SUPERCONDUCTING MAGNET FOR EDDY CURRENT BRAKING OF HIGH-SPEED TRAIN

WIPO Patent Application WO/2020/020168

A1

Provided is a superconducting magnet for eddy current braking of a high-speed train. The superconducting magnet for eddy current braking of a high-speed train is fixed at the bottom of a bogie of the high-speed train by means of a connection mechanism, and forms an air gap with a top face of a guide rail below the bogie; after excitation, the superconducting magnet can produce an eddy current effect with the guide rail of the high-speed train and generate a braking force opposite to the direction of travel of the train, so as to achieve the braking of the high-speed train; the superconducting magnet is provided with a liquid level detection sensor for detecting a refrigerant liquid level position in real time; and the superconducting magnet is adaptable, by means of an elastic pull rod thereof, to the impact on the superconducting magnet brought about by the vibrations generated during the high-speed running of the train. The superconducting magnet for the eddy current braking of the high-speed train of the present invention has good adaptability in an environment where the train runs at high speeds.
