Title (EN) DIFFERENTIAL PROTECTION DEVICE FOR DETECTING A FAULT CURRENT
(FR) DISPOSITIF DE PROTECTION DIFFERENTIELLE POUR LA DETECTION D'UN COURANT DE DEFAUT
Abstract:
(EN) The subject of the present invention is a differential protection device (1) for detecting a leakage or fault current in an electrical installation. Said device (1) comprises, on the one hand, a transformer with a ferromagnetic core (T), with a primary consisting of at least two of the aforementioned conductors (P1, P2, P3, N) and with at least one secondary winding (BS1, BS2), and, on the other hand, at least one processing and control circuit (ETC) suitable for processing the signal induced across the terminals of the secondary in the event of a fault and for controlling an electromagnetic actuator (MC). Device (1) characterized in that the transformer (T) comprises two separate secondary windings (BS1 and BS2), in that the processing and control circuit (ETC) is connected to the terminals of a first secondary winding (BS1), and in that a passive circuit (CP) comprising at least one inductor (L) as well as at least one resistor (R) and/or at least one capacitor (C) in series, is connected to the terminals of the second secondary winding (BS2).
(FR) La présente invention a pour objet un dispositif (1) de protection différentielle permettant la détection de courant de fuite ou de défaut dans une installation électrique. Ledit dispositif (1) comprend, d'une part, un transformateur à noyau ferromagnétique (T), avec un primaire constitué par au moins deux 5 des conducteurs (P1, P2, P3, N) précités et avec au moins un bobinage secondaire (BS1, BS2) et, d'autre part, au moins un circuit de traitement et de commande (ETC) adapté pour traiter le signal induit aux bornes du secondaire en cas de défaut et pour commander un actionneur électromagnétique (MC). 10 Dispositif (1) caractérisé en ce que le transformateur (T) comporte deux bobinages secondaires (BS1 et BS2) distincts, en ce que le circuit de traitement et de commande (ETC) est relié aux bornes d'un premier bobinage secondaire (BS1), et en ce qu'un circuit passif (CP) comprenant une inductance (L) au moins, ainsi qu'au moins une résistance 15 (R) et/ou au moins un condensateur (C) en série, est relié aux bornes du second bobinage secondaire (BS2).
