Claims (12)

  1. Vorwahleinrichtung betätigende Vorrichtung für eine Vorwahleinrichtung in einem Umsteller eines Transformators, wobei die Vorrichtung ein Ansteuerungseingabemittel (11) umfasst, das ein Rotationselement umfasst, welches dafür ausgelegt ist, einen Rotationseingabebewegungshub einer vorgegebenen Länge auszuführen, einen drehbaren Vorwahlarm (51) umfasst, der zum Ausführen eines Hubs der Vorwahleinrichtung von einem ersten Kontakt zu einem zweiten Kontakt ausgelegt ist, und einen Bewegungsübertragungsmechanismus umfasst, der mit dem Ansteuerungseingabemittel (11) und mit dem Vorwahlarm (51) verbunden ist, wobei der Bewegungsübertragungsmechanismus zum Konvertieren der Eingabebewegung derart ausgelegt ist, dass der Vorwahleinrichtungshub ein Bewegungsmuster erhält, das eine Anfangsperiode von relativ langsamer Bewegung, eine Zwischenperiode von relativ schneller Bewegung und eine Endperiode von relativ langsamer Bewegung hat, dadurch gekennzeichnet, dass der Bewegungsübertragungsmechanismus einen Antriebsarm (10) umfasst, der mit dem Rotationselement rotiert, und einen schwenkbaren Verbindungsarm (20) umfasst, der mit dem Vorwahlarm (51) verbunden ist, wobei der Antriebsarm (10) ein Widerlagermittel (12, 13) hat, das zum Einwirken auf den Verbindungsarm (20) ausgelegt ist, wobei das Widerlagermittel (12, 13) eine erste Widerlagereinheit (12) und eine zweite Widerlagereinheit (12, 13) umfasst, wobei die Widerlagereinheiten an verschiedenen radialen Positionen des Antriebsarms (10) befestigt sind, und dadurch, dass der Verbindungsarm (20) ein Nockenflächenmittel (23a, 23b, 24a, 24b) hat, das zum Zusammenwirken mit jeder der Widerlagereinheiten (12, 13) ausgelegt ist.
  2. Vorwahleinrichtung betätigende Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, dass die Anfangsperiode 5 - 20 % des Vorwahleinrichtungshubs darstellt und dass die Endperiode 5 - 20 % des Vorwahleinrichtungshubs darstellt.
  3. Vorwahleinrichtung betätigende Vorrichtung nach einem der Ansprüche 1 - 2, dadurch gekennzeichnet, dass die mittlere Geschwindigkeit des Vorwahlarms (51) während der Zwischenperiode mindestens zweimal so groß wie die mittlere Geschwindigkeit des Vorwahlarms (51) während der Anfangsperiode und der Endperiode ist.
  4. Vorwahleinrichtung betätigende Vorrichtung nach einem der Ansprüche 1 - 3, dadurch gekennzeichnet, dass jede Widerlagereinheit (12, 13) eine Rolle ist.
  5. Vorwahleinrichtung betätigende Vorrichtung nach einem der Ansprüche 1 - 4, dadurch gekennzeichnet, dass das Nockenflächenmittel (23a, 23b, 24a, 24b) dafür ausgelegt ist, in Kontakt mit der radial inneren Widerlagereinheit (12) während der Anfangsperiode zu sein und in Kontakt mit der radial äußeren Widerlagereinheit (13) während der Zwischenperiode und der Endperiode zu sein.
  6. Vorwahleinrichtung betätigende Vorrichtung nach einem der Ansprüche 1 - 4, dadurch gekennzeichnet, dass das Nockenflächenmittel (23a, 23b, 24a, 24b) ein erstes Nockenteilmittel (23a, 23b) umfasst, das zum Zusammenwirken mit der ersten Widerlagereinheit ausgelegt ist, und ein zweites Nockenteilmittel (24a, 24b) umfasst, das zum Zusammenwirken mit der zweiten Widerlagereinheit ausgelegt ist.
  7. Vorwahleinrichtung betätigende Vorrichtung nach Anspruch 6, dadurch gekennzeichnet, dass das erste Nockenteilmittel (23a, 23b) sich in einer größeren radialen Distanz von einer Schwenkachse (21) des Verbindungsarms (20) befindet als das zweite Nockenteilmittel (24a, 24b).
  8. Vorwahleinrichtung betätigende Vorrichtung nach Anspruch 6 oder 7, dadurch gekennzeichnet, dass das erste Nockenteilmittel (23a, 23b) mindestens einen Nockenabschnitt umfasst, der die Form eines konkaven Bogens hat, und dadurch, dass die radiale Ausdehnung des zweiten Nockenteilmittels (24a, 24b) mindestens zweimal so groß ist wie die radiale Ausdehnung des mindestens einen Nockenabschnitts.
  9. Vorwahleinrichtung betätigende Vorrichtung nach einem der Ansprüche 1 - 8, dadurch gekennzeichnet, dass das Ansteuerungseingabemittel (11) so ausgelegt ist, dass es in jeder Richtung zum Drehen des Vorwahlarms (51) in jeder Richtung rotieren kann.
  10. Vorwahleinrichtung betätigende Vorrichtung nach Anspruch 9, bei Abhängigkeit von Anspruch 8, dadurch gekennzeichnet, dass das zweite Nockenteilmittel (24a, 24b) eine U-Form hat, dadurch, dass das Nockenflächenmittel (23a, 23b, 24a, 24b) symmetrisch in Bezug auf eine Linie (L) ist, die die Mitte des U-förmigen zweiten Nockenteilmittels (24a, 24b) senkrecht zu einem Boden desselben schneidet, dadurch, dass das erste Nockenteilmittel (23a, 23b) zwei Nockenabschnitte umfasst, die sich auf jeder Seite des U-förmigen zweiten Nockenteilmittels (24a, 24b) befinden, wobei die Nockenabschnitte eine identische Form haben, außer, dass sie in Bezug auf einander gespiegelt sind.
  11. Umsteller, dadurch gekennzeichnet, dass der Umsteller (100) eine Vorwahleinrichtung betätigende Vorrichtung nach einem der Ansprüche 1 - 10 umfasst.
  12. Transformator, dadurch gekennzeichnet, dass der Transformator einen Umsteller nach Anspruch 11 umfasst.
