Abstract
The utility model relates to a copper clad aluminium conductor bar which comprises a core body and a copper layer coated outside the core body. The core body is a magnesium aluminum alloy, and the copper layer is formed at the outer side of the core body by a squeezing and pressing method and is combined with the core body metallurgy. The cross sectional area of the copper layer accounts for 13-21% of that of the copper clad aluminium conductor bar. The copper clad aluminium conductor bar has the advantages that, 1, the tensile strength and the elongation rate are good, therefore, the product has wider adaptive application range; 2, the extensibility and the reliability are good, therefore, the copper clad aluminium conductor bar is easy for subsequent processing; 3, the conductive property is good, and the cost is low.
Description
Technical field
The utility model relates to the bimetallic busbar that uses in a kind of power equipment.
Background technology
Be used for that busbar in the distribution field is many to be made of pure copper material, but the fine copper busbar has density is big, quality heavy, production cost is high shortcoming.For overcoming above-mentioned shortcoming, also the someone proposes to adopt the copper cover aluminum busbar to substitute the fine copper busbar, and the copper cover aluminum busbar is to coat the layer of copper layer in the outside of fine aluminium plug, and its performance and price all are better than the fine copper busbar, have therefore obtained at present using widely.But because the core in the copper cover aluminum busbar generally adopts fine aluminium to make, so its tensile strength is lower, in use fracture easily.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, a kind of tensile strength and elongation copper cover aluminum busbar preferably to be provided.
For achieving the above object, the technical solution adopted in the utility model is: a kind of copper cover aluminum busbar, the copper layer that comprises core body and be coated on the described core body outside, described core body is a magnadure, described copper layer is molded over the outside of described core body and described copper layer and described core body metallurgical binding by extrusion.
The further technical scheme of the utility model is: the cross-sectional area of described copper layer accounts for 13 %～21% of the cross-sectional area of described copper cover aluminum busbar.
Preferably, the cross-sectional area of described copper layer account for described copper cover aluminum busbar cross-sectional area 15%.
Preferably, the cross section of described copper cover aluminum busbar is a rectangle.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, good mechanical performance: copper cover aluminum busbar of the present utility model tensile strength after testing is 273MPa, elongation 〉=13 %, greater than core body is the tensile strength and the elongation of the bimetallic busbar of fine aluminium, solved the copper clad aluminum wire defective of fracture easily, made the adaptable range of application of product wider;
2, good ductility and reliability: the utility model has preferable plasticity through after the Technology for Heating Processing, helps punching, shearing, bending machining;
3, with low cost: the utility model can reach busbar parameters standard, the copper layer cross section is long-pending to be compared with the fine copper busbar than the electric conductivity that is 15% copper cover aluminum busbar, it exchanges ampacity is 85% of fine copper busbar, and price is than cheap many of fine copper busbar.
Description of drawings
Accompanying drawing 1 is a sectional view of the present utility model;
Wherein: 1, core body; 2, copper layer.
Embodiment
Shown in accompanying drawing 1, a kind of copper cover aluminum busbar, the copper layer 2 that comprises core body 1 and be coated on described core body 1 outside, described core body 1 is a magnadure, described copper layer 2 is molded over the outside of described core body 1 and described copper layer 2 and described core body 1 metallurgical binding by extrusion.Wherein, the content that is used for making the magnadure magnesium of core body 1 is 1.0%～1.6%, and the content of Fe is smaller or equal to 0.12%, and the content of Si is smaller or equal to 0.08%, and the content of Cu is smaller or equal to 0.002%, and the content of Zn is smaller or equal to 0.008%, and all the other are aluminium content.
The cross-sectional area of described copper layer 2 accounts for 13 %～21% of the cross-sectional area of described copper cover aluminum busbar, preferably, the cross-sectional area of described copper layer 2 account for described copper cover aluminum busbar cross-sectional area 15%.The cross section of described copper cover aluminum busbar is a rectangle.
Copper covered steel ground connection of the present utility model row's price is than cheap many of fine copper ground connection row, and complete alternative fine copper or copper-clad fine aluminium busbar reach the purpose that reduces product cost.
The foregoing description only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection range of the present utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection range of the present utility model.
Claims (4)
1. copper cover aluminum busbar, the copper layer that comprises core body and be coated on the described core body outside, it is characterized in that: described core body is a magnadure, and described copper layer is molded over the outside of described core body and described copper layer and described core body metallurgical binding by extrusion.
