Title
(EN) SUPERCONDUCTING GENERATOR DRIVEN BY A WIND TURBINE
(FR) GÉNÉRATEUR SUPRACONDUCTEUR ENTRAÎNÉ PAR UNE ÉOLIENNE
Abstract
(EN)
A superconducting generator includes an annular armature connectable to rotate with a rotating component of a wind turbine. A stationary annular field winding is coaxial to the armature and separated by a gap from the armature. The field winding includes superconducting coils, and there is a non-rotating support for the field winding. The non- rotating support is a torque tube. The torque tube is a member formed of a composite material, or a member formed of a plurality of segmented sections, a space frame or strut torque carrying assembly. The torque tube is connected to a thermal shield casing or a field winding housing.

La présente invention concerne un générateur supraconducteur comprenant un induit annulaire pouvant être relié afin de tourner à l'aide d'un composant rotatif d'une éolienne. Un enroulement de champ annulaire fixe est coaxial à l'induit et séparé par un espace de l'induit. L'enroulement de champ comprend des bobines supraconductrices, et un support non rotatif est destiné à l'enroulement de champ. Le support non rotatif est un tube de couple. Le tube de couple est un élément constitué d'un matériau composite, ou un élément constitué d'une pluralité de sections segmentées, une structure spatiale, ou un ensemble de support de couple d'entretoise. Le tube de couple est relié à un boîtier de protection thermique ou à un boîtier d'enroulement de champ.
