Beschreibung
Zusammenfassung:	PURPOSE:To provide a superconducting apparatus which can open a permanent current switch at quite high speed and a highly efficient superconducting energy storing apparatus which can instantaneously accommodate for system disturbance with substantially no energy loss. CONSTITUTION:The invention comprises a superconducting apparatus having a permanent current switch 1, which opens upon conduction of a current higher than a critical level, connected in parallel with a superconducting coil 3 and a superconducting energy storing apparatus at least provided with a function for opening the permanent current switch 1, which has been closed in order to feed a permanent current to the superconducting coil 3, upon conduction of a current higher than a critical level at a time point when the superconducting coil 3 is stored with set energy through an exciting power supply 7.
