CRYOSTAT FOR ELECTRICAL DEVICES SUCH AS SUPERCONDUCTING CURRENT LIMITERS AND ELECTRICAL MACHINES SUCH AS TRANSFORMERS, MOTORS, GENERATORS AND ELECTRICAL MAGNETS WITH A SUPERCONDUCTING WINDING

摘要

The invention relates to an instant tripping device for short circuits in electrical DC and AC networks of surface and underwater vessels, especially combat vessels, and offshore installations. The aim of the invention is to improve a device of this type in such a way as to reduce the effects of thermal and dynamic stresses, due to physical factors, that occur during short circuits as far as possible and to increase availability and manoeuvrability. To this end, the instant tripping device has at least one high-temperature superconducting current limiter (3).
