本文介绍了将安装在日本中市的托卡马克 JT-60SA 卫星的超导环形场 (TF) 和极向场 (PF) 磁体的失超保护电路 (QPC) 的详细设计 [1]。 TF QPC 的标称中断电流和最大重新施加电压为 25.7 kA 和 2.8 kV，PF QPC 的标称电流为 20 kA 和 5 kV。 QPC 设计中提出的创新解决方案基于混合断路器 (CB)，该混合断路器由用于传导连续电流的机械旁路开关与用于中断电流的静态 CB 并联组成。提出并讨论了最终设计的主要选择，以确认或更新并完成在概念设计层面进行的研究。
This paper describes the detailed design of the Quench Protection Circuits (QPC) for the superconducting Toroidal Field (TF) and Poloidal Field (PF) magnets of the Satellite Tokamak JT-60SA, which will be installed in Naka, Japan [1]. The nominal currents to be interrupted and the maximum reapplied voltages are 25.7 kA and 2.8 kV for the TF QPCs and 20 kA and 5 kV for PF QPCs. The innovative solution proposed in the QPC design is based on a Hybrid Circuit Breaker (CB) composed of a mechanical Bypass Switch for conducting the continuous current, in parallel to a static CB for current interruption. The main choices of the final design are presented and discussed, either to confirm or to update and complete the study performed at the conceptual design level.
