Claims (6)

  1. Elektrischer Trennschalter (10) mit einer Umhüllung (12), die mit einem isolierenden Fluid gefüllt ist; mindestens einem Paar gegeneinander gerichteter Kontakte (14, 16), die in der Umhüllung untergebracht sind und die getrennt werden können, um einen Lichtbogen zu ziehen; einem Betätigungsglied (22) zum axialen Bewegen eines Kontaktes relativ zu dem anderen, wobei das Betätigungsglied einen an ihm montierten Kolben (24) hat, wodurch im Betrieb eine axiale Bewegung des Betätigungsglieds bewirkt, dass der Kolben (24) ein Spülfluid von dem Bereich, aus dem der Lichtbogen gezogen wird, komprimiert, um die Löschung des Lichtbogens zu unterstützen, dadurch gekennzeichnet, daß Mittel (26, 28) vorgesehen sind, um gesonderte axiale und radiale Strömungen des komprimierten Spülfluids in den Bereich zwischen den Kontakten zu richten, wo der Lichtbogen gezogen wird.
  2. Elektrischer Trennschalter nach Anspruch 1, dadurch gekennzeichnet, dass eine Spule (18) neben den Kontakten (14, 16) angeordnet ist, die ein Magnetfeld erzeugt, das den zwischen den Kontakten gezogenen Lichtbogen dreht.
  3. Elektrischer Trennschalter nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass das Mittel zum axialen Richten des komprimierten Spülfluids in den Bereich zwischen den Kontakten (14, 16) ein Durchtritt (26) ist, der sich durch mindestens einen der Kontakte (16) hindurch erstreckt.
  4. Elektrischer Trennschalter nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, dass das Mittel zum radialen Richten des komprimierten Spülfluids in den Bereich zwischen den Kontakten mindestens ein Kanal (28) ist.
  5. Elektrischer Trennschalter nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, dass eine Abschirmung (20) neben der Spule (18) vorgesehen ist, um zu verhindern, dass die Spule durch den Lichtbogenstrom kurzgeschlossen wird.
  6. Elektrischer Trennschalter nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, dass das Spülfluid Schwefelhexafluoridgas ist.
