Abstract

The invention discloses a carbon contact strip of a pantograph and a manufacturing method thereof. The carbon contact strip is prepared from following raw materials, by weight, 28-43 parts of petroleum coke powder, 25-28 parts of asphalt coke powder, 10-12 parts of sprayed carbon black, 2-5 parts of sulfur, 3-5 parts of boron nitride, 5-8 parts of carbon fiber, 4-6 parts of natural graphite, 5-7 parts of artificial graphite, 1-3 parts of calcium chloride powder and 30-35 parts of modified asphalt. The carbon contact strip is high in mechanical strength, is good in self-lubricating performance and electric arc resistance and is wear-resistant. The carbon contact strip can be not only used in various locomotives in railway main lines with speed per hour being 120-250 km / h, but also used in motor train units and high-speed trains with speed per hour being higher than 250 km / h. The carbon contact strip is free of limit of environment and climate conditions.

Description

technical field

[0001] The invention belongs to the technical field of electric locomotives, and in particular relates to a novel high-speed traction locomotive pantograph carbon slide plate and a manufacturing method thereof. Background technique

[0002] The high-speed train obtains electric energy from the road network conductor through the pantograph slide plate, and drives the traction motor to drive the train to run. Reliable contact between the pantograph slide and the road network conductor is an important condition to ensure high-speed current collection. The sliding plate on the pantograph head is in contact with the wires of the road network, slides relative to each other, takes the current from the wires of the road network, and transmits it to the electric locomotive. This process is called receiving current. During the current receiving process, the road network wires and the pantograph slide are closely related mechanically and electrically. As long as one of...
