Description

Das Hauptpatent 885 zog betrifft eine Löschblechpaketanordnung für Schalter mit wenigstens einer mit einem Festkontaktpaar zusammenarbeitenden Schaltbrücke, bei der zur Entlastung der Schaltbrücke jedem Festkontakt ein Löschblechpaket zugeordnet ist. Die den Bewegungsraum der KantakbbTücka begrenzenden Endbleche tsind hierbei leitend miteinander verbunden.The main patent 885 relates to an arc stack assembly for Switch with at least one switching bridge that works together with a fixed contact pair, in the case of relieving the load on the switching bridge, each fixed contact is assigned a stack of extinguishing plates is. The end plates that limit the movement space of the KantakbbTücka are here conductively connected to each other.

Die Erfindung hat die Aufgabe, eine solche Anordnung zu verbessern, insbesondere die Kontakte noch weiter zu entlasten und die Herstellung der Lichtbogenkammern zu erleichtern. Erfindungsgemäß werden die quer zum Lichtbogen verlaufenden Blechpakete etwa parallel zur Bewegungsrichtung der Kontaktbrücke angeordnet und die Kontakte vorzugsweise mit quer zu den Blechen im Abstand von den Blechen angeordneten Fortsätzen versehen.The invention has the task of improving such an arrangement, in particular to further relieve the contacts and the production of the arc chambers to facilitate. According to the invention, the laminated cores running transversely to the arc arranged approximately parallel to the direction of movement of the contact bridge and the contacts preferably with extensions arranged transversely to the metal sheets at a distance from the metal sheets Mistake.

Hierdurch wird erreicht, daß sofort nach Öffnen der Kontakte der entstandene Lichtbogen von den Kontakten weggedrückt wird, wobei, ahne das rasche Ausdehnen des Lichtbogens zu hindern, gleichzeitig der Lichtbogen aufgeteilt und eine sichere Löschung gewährleistet wird. Man hat zwar schon vorgeschlagen, die Löschung des entsprechenden Lichtbogens in einer etwa senkrecht zur Bewegungslinie der Kontakte liegenden Löschkammer vorzunehmen, benötigte aber bei dieser Anordnung einmal zwei Löschkammern, zum anderen verhältnismäßig schwierig herzustellende zusätzliche Kontaktbleche. Ein besonderer Vorteil der vorliegenden; Erfindung ist die einfache konstruktive Anordnung der einzelnen Bleche.This ensures that immediately after opening the contacts the resulting Arc is pushed away from the contacts, suspecting the rapid expansion To prevent the arc, at the same time the arc is split and safe Deletion is guaranteed. It has already been suggested that the corresponding arc in an approximately perpendicular to the line of movement of the contacts to undertake lying extinguishing chamber, but once needed two with this arrangement Arcing chambers, on the other hand, additional contact plates that are relatively difficult to manufacture. A particular advantage of the present; Invention is simple constructive Arrangement of the individual sheets.

An Hand der Zeichnung wird ein Ausführungsbeispiel schematisch erläutert.An exemplary embodiment is explained schematically using the drawing.

Das Kontaktpaar r, 2 arbeitet mit der Schaltbrücke 3 zusammen. Beim Öffnen der Schaltbrücke wird der Lichtbogen in bekannter Weise senkrecht zur Bewegungsrichtung der Kontaktbrücke weggeblasen und erreicht dabei schnell die Löschbleche 4,6 bzw. 5,7. Bei Weiterbewegung der Kontaktbrücke 3 wird der entstandene Lichtbogen leicht durch die Vergrößerung des Kontaktabstandes Endblech-Kontaktbrücke von den Kontakten losgerissen.The pair of contacts r, 2 work together with the switching bridge 3. When the switching bridge is opened, the arc is blown away in a known manner perpendicular to the direction of movement of the contact bridge and quickly reaches the quenching plates 4, 6 or 5, 7. As the contact bridge 3 moves further, the resulting arc is easily torn away from the contacts by increasing the contact spacing between the end sheet metal contact bridge and the contacts.

Vorteilhaft kann es sein, die leitende Verbindung zwischen den Blechen q. und 5 durch einfache Ausbildung eines zusammenhängenden U-förmigen Bleches zu erreichen, wodurch die konstruktive Ausbildung der Löschblechpaketanordnung noch weiter vereinfacht wird.It can be advantageous for the conductive connection between the metal sheets q. and 5 by simply forming a coherent U-shaped sheet achieve, whereby the structural design of the arc stack assembly still is further simplified.
