Abstract
An assembly and a method for damping contact bounce in high-voltage circuit breakers include a vacuum interrupter and a holder for the vacuum interrupter. The vacuum interrupter includes a housing, at least one movable contact piece and at least one fixed contact piece. At least one mass body is mechanically connected to the at least one fixed contact piece in order to effect damping of the contact bounce between the at least one fixed contact piece and the at least one movable contact piece during a switch-on operation of the high-voltage circuit breaker.

An assembly for a high-voltage circuit breaker, the assembly comprising:
- a vacuum interrupter including a housing, at least one movable contact piece and at least one fixed contact piece;
- a holder for said vacuum interrupter;
- and
- at least one mass body mechanically connected to said at least one fixed contact piece to effect damping of contact bounce between said at least one fixed contact piece and said at least one movable contact piece during a switch-on operation of the high-voltage circuit breaker.
A method for damping contact bounce in high-voltage circuit breakers, the method comprising the following steps:
- providing an assembly including a vacuum interrupter having a housing, at least one movable contact piece and at least one fixed contact piece, and at least one mass body mechanically connected to the at least one fixed contact piece;
- moving the at least one movable contact piece when switching on the vacuum interrupter, causing the at least one movable contact piece to strike the at least one fixed contact piece with a pulse;
- and
- transmitting the pulse to the at least one mass body, causing a contact bounce to be partially or completely damped.
