Superconducting device has refrigerant mixture supplied to hollow space in winding support for superconductive winding provided by several components with differing condensation temperatures

摘要

The superconducting device (2) has a rotor (5) provided with at least one superconducting winding (10) having conductors arranged in a heat-conductive winding support (9) having a central hollow space (12), coupled to an external refrigerant condenser unit (18) which is connected to a cold head (16) of a refrigeration system. The refrigerant is provided as a mixture of several components having differing condensation temperatures.
