The invention provides a testing device for the adhesion resistance of a carbon sliding plate. The testing device comprises a base, two groups of power supply structures and a testing component, wherein the power supply structures are arranged on the base and are respectively in contact with a carbon sliding plate, a testing region for accommodating the carbon sliding plate is formed between two groups of the power supply structures, the power supply structures can press the carbon sliding plate in the testing region so as to electrify the carbon sliding plate, and the carbon sliding plate isin surface contact with the power supply structures when the carbon sliding plate is pressed by the power supply structures; and the testing component acts on a first detection point and a second detection point of the carbon sliding plate and is used for acquiring a current value or a resistance value of the carbon sliding plate. The carbon sliding plate is in surface contact with the power supply structures, so that the voltage supplied by the power supply circuits to the carbon sliding plate is relatively stable, and the measurement precision is relatively high.
Description
technical field [0001] The invention relates to the technical field of performance testing of carbon skateboards, in particular to a testing device for bonding resistance of carbon skateboards. Background technique [0002] Carbon skateboards are important components of electric locomotives, EMUs, light rails, and subways. Carbon slides are permanently attached to brackets by bonding, installed on the head of the pantograph, and directly contacted with catenary wires. A category of sliding contact material, the slide receives current from the catenary wire to supply the locomotive with electricity. Therefore, the pantograph slide plate and the catenary wire constitute a pair of special friction pairs with mechanical and electrical coupling, and its working conditions have the following characteristics: periodic random load changes; strong current passing through contact; high-speed sliding; complex and diverse environmental conditions Change. The main failure mode of the s...
