Abstract
Bei Hörnerschaltern, die zwei zueinander V-förmig ange ordnete, als Fußpunkte für den Schaltlichtbogen vorgesehe ne Hörnerelektroden aufweisen, kann bei nicht vermeidba ren Abschaltungen unter Überlast der Schaltlichtbogen aus einem als erlaubt definierten Brennbereich austreten, auf andere benachbarte Teile übergehen und diese beschädigen. Zur Vermeidung derartiger Schäden wird bei Hörnerschal tern zur Anwendung in elektrischen Netzen mit Kurzschluß- bzw. Erdschlußabschaltung durch Leistungsschalter, an der definierten Grenze zwischen einem erlaubten und einem unerlaubten Brennbereich für den Schaltlichtbogen eine geerdete dritte Elektrode für den Schaltlichtbogen angeord net, auf die der aus dem erlaubten Brennbereich austretende Schaltlichtbogen übergeht und derart einen Erdschluß- bzw. Kurzschluß verursacht, der vom übergeordneten Leistungs schalter betriebsmäßig fortgeschaltet wird. In the case of horn switches, the two are mutually V-shaped ordered, provided as base points for the switching arc ne horn electrodes can, if not avoidable Ren shutdowns under overload of the switching arc emerge from a burning area defined as permitted ignore other neighboring parts and damage them. To avoid such damage, horn scarf ters for use in electrical networks with short-circuit or earth fault shutdown by circuit breaker on the defined boundary between an allowed and an unauthorized burning area for the switching arc grounded third electrode arranged for the switching arc net to which the one emerging from the permitted firing range Switching arc arises and such an earth fault or Short circuit caused by the parent power switch is operationally advanced.
