Copper-aluminum composite conductive rail and manufacturing method thereof

Abstract

The invention discloses a copper-aluminum composite conductor rail and a manufacturing method thereof. The copper-aluminum composite conductor rail comprises an aluminum rail and a copper conductive bar connected to the aluminum rail, wherein the copper conductive bar is provided with a conductive contact surface used for being in contact with a current collector of a locomotive; the conductive contact surface is a plane; two or more than two copper-aluminum composite conductive plates are further arranged between the aluminum rail and the copper conductive bar; each copper-aluminum composite conductive plate comprises an aluminum plate and a copper plate connected integrally; each aluminum plate is connected with the aluminum rail; each copper plate is connected with the copper conductive bar. The copper-aluminum composite conductor rail has the advantages of simple structure, likeliness in manufacturing, low manufacturing cost, high electrical conductivity, non-likeliness in heating, high safety, high reliability and the like. The manufacturing method comprises the following steps: preparing the aluminum rail, the copper conductive bar and the copper-aluminum composite conductive plates; performing press-fitting molding; additionally arranging a copper fastening bolt. The manufacturing method has the advantages of being convenient to operate, beneficial for processed production, high in production efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of rail transit equipment, in particular to a copper-aluminum composite conductive rail and a manufacturing method thereof. Background technique [0002] With the development of modern rail transit vehicle technology, new requirements are put forward for the power supply and current receiving equipment of electric rail vehicles, especially the power supply and current receiving devices of the newly emerging energy storage urban rail vehicle charging stations, as well as electric locomotives and urban rail vehicles. The power supply and current receiving equipment for static debugging of rail vehicles are required to have similar characteristics: they can withstand large currents for a long time without overheating, the cost should not be high, and they require certain horizontal and vertical bending resistance (such as mobile contactors for locomotive debugging) network requires it to have). [0003] At pre...
