Abstract:

In EAST (experimental advanced superconducting tokamak), power supplies are connected to suerconducting magnets by high temperature superconducting current leads(HTSCL). In order to reduce the costs in the course of experiments, hybrid type of current leads were selected．Two toroidal field HTSCL were tested, The results can satisfy the design requirement．

Key words: Toroidal field(TF) magnets, High temperature superconductor( HTS), Current leads

摘要：

在全超导磁约束核聚变装置EAST中，采用高温超导电流引线将处于室温的电源连接处于超临界氦温区的超导磁体上。为降低实验过程中的运行成本，EAST装置中纵场磁体的电流引线采用混合式结构。电流引线测试结果表明引线符合设计要求。
