摘要： 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 plurality of rollable guiding elements (25) and a lever mechanism (21, 22, 23, 24) which 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 movement of the lever mechanism (21, 22, 23, 24) by means of rolling of the guiding elements (25).

摘要： A contact unit (10) for an on-load tap changer comprises a connector body (11) and a contact holder (12) coupled to each other, wherein the connector body (11) is configured to connect the contact holder (12) to a contact (2) of the on-load tap changer. The contact unit (10) further comprises a contact element (17) coupled to the contact holder (12) and configured to make electrical contact to a contact element (31) of a contact device (30) for the on-load tap changer. The contact unit (10) further comprises drive and guiding means (13, 15, 16) coupled to the contact holder (12) such that the contact element (17) is movable driven and linearly guided in a direction (T1, T2) away from the connector body (11) .
