摘要： A contact unit for an on-load tap changer comprises a connector body and a contact holder coupled to each other, wherein the connector body is configured to connect the contact holder to a contact of the on-load tap changer. The contact unit further comprises a contact element coupled to the contact holder and configured to make electrical contact to a contact element of a contact device for the on-load tap changer. The contact unit further comprises drive and guiding means coupled to the contact holder such that the contact element is movable driven and linearly guided in a direction away from the connector body.

摘要： A switching system for an on-load tap changer includes a rotatable ring stack, wherein the rotatable ring stack is part of an internal Geneva mechanism and a drive system. The ring stack includes a first current carrier ring and a second current carrier ring each of which is selectively electrically coupleable to one of a plurality of contact elements of the tap changer, and a Geneva ring. The drive system includes a driving wheel, wherein the Geneva ring is mechanically coupleable with the driving wheel, such that the Geneva ring is rotatable by the driving wheel, and the first and the second current carrier rings each are coupled with the Geneva ring such that a rotation of Geneva ring causes a joint rotation of the first and the second current carrier ring.

摘要： A system for controlling a vacuum interrupter for a power diverter switch comprises a main driving shaft which is configured to drive the control cam. The system further comprises the vacuum interrupter which is configured to separate electrical contacts in a vacuum by use of a contact rod, and a transmission unit which is configured to transmit the force generated by the main driving shaft to the contact rod. The transmission unit comprises a lever mechanism with a plurality of rollable guiding elements and a rotatable fork-shaped lever, the lever mechanism is coupled to both the control cam and the contact rod of the vacuum interrupter such that a rotation of the control cam generated by the main driving shaft causes a movement of the contact rod due to a guided rotation of the fork-shaped lever by means of rolling of the guiding elements.
