Abstract

A system (1) for controlling a vacuum interrupter (30) for a power diverter switch comprises a main driving shaft (10) which is configured to drive the control cam (13). The system (1) further comprises the vacuum interrupter (30) which is configured to separate electrical contacts in a vacuum by use of a contact rod (31), and a transmission unit (20) which is configured to transmit the force generated by the main driving shaft (10) to the contact rod (31). The transmission unit (20) comprises a lever mechanism with a plurality of rollable guiding elements (25, 26) and a rotatable forkshaped lever (22), the lever mechanism is coupled to both the control cam (13) and the contact rod (31) of the vacuum interrupter (30) such that a rotation of the control cam (13) generated by the main driving shaft (10) causes a movement of the contact rod (31) due to a guided rotation of the forkshaped lever (22) by means of rolling of the guiding elements (25, 26).
