Title (EN) DIFFERENTIAL PROTECTING DEVICE INCORPORATING A MEANS FOR ISOLATING A RELAY OR ANALOGOUS
(FR) DISPOSITIF DE PROTECTION DIFFÉRENTIEL INTÉGRANT UN MOYEN D'ISOLATION DU RELAIS OU ANALOGUE
Abstract:
(EN) The subject of the present invention is a differential protecting device that makes it possible to detect a fault current in an electrical apparatus, with a set of functional means (3, 3', 3", 3''') for measuring, processing, evaluating and controlling and a breaking means (4) that in particular has a characteristic braking power, that is connected to the output of said functional set (3, 3', 3", 3''') and that is intended to be triggered by the control signal, this device (1) being characterised in that it furthermore incorporates a least one selective isolating means (6) that is able and intended to electrically isolate said breaking means (4), at least with respect to said functional set (3, 3', 3", 3'''), selectively.
(FR) La présente invention a pour objet un dispositif de protection différentielle permettant la détection d'un courant de défaut dans une installation électrique, avec un ensemble de moyens fonctionnels (3, 3', 3", 3''') de mesure, de traitement, d'évaluation et de commande et, d'autre part, un moyen de coupure (4), présentant notamment une puissance de coupure caractéristique et relié à la sortie dudit ensemble fonctionnel (3, 3', 3", 3''') et destiné à être déclenché par le signal de commande, dispositif (1) caractérisé en ce qu'il intègre en outre au moins un moyen (6) d'isolation sélective apte et destiné à isoler électriquement ledit moyen (4) de coupure, au moins par rapport audit ensemble fonctionnel (3, 3', 3", 3'''), ce de manière sélective.
