PATENTANSPRÜCHE:PATENT CLAIMS: i. Druckluftschalter, gekennzeichnet durch eine Anordnung zur Zufuhr der Druckluft zum Schalter, bestehend aus zwei oder mehreren parallel geschalteten Blasventilen, die gleichzeitig öffnen und Druckluft vom- Druckluftbehälter zu den Unterbrechungsstellen strömen lassen, die aber nach Löschung des Lichtbogens unmittelbar schließen mit Ausnahme eines Ventils, das offen bleibt und genügend Luft zur Verhinderung der Wiederzündung des Lichtbogens durchläßt, bevor ein in Reihe mit der Leistungstrennstelle angeordneter Trennschalter geöffnet wird.i. Compressed air switch, characterized by an arrangement for supplying the compressed air to the Switch consisting of two or more blow valves connected in parallel that operate simultaneously Open and compressed air flow from the compressed air tank to the interruption points which, however, close immediately after the arc is extinguished, with the exception of a valve, that remains open and enough air to prevent the arc from re-igniting lets through before a circuit breaker arranged in series with the power disconnection point is opened. " 2. Anordnung nach Anspruch i, dadurch gekennzeichnet, daß sämtliche Blasventile elektromagnetisch betätigt sind und -daß in Reihe mit 1°° den Betätigungsstromkreisen aller Blasventile außer einem 'ein pneumatisch gesteuerter Öffnungskontakt angeordnet ist, der durch Druckluft aus der Druckluftleitung über einen eine Verzögerung erzielenden Druckluftbehälter betätigt wird."2. Arrangement according to claim i, characterized in that that all blow valves are operated electromagnetically and that in series with 1 °° the actuation circuits of all blow valves except for one 'a pneumatically controlled opening contact is arranged, the compressed air from the compressed air line via a one Delay achieving compressed air tank is actuated.
