Electrical Current Transmission by dc Magnetic Coupling in High Tc Superconductors

本课题研究高温、Tc （77K）超导材料。本文研究了一种利用直流磁场连接的超导直流变压器链在这些材料中通过直流磁耦合传输电流的新方法。本文将首先使用普通绝缘超导体（如引线）来探索所提出的连接方案的实际局限性，并在模拟负载条件下测试其在液氦中的传输效率。接下来将在液氮环境下使用高Tc超导氧化物陶瓷材料进行类似的实验。

This project deals with high temperature, Tc (77K) superconducting material. It deals with a novel method of current transmission by D.C. magnetic coupling in these materials by using a chain of superconducting D.C. transformers linked by a D.C. magnetic field. The practical limitations of the proposed linkage scheme will be explored by initially using an ordinary insulated superconductor, such as lead wire, and test its power transmission efficiency at liquid helium under simulated load conditions. This will be followed by conducting similar experiments using the high Tc superconducting oxide ceramic material at liquid nitrogen.
