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.

本项目研究高温Tc（77K）超导材料。它涉及一种新的方法，电流传输的直流磁耦合在这些材料中使用的超导直流变压器链连接的直流磁场。建议的链接方案的实际限制将探索最初使用一个普通的绝缘超导体，如引线，并测试其功率传输效率在模拟负载条件下的液氦。随后将在液氮中使用高Tc超导氧化物陶瓷材料进行类似的实验。
