people brought of high voltage current between an installation and a superconductive btc end a temperature of a high-voltage cable

摘要

The invention relates to a current supply to the high voltage between a superconducting application (2) at low temperature (4, 2k) and a connection end (3) at room temperature (300k) of a power cable high voltage, the said supply comprising at least a superconductive element (4) to high critical temperature (77k), the means of electric conductors (5) between a first end (6) of the superconductive element (4) to high critical temperature and the connection end (3) at ambient temperature, and the electrical connection means (7) between a second end (8) of the superconductive element (4) to high critical temperature superconductive and the application (2) at low temperature, according to the invention, the conducting means (5) define a metal surface (9) comprising a first and second ends (10, 11) connected respectively with the first end (6) of the superconductive element (4) to high critical temperature and with the connection end (3) at ambient temperature, the first end (10) of the said surface being in contact with a tank (12) is filled with cryogenic fluid temperature equal to or less than 77k.
