摘要： A method of operating a superconducting switch system to protect against quenching in a superconducting magnet circuit is provided. The system comprises a magnet circuit, a main superconducting switch and an auxiliary superconducting switch connected in parallel thereto by low resistance connecting parts. In an initial magnet energisation procedure, after establishing superconducting flow in the circuit, the main and auxiliary switches are closed to cause current to persist in the circuit without further power input. If the main switch quenches, the current will transfer to the auxiliary switch through the resistive connecting parts. Upon restoring the main switch to the superconducting state, the voltage drop through the resistive connecting parts will drive the current back through the main switch. A preconditioning procedure is carried out as part of the magnet energisation procedure to ensure that opening the main switch will establish superconducting current through the auxiliary switch.

摘要翻译：提供了一种操作超导开关系统以防止在超导磁体电路中淬火的方法。该系统包括磁电路，主超导开关和通过低电阻连接部分与其并联的辅助超导开关。在初始磁体激励过程中，在电路中建立超导流动之后，主开关和辅助开关闭合，以使电流在电路中保持不变，而不需要进一步的电力输入。如果主开关熄灭，电流将通过电阻连接部件传输到辅助开关。在将主开关恢复到超导状态时，通过电阻连接部件的电压降将驱动电流回到主开关。作为磁体激励程序的一部分执行预处理过程，以确保打开主开关将建立通过辅助开关的超导电流。

摘要： A superconducting switch system is provided in a superconducting magnet circuit (40) comprising a number of magnet coils (41) serially connected together by superconducting joints. The switch system comprises a main superconducting switch 1, which carries the magnet operating current during normal operation of the circuit, and an auxiliary superconducting switch 2 connected in parallel with the main switch 1 and connected to the circuit by low resistance connecting parts 2 and 4 (45), preferably constituted by solder joints, rather than superconducting connections. In operation, once appropriate current has been supplied to the circuit with the main and auxiliary switches 1, 2 in the open position, the main and auxiliary switches 1, 2 are closed in order to cause the current to persist in the circuit 40 without further power input. If the main switch 1 quenches, the current will transfer to the auxiliary switch 2 through the resistive connecting parts 3 and 4. Subsequently, after the main switch 1 has been re-cooled and has recovered to the superconducting state, the voltage drop through the resistive connecting parts 3 and 4 will drive the current back to the main switch 1. In this manner the main switch is protected by the auxiliary switch from external or internal events or interference.
