Abstract (en)
[origin: WO2019063271A1] The invention relates to an assembly (1) and to a method for damping contact bounce in high-voltage circuit breakers, having a vacuum interrupter (18) and a holder (10) for the vacuum interrupter (18), the vacuum interrupter (18) comprising a housing (2), at least one movable contact piece (3) and at least one fixed contact piece (4). At least one mass body (12) is mechanically connected to the at least one fixed contact piece (4) in order to effect damping of the contact bounce between the at least one fixed contact piece (4) and the at least one movable contact piece (3) during a switch-on operation of the high-voltage circuit breaker.
