Definitions

  • a primary object of the invention is to limit the heating of the electrodes during ordinary operation of the device, the contacts being closed, despite the confinement for which the cover is responsible.
  • the collars are for this purpose provided with continuous partitions extending projecting in the radial direction, which separate the openings from the neighboring volumes where the hot gases are released and which thus house the openings: the volume surrounding the cover is almost not invaded by hot gases, which therefore have no possibility of crossing it.
  • the invention can be improved in several other aspects. If the collars each include a support ring on the contact carriers and an interior portion supporting the main portion of the cover, the continuous partitions being joined to the support rings and the openings extending between the continuous partitions and the interior portions , a front sleeve can be joined to the continuous partition, surrounding the inner portion, the openings then also extending between the inner portion and the front sleeve: the front sleeve contributes to sheltering the openings even better, while favoring the hold equipment dielectric.
  • the interior portions of the collars may also carry a field electrode, the field electrodes surrounding the contact electrodes and the openings also extending between the contact electrodes and the field electrodes.
  • the openings extend to an angular portion of one of the collars and to an angular portion opposite to the previous one of the other of the collars.
  • the openings (47) of one of the collars (31) are located at the top, and the openings (48) of the other of the collars (32) are located at the bottom, or more generally the openings of the collars are placed only at opposite angular sectors on the circumferences of the collars (31 and 32), which imposes a diagonal path for the ventilation gas, passing through the middle of the interior volume (57), and guarantees good ventilation.
  • This variant can be achieved by adding plugs (61 and 62) filling the sections of the other openings between the ribs (41 and 42).

Claims (8)

  1. Unterbrecherkammergerät, umfassend zwei Kontaktelektroden (1, 2), die beweglich sind zwischen einer Schließposition und einer Öffnungsposition, zwei Kontaktträger (3, 4), die die Elektroden unterstützen, und eine Kappe (29), die die Kontaktträger verbindet und Bereiche gegenüber den Elektroden umgibt, wobei die Kappe einen dielektrischen Hauptbereich und zwei Krägen (31, 32) umfasst, welche Enden des Hauptbereichs mit den Kontaktträgern (3, 4) verbinden, wobei die Krägen mit Öffnungen (47, 48) ausgestattet sind, die eine Verbindung herstellen zwischen einem Volumen (57) innerhalb der Kappe, in dem sich die Bereiche gegenüber den Elektroden erstrecken, und einem Volumen (58) außerhalb der Kappe, das das Innenvolumen umgibt, dadurch gekennzeichnet, dass die Krägen eine durchgehende Wand (35, 36) umfassen, die über den Hauptbereich in radialer Richtung nach Außen vorsteht, und dass sich die Öffnungen durch die Krägen hindurch zwischen dem Hauptbereich (30) und den durchgehenden Wänden (35, 36) erstrecken.
  2. Gerät nach Anspruch 1, dadurch gekennzeichnet, dass die Krägen einen Ring (33, 34) zur Unterstützung an den Kontaktträgern (3, 4) und einen Innenbereich (43, 44) zur Unterstützung des Hauptbereichs umfassen, dass die durchgehenden Wände (35, 36) mit den Unterstützungsringen verbunden sind, und dass sich die Öffnungen zwischen den durchgehenden Wänden und den Innenbereichen erstrecken.
  3. Gerät nach Anspruch 2, dadurch gekennzeichnet, dass die Innenbereiche (43, 44) an den durchgehenden Wänden (35, 36) angeordnet sind, und dass sich die Öffnungen zwischen den Rippen (41, 42) erstrecken, die an den durchgehenden Wänden vorgesehen sind und an die sich die Innenbereiche abstützen.
  4. Gerät nach Anspruch 2 oder 3, dadurch gekennzeichnet, dass die Krägen eine vordere Hülse (37, 38) umfassen, die mit der durchgehenden Wand verbunden ist und den Innenbereich umgibt, wobei sich die Öffnungen auch zwischen dem Innenbereich und der vorderen Hülse erstrecken.
  5. Gerät nach Anspruch 4, dadurch gekennzeichnet, dass die vorderen Hülsen (37, 38) einen abgerundeten Wulst (55, 56) an einem freien Ende umfassen, der zum Hauptbereich (30) hin vorsteht.
  6. Gerät nach einem der Ansprüche 1 bis 5, dadurch gekennzeichnet, dass die Kontaktträger (3, 4) einen Außenrand (15, 16) umfassen, der einen Gasströmungsweg ausgehend von einem hinteren hohlen Ende der Elektroden begrenzt, wobei sich die Ränder vor den durchgehenden Wänden öffnen, und dass die Krägen (39, 40) eine hintere Hülse umfassen, die mit der durchgehenden Wand verbunden ist und ein Ende der Außenränder umgibt.
  7. Gerät nach Anspruch 2, dadurch gekennzeichnet, dass die Innenbereiche der Krägen jeweils eine Feldelektrode (45, 46) tragen, wobei die Feldelektroden die Kontaktelektroden (1, 2) umgeben, und wobei sich die Öffnungen auch zwischen den Kontaktelektroden und den Feldelektroden erstrecken.
  8. Gerät nach einem der Ansprüche 1 bis 7, dadurch gekennzeichnet, dass sich die Öffnungen zu einem Winkelbereich (31) eines der Krägen und zu einem zum Vorhergehenden entgegengesetzten Winkelbereich des anderen der Krägen (32) derart erstrecken, dass einer Gasströmung zur Ventilation durch Konvektion ein diagonaler Weg auferlegt wird, wobei der Weg durch einen zentralen Bereich des Innenvolumens (57) verläuft.
