摘要
A superconducting eddy current brake for a high-speed train, comprising a pair of superconducting magnet units (1) forming alternating N and S poles, and a low-temperature refrigerating unit (6); the superconducting magnet units (1) are fixedly mounted on the bottom of a bogie (15) of the high-speed train and form an air gap with the top face of a guide rail (16) below the bogie; the low-temperature refrigerating unit (6) is mounted on the bogie (15) of the high-speed train; each superconducting magnet unit (1) comprises a superconducting container, the superconducting container comprising a coil box (12), a cold screen (13), and a dewar (14) nested in sequence from inside to outside, the inside of the coil box being filled with liquid helium, a superconducting coil (11) immersed in the liquid helium being arranged inside the coil box, inside the cold screen (13) being a high vacuum environment, and liquid nitrogen circulation pipelines being densely distributed on the outer wall of the cold screen. The present brake satisfies a braking function during high-speed operation, and also caters to the requirements for lightening high-speed trains and saving energy and reducing emissions.
