Summary: | To provide a highly reliable superconducting magnet device in which the quench of a PCS can be suppressed, and an operation method of the superconducting magnet device.SOLUTION: A superconducting magnet device 100 includes: a superconducting coil 1; an excitation power supply 4 introducing current to the superconducting coil 1; a permanent current switch 2 connected in parallel with the superconducting coil 1 and the excitation power supply 4; and a heater 3 heating the permanent current switch 2. The permanent current switch 2 includes a plurality of winding bodies 20, each of which has self-inductance, and which is connected in series. The plurality of winding bodies 20 is arranged so that the mutual inductance between the winding bodies 20 has a negative value.SELECTED DRAWING: Figure 1
【課題】PCSのクエンチを抑制し、信頼性の高い超電導マグネット装置、および、超電導マグネット装置の運転方法を提供する。【解決手段】超電導マグネット装置100は、超電導コイル1と、超電導コイル1に対して電流を導入する励磁電源4と、超電導コイル1および励磁電源4に対して並列に接続された永久電流スイッチ2と、永久電流スイッチ2を加熱するヒーター3と、を具備する。永久電流スイッチ2は、各々が自己インダクタンスを有し直列に接続された複数個の巻線体20を有する。複数個の巻線体20は、複数個の巻線体20間の相互インダクタンスが負の値を有するように配置される。【選択図】図1 |
