Abstract

Dispositif pour la surveillance de la circulation du fluide réfrigérant dans les enroulements d'une machine électrique. Dans chacun des circuits de fluide réfrigérant qui sont groupés en parallèle on dispose une sonde de mesure 2 qui baigne dans le fluide réfrigérant, contenant un thermomètre à résistance 3 qui est en contact thermique avec un élément chauffant électrique 4. Dans le circuit alimentation des éléments chauffants 4 il est prévu des dispositifs grâce auxquels on fournit aux éléments chauffants 4 une puissance électrique constante. Les thermomètre à résistance 3 sont raccordés à un dispositif d'exploitation avec lequel leurs valeurs de mesure respectives peuvent être scrutées périodiquement et comparées, un signal étant déclenché sur l'appareil d'affichage, dans le cas où l'on constaterait des écarts de mesure individuelles. Application au contrôle de la température des enroulements de machines.
