Title (EN) MAGNETIC CIRCUIT WITH LOW RADIATED MAGNETIC FIELD, PARTICULARLY FOR A HIGH VOLTAGE TRANSFORMER SUPPLYING A CATHODE TUBE
(FR) CIRCUIT MAGNETIQUE A FAIBLE CHAMP MAGNETIQUE RAYONNE, EN PARTICULIER POUR UN TRANSFORMATEUR HAUTE TENSION ALIMENTANT UN TUBE CATHODIQUE
Abstract:
(EN) In order to reduce the magnetic field radiated by a high voltage transformer, the air gap is arranged inside the winding (9), a distance piece (8) providing for the mechanical rigidity of the magnetic circuit (2, 3) which is assembled by cold sticking. Application to television sets.
(FR) Pour diminuer le champ magnétique rayonné par un transformateur haute tension, on dispose l'entrefer à l'intérieur du bobinage (9), une cale d'épaisseur (8) assurant la rigidité mécanique du circuit magnétique (2, 3) qui est assemblé par collage à froid. Application: téléviseurs.
