Mechanical switch contact |
| 摘要 |
The invention relates to a mechanical switch contact (10) for releasing, disconnecting, or switching over, in particular for an on-load tap changer of a step transformer, comprising at least two contact fingers or contact finger blocks (12, 14), which can each be pivoted between two end positions and which are connected to each other in an electrically conductive manner and which are each operatively connected to a rotatable switching shaft (18) by means of multi-arm joints (16), said switching shaft having all-around guide slots (24) for actuating the multi-arm joints (16) and for thereby deflecting the contact fingers or contact finger blocks (12, 14). |

1. A mechanical switch contact for releasing, separating or switching over in an on-load tap changer of a tapped transformer, which comprises at least two electrically conductively interconnected contact fingers or contact finger blocks movable independently of each other and respectively pivotable between two end positions and which are respectively operatively connected by multi-lever linkages with a rotatable switching shaft, having annular cams coupled to and serving for actuation of the multi-lever linkages and for deflection of the contact fingers or contact finger blocks. |
