Abstract

The circuit breaker has an arc blow coil in a cylindrical housing. The light arc rotates between two coaxial, annular electrodes in a quenching agent stream. Through the two annular electrods is slidably arranged a contact pin for contact making and breaking. The cylindrical housing contains a peripheral flow channel for the quenching agent, which forms a close circuit. The upper part of the housing is made of an insulant, while its lower part is of metal. The quenching agent preferably passes through both electrodes via a special perforation. In order to deionised the quenching agent, partitions and cooling baffles are incorporated in the flow channel.

Description

Elektrischer Leistungsschalter mit rotierendem Lichtbogen Rotating arc electric circuit breaker

Die Erfindung bezieht sich auf einen elektrischen Leistungsschalter mit einem zylindrischen Gehäuse, einer Blasspule und einem bei der Ausschaltung zwischen zwei koaxialen Ringelektroden in einem Löschmittel rotierendem Lichtbogen.The invention relates to an electrical circuit breaker with a cylindrical case, a blow-out coil and one at the turn off between two coaxial ring electrodes in an extinguishing agent rotating arc.

Durch die Rotation des Schaltlichtbogens im Druckgas, meist Schwefelhexafluorid (SF6), wird dem Lichtbogen Energie entzogen, so daß eine Löschung im Stromnulldurchgang möglich ist. Bei einem bekannten Schaltgerät dieser Bauart (ELEKTRIE, H.10, (1967), S. 364) berühren sich die Elektroden in der Einschaltstellung.Through the rotation of the switching arc in the compressed gas, usually sulfur hexafluoride (SF6), energy is withdrawn from the arc so that it is extinguished when the current passes through zero is possible. In a known switching device of this type (ELEKTRIE, volume 10, (1967), P. 364) the electrodes touch each other in the switch-on position.

Zur Ausschaltung wird die innere Elektrode (Zylinderkontakt) in eine zur äußeren Elektrode (Ringkontakt) konzentrische Lage geschwenkt. In dem so entstehenden Ringspalt rotiert der Schaltlichtbogen, durch eine dauernd im Stromkreis liegende koaxiale Blasspule getrieben, bis zur Löschung.To switch off, the inner electrode (cylinder contact) is turned into a Pivoted position concentric to the outer electrode (ring contact). In the one that arises in this way The switching arc rotates in an annular gap through a gap that is permanently in the circuit coaxial blow-out coil driven until extinguishing.

Aufgabe der vorliegenden Erfindung ist es, die Löschwirkung durch eine zusätzliche Strömung des Löschmittels zu verbessern.The object of the present invention is to achieve the extinguishing effect to improve an additional flow of the extinguishing agent.

Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Patentanspruchs 1 enthaltenen Merkmale gelöst.According to the invention, this object is achieved by the characterizing features of the patent claim 1 contained features solved.

Die Zeichnung zeigt ein Ausführungsbeispiel eines Schalters gemäß der Erfindung im Ausschaltzustand. Der schematisch im Schnitt dargestellte Schalter hat ein Gehäuse, das im oberen Teil 9 aus Isolierstoff, im unteren Teil 10 aus Metall besteht und um eine senkrechte Mittelachse kreissymmetrisch ausgebildet ist. Das Gehäuse 9,10 ist ganz oder teilweise mit einem gasförmigen oder flüssigen Löschmittel gefüllt.The drawing shows an embodiment of a switch according to of the invention in the switched-off state. The schematic in Section shown Switch has a housing that is made of insulating material in the upper part 9 and in the lower part 10 is made of metal and formed circularly symmetrical about a vertical central axis is. The housing 9,10 is completely or partially with a gaseous or liquid Extinguishing agent filled.

Im oberen Teil des Gehäuses befinden sich zwei konzentrische Ringelektroden 3,4, zwischen denen bei einer-Ausschaltung ein Schaltlichtbogen 6 brennt und durch das Magnetfeld zweier Spulen 7,8 in Rotation versetzt wird. Der Schalter hat die äußeren Anschlüsse 15,16.In the upper part of the housing there are two concentric ring electrodes 3, 4, between which a switching arc 6 burns and through when switching off the magnetic field of two coils 7,8 is set in rotation. The switch has that external connections 15,16.

Im Einschaltzustand (nicht dargestellt) fließt der Strom über den Anschluß 15, einen Ringkontakt 2, einen Schaltstift 1 und einen Ringkontakt 14 zum Anschluß 16.In the switched-on state (not shown), the current flows through the Connection 15, a ring contact 2, a switching pin 1 and a ring contact 14 for Connection 16.

Im gezeichneten Zustand (Löschphase) fließt der Strom über den Anschluß 15, eine Blasspule 7, eine zweite Blasspule 8, eine Ringelektrode 3, einen Lichtbogen 6 und eine Ringelektrode 4 zum Anschluß 16.In the drawn state (erasing phase) the current flows through the connection 15, a blowing coil 7, a second blowing coil 8, a ring electrode 3, an arc 6 and a ring electrode 4 for connection 16.

Der besondere Vorteil des Schalters gemäß der Erfindung ist darin zu sehen, daß durch den rotierenden Lichtbogen 6 und die dadurch mit rotierende Gassäule zwischen den Ringelektroden 3 und 4 die Wirkung einer Kreiselpumpe hervorgerufen wird.The particular advantage of the switch according to the invention is therein to see that by the rotating arc 6 and thereby with rotating Gas column between the ring electrodes 3 and 4 caused the effect of a centrifugal pump will.

Hierdurch setzt sich das Löschmittel während der Löschphase in Richtung der Pfeile 13 in Bewegung. Zur Erzeugung der Löschmittelströmung wird keine sonst übliche Kompressionseinrichtung benötigt. Damit der Löschmittelströmung möglichst wenig Widerstand entgegengesetzt wird, sind die Ringelektroden 3,4 mit einer Lochung 5 versehen, durch die das Löschmittel hindurchtreten kann.This causes the extinguishing agent to move towards you during the extinguishing phase the arrows 13 in motion. No other usual compression device required. So that the extinguishing agent flow as possible little resistance is opposed, the ring electrodes 3, 4 are perforated 5 provided through which the extinguishing agent can pass.

Im unteren Teil 10 des Schaltergehäuses sind Trennwände 11 und radiale Kühlbleche 12 eingebaut, die zur Entionisierung des hindurchströmenden Löschmittels dienen.In the lower part 10 of the switch housing are partitions 11 and radial Cooling plates 12 installed, which are used to deionize the extinguishing agent flowing through to serve.
