Problems solved by technology

However, for the superconducting magnet system, the protection by simply turning off the power supply cannot quickly reduce the high current flowing through the high-temperature superconducting wire, so the quenching of the high-temperature superconducting wire cannot be truly realized. Protect

Abstract

The invention relates to a quench protection method for a superconducting magnet system and a high-temperature superconducting wire, wherein the superconducting magnet system includes: a superconducting coil, a high-temperature superconducting wire, a heater, a heater trigger, and a high-temperature superconducting wire detection unit. The high-temperature superconducting wire detection unit is used to detect the working state of the high-temperature superconducting wire, and when the detection signal from the high-temperature superconducting wire is greater than a preset value, the high-temperature superconducting wire detection unit outputs a control signal to the A heater trigger is used to trigger the heater to work to quench the superconducting coil, and the preset value corresponds to the quench point or the quench critical point of the high-temperature superconducting wire.

Description

technical field [0001] The invention relates to a superconducting magnet system, in particular to a superconducting magnet system with quench protection for high-temperature superconducting leads and a quench protection method thereof. Background technique [0002] With the vigorous development of superconducting technology and superconducting materials, superconducting magnets have broad application prospects. Due to the advantages of small size, high current density, low energy consumption, and high magnetic field strength, superconducting magnets are increasingly used in basic scientific research, medical and health, transportation, and national defense industries. For example, in a magnetic resonance imaging (Magnetic Resonance Imaging, MRI) system, a superconducting magnet is used to generate a uniform magnetic field. [0003] Superconducting magnets are usually operated at a higher current (for example, about 200A-800A) to provide energy to obtain a uniform magnetic f...
