Description

Es sind elektrische Schalter bekannt, bei denen zu einer oder mehreren Leistungsunterbrechungsstellen ein Parallelstromweg vorhanden ist, in welchem eine weitere lichtbogenfrei öffnende Unterbrechungsstelle für einen über Schaltwiderstände fließenden Reststrom angeordnet ist. Bei diesen Schaltern wird zunächst die Leistungsunterbrechungsstelle und dann die Reststromunterbrechungsstelle geöffnet, wobei letztere von einem Druckmittel betätigt und auch isoliert wird.There are electrical switches known in which to one or more Power interruption points, a parallel current path is available in which a further arc-free opening interruption point for one via switching resistors flowing residual current is arranged. With these switches, the first point is the power interruption point and then the residual flow interruption point opened, the latter being operated by a pressure medium operated and also isolated.

Die Erfindung betrifft einen druckmittelbetriebenen elektrischen Stromunterbrecher, insbesondere einen Freistrahldruckgasschalter, bei dem gemäß der Erfindung mindestens eine vor der Leistungstrennstelle öffnende druckmittelbetätigte Parallelschaltstelle vorhanden ist; die imAüsschaltzustand durch das Druckmittel ohne bzw. ohne nennenswerte Druckmittelabströmung isoliert wird. Der durch die Erfindung erreichte Vorteil besteht darin, daß die Kontakte der Leistungsunterbrechungsstelle für geringere Stromstärken ausgebildet werden können, wie es ohne das Vorhandensein der Parallelschaltstelle nicht möglich wäre. Es ergibt sich dadurch eine höhere Schaltgeschwindigkeit bei kurzzeitigen Stromunterbrechungen. Die Parallelschaltstelle wird zweckmäßig an der Außenseite eines vorzugsweise vertikal angeordneten Tragisolators angebracht. Man kann aber auch, wie bereits für Leistungsschaltstellen vorgeschlagen wurde, die Schaltstellen zwischen ringförmigen Druckgasbehältern anordnen, die zugleich als Steuerelektroden für die Feldvergleichsmäßigung an den Unterbrechungsstellen verwendet sind.The invention relates to a pressure medium-operated electrical circuit breaker, in particular a free jet pressure gas switch, in which according to the invention at least a pressure-medium-operated parallel switching point that opens upstream of the power disconnection point is available; those in the switched-off state by the pressure medium without or without any noteworthy Pressure medium outflow is isolated. The advantage achieved by the invention is there in that the contacts of the power interruption point for lower currents can be designed as it is without the presence of the parallel switching point would not be possible. This results in a higher switching speed at brief power interruptions. The parallel switching point is expediently at the Outside of a preferably vertically arranged support insulator attached. Man but can also, as has already been proposed for power switching points, the Arrange switching points between ring-shaped pressurized gas containers, which are also used as Control electrodes are used for field equalization at the interruption points are.

Die Zeichnung zeigt ein Ausführungsbeispiel eines Schalters nach der Erfindung.The drawing shows an embodiment of a switch according to the Invention.

Auf dem zweckmäßig als Druckgasbehälter ausgebildeten Unterteil i stehen die Isolatoren 2 und 3. Der Isolator 2 -ist drehbar und trägt ein Trennmesser T. Der feststehende Isolator 3 trägt die aus zwei Freistrahllöschköpfen gebildete Leistungsunterbrechungsstelle A und die Parallelschaltstelle B. Die Stromanschlüsse des Schalters sind mit 4 und 5 bezeichnet. Beim -/-Uschaltvorgang erfolgt die Leistungsunterbrechung an der Trennstelle A, nachdem die Schaltkontakte an der Parallelschaltstelle B durch Druckluft getrennt und isoliert wurden. Nach der Lichtbogenlöschung an der Stelle A öffnet das Trennmesser T. Nach Abstellen der Druckluftzufuhr schließen sich die Trennstellen A und B wieder. Das Einschalten kann durch Einlegen des Trennmessers T bei geschlossenen Kontakten A und B erfolgen. Man kann aber auch das Trennmesser einlegen, nachdem zuvor die Kontakte A und B geöffnet wurden, und danach die Kontakte A und B wieder schließen. Dies hat den Vorteil, d@aß die Einschaltung ebenfalls unter Beblasung der Kontakte möglich ist.The insulators 2 and 3 stand on the lower part i, which is expediently designed as a pressurized gas container. The insulator 2 -is rotatable and carries a cutting knife T. The stationary insulator 3 carries the power interruption point A formed from two free jet extinguishing heads and the parallel switching point B. The power connections of the switch are included 4 and 5 designated. During the - / - switching process, the power is interrupted at separation point A after the switching contacts at parallel switching point B have been separated and isolated by compressed air. After the arc has been extinguished at point A , the cutting knife T opens. After the compressed air supply has been switched off, the cutting points A and B close again. It can be switched on by inserting the cutting knife T with contacts A and B closed. But you can also insert the cutting knife after the contacts A and B have been opened and then the contacts A and B close again. This has the advantage that switching on is also possible while blowing the contacts.
