Description

Einrichtung zum funkenlosen öffnen und Schließen eines Wechselstromkreises Bekannt sind Einrichtungen zum funkenlosen Öffnen und Schließen von Gleichstromkreisen. Bei diesen Anordnungen ist parallel zur Unterbrechungsstelle ein beliebig ausgebildeter Löschkreis angeordnet: Der Erfindung liegt die Aufgabe zugrunde, auch einen Wechselstromkreis ohne Funkenbildung zu unterbrechen. Zu diesem Zweck werden parallel undsymmetrisch zuderWechselstrom führenden Unterbrechungsstelle zwei Löschkreise angeordnet. jeder dieser Löschkreise besteht in an sich bekannter Weise aus einer Reihenschaltung von Kondensator und Gleichrichter, wobei in ebenfalls an sich bekannter Weise entweder der Kapazität oder der Sperrzelle ein Widerstand parallel geschaltet ist.Device for sparkless opening and closing of an alternating current circuit Devices for sparkless opening and closing of direct current circuits are known. In these arrangements, an arbitrarily designed one is parallel to the interruption point Arranged extinguishing circuit: The invention is based on the object, also an alternating current circuit without interrupting sparking. To do this, be parallel and symmetrical two extinguishing circuits are arranged at the point of interruption leading to alternating current. everyone this quenching circuit consists of a series circuit in a manner known per se of capacitor and rectifier, either in a manner also known per se a resistor is connected in parallel to the capacitance or the blocking cell.

Der Erfindungsgegenstand soll an Hand der Zeichnung näher erläutert werden. Der den zu unterbrechenden Wechselstrom führende Stromkreis ist hier mit i bezeichnet. Symmetrisch zur Unterbrechungsstelle 2 sind, wie aus der Zeichnung ersichtlich, zwei Löschkreise angeordnet. Die Löschkreise enthalten je eine Kapazität 4a bzw. 4b, mit denen je eine Sperrzelle 3 a bzw. 3 b in Reihe geschaltet ist. Parallel zu dem Kondensator eines jeden Löschkreises oder aber zum Gleichrichter liegt ein Widerstand 5 ° bzw. 5 b.The subject of the invention is to be explained in more detail with reference to the drawing. The circuit carrying the alternating current to be interrupted is denoted here by i. As can be seen from the drawing, two extinguishing circles are arranged symmetrically to the interruption point 2. The quenching circuits each contain a capacitance 4a or 4b, with each of which a blocking cell 3 a or 3 b is connected in series. A resistor 5 ° or 5 b is parallel to the capacitor of each quenching circuit or to the rectifier.

Mit einer Anordnung gemäß der Erfindung kann die Unterbrechungsstelle, beispielsweise der Kontakt eines Schnellreglers; frei von Wanderung und Abbrand gemacht werden.With an arrangement according to the invention, the interruption point, for example the contact of a fast regulator; free from migration and burnup be made.
