Abstract

Perfectionnement aux joints électriques pour systèmes de signalisation ferroviaire. Le circuit de voie C utilisant les rails comme conducteurs est créé par la mise en oeuvre d'un joint électrique sensible à des signaux électriques d'une fréquence unique. Entre des blocs d'accord BF, le joint comporte des boucles inductives IF reliées à des moyens emetteurs et récepteurs de ladite fréquence. Un organe de commande RC est activé par les signaux de fréquence F. Le diagramme DRC montre le fonctionnement du relais RC au franchissement du circuit C par un essieu 3. De nombreuses variantes sont possibles. Application : systèmes de signalisation ferroviaire
