Abstract

Dispositif d'alimentation en énergie électrique d'un four à arcs, avec un transformateur de four alimentant les électrodes et des moyens de détection d'un court-circuit accidentel dans le four. Le transformateur de four est connecté au réseau par un groupe tournant à un moteur accouplé à au moins une génératrice. La régulation agit, à partir de la mesure de la puissance fournie par la génératrice, sur l'excitation de la génératrice pour faire varier la tension délivrée dans un sens s'opposant aux variations mesurées de puissance. L'invention s'applique à la métallurgie de l'acier.
