摘要：可拆卸高温超导磁体被认为是降低核聚变反应堆建造和维护成本的一种方法。对BSCCO 2223高温超导电缆的对接接头进行了研究，其中电缆的横截面是机械连接的。在以往的研究中，采用数值分析的方法对对接接头中对接表面的应力分布进行了评估。结果表明，获得节理表面均匀应力分布对减小节理阻力具有重要意义。因此，本研究通过结构分析和试验，对几种荷载体系下高温超导索的节点阻力与内部应力分布的关系进行了评价。在此基础上，提出了一种能使节理表面应力分布均匀，避免应力集中的有效加载系统。
Abstract Remountable HTS magnets are suggested for as a method to reduce the construction and maintenance costs of a fusion reactor. Butt joints of BSCCO 2223 HTS cable, where cross-sections of the cable are jointed mechanically, have been researched for the new concept. In a previous study, stress distribution on the joint surface in the butt joint was evaluated by numerical analysis. The result showed the importance of obtaining homogeneous stress distribution on the joint surface to reduce the joint resistance. In this study, therefore, the relations between the joint resistance and the stress distribution inside the HTS cable is evaluated for several loading systems by structural analysis and experiment. Based on the result, an efficient loading system is suggested, which can achieve the uniform stress distribution on the joint surface and can avoid the stress concentration.
