Description

Ölschalter mit Vorstufenwiderstand. In dem Patent 377 755 ist eine Anordnung beschrieben, bei der der Vorstufenwiderstand nur während des Schaltvorganges an Spannung gelegt wird, in der Aus- und Einschaltstellung des Schalters aber spannungslos ist. Es kann unter Umständen besonders bei sehr hohen Spannungen unangenehm sein, daß die mit den Enden des Widerstandes verbundenen Kontakte auf der die Schaltmesser tragenden Schalttraverse befestigt sind, daß sie also von spannungsführenden Teilen nur durch einen verhältnismäßig kurzen Kriechweg getrennt sind.Oil switch with pre-stage resistor. In the patent 377 755 an arrangement is described in which the pre-stage resistor is only connected to voltage during the switching process, but is de-energized in the off and on position of the switch. Under certain circumstances, especially at very high voltages, it can be uncomfortable that the contacts connected to the ends of the resistor are attached to the switching cross member carrying the switch blades, so that they are only separated from live parts by a relatively short creepage distance.

Erfindungsgemäß werden diese Kontakte von der Traverse entfernt und auf besonderen Stützisolatoren befestigt, während auf den Traversen an ihrer Stelle Kontaktstücke angeordnet werden, die während des Schaltvorganges die Verbindung zwischen den obenerwähnten Kontakten und den an den Durchführungsisolatoren befestigten Gegenkontakten herstellen. Auf diese Weise befindet sich zwischen dem Widerstand und den spannungsführenden Teilen überall eine freie Ölstrecke, wodurch die Betriebssicherheit bedeutend erhöht wird.According to the invention, these contacts are removed from the traverse and fixed on special post insulators while on the trusses in their place Contact pieces are arranged, the connection during the switching process between the aforementioned contacts and those attached to the bushing insulators Establish mating contacts. This way it sits between the resistance and the live parts have a free oil path everywhere, which increases operational reliability is increased significantly.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, und zwar in Abb. i in der Ansicht, in Abb. 2 in der Aufsickt. Die Durchführungsisolatoren a tragen die Schaltkontakte b und je einen weiteren Kontakt c, .der beim Schalten mit- dem Vorstufenwriderständ d verbunden wird. Die Schalttraverse wird durch die Rohree aus Isoliermaterial gebildet. Sie trägt außer dem Schaltmesser f von diesem isolierte Kontaktstücke g. Die Enden .des Widerstandes sind zu den an dem Schalterdeckel befestigten Stützen h geführt, die die Kontakte i tragen.In the drawing, an embodiment of the invention is shown, in Fig. I in the view, in Fig. 2 in the bulge. The bushing insulators a carry the switching contacts b and one further contact c each, which is connected to the pre-stage resistor d when switching. The switching traverse is formed by the pipe made of insulating material. In addition to the switch blade f, it carries contacts g insulated from it. The ends of the resistor are led to the supports h which are attached to the switch cover and which carry the contacts i.

Bei der Bewegung der Traverse gleiten die Kontaktstücke g an den Kontakten c und i entlang und stellen dadurch über den Widerstand d eine Verbindung der in den Dui chführungen enthaltenen Zu- und Ableitung her.When the traverse moves, the contact pieces g slide on the contacts c and i and thereby establish a connection of the in the inlet and outlet contained in the ducts.
