Abstract

Eine Lichtbogenlöscheinrichtung (1) für ein in Luft schaltendes Niederspannungs-Schaltgerät enthält zwischen parallelen Isolierwänden (2, 3) angeordnete und daran befestigte Löschbleche (4) sowie einen Deckel (8). Bei Bedarf kann in den Raum zwischen den Löschblechen (4) und dem Deckel (8) eine gesonderte Kühleinrichtung (10) eingebracht werden, die als Einsatzkassette ausgebildet ist und Entionisierungsmittel (27) für Schaltgase enthält. Befestigungszapfen (19, 20, 21, 22) an der Kühleinrichtung (10) und entsprechende Aufnahmeöffnungen (15, 16, 17, 18) an der Innenseite des Deckels (8) ermöglichen eine einfache Anbringung der Kühleinrichtung an dem Deckel (8), bevor dieser mit den Isolierwänden (2, 3) in Eingriff gebracht wird.

Figure 00000001
An arc quenching device (1) for an air-switching low-voltage switching device contains between parallel insulating walls (2, 3) arranged and attached thereto quenching plates (4) and a cover (8). If required, a separate cooling device (10) can be introduced into the space between the quenching plates (4) and the cover (8), which is designed as an insert cassette and contains deionizing means (27) for switching gases. Fastening pins (19, 20, 21, 22) on the cooling device (10) and corresponding receiving openings (15, 16, 17, 18) on the inside of the lid (8) allow easy attachment of the cooling device to the cover (8) before this is brought into engagement with the insulating walls (2, 3).
