Static sealing self-quench-preventing high-temperature superconducting motor

Abstract

The invention relates to a static sealing self-quench-preventing high-temperature superconducting motor which comprises an outer stator, a first air gap, a rotor, a second air gap and a high-temperature superconducting exciting inner stator which are sequentially arranged from outside to inside. The outer stator comprises an outer stator iron core and armature coils; the rotor comprises magnetic conductive iron core blocks and non-magnetic-conductive material blocks, which are arranged at intervals; and the inner stator comprises non-magnetic-conductive winding supports, high-temperature superconductive exciting coils and magnetic conductive rings arranged outside the high-temperature superconductive exciting coils. The magnetic conductive rings not only can provide radial magnetic paths for the high-temperature superconductive exciting coils and reduce the use quantity of high-temperature superconductive wires, but also can provide tangential magnetic paths for an armature reaction magnetic field and eliminate influence of the armature reaction magnetic field on critical currents of high-temperature superconductive exciting windings. The magnetic conductive rings outside the high-temperature superconductive exciting coils have a magnetic field shielding function, so that quench caused by action of the alternating armature reaction magnetic field on the high-temperature superconductive exciting coils, can be prevented, the high-temperature superconductive exciting coils are effectively protected, and reliability of motor operation is improved.

Description

technical field [0001] The invention relates to a statically sealed self-prevention superhigh temperature superconducting motor, which belongs to the field of high temperature superconducting motors. Background technique [0002] Wind energy, as one of the most mature renewable energies with the most mature development and application technology mastered by human beings, has been increasingly concerned and highly valued by governments of various countries due to its advantages of large amount of development, wide distribution area, safety and environmental protection. Compared with onshore wind power generation, offshore wind power generation has become an important development direction in the field of wind power because of its advantages such as stable wind resources, low turbulence intensity, strong wind energy, and no occupation of land resources. For offshore wind power generation, in order to improve system power generation efficiency and reduce power generation cost p...
