摘要： A vacuum interrupter assembly (10) for a power diverter switch comprises a vacuum interrupter (11) and a driving mechanism (12) which is coupled to the vacuum interrupter (11) and which is configured to drive opening and closing of electrical contacts of the vacuum interrupter (11). The driving mechanism (12) includes a driving rod (19) and a guiding tube (18) enclosing the driving rod (19) such that the driving rod (19) is axially movable inside the guiding tube (18) along a longitudinal axis (L) of the vacuum interrupter assembly (10). A damping unit (20) is coupled with the driving mechanism (12) and comprises a first chamber (21), a second chamber (22) and a piston (29) arranged there between with respect to the longitudinal axis (L), wherein the chambers (21, 22) are coupled with each other hydraulically and limited by the guiding tube (18) and the piston (29), and wherein the piston (29) is coupled with the driving rod (19) axially movable along the longitudinal axis (L) such that in interaction with a fluid the damping unit (20) provides hydraulic damping both when opening and when closing the electrical contacts of the vacuum interrupter (11) due to movement of the driving rod (19) and the piston (29) .

摘要： A vacuum interrupter module (1) for a tap changer comprises an insulation plate (3) having a first main side and a second main side opposite of the first main side, a vacuum interrupter assembly (10), a bypass switch assembly (8), and a control cam (13). The vacuum interrupter assembly (10) comprises a vacuum interrupter (11) and a driving mechanism (12) coupled with the vacuum interrupter (11), the vacuum interrupter (11) and the driving mechanism (12) being arranged on the first main side of the insulation plate (3). The bypass switch assembly (8) comprises two bypass contacts (4), each one mechanically connected to a corresponding bypass lever (5), the two bypass contacts (4) and the two corresponding bypass levers (5) being arranged on the first main side of the insulation plate (3). The control cam (13) is arranged on the first main side of the insulation plate (3) and configured to actuate both the driving mechanism (12) and, through the corresponding bypass levers (5), the two bypass contacts (4).
The vacuum interrupter module (1) may be used in a power diverter switch and tap changer.
