Claims (3)
- Elektromagnetisches Antriebselement für einen Niederspannungs-Leistungsschalter, dasein elektromagnetisches System (7) mit einem, von einer Erregerspule umgebenen Kern (10) und zwei parallelen Schenkeln (11, 12) zur Führung des magnetischen Flusses, die jeweils erste Enden (13, 15) sowie gegenüberliegende zweite Enden (14, 16) aufweisen,einen Magnetanker (8), der um ein Gelenk (21) schwenkbar gelagert ist, um eine Ruhestellung, in der er von den genannten ersten Enden der beiden Schenkel zurückgezogen ist, sowie eine aktive Stellung einnehmen zu können, in der er magnetisch angezogen wird, bis er in Anschlag gegen die genannten ersten Enden der beiden Schenkel gelangt,einen feststehenden Kontakt (3), der innerhalb oder in der Nähe eines zwischen den genannten zweiten Enden (14, 16) der beiden Schenkel (11, 12) ausgebildeten Luftspalts angeordnet ist,einen beweglichen Kontaktträgerarm (5), der schwenkbar um ein Gelenk (22) gelagert ist, um innerhalb des Luftspalts verschoben werden zu können und dabei den mit ihm verbundenen beweglichen Kontakt (4) zwischen der genannten Ruhestellung, in der der bewegliche Kontakt (4) und der feststehende Kontakt (3) miteinander in Berührung stehen, und der genannten aktiven Stellung zu verschieben, in welcher der bewegliche Kontakt vom feststehenden Kontakt zurückgezogen ist,und einen Schlagbolzen (9) umfaßt, der als zwischen dem Magnetanker (8) und dem beweglichen Kontaktträgerarm (5) angeordnetes längliches Teil ausgebildet ist,
- Elektromagnetisches Antriebselement eines Niederspannungs-Leistungsschalters nach Anspruch 1, dadurch gekennzeichnet, daß der Schlagbolzen (9) so angeordnet ist, daß seine Längsachse in einem Winkel von 90° ± 30° zur Längsachse des Magnetankers (8) und ebenfalls in einem Winkel von 90° ± 30° zur Längsachse des beweglichen Kontaktarms (5) verläuft.
- Antriebselement nach Anspruch 3, dadurch gekennzeichnet, daß die Drehachsen des Magnetankers (8) und des beweglichen Kontaktarms (5) annähernd in der gleichen Senkrechte zu ihrer jeweiligen Ebene liegen.
