Abstract

L'invention concerne un dispositif de détection d'état ouvert ou fermé d'interrupteur (I) qui comprend des moyens (1, 2, 3) pour délivrer une tension de valeur inférieure ou supérieure à une valeur de tension de référence prédéterminée (V ) selon que l'interrupteur est ouvert ou fermé et un comparateur (4) pour comparer la tension de référence prédéterminée (V ) avec la tension délivrée par lesdits moyens et délivrer un signal de comparaison (V ) ayant une valeur différente selon que l'interrupteur est ouvert ou fermé. L'invention s'applique notamment à la détection d'état ouvert ou fermé d'interrupteurs de relais de protection de transformateur à fluide diélectrique.The invention relates to an open or closed switch state detection device (I) which comprises means (1, 2, 3) for delivering a voltage of a value less than or greater than a predetermined reference voltage value (V ) depending on whether the switch is open or closed and a comparator (4) for comparing the predetermined reference voltage (V) with the voltage delivered by said means and outputting a comparison signal (V) having a different value depending on whether the switch is open or closed. The invention applies in particular to the open or closed state detection of dielectric fluid transformer protection relay switches.
