AI Technical Summary

Problems solved by technology

[0005] However, the traditional busway shell is formed by die-casting alloy steel, and the tolerance accuracy error of die-casting parts is relatively large, and the processing is time-consuming and laborious.
[0006] Aiming at the disadvantages of traditional alloy steel, such as low hardness and no corrosion resistance, Publication No. (206611136U) discloses a bus duct whose shell is made of copper-clad aluminum alloy, although compared with alloy steel, it has improved performance protection
However, copper-clad aluminum alloys still have defects such as strength, wear resistance, and corrosion resistance.

Abstract

The invention relates to an air busbar and a preparation method thereof and belongs to the field of metal materials. A metal housing of the busbar is made with aluminum-magnesium alloy, specially, Sipowder, Mg powder, hydrides, Ni powder, Sn powder and Al powder. The hydrides are added into the aluminum alloy; the added elements are fused in the alloy; the process of not external guidance but character itself is provided; purity of a material can be fully guaranteed, invasion of impurities is avoided; the metal shell is made via the steps of burdening, forming, and sintering and the like; thetechnique is simple and suitable for large-scale production; ceramic membrane is formed on the surface of the alloy, providing very high hardness and corrosion resistance and fully extending the service life.

Description

technical field [0001] The invention relates to an air type bus duct and a preparation method thereof, belonging to the field of metal materials. Background technique [0002] The emergence of modern engineering facilities and equipment has led to a sharp increase in electricity consumption in various industries, especially in many high-rise buildings and large workshops. Traditional cables cannot meet the requirements in large current transmission systems, and the parallel use of multiple cables is also inconvenient for construction. Case. As a new type of power distribution conductor, bus duct has emerged at the historic moment, which not only has high current transmission capacity, but also is easy to construct. Compared with traditional cables, it fully demonstrates its superiority in the transmission of large currents, while the contact resistance and temperature rise of the connection at the end of the bus duct and the insertion of the branch outlet are lower, and it ...
