Abstract

L'INVENTION SE RAPPORTE A UN APPAREIL INDUCTIF ELECTRIQUE REFROIDI PAR LA VAPORISATION D'UN LIQUIDE DIELECTRIQUE A L'INTERIEUR D'UNE ENCEINTE QUI CONTIENT UN ASSEMBLAGE D'UN NOYAU MAGNETIQUE ET DE BOBINAGES ET QUI EST PRATIQUEMENT REMPLIE, SEULEMENT DANS LES SITUATIONS DE CHARGE NULLE OU DE CHARGES NULLES VIRTUELLES, D'UN DIELECTRIQUE GAZEUX INCONDENSABLE A TRANSFERER DANS UN RESERVOIR D'EMMAGASINAGE LORSQUE L'APPAREIL ATTEINT SES CONDITIONS DE FONCTIONNEMENT NORMAL. LE VOLUME NECESSAIRE DU RESERVOIR D'EMMAGASINAGE 58 EST PROPORTIONNEL AU VOLUME LIBRE DE L'ENCEINTE 12 ET AU VOLUME DU LIQUIDE DIELECTRIQUE 42 DISPOSE A L'INTERIEUR DE CETTE DERNIERE, LA PAROI INFERIEURE DE L'ENCEINTE EST MENAGEE AVEC UNE PARTIE EN CANAL CREUX 70 QUI RECOIT UNE PARTIE DE CULASSE INFERIEURE 28 DE L'ASSEMBLAGE DE NOYAU MAGNETIQUE ET DES BOBINAGES 22 ET DEFINIT UN PUISARD 78 POUR LE LIQUIDE DIELECTRIQUE, L'AGENCEMENT ETANT TEL QUE DE REDUIRE LA QUANTITE DE LIQUIDE DIELECTRIQUE UTILISE ET LE VOLUME LIBRE DE L'ENCEINTE, MINIMISANT DE CE FAIT LE VOLUME NECESSAIRE DU RESERVOIR D'EMMAGASINAGE 58. APPLICATION AUX TRANSFORMATEURS.
