Title: Permanent current switch
Inventor: FUJIWARA SHUNSUKE
IPC: H01L39/16
Filed: 1987-10-16
Abstract: PURPOSE:To make a capacity of a freezing apparatus small and to make this apparatus lightweight by a method wherein a superconducting wire whose critical current is an electric current value which is slightly larger than a value obtained by dividing an electric current value during a normal operation of a permanent current switch by the number of parallel- connected elements is connected in series to the switching elements instead of a resistor. CONSTITUTION:In a state that an equally divided electric current flows to individual switching elements, individual electric current values of equalizing superconducting wires 2 are less than a critical current value; accordingly, their resistance value is zero. If a switching element 1-a is shifted to a normal conductor due to any disturbance, the switching element 1-a is shifted to a resistive state and its electric current becomes zero; therefore, electric current values of switching elements 1-b-1-j are increased and electric current values of current- equalizing superconducting wires 2-b-2-j exceed the critical current value; accordingly, these wires are shifted to the normal conductor and become the resistive state. When the electric current value becomes zero, the switching element 1-a is cooled and is returned to a superconducting state; the electric current values are equalized by resistance values of the current-equalizing superconducting wires 2-b-2-j. Accordingly, the electric current values of all the current-equalizing superconducting wires become less than the critical current value; these wires are returned to the superconducting state and the resistance values disappear.
