Superconducting static machine having a magnetic circuit

摘要

A superconducting static machine having a magnetic circuit includes a magnetic circuit core at mere ambient temperature and very low (cryogenic) temperature windings (1A, 1B) and one or more magnetic circuit cores at considerably higher temperatures. The magnetic circuit core is disposed in a thermally-insulating chamber (3) which is itself disposed inside a very low temperature (9) containing the windings. The invention is particularly applicable to transformers.
