摘　　要：阐述了120k J高温超导储能磁体的高温超导带选择及磁体主要参数。为确定120k J高温超导储能磁体绕组的通电方式,比较了30个高温超导双饼线圈两种连接方式在225A电流下的磁场特性。为满足杜瓦强度要求,针对120k J高温超导储能磁体杜瓦开展了结构设计及强度分析,结果表明,杜瓦满足高温超导绕组吊挂对其强度的要求。The selection of high temperature superconducting （HTS） tape and the main parameters of the 120kJ HTS Magnetic Energy Storage （HT- SMES） were presented. To decide the current supply method, the magnetic field characteristics of two connecting types of 30 HTS double pancake coils under 225A current were compared. To satisfy the mechanica/strength requirement, the structural design and mechanical analysis of the cryostat were performed. The simulating results indicate the cryostat with hanging the high temperature superconducting coil can satisfy the required mechanical strength.
