【摘要】：由于其高临界电流密度以及优越的机械性能和电磁特性,第二代高温超导带材(也叫涂层导体)在高温低场的电力传输和低温高场下的磁体应用具有广阔的应用前景。在电力传输的低场应用中,高温超导导体在低电压大容量场合需要几千安培甚至上万安培的传输电流。在大型高场磁体应用方面,为了避免由于过高电感在磁体失超和快速关断过程中的感应高压问题,大载流容量、高电流密度高温超导导体在运行于4.2K及以下温度的大型高场超导磁体方面具有很好的应用前景。近年来,基于第二代高温超导带材,国际上相继提出了几种高载流容量的高温超导导体,本文介绍几种高温超导导体的结构及研发现状和进展,并对其结构、性能和工艺进行简单的比较和评述。
[Abstract]:Due to its high critical current density and superior mechanical properties and electromagnetic characteristics of HTS tapes (also called the second generation of coated conductors) has broad application prospects in the field of high temperature and low power transmission and low temperature under high field magnet applications. In the low field application of power transmission, high temperature superconducting conductor to thousands or even tens of thousands of amperes a transmission current in low voltage and large capacity applications. In a large high field magnet applications, in order to avoid the high inductance quench and fast turn off process in the high voltage induction magnet, large current carrying capacity, high current density and high temperature superconductor has good application prospect in the running in 4.2K and temperature large high field superconducting magnets. In recent years, the second generation of high temperature superconducting tapes based on international, have put forward several kinds of high temperature superconducting conductor with high current carrying capacity, this paper introduces several kinds of high temperature superconductor The structure, research and development status and progress of the conductor are made, and its structure, performance and process are briefly compared and commented.
