SYNCHRONOUS ELECTRIC GENERATOR WITH SUPERCONDUCTING WINDINGS Russian patent published in 1997 - IPC

FIELD: electric engineering. SUBSTANCE: device has rotor 1 which has superconducting excitation winding and cryogenic temperature tank 2 and superconducting armature winding 3. Superconducting armature winding is located inside cryogenic temperature tank, which is filled with liquid cooling agent, for example with liquid helium. Superconducting screen 4 which radius is R_s is spaced from outer surface of superconducting armature winding which radius is S_aw. Ratio P_э/P_aw is in range of 1.5-1.8. Superconducting screen embraces cryogenic temperature tank. Sealed chambers 5 with deterrent valve 7 are located in liquid cooling agent. Sealed chamber is designed as torus and is located in symmetry about device axis. EFFECT: increased functional capabilities. 4 cl, 2 dwg
