Abstract

Die Erfindung betrifft einen Schütz für Gleichstrom- und Wechselstrombetrieb mit mindestens einer Kontaktstelle mit einem Festkontakt und einem beweglichen Kontakt, mindestens einem benachbart zu der Kontaktstelle angeordneten Permanentmagneten zur Erzeugung eines permanentmagnetischen Blasfelds und mindestens einer benachbart zur Kontaktstelle angeordneten Spule zur Erzeugung eines elektromagnetischen Blasfelds, zur Blasung eines beim Öffnen der Kontaktstelle entstehenden Lichtbogens in mindestens eine Löscheinrichtung. Es soll ein Schütz bereitgestellt werden, der ein schnelles und sicheres Trennen der Kontakte und somit auch ein schnelles und sicheres Erlöschen der Schaltlichtbögen ermöglicht und dabei einen einfachen konstruktiven Aufbau und eine einfache Herstellung ermöglicht. Hierzu weist der Schütz mindestens eine weitere Kontaktstelle auf, wobei die beweglichen Kontakte auf einer Kontaktbrücke angeordnet sind, benachbart zu jeder Kontaktstelle mindestens ein Permanentmagnet angeordnet ist und die den beiden Kontaktstellen zugeordneten Permanentmagneten in entgegengesetzte Richtungen polarisiert sind.

The invention relates to a contactor for DC and AC operation with at least one contact point with a fixed contact and a movable contact, at least one adjacent to the contact point arranged permanent magnet for generating a permanent magnetic blowing field and at least one adjacent to the contact point arranged coil for generating an electromagnetic blow field Blowing a resulting arc when opening the contact point in at least one extinguishing device. It should be provided a contactor, which allows a quick and secure disconnection of the contacts and thus a quick and safe extinction of the switching arcs, while allowing a simple structural design and ease of manufacture. For this purpose, the contactor on at least one further contact point, wherein the movable contacts are arranged on a contact bridge, adjacent to each contact point at least one permanent magnet is arranged and the two contact points associated permanent magnets are polarized in opposite directions.
