Description

Das Patent 767o58 betrifft einen Druckgasschalter mit Mehrfachunterbrechung an der Leistungsschaltstelle und mit einer dazu in Reihe liegenden Trennschaltstelle für die Spannungsisolation, bei welchem den einzelnen Leistungsunterbrechungsstellen Impedanzen parallel geschaltet sind, die so bemessen sind, .daß die Spannung auf alle Leistungsunterbrechungsstellen gleichmäßig verteilt wird und der Reststrom durch einen Schalter abgeschaltet werden kann, der ohne Druckgas isoliert. Es hat sich nun gezeigt, daß es nicht notwendig ist, jede einzelne Leistungsunterbrechungsstelle an die Steuerimpedanz anzuschließen, sondern, daß es zur Erzielung einer in vielen Fällen genügenden Vergleichmäßigung der Potentialverteilung auf alle Unterbrechungsstellen genügt, wenn die Unterbrechungsstellen für die Potentialsteuerung in Gruppen zusammengefaßt sind.The 767o58 patent relates to a pressurized gas switch with multiple break at the power switching point and with an isolating switching point in series with it for the voltage isolation, in which the individual power interruption points Impedances are connected in parallel, which are dimensioned so that the voltage on all power interruption points is evenly distributed and the residual current can be switched off by a switch that isolates without compressed gas. It has it has now been shown that it is not necessary to interrupt every single power interruption point to connect to the control impedance but that it is to achieve one in many In cases of sufficient equalization of the potential distribution to all interruption points is sufficient if the interruption points for the potential control are combined in groups are.

Gegenstand der Erfindung ist eine Weiterentwicklung des Hauptpatents, die darin besteht, daß erfindungsgemäß dieLeistungsunterbrechungsstellen eines Pols zu Gruppen zusammengefaßt und den Gruppen Impedanzen .zur Vergleichmäßigung der Spannungsverteilung auf die Unterbrechungsstellen parallel geschaltet sind.The subject of the invention is a further development of the main patent, which consists in that, according to the invention, the power interruption points of a pole combined into groups and the groups impedances Voltage distribution to the interruption points are connected in parallel.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt. Die Leistungsschaltstelle eines Pols eines Druckgasschalters ist aus einer Mehrzahl von druckgasbetätigte und mit Druckgas beblasene .Kontakte enthaltenden Schaltelementen a, bis a,2 gebildet, die in Form von zwei Säulen zusammengefaßt sind, welche auf Stützisolatoren b,, b2 aufgebaut sind. Mit c,, c2 sind die Messer des Trennschalters bezeichnet, der in Reihe mit der Leistungsschaltstelle liegt. Die Schaltelemente a, bis a,2 sind in Gruppen zu je zwei zusammengefaßt, und die Gruppen sind an Anzapfungen der Steuerimpedanzen d,, d2 angeschlossen, die entweder iKondensatoren oder, wie dargestellt, Ohmsche bzw. spannungsabhängige Widerstände sein können. Die Schaltelemente können auch einem Stützisolator zugeordnet sein.An exemplary embodiment of the invention is shown schematically in the drawing shown. The power switching point of a pole of a gas pressure switch is off containing a plurality of pressurized gas-actuated and pressurized gas-blown contacts Switching elements a, to a, 2 formed, which are combined in the form of two columns which are built on post insulators b ,, b2. With c ,, c2 are the knives of the disconnector, which is in series with the circuit breaker. The switching elements a, to a, 2 are combined in groups of two, and the Groups are connected to taps of the control impedances d ,, d2, which are either iCapacitors or, as shown, ohmic or voltage-dependent resistors could be. The switching elements can also be assigned to a post insulator.
