Abstract

L'invention concerne les circuits électriques de contrôle. Un circuit de contrôle de la continuité d'un segment de conducteurs électriques 10, 12 comprend essentiellement un oscillateur 36 qui est branché à un enroulement d'un transformateur 32 dont l'autre enroulement est connecté en série dans le conducteur 10. La charge du circuit oscillant de l'oscillateur est fortement réduite en cas de discontinuité dans les conducteurs contrôlés, ce qui fait apparaître une modification détectable du signal de sortie de l'oscillateur. Application aux circuits de commande des rames de véhicules automoteurs.
