Power fuse and aircraft comprising such a power fuse
A cryogenic fuse comprising a superconducting element arranged in a first chamber, the first chamber containing a cryogenic fluid, the cryogenic fuse being such that the superconducting element comprises a breaker initiation zone configured to determine a melting current and the first chamber is surrounded by a second chamber, placed under vacuum. The melting current or a melting time of the breakdown initiation zone may be adjusted.
