar body, described bus bar body is made up of unlined aluminium row and fine copper outer covering layer, described unlined aluminium is arranged by fine aluminium through cold extrusion shaped, described fine copper outer covering layer is to arrange as matrix with described unlined aluminium, by horizontal type hot extrusion fine copper extruded equably and cover that described unlined aluminium is exclusive to be enclosed, be then passed through cooling, cold-drawn, scale and molding.
As the further optimization of the present invention, a kind of Copper-Aluminum compound electrician's bus bar and production method thereof, it is characterised in that described unlined aluminium row's width and thickness account for 1/3rd of described bus bar body width and thickness respectively.
Compared with existing fine copper busbar, the invention has the beneficial effects as follows:
A kind of Copper-Aluminum compound electrician's bus bar, neither affects conductivity, can alleviate again bus bar weight and reduce the cost of raw material.
Accompanying drawing explanation
Below the content expressed by this specification accompanying drawing 1 and the labelling in figure are briefly described:
Accompanying drawing 1 is one Copper-Aluminum compound electrician's bus bar section structure schematic diagram of the present invention.
In accompanying drawing 1,1, bus bar body, 2, unlined aluminium row, 3, fine copper outer covering layer.
Detailed description of the invention
Below in conjunction with accompanying drawing, principles of the invention and feature being described, example is served only for explaining the present invention, is not intended to limit the scope of the present invention.
A kind of Copper-Aluminum compound electrician's bus bar and production method thereof, including bus bar body 1, described bus bar body 1 is made up of unlined aluminium row 2 and fine copper outer covering layer 3, described unlined aluminium arranges 2 by fine aluminium through cold extrusion shaped, described fine copper outer covering layer 3 is to arrange as matrix with described unlined aluminium, by horizontal type hot extrusion fine copper extruded equably and cover that described unlined aluminium is exclusive to be enclosed, be then passed through cooling, cold-drawn, scale and molding.
As the further optimization of the present invention, a kind of Copper-Aluminum compound electrician's bus bar and production method thereof, it is characterised in that described unlined aluminium arranges 2 width D and thickness M accounts for 1/3rd of described bus bar body 1 width L and thickness H respectively.
Above the preferably enforcement of the present invention is illustrated; certainly; the present invention can also adopt form different from the embodiment described above; equivalent conversion that those of ordinary skill in the art make under the premise without prejudice to spirit of the present invention or change accordingly, all should belong in protection scope of the present invention.
Claims (2)
