Device used in superconductor technology

Abstract

In a superconducting current limiter 1, in the limiting state pressure waves which may damage the superconductor are produced as a result of the evaporation of cooling liquid. According to the invention, the current limiter is not immersed in a cooling liquid, but rather is brought into thermal contact with a cooling fluid 22 which does not undergo a phase transition at over the operating temperature and therefore does not evaporate in the limiting state. A refrigeration reservoir 21, which may be the condensed phase of a gaseous cooling fluid or a cryogenic cooler, determines the operating temperature of the current limiter. One advantage is that it is now possible for a plurality of plate-like current-limiter modules 10, 10′ of unlimited size to be arranged next to one another in the cooling fluid 22.
