Abstract

The invention relates to a conduction cooling technology-based refrigerating system for a superconducting motor. The conduction cooling technology-based refrigerating system comprises a compressor, a refrigerator cold head, a sealing device, a vacuum cover, a magnet framework, a cold conduction band and an anti-radiation screen, wherein the anti-radiation screen is fixedly arranged on the inner wall of the vacuum cover through a support structure; the compressor is connected with the refrigerator cold head through the sealing device; the refrigerator cold head passes through the vacuum cover and the anti-radiation screen in sequence, and is fixedly arranged on the vacuum cover; the refrigerator cold head rotates synchronously with the vacuum cover and the anti-radiation screen; the magnet framework for installing a superconducting magnet is arranged in the anti-radiation screen; two ends of the magnet framework pass through the anti-radiation screen through torque tubes respectively, and are connected to two ends of the vacuum cover; the cold conduction band is connected to the inner wall of the magnet framework; and the cold conduction band is connected with the refrigerator cold head positioned in the anti-radiation screen. A magnet is cooled in a conduction cooling way by adopting the efficient cold conduction band, and a cooling medium used in the conventional cooling scheme is eliminated, so that the using flexibility of the system is enhanced, the reliability is higher, and the failure rate of the system is lowered effectively.

Description

technical field [0001] The invention relates to a refrigeration technology of a superconducting motor, in particular to a refrigeration system of a superconducting motor based on conduction cooling. Background technique [0002] As an emerging technology, superconducting technology has gradually shown irreplaceable advantages in power applications. The fan manufactured by superconducting technology has a rotor wound by high-temperature superconducting (HTS) wire, and its current-carrying density can be increased by about 150 times compared with conventional copper wire, making superconducting motors have extremely high energy density. On the one hand, the volume of the motor is greatly reduced. At the same time, because the superconducting coil can generate a very strong magnetic field, the iron core in the motor can be omitted, and the weight of the motor is also reduced a lot. According to the estimation of American Superconducting Corporation, the weight of 10MW supercon...
