Die Erfindung betrifft eine Schalteinheit nach dem Oberbegriff des Anspruches l.The invention relates to a switching unit according to the preamble of claim 1.
Bei Niederspannungs-Leistungsschalter ist es bekannt, Drehkontakte mit Doppelunterbrechung zu verwenden. Diese bestehen aus zwei feststehenden Stromschienen und einem rotierenden Schaltstück, wie in der EP 0 174 904 Bl oder der 0 314 504 Bl.It is known to use rotary contacts with double interruption in low-voltage circuit breakers. These consist of two fixed busbars and a rotating contact piece, as in EP 0 174 904 Bl or 0 314 504 Bl.
Derartige Schalteinheiten mit Schaltkontakten bestehen aus zwei Kontaktstückpaaren mit zwei feststehenden und zwei beweglichen Kontaktstücken, wobei eine wippenartig gelagerte Kontaktbrücke vorhanden ist und die Kontaktbrücke an ihren Enden mit wechselseitig angeordneten beweglichen Kontaktstücken versehen ist.Such switching units with switching contacts consist of two contact piece pairs with two fixed and two movable contact pieces, whereby a rocker-like contact bridge is present and the contact bridge is provided with alternately arranged movable contact pieces at its ends.
Mit derartigen Drehkontakten läßt sich eine kurze Öffnungszeit und eine hohe Schaltleistung realisieren.With such rotary contacts, a short opening time and high switching capacity can be achieved.
Aufgabe der Erfindung ist es, eine Schalteinheit nach dem Oberbegriff des Anspruches 1 zu schaffen, mit der es möglich ist, die Schaltleistung zu erhöhen.The object of the invention is to create a switching unit according to the preamble of claim 1, with which it is possible to increase the switching performance.
Die Aufgabe der Erfindung wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst, während in den Unteransprüchen besonders vorteilhafte Weiterbildungen der Erfindung gekennzeichnet sind.The object of the invention is achieved by the characterizing features of claim 1, while particularly advantageous developments of the invention are characterized in the subclaims.
Anhand der Zeichnung, in der ein Ausführungsbeispiel dargestellt ist, sollen die Erfindung, weitere Ausgestaltungen und Verbesserungen der Erfindung und weitere Vorteile näher beschrieben und erläutert werden.The invention, further refinements and improvements of the invention and further advantages will be described and explained in more detail with reference to the drawing, in which an embodiment is shown.

Fig. 1 eine schematische Darstellung der geschlossenen Schalteinheit.Fig. 1 is a schematic representation of the closed switching unit.
Fig. 2 eine schematische Darstellung der geöffneten Schalteinheit undFig. 2 is a schematic representation of the opened switching unit and
Die Fig. 1 zeigt die Schalteinheit mit geschlossenen Schaltkontakten. Diese besteht aus zwei Stromschienen 1, 2, die
mit den feststehenden Kontaktstücken 3,4 versehen sind und zwei beweglichen Kontakten bzw. wippenartigen Kontaktbrücken 5,6.
Zwischen den feststehenden Kontaktstücken 3,4 sind die zwei wippenartig gelagerte Kontaktbrücken 5,6 angeordnet.Fig. 1 shows the switching unit with closed switching contacts. This consists of two busbars 1, 2, which are provided with the fixed contact pieces 3, 4 and two movable contacts or rocker-like contact bridges 5, 6.
The two rocker-like contact bridges 5,6 are arranged between the fixed contact pieces 3,4.
Die Schalteinheit besteht aus drei im wesentlichen dreieck- bzw. sternförmig angeordneten Kontaktstückpaaren 12,13,14.The switching unit consists of three contact pairs 12, 13, 14 arranged essentially in a triangular or star shape.
Beide Kontaktbrücken 5,6 sind an ihren Enden mit den wechselseitig angeordneten Kontaktstücken 8,9,10,11 versehen.
Jeweils ein Kontaktstück 8,11 auf der einen Seite der
Kontaktbrücke 5 oder 6 bildet mit dem feststehen Kontaktstück 3 oder 4 ein Kontaktstückpaar 12 oder 13, während auf den anderen
Seiten der Kontaktbrücken 5, 6 die Kontaktstücke 9,10 gemeinsam ein drittes Kontaktstückpaar 14 bilden.Both contact bridges 5,6 are provided at their ends with the alternately arranged contact pieces 8,9,10,11.
One contact piece 8,11 on each side of the
Contact bridge 5 or 6 forms a contact piece pair 12 or 13 with the fixed contact piece 3 or 4, while on the other sides of the contact bridges 5, 6 the contact pieces 9, 10 together form a third contact piece pair 14.
Die Kontaktbrücken sind um die Drehpunkte 15 und 16 drehbar. Bei entsprechender Anordnung der Kontaktdruckfedern wird ein kippendes System erreicht.The contact bridges can be rotated around the pivot points 15 and 16. If the contact pressure springs are arranged accordingly, a tilting system is achieved.
Durch diese Kontaktanordnung ist keine Litze erforderlich und es wird eine schnelle Öffnungszeit und eine hohe Schaltleistung erreicht.This contact arrangement means that no stranded wire is required and a fast opening time and high switching capacity are achieved.
