我国低温系列超导电缆的应用
|
摘要
低温系列超导电缆是超导磁体系统的重要组成部分,其超导磁体线圈均采用CICC(Cable-In-Conduit Conductors管装电缆导体)或卢瑟福电缆等绕制而成。目前,ITER(International Thermo nuclear Experimental Reactor)装置、强磁场、加速器等大科学装置所采用的超导电缆都使用Nb Ti和Nb3Sn低温超导材料。我国通过自主研发,已掌握了低温系列超导电缆的关键技术。讨论了超导电缆的基本绞制参数,介绍了低温超导电缆的种类以及低温超导电缆的国内发展状况与应用。
Cryogenic series superconducting cable is an important part of superconducting magnet system. The superconducting magnet coils are made of CICC( Cable-In-Conduit Conductors) or Rutherford cables. At present, superconducting cables used in large scientific devices such as ITER( International Thermo nuclear Experimental Reactor)devices,strong magnetic fields and accelerators are all made from Nb Ti and Nb3 Sn cryogenic superconducting materials. China has mastered the key technologies of cryogenic series superconducting cables through independent research and development. The paper discusses the basic cabling parameters of superconducting cables,describes the types,domestic development and application of cryogenic superconducting cables.
