Unterhalb des Schaltschlittens 18 befindet sich eine Anschlusseinheit 20 mit Zugangskontakten 23a bis 23c und Abgangskontakten 24a, 24b, 24c. Diese Zugangs- und Abgangskontakte des Lasttrennschalters können natürlich auch vertauscht sein, je nach Anwendungszweck und Konzipierung gegenüber dem Stromsammelschienensystem. Weiterhin kann die Anschlusseinheit 22 mittels eines in
Die Kontakte 10a, 10b, 11a, 11b und 12a, 12b bilden eine Aufnahmekontakteinrichtung 26 und sind in einer entsprechenden plattenförmigen Einheit fest vorgesehen und seitlich gegeneinander durch nicht weiter dargestellte bzw. nicht weiter bezeichnete Trennwände isoliert, wie dies an sich bekannt ist.The
Der Lasttrennschalter besteht somit aus einem am Gehäuse 1 verschwenkbar angeordneten Deckel 2, unter welchem die Sicherungselemente 3, 4, 5 angeordnet werden, der Aufnahmekontakteinrichtung 26, welche die Kontaktpaare 10a, 10b usw. enthält, in welche die Kontakte der Sicherungselemente 3, 4, 5 eingeschoben werden, dem Schaltschlitten 18 mit Kontaktpaaren 14a, 14b, 15a, 15b, 16a, 16b und der Anschlusseinheit 22 mit den Zugangs- und Abgangskontakten 23a bis 24c. Die Anschlusseinheit 22 ist weiterhin mit Leiterbahnen versehen, die zwischen dem jeweiligen Zugangs- und Abgangskontakt unterbrochen ist und im Bereich der Leiterbahnenunterbrechung jeweils ein Kontaktpaar 28a, 28b aufweist. Für jeden Pol ist ein derartiges Kontaktpaar vorgesehen und dient dazu, durch die Kontaktpaare 14a, 14b usw. des Schaltschlittens kontaktiert zu werden. Auf diese Weise wird zwischen den Kontakten 23a, 23b, 23c im eingeschalteten Zustand des Lasttrennschalters ein Stromweg erzeugt zu den Kontakten 10a, 11a, 12a und den entsprechenden Kontakten der Sicherungselemente 3, 4, 5 und von dort über die Kontakte 10b, 11b, 12b und die Kontaktpaare 14b, 15b, 16b sowie 28b zu den Abgangskontakten 24a, 24b, 24c, wie das für den Fachmann ersichtlich ist.The switch-disconnector thus consists of a
Durch Betätigung des Sprungschaltwerks wird der Schaltschlitten 18 bedienerunabhängig bewegt, derart, dass die Kontaktpaare 14a, 14b bzw. 15a, 15b und 16a, 16b in bzw. außer Kontakt mit den oberhalb und unterhalb befindlichen Gegenkontakten gelangen. Stehen die Kontaktelemente des Schaltschlittens 18 außer Kontakt mit den Kontakten der darüber und darunter befindlichen Einheit 26 bzw. 22, ist der Lasttrennschalter spannungsfrei. In dem spannungsfreien Zustand, d.h. im Ausschaltzustand, nimmt der Hebel 7 die in
Aus vorstehender Beschreibung ist ersichtlich, dass der Deckel 2 um eine Schwenkachse verschwenkbar ist, die senkrecht steht zur Gehäuseachse des Lasttrennschalters. Der Betätigungshebel 7 ist zusammen mit dem Deckel 2 um die gleiche Schwenkachse verschwenkbar und dient dabei als Griff zum Verschwenken des Deckels 2. Im Einschaltzustand, in welchem der Deckel 2 geschlossen ist und durch eine nicht weiter dargestellte Verriegelungseinrichtung gegenüber dem Gehäuse verriegelt ist, lässt sich der Betätigungshebel 7 um eine weitere Schwenkachse verschwenken, die parallel zur Schwenkachse des Deckels 2 liegt, gegenüber dieser aber versetzt ist. Durch Betätigung des Betätigungshebels 7, der das Sprungschaltwerk aktiviert, wird der Schaltschlitten 18 bedienerunabhängig in eine Position verbracht, in welcher der Stromweg von den Eingangsanschlüssen 23a, 23b, 23c über die Sicherungselemente 3, 4, 5 zu den Abgangskontakten 24a, 24b, 24c hergestellt ist. Bedienerunabhängig bedeutet, dass die Kontaktierung bzw. Stromwegherstellung bzw. das Öffnen der Kontakte bzw. Stromwegunterbrechung mittels dem Sprungschaltwerk erfolgt und unabhängig von der Art der Betätigung des Hebels 7 durch die Bedienungsperson erfolgt.From the above description it can be seen that the
