SUPERCONDUCTING SWITCH Russian patent published in 1997 - IPC

FIELD: devices for control of such objects as chemical reactors, power supply units of nuclear power plants. SUBSTANCE: conductor is made from high-temperature superconducting material which critical temperature is greater than liquid nitrogen boiling point. It is designed as ribbon, wire, film or heavy ceramic blank. Cryogenic liquid is cooling agents which boiling point is less than critical temperature of high-temperature superconductor. Solenoid which is made from superconducting or non-superconducting wire or ribbon is used as magnetic field source. In addition conductor circuit has additional input channel for control current signal. Magnetic field source circuit has additional input channel for reference direct current. EFFECT: increased functional capabilities. 2 cl, 2 dwg
