Abstract

Le dispositif de stockage d’énergie comporte un transformateur rotatif (10), le transformateur rotatif comprenant une partie fixe formant un stator (11) comportant des bobines statoriques (13) reliées en série et une partie mobile formant un rotor (12) et comportant une enceinte cryogénique (24), et des bobines rotoriques (25) supraconductrices reliées en série et disposées dans l’enceinte cryogénique (24), le rotor et le stator étant coaxiaux et séparés par un entrefer de sorte qu’un champ magnétique généré par les bobines statoriques (13) induit un courant dans les bobines rotoriques (25) lors de la rotation du rotor.. L’enceinte cryogénique (24) comprend en outre un circuit de stockage d’énergie électrique (26) relié aux bobines rotoriques (25). Figure pour l’abrégé : Fig 2The energy storage device comprises a rotary transformer (10), the rotary transformer comprising a fixed part forming a stator (11) comprising stator coils (13) connected in series and a moving part forming a rotor (12) and comprising a cryogenic enclosure (24), and superconducting rotor coils (25) connected in series and arranged in the cryogenic enclosure (24), the rotor and the stator being coaxial and separated by an air gap so that a magnetic field generated by the stator coils (13) induces a current in the rotor coils (25) during rotation of the rotor. The cryogenic enclosure (24) further comprises an electrical energy storage circuit (26) connected to the rotor coils (25). Figure for abstract: Fig 2
