When quench happens, the energy stored in the superconducting magnet is required to be transferred and consumed to fast discharge resistor (FDR) system in specific time by quench protection system (QPS). In the previous research, the design made of 1 mm SUS304 has a bad cooling effect due to the narrow wind channel. So, the updated design concerning the cooling problem as well as the stray inductance is asked. The updated FDR system focuses on the basis of solving thermal and inductance proportional inverse problem. The scaled model machine is developed to testify the design rationality. With the update, the newly developed FDR system can provide less heat accumulation and accelerate up the cooling-down speed without bringing more stray inductance.

聚变技术综合研究设施快速放电电阻系统更新

当失超发生时，超导磁体中存储的能量需要通过失超保护系统（QPS）在特定时间内转移并消耗到快速放电电阻（FDR）系统。在之前的研究中，采用1mm SUS304制成的设计，由于风道狭窄，冷却效果较差。因此，需要针对冷却问题以及杂散电感进行更新设计。更新后的FDR系统侧重于解决热和电感成比例反问题的基础。开发了缩比模型机来验证设计的合理性。通过更新，新开发的FDR系统可以提供更少的热量积累并加快冷却速度，而不会带来更多的杂散电感。
