Abstract

Un disjoncteur de circuit muni d'un transformateur de courant pour alimenter des dispositifs électroniques d'unité de déclenchement et détecter des courants élevés et faibles comprend un cœur présentant des laminations solides et écartées. Le disjoncteur comprend un ensemble d'ajustement permettant de traduire des réglages de cadran décimal en niveau de déclenchement stockés en mémoire. Un algorithme de compensation de température ajuste des points de déclenchement en réponse à des variations de température. Un schéma d'activation de déclenchement redondant nécessite au moins qu'une condition de pré-déclenchement soit satisfaite avant que le solénoïde de déclenchement soit activé. Un système de régulation de tension d'alimentation comprend un circuit d'énergie stockée. Un microcontrôleur reconfigurable exécute un algorithme de déclenchement synchronisé temporellement. Le disjoncteur se déclenche conformément à une courbe de déclenchement divisée en trois zones de protection. Un logiciel détecte si un courant primaire dépasse chaque zone est exécuté en parallèle ou simultanément, fournissant une détection de déclenchement instantanée redondante. Un procédé d'étalonnage utilise une chaîne de signal qui comprend un transformateur de courant, une résistance de charge, un circuit d'énergie stockée et un contrôleur.
