Die Erfindung bezieht sich auf einen Druckgasschalter mit Umlaufströmung, der mindestens eine Löscheinheit in einem rotationssymmetrischen Gehäuse aufweist, das aus einem Hohlisolator und zwei seine beiden Enden abdeckenden metallenen Kappen besteht, von denen die eine den Hochdruckbehälter und die andere den Niederdruckbehälter begrenzt und beide Behälter durch eine gemeinsame Begren-3ungswand voneinander getrennt sind, und in dem die zylindrischen Kontakte in der oder parallel zur Rotationsachse des Gehäuses angeordnet sind. Es ist ein Druckgasschalter dieser Art bekanntgeworden, bei dem sich im mittleren Teil des Hohlisolators der mit einer Bohrung versehene feste Kontakt befindet, der die gemeinsame Begrenzungswand bildet und in dessen Bohrung der zylindrische bewegliche Kontakt eingreift. Der Hochdruckbehälter wird durch die eine Kappe und den dieser Kappe zugewandten Teil des Hohlisolators und der Niederdruckbehälter durch die andere Kappe und den auf der anderen Seite des festen Kontakts befindlichen Teil des Hohlisolators gebildet.The invention relates to a pressure gas switch with circulating flow, the at least one Has extinguishing unit in a rotationally symmetrical housing, which consists of a hollow insulator and two metal caps covering both ends, one of which is the high-pressure container and the other delimits the low-pressure vessel and both vessels by a common delimiting wall are separated from each other, and in which the cylindrical contacts in or parallel to the Rotation axis of the housing are arranged. A pressurized gas switch of this type has become known, in which the fixed contact provided with a bore is located in the middle part of the hollow insulator, which forms the common boundary wall and in its bore the cylindrical movable contact intervenes. The high-pressure container is through the one cap and the part of the cap facing this cap Hollow insulator and the low pressure vessel through the other cap and the one on the other side of the Formed fixed contact located part of the hollow insulator.
Der Hohlisolator bildet also einen wesentlichen Teil des Hochdruckbehälters. Der Hohlisolator wird durch den hohen Druck des Löschgases sehr stark auf Zug beansprucht. Dieser Hohlisolator besteht aus einem keramischen Werkstoff, der bekanntlich hinsichtlich Zugkräften sehr empfindlich ist. Aus diesem Grund kann dieser bekannte Druckgasschalter nicht mit einem Löschgas sehr hohen Drucks betrieben werden, so daß er lediglich auf niedrige Gasdrücke beschränkt ist.The hollow insulator thus forms an essential part of the high-pressure container. The hollow insulator will Due to the high pressure of the extinguishing gas, it is very much subjected to tensile stress. This hollow insulator consists of a ceramic material that is known to be very sensitive to tensile forces. For this This known pressurized gas switch cannot be operated with an extinguishing gas of very high pressure so that it is limited only to low gas pressures.
Der Erfindung liegt die Aufgabe zugrunde, diesen bekannten Druckgasschalter zu verbessern und ihn so auszubilden, daß er raumsparend und mit großer Stabilität hergestellt werden kann, so daß bei ihm die Lichtbogenlöschung mit einem Gas sehr hohen Drucks erfolgen kann, ohne daß der Hohlisolator diesen hohen Drücken selbst ausgesetzt ist. Die Lösung dieser Aufgabe erfolgt gemäß der Erfindung dadurch, daß der Hochdruckbehälter durch die eine Kappe und die unmittelbar, jedoch nicht über den Hohlisolator mit ihr verbundene, vorzugsweise aus Metall bestehende Begrenzungswand und der Niederdruckbehälter durch die andere Kappe, den gesamten Hohlisolator und die Begrenzungswand gebildet wird und daß die beiden Kappen zusammen mit dem Hohlisolator eine im wesentlichen ellipsoide äußere Form besitzen, deren längere Achse mit der Rotationsachse zusammenfällt.The invention is based on the object to improve this known gas pressure switch and him to train so that it can be made space-saving and with great stability, so that with him the arc can be extinguished with a gas of very high pressure without the hollow insulator is exposed to these high pressures itself. This object is achieved according to the invention in that the high pressure container through the one cap and directly, but not through the Hollow insulator connected to it, preferably made of metal, the boundary wall and the low-pressure container is formed by the other cap, the entire hollow insulator and the boundary wall and that the two caps together with the hollow insulator have a substantially ellipsoidal outer Have a shape whose longer axis coincides with the axis of rotation.
Dadurch, daß die eine metallene Kappe mit der mit ihr verbundenen, vorzugsweise metallenen Be-Druckgasschalter mit UmlaufströmungThe fact that the one metal cap with the preferably metal loading pressure gas switch connected to it with circulating flow

grenzungswand als Hochdruckbehälter ausgebildet ist, ergibt sich der Vorteil, daß diese Kappe sehr stabil für sich hergestellt und nachträglich mit dem Hohlisolator in einfacher Weise verbunden werden kann. Infolge der Herstellung dieser Kappe und der mit ihr verbundenen Begrenzungswand aus Metall kann der sie bildende Hochdruckbehälter sehr hohe Drücke vertragen. Der Hohlisolator, die Begrenzungswand und die andere Kappe bilden den Niederdruckbehälter, der nur relativ geringen Drücken ausgesetzt ist. Die äußere ellipsoide Form der Löscheinheit läßt eine raumsparende und stabile Ausbildung der Löscheinheit zu.boundary wall is designed as a high-pressure container, there is the advantage that this cap is very can be made stable by itself and subsequently connected to the hollow insulator in a simple manner can. As a result of the production of this cap and the boundary wall connected to it made of metal the high-pressure container that forms them can withstand very high pressures. The hollow insulator, the boundary wall and the other cap form the low-pressure container, which is only exposed to relatively low pressures. The outer ellipsoidal shape of the quenching unit leaves a space-saving and stable design of the extinguishing unit.
Es sind bereits Löscheinheiten von Druckgasschaltern bekannt, die ein ellipsoides Gehäuse besitzen, das aber gänzlich anders aufgebaut ist als das Gehäuse der erfindungsgemäßen Löscheinheit und dessen kürzere Achse mit der Rotationsachse zusammenfällt. Insbesondere ist das Gehäuse der bekannten Löscheinheiten nicht aus zwei Kappen und einem Hohlisolator zusammengesetzt.There are already extinguishing units of compressed gas switches known that have an ellipsoidal housing, but which is constructed completely differently than the housing of the extinguishing unit according to the invention and whose shorter axis coincides with the axis of rotation. In particular, the housing is the known Extinguishing units not composed of two caps and a hollow insulator.
Infolge der erfindungsgemäßen Ausbildung der Löscheinheit bildet diese eine geschlossene Baueinheit, die neben einer hohen mechanischen Festigkeit eine große Isolationsfestigkeit aufweist, da die beiden Kappen durch den Hohlisolator sehr weit voneinander getrennt sind. Mehrere solche Baueinheiten lassen sich in einfacher Weise zu einem Druckgasschalter zusammenbauen.As a result of the design of the extinguishing unit according to the invention, it forms a closed structural unit, which, in addition to high mechanical strength, has great insulation strength, as the two Caps are very far separated from each other by the hollow insulator. Several such units can be easily assembled to form a gas pressure switch.
