Abstract

Der Mittelspannungslasttrennschalter hat einen Hauptkontakt (56) mit einem schwenkbar daran gelagerten Schaltmesser (60), das beim Ausschalten mit einer Flachlöschkammer (62) zusammenwirkt. Es ist eine Fangeinrichtung vorgesehen, an der das Schaltmesser (60) nach dem Herausschwenken aus der Flachlöschkammer (62) rastet. Das Schaltmesser (60) kann insbesondere in rückwärtiger Verlängerung einen Klinkenhe­ bel (14) tragen, dessen Klinke (40) mit einem ortsfesten Bügel (12) zum Eingriff kommt. Die Raststellung wird beim Einschalten aufgehoben, wobei sich die Rastelemente berüh­ rungsfrei voneinander entfernen. The medium-voltage switch-disconnector has a main contact (56) with a pivoting switch blade attached to it (60), which when switched off with a flat extinguishing chamber (62) cooperates. A safety gear is provided on the switch blade (60) after swiveling out of the Flat fire chamber (62) snaps into place. The switch blade (60) can especially in a rear extension a latch marriage bel (14) carry, its pawl (40) with a stationary Bracket (12) comes into engagement. The rest position is at Switched on canceled, with the locking elements touching remove from each other.
