Abstract

L'INVENTION CONCERNE LES MACHINES ELECTRIQUES TOURNANTES. POUR DETECTER L'EXISTENCE D'UNE DECHARGE COURONNE DANS UNE ENCOCHE DU STATOR D'UNE MACHINE ELECTRIQUE, ON MONTE UNE ANTENNE 11 SUR L'UN DES POLES DU ROTOR 10 DE CETTE MACHINE. CETTE ANTENNE RECOIT LES SIGNAUX DE HAUTE FREQUENCE QUI RESULTENT D'UNE DECHARGE COURONNE, ET LES TRANSMET A UN DISPOSITIF D'UTILISATION 18 PAR L'INTERMEDIAIRE D'UN TRANSFORMATEUR TOURNANT QUI COMPREND UN COUPLEUR TOURNANT 14 ET UN COUPLEUR FIXE 16. APPLICATION AUX ALTERNATEURS.
