ABSTRACT:
There is disclosed a superconducting switch including two superconducting coils wound on a common bobbin wherein these coils have the same critical current value, and are connected in parallel so that magnetomotive forces which are the same in magnitude and opposite to each other in direction are produced. This superconducting switch is non-inductive and responds to an overcurrent to securely operated at a high speed. There is also disclosed a current limiter including a current limiting coil connected in parallel with the superconducting switch used as a trigger coil. The superconducting switch exists within a magnetic field produced by the current limiting coil. There is further disclosed a current limiter such that the current limiting coil is constructed to be of non-inductive type using two coils, and a superconducting switch is connected to either of these coils.
