Abstract:

ITER uses superconduct ing magnet feeder system to transmit current, liquid helium and instrumentation cables, which are needed for magnet coils. To protect magnet system, feeders also need to extract large magnetic store energy from coil when the coil quenched. The structures and the design of ITER superconducting feeder system, which is an important reference to the feeder design for other superconducting magnet system, are described.

Key words: Feeder;Magnet, Superconduct ing bus bar, Double insulation

摘要：

ITER( 国际热核试验堆) 采用超导馈线系统传输磁体线圈所需电流、冷却液及数据信号, 并在失超等异常情况, 通过馈线转移磁体能量, 以保护整个磁体系统。介绍了国际热核试验堆超导馈线系统的结构及设计情况, 为同类型超导磁体的馈线设计提供了有益的参考。
