Abstract

Die Erfindung bezieht sich auf einen Schalterpol für Lei­ stungsschalter, der mit einer Vakuumschaltkammer ausgerü­ stet ist. Sie geht von einer Anordnung aus, wo die Vakuum­ schaltkammer in einem Isoliergehäuse angeordnet ist. In sel­ bigen sind wenigstens zwei Steuerelektroden vorgesehen, die die Vakuumschaltkammer umfassen und die gleichzeitig an das Potential des jeweils nächstliegenden Anschlusses der Vakuum­ schaltkammer angelenkt sind. Es kommt darauf an, durch Poten­ tialverteilung einerseits Teilentladungen sicher zu vermeiden und die dielektrische Beanspruchung im Isolierstoff des Iso­ liergehäuses in Grenzen zu halten; andererseits soll das Schaltvermögen der Schaltkammer nicht ungünstig beeinflußt werden. Die Erfindung lehrt, den Metallschirm der Vakuum­ schaltkammer und/oder eine dritte Steuerelektrode durch die Gestaltung der beiden Steuerelektroden so zu beeinflussen, daß sie im geschlossenen Zustand des Schalters volles Poten­ tial und im geöffneten Zustand desselben etwa halbes Poten­ tial annehmen. Die Anordnung ist auch für die Fälle geeignet, wo die äußere Oberfläche des Isoliergehäuses keinen Erdbelag aufweist bzw. wo mehrere Schalterpole in einem Gefäß unterge­ bracht sind, das mit einem Isoliergas, z. B. SF₆, gefüllt ist. The invention relates to a switch pole for Lei Control switch equipped with a vacuum interrupter is steady. It assumes an arrangement where the vacuum switching chamber is arranged in an insulating housing. In sel bigen at least two control electrodes are provided, the include the vacuum interrupter and at the same time to the Potential of the closest connection to the vacuum control chamber are articulated. It depends on pots tial distribution on the one hand to safely avoid partial discharges and the dielectric stress in the insulating material of the Iso to limit the housing; on the other hand, that should Switching capacity of the switching chamber is not adversely affected will. The invention teaches the metal screen of vacuum switching chamber and / or a third control electrode through the To influence the design of the two control electrodes that they are full of pots when the switch is closed tial and in the open state of the same about half a pot tial accept. The arrangement is also suitable for the cases where the outer surface of the insulating housing has no earth covering has or where several switch poles in a vessel are brought up with an insulating gas, e.g. B. SF₆, is filled.
