Abstract
(DE)
Elektrische Kurzschließereinrichtung (10) mit einem feststehenden und einem beweglichen Kontaktstück (12, 14), wobei die Kontaktstücke (12, 14) in einer Grundstellung voneinander beabstandet sind und in einer Kurzschlussstellung miteinander elektrisch leitend verbunden sind, einem Antrieb (16) zum Überführen des beweglichen Kontaktstücks (14) von der Grundstellung in die Kurzschlussstellung und einer Auslöseeinrichtung (18) zum Auslösen des Antriebs (16). Es ist vorgesehen, dass die Auslöseeinrichtung (18) zum Auslösen einen elektrisch angetriebenen Aktor (24) umfasst. Die Erfindung betrifft weiterhin einen Umrichter, der mindestens eine derartige Kurzschließereinrichtung (10) aufweist. Ferner betrifft die Erfindung ein entsprechendes Verfahren zum Kurzschließen von Kontaktstücken (12, 14).
(EN)
The invention relates to an electrical short-circuiting device (10) having a fixed and a movable contact piece (12, 14), the contact pieces (12, 14) being distanced from one another in a basic position and being electrically conductively connected to one another in a short-circuit position, having a drive (16) for transferring the movable contact piece (14) from the basic position into the short-circuit position, and having a trigger device (18) for triggering the drive (16). According to the invention, the trigger device (18) comprises an electrically driven actuator (24) for the triggering. The invention further relates to a converter which comprises at least one short-circuiting device (10) of this kind. The invention further relates to a corresponding method for short-circuiting contact pieces (12, 14).
(FR)
L’invention concerne un dispositif de court-circuit électrique (10) comprenant des pièces de contact fixe et mobile (12, 14), les pièces de contact (12, 14) étant espacées les unes des autres dans une position de base et étant reliées électriquement les unes aux autres dans une position de court-circuit, un entraînement (16) destiné à transférer la pièce de contact mobile (14) de la position de base à la position de court-circuit et un dispositif de déclenchement (18) destiné à déclencher l’entraînement (16). Selon l'invention, le dispositif de déclenchement (18) comprend pour le déclenchement un actionneur à commande électrique (24). L’invention concerne en outre un convertisseur qui comporte au moins un tel dispositif de court-circuit (10). L’invention concerne également un procédé correspondant de court-circuit de pièces de contact (12, 14).
