Abstract

L’invention concerne un dispositif servant à débrancher un fusible de ligne en cas de panne d'un élément du redresseur de contrôle d'un appareil de chauffage. Le dispositif surveille en permanence l'état de fonctionnement des éléments du redresseur de contrôle, tels qu'un SCR ou un TRIAC, utilisés dans un appareil de chauffage tel qu'une nappe chauffante électrique ou un enveloppement chaud électrique, et débranche le fusible de ligne en cas de fonctionnement anormal de l'élément du redresseur de contrôle dû à une défaillance, ce qui empêche un élément chauffant pour fil chauffant de générer en continu de la chaleur. Le dispositif vérifie si une tension d'amorçage par la gâchette destinée à activer l'élément du redresseur de contrôle est envoyée à une ligne de gâchette et si l'élément chauffant pour fil chauffant génère de la chaleur en réaction à l'apport de la tension d'amorçage par la gâchette, et débranche le fusible de ligne si l'élément chauffant pour fil chauffant génère de la chaleur même dans un état de non alimentation en tension d'amorçage par la gâchette. Cela permet ainsi de prévenir un feu imputable au fonctionnement de l'élément chauffant, indépendamment d'un signal de contrôle de la température en cas de panne de l'élément du redresseur de contrôle utilisé dans un appareil de chauffage.
