PURPOSE:To prevent the influence and propagation of normal conductive displacement by keeping each parameter of a power supply device for a plurality of electromagnetically coupled superconducting coils in predetermined relationship. CONSTITUTION:When self-inductance of a plurality of superconducting coils is represented in L1, L2...Ln, No.k and No.i mutual inductance in Mki, excitation current values in I10, I20...In0, protective resistance values in R1, R2...Rn, rated inversion voltage of a DC power supply in [E1]INV..., a resistance value per unit length of a wire rod for the superconducting coil in r, weight in m, specific heat in c, the normal temperature of a superconducting wire in T0, an allowable upper-limit temperature in TF and the dielectric strength of the superconductive coil in EKO, these values satisfy the following formula. Accordingly, the influence and propagation of normal conduction displacement can be prevented. |
