Abstract

L'invention a pour objet des dispositifs pour contrôler en permanence le bon fonctionnement de circuits électriques comportant des appareils ayant une consommation normale déterminée. Un dispositif selon l'invention pour contrôler un circuit 1 alimenté par une source de courant alternatif 2 comporte un transformateur 4a, 4b, qui délivre un courant 12, un convertisseur 5 qui convertit 12 en une tension V, un oscillateur astable 6 qui convertit V en une fréquence vocale f, proportionnelle à V, un oscillateur à diapason 8 qui émet une frequence constante F, un mélangeur de fréquences 7, un filtre à diapason 9 qui présente une bande passante très étroite centrée sur F+fo ou sur F-fo, un amplificateur, un redresseur 10, un relais Il et un circuit 13 qui surveille l'intensité dans le circuit de charge d'un condensateur 14 qui fait partie du convertisseur 5. Une application est le contrôle des feux de signalisation ferroviaires fixes ou clignotants.
