Abstract:
A vacuum interrupter arrangement for a circuit breaker includes a first cylindrical shaped vacuum insert within which a pair of corresponding electrical contacts is coaxially arranged. The electrical contacts include a fixed electrical contact which is attached to the first vacuum insert and an axially movable electrical contact which is operated by a pushrod. A second cylindrical shaped vacuum insert is coaxially arranged to the first cylindrical shaped vacuum insert. Both vacuum inserts are coaxially surrounded by an outer vacuum container in order to form a double contact gap version.
