Abstract

APPAREIL A RAYONS X. LE TUBE 7 EST ALIMENTE GRACE A UN TRANSFORMATEUR A HAUTE TENSION A DEUX CIRCUITS MAGNETIQUES 4 SUR LESQUELS SONT ENROULES DES ENROULEMENTS PRIMAIRE ET SECONDAIRE RESPECTIFS 3 ET 2. LES ENROULEMENTS SECONDAIRES SONT EN SERIE ET LE CIRCUIT MAGNETIQUE 4 QUI PORTE L'ENROULEMENT SECONDAIRE 2 RELIE A LA CATHODE PRESENTE UN ENROULEMENT SUPPLEMENTAIRE 8 POUR L'ALIMENTATION DE L'ELEMENT CHAUFFANT DE LA CATHODE 6. L'ALIMENTATION DES ENROULEMENTS PRIMAIRES EST TELLE QUE LES TENSIONS AUX BORNES DES ENROULEMENTS SECONDAIRES SONT SOIT EN PHASE, SOIT EN OPPOSITION DE PHASE. APPLICATION: APPAREILS DE RADIOGRAPHIE.
