Abstract

The invention belongs to the technical field of superconducting magnet excitation systems, and discloses a high-temperature superconducting flux pump system. The system comprises a flux pump body, a superconducting load and a stator set. A double-pancake coil assembly at least comprises a double-pancake coil; the stator set at least comprises a stator; the flux pump body is provided with an air gap for containing the stator set; and the superconducting load and the stator set are connected to form a closed loop. Under the condition that the magnet structure and the winding cost are not changed, the structure is correspondingly simplified, the problem that the charging speed of the magnet is low is solved, and meanwhile the power supply cost is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of superconducting magnet excitation systems, and in particular relates to a high-temperature superconducting magnetic flux pump system. Background technique [0002] Superconducting magnets are an extremely important part of superconducting power applications. Compared with traditional permanent magnets and ordinary electromagnets, they are light in weight and small in size, can generate stronger magnetic fields, and have extremely low losses. With their advantages, superconducting magnets are used in many fields of medical treatment, energy and transportation. [0003] The difficulty in developing current superconducting magnets is that high-temperature superconducting coils cannot be operated in continuous current mode. Since the current loss caused by flux creep and welding resistance has not been completely resolved, the current attenuation of the high-temperature superconducting magnetic closed loop c...
