Abstract
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.
