PURPOSE:To provide a switch for a protective circuit, which consumes the energy accumulated in a superconductive coil at abnormality with a protective resistor, and breaks the circuit constitution to the resistor at magnetization and demagnetization work so as to improve magnetization and demagnetization property thereby obviating external control, in series with the protective resistor. CONSTITUTION:A switch 5 for a superconductive magnet protective circuit constitutes the circuit by the arc discharge generated between electrodes at the initial stage of protection, making use of the energy accumulated in a superconductive coil 1, as the circuit constitution at quenching of a superconductive coil 1 or trouble occurrence of a permanent current switch 2, and then, constitutes the circuit by fusing an electrode by the arc heat. |
