ABSTRACT:
A superconducting coil protective system comprising a protective resistor connected in parallel to a superconducting coil for dissipating the energy stored on the superconducting coil and a normally-closed power switch for interrupting an electric current flowing from the power source to the superconducting coil in response to a quenching signal from the quenching detector. A fuse circuit, which includes a serially-connected fuse and a closure switch, is connected in parallel to the power switch. The protective system may comprise a current interrupting circuit connected in parallel to the superconducting coil and the protective resistor and a commutation switch connected in series with the protective resistor and the current interrupting circuit for allowing a commutation of a current from the superconducting coil to the current interrupting circuit in response to the quenching signal. In this case, the fuse circuit is connected in parallel to the protective resistor.
