Wireless power supply system for superconducting offshore wind turbine

A wireless power supply system for a superconducting offshore wind turbine, comprising a shell, and a vacuum Dewar flask, a superconducting motor and a rotary flux-pump wireless power supply device which are arranged inside the shell, wherein

• a refrigerating apparatus is rotatably arranged inside the vacuum Dewar flask, and the refrigerating apparatus is driven to rotate by the offshore wind turbine;
• the superconducting motor comprises an armature winding fixed on an inner wall of the shell and excitation windings uniformly arranged on an outer periphery of the refrigerating apparatus;
• the rotary flux-pump wireless power supply device comprises an inner rotor and an outer rotor which are arranged opposite to each other, the inner rotor is arranged inside the vacuum Dewar flask, the outer rotor is arranged outside the vacuum Dewar flask, and the inner rotor and the outer rotor coaxially rotate with the excitation windings;
• high-temperature superconducting stator strips are provided at an outer periphery of the inner rotor and electrically connected to the excitation windings in one-to-one correspondence;
• permanent magnets are provided on one side, facing the inner rotor, of the outer rotor and in one-to-one correspondence with the high-temperature superconducting stator strips;
• the outer rotor and the inner rotor rotate differentially, the permanent magnets induce a direct-current output voltage on the high-temperature superconducting stator strips, to input a direct current to the excitation windings, so as to form a magnetic field and induce an output voltage at the armature winding of the superconducting motor.
