【摘要】 国际受控热核聚变试验堆由18个D形环向场线圈、6个中心螺管线圈、6个圆形极向场线圈和18个校正场线圈组成巨大的超导磁体系统.为大幅度减小磁体系统的低温制冷设备投资和日后的运行费,采用容量分别为68、52、45和10kA总共30对高温超导电流引线馈电.不仅电流容量特大、安全性要求特高,而且还需承受低真空下巴申放电条件的30kV直流高电压.本文介绍68kA电流引线的相关设计和研发.更多还原

【Abstract】 A huge superconducting magnet system for International Thermal-nuclear Fusion Reactor (ITER) consists of 18 D-shaped toroidal coils, 6 center solenoid coils, 6 round poloidal coils and 18 correction coils. To reduce the costs for the cryoplant and its operation obviously, 30 pairs of HTS current leads will be applied and the rated currents are 68, 45, 52 and 10 kA, respectively. The leads must withstand DC 30 kV test and meet other safety requirements. The paper describes the design and R&D on a 68 kA current lead.更多还原
