Problems solved by technology

[0004] The metal-impregnated carbon slide is to fill a large number of pores in the carbon strip substrate with metal to form a practical condensate. In the past, the pores on the carbon strip were naturally formed during the production process of the carbon strip. These pores were scattered in the form of points. In the carbon strip, the impregnated metal is also scattered in the carbon strip in dots, which cannot achieve the best effect of reducing the resistivity of the carbon strip

Abstract

The invention provides a method for making a carbon-fiber-reinforced pantograph carbon slide plate carbon strip, and the method comprises the following steps: uniformly mixing a pantograph carbon slide plate carbon strip raw material and a pore forming agent to obtain a mixture; pressing the mixture to obtain a carbon slide plate carbon strip initial blank containing the pore forming agent; calcining the carbon slide plate carbon strip initial blank to burn out the pore forming agent in the carbon slide plate carbon strip initial blank to form pores in uniform distribution in the carbon slide plate carbon strip so as to obtain a carbon slide plate carbon strip with a pore structure; and performing metal impregnation treatment on the carbon slide plate carbon strip with the pore structure to obtain the carbon slide carbon strip having a uniformly-distributed metal. The prepared carbon strip has the advantages of low resistivity, strong electric conductivity, high strength and long service life by addition of the pore-forming agent to control the number and shape of the pores in the carbon strip so as to make the impregnated metal in a uniformly-distributed net structure.

Description

technical field [0001] The invention relates to a preparation method of a carbon fiber-reinforced pantograph carbon strip, in particular to a preparation method of a carbon fiber-reinforced pantograph carbon strip with evenly distributed metal, belonging to the technical field of electric locomotives. Background technique [0002] An electric locomotive is a locomotive that obtains electric energy from the catenary and is driven by a traction motor. With the development of electrified railways, electric locomotives have also developed rapidly, from DC motor locomotives to AC drive electric locomotives. In 1979, the first high-power AC drive locomotive was born in Germany, ushering in a new era of development of electric locomotives. In order to obtain large capacity and high speed, the power of electric locomotives is increasing. In 1961, the Baoji-Fengzhou line, China's first electrified line, was completed. The power of electric locomotives has grown from 4740kw to 6400k...
