Abstract

Die Erfindung betrifft die Verbesserung eines Schalters gemäss Hauptpatent P 38 10 091. Bei diesem Schalter werden über eine Kompressionseinrichtung stromschwache Lichtbögen beblasen, wobei bei stromstarken Lichtbögen ein Verschlussorgan (8) die Kompressionseinrichtung verschliesst und eine Selbstbeblasung über einen Gasspeicherraum (9) und eine Druckkammer (3) erfolgt. The invention relates to the improvement of a switch according to the main patent P 38 10 091. This switch uses a compression device Blow low-current arcs, whereby with high-current arcs Closure member (8) closes the compression device and one Self-blowing via a gas storage space (9) and a pressure chamber (3) he follows.

Bei diesem Schalter steht nach der Unterbrechung eines stromstarken Lichtbogens heisses Gas geringer Dichte vor der Schaltstrecke. Dies ist für eine erneute Lichtbogenbeblasung von Nachteil. With this switch there is a current after the interruption Arc of low density hot gas in front of the switching path. This is for renewed arcing is disadvantageous.

Eine Bereitstellung kalten Löschgases wird auch in einer solchen Schalt­ situation dadurch bewirkt, dass ein Ventil bei der Einschaltung öffnet und dadurch eine Verbindung zwischen der Druckkammer (3) und dem Kompressions­ raum (11) schafft, wodurch frisches Löschgas aus der Schaltkammer in die Druckkammer (3) gesaugt wird und für eine erneute Lichtbogenbeblasung zur Verfügung steht. A supply of cold extinguishing gas is also used in such a switch situation causes a valve to open when switched on and thereby a connection between the pressure chamber (3) and the compression creates space (11), whereby fresh extinguishing gas from the switching chamber in the Pressure chamber (3) is sucked and for a new arcing to Available.
