Surface treatment process for aluminum base material conductor bus way

Abstract

The invention relates to a surface treatment process for an aluminum base material conductor bus way. The surface treatment process includes the steps of primary workpiece surface treatment, molecular osmotic treatment, plating and secondary workpiece surface treatment. By means of the surface treatment process for the aluminum base material conductor bus way, the surface oxidation resistance of an aluminum material is achieved, the surface conductivity is improved, and the contact resistance is lowered. The novel aluminum alloy bus way serves as a conductor, and on the premise of guaranteeing safe power supply, the cost of the bus way is greatly reduced. Compared with a copper conductor bus way with the same current-carrying capacity, the cost of the aluminum material bus way is only 30-35% that of the copper conductor product, so that the aluminum base material conductor bus way is economical.

Description

technical field [0001] The invention relates to a surface treatment process, in particular to a surface treatment process for an aluminum substrate conductor bus groove. Background technique [0002] Busway is a new circuit method called "Bus-Way-System" developed by the United States. It uses copper or aluminum as a conductor, supports it with non-olefinic insulation, and then installs it in a metal groove. Conductors, modern high-rise buildings and large workshops require huge power, and in the face of the huge loads requiring hundreds of thousands of amperes of strong current, it is necessary to choose safe and reliable conduction equipment. The busway system is a power distribution device for efficient current transmission, especially to meet the needs of economical and reasonable wiring of increasingly taller buildings and large-scale factories. [0003] Of course, in order to achieve a good conductive effect, copper is the preferred material of the bus duct, but in or...

AI Technical Summary

Problems solved by technology

[0003] Of course, in order to achieve a good conductive effect, copper is the preferred material of the bus duct, but in order to save costs, many bus ducts are now also made of aluminum, and the conductivity of aluminum as a power system conductor is about 77% of that of copper conductors with the same cross section. %, because of its low price and small specific gravity, to achieve the same current carrying capacity, the cost of using aluminum is less than 20% of the cost of copper

However, because the surface of aluminum is easy to oxidize, the oxidized aluminum becomes an insulator, resulting in poor electrical conductivity of copper-aluminum and aluminum-aluminum contact and heating, causing power accidents. None of the existing aluminum bus ducts on the market can overcome the defect of easy oxidation. Even if this defect is overcome, it will cost a lot of money, which violates the original intention of making bus ducts from aluminum
