自2004财政年度以来，使用高温超导（HTS）线圈的SMES的开发一直作为日本的国家项目进行。该项目的目标是通过HTS-LTS“混合”线圈系统获得比LTS线圈系统大约两倍的正常能量密度。高温超导线圈由16个双饼线圈组成，双饼线圈缠绕有Bi 2212卢瑟福型电缆。高温超导线圈在液氦浴中工作于4.2K，最大磁场为8.9T。在我们制作混合线圈系统之前，我们使用高温超导实验线圈验证了设计问题。本文讨论了利用实验线圈进行的机械压缩试验、直流运行试验和热失控试验。
Development of the SMES using high temperature superconducting (HTS) coil has progressed as a Japanese national project since FY 2004. The objective of the project is to obtain around twice the normal energy density via an HTS-LTS "hybrid" coil system compared to an LTS coil system. The HTS coil is composed of sixteen double-pancake coils and the double-pancake coil is wound with a Bi2212 Rutherford-type cable. The HTS coil is operated at 4.2 K in liquid helium bath with the LTS coil, and operated at maximum field of 8.9 T. Before we made a hybrid coil system, we verified the design issues using HTS experimental coils. In this paper mechanical compression tests, DC operation tests and thermal runaway tests using the experimental coils are discussed.
