Abstract
The utility model discloses an aluminum bus bar with copper coated joint used for power transmission line. A copper composite layer is coated on the aluminum bus bar as surface anti-oxidation conductive body transition layer of the aluminum bus bar, having thickness not less then 0.1 mm. The copper is coated in two ways such as coating the copper composite layer at terminal of the aluminum bus bar in upper and lower layers, and coating the copper composite layer around the terminal of the aluminum bus bar. Applying the utility model, anti-oxidation effect of copper bus bar joint is achieved, anti-oxidation problem of aluminum bus bar joint is solved, and cost is greatly reduced comparing with copper bus bar and copper-aluminum composite bus bar.
Description
Technical field
The utility model be a kind of be used for electric line cover the copper sleeve aluminum bus bank, belong to the technical field that the power transmission and distribution conductor material is made.
Background technology
The existing conductor busbar that is used for electric line, material are generally novel conductor material copper or aluminium matter and present instead of copper bus---copper aluminium composite bus row.Because the copper shortage of resources causes the copper valency to rise suddenly and sharply, equipment for power transmission and distribution and circuit adopt copper busbar as conductor material, and its material cost is more and more higher, have caused great financial burden for the customer investment cost.Aluminium row also has excellent conducting performance, in light weight, price is low, but in transmission line, use, because very easily oxidation and form insulating barrier of aluminium surface, cause the joint contact resistance to increase heating, heating has aggravated the oxidation rate on aluminium surface again, has formed vicious circle, finally causes transmission line to burn outage and the accident of producing because of the contact-making surface of joint.Though the aluminium busbar joint adopts copper facing to add the problem that zinc-plated or silver-plated method can solve the joint oxidation, but at present that is that all right is ripe in the technology of aluminium copper coating, quality is still unstable, and because of whole coating is thin, adhesive force is bad, it is crisp easily to produce cyanogen in the electroplating process, coating easily peels off, anti-oxidant nargin does not reach requirement, its useful life is not long, and there is serious hidden danger in security reliability.Copper aluminium is compound, aluminium covers copper, copper cover aluminum as an alternative the novel conductive body material of copper, aluminium come out one after another, alleviated the contradiction that copper bus-bar shortage of resources and supply and demand increase, all there is the drawback of these several aspects in all these complex copper aluminum conductor materials:
1, copper aluminum composite material is because the conductance of copper, aluminium is different, there are the difference of sectional area thickness again in copper and aluminium at length direction, so it is inaccurate what objectively caused ampacity and sectional area to calculate, properties of product and security reliability are can not determine in the run-of-the-mill check, make the user produce worried psychology.
2, in use, because the heat of electric current, resistance generation, the compound row of copper aluminium can cause the compound row of copper aluminium crooked to one side because the stress that length direction thickness difference is produced does not wait, and serious meeting causes potential safety hazard.
3, in a single day the copper aluminium composite bus is used in a large number, and material is difficult for separated recovery, though because the aluminium fusing point is low, when copper arrived fusing point at aluminium, soon by the dissolving of the aluminum solutions of high temperature, the copper resource can not be repeated to utilize, and industry does not form recycling economy.
Summary of the invention
Technical problem: goal of the invention of the present utility model provides a kind of copper surface oxidation-resistant performance that has, and electric conductivity is superior, low-cost, safe and reliable covers the copper sleeve aluminum bus bank.
Technical scheme: the copper sleeve aluminum bus bank that covers of the present utility model has been laminated with copper composite bed as aluminum bus bank surface oxidation-resistant electric conductor transition zone in the end of aluminum bus bank, the thickness of copper composite bed is no less than 0.1mm, again at copper composite bed electroplating surfaces with tin or silver-plated, to guarantee to cover copper sleeve security reliability in use as corrosion-resistant treatments.
Its mode of covering copper has following two kinds:
The copper composite bed that is laminated with in the end of aluminum bus bank is for two-layer up and down.
The copper composite bed that is laminated with in the end of aluminum bus bank is for cover copper aluminium row in one week of end.
Beneficial effect: the copper sleeve aluminium bus array that covers of the present utility model has reached the oxidation resistant effect of copper bus-bar joint, has solved the oxidation resistant problem of aluminium bus array joint, compares with copper busbar row and copper aluminium composite bus row, and cost is reduced significantly.Covering copper sleeve aluminum bus bank ampacity cross section calculates by the aluminum bus bank conductance, because aluminium row sectional area is more than 1.6 times of copper bar, aluminum bus bank thermal capacity is arranged greater than copper busbar, and under the situation of same current class and environment, the temperature rise of covering the copper sleeve aluminum bus bank is lower than copper busbar row.Cover the copper sleeve aluminium bus array and do not exist Copper Aluminium Composite Main Row to cause the cross section to calculate inaccurate problem because of covering copper, and the problem of the busbar bending that causes of stress reason.It is very little for copper bauxite resource separation recovery aspect influence to cover the copper sleeve aluminum bus bank, is beneficial to the development of recycling economy.

Embodiment
The copper sleeve aluminum bus bank that covers of the present utility model is to be covered with to be no less than the thick copper composite bed of 0.1mm as aluminium row surface oxidation-resistant electric conductor transition joint on aluminium row and aluminium row's link body, cover the copper layer and can determine that it covers the area size of copper according to the needs of electric conductor contact-making surface, joint can all cover copper around aluminium row, or do not wait the problem of the stress intensity that produces in conjunction with the coefficient of expansion of copper aluminium material material, reserve cut in aluminium row Width both sides and be used to eliminate stress, the copper composite bed 1 that promptly is laminated with in the end of aluminum bus bank 2 is for two-layer up and down.In order to guarantee that the joint that covers the copper sleeve aluminium bus array obtains better anti-oxidant electric conductivity, can carry out zinc-plated, silver-plated anti-oxidant surface treatment on the copper sleeve covering, reach the serviceability of copper bus-bar joint.
