Abstract:
A vacuum interrupter for a circuit breaker arrangement including a cylindrically shaped insulating part, within which a pair of electrical contact parts are coaxially arranged and concentrically surrounded by the insulating part, wherein the electrical contact parts are arranged for initiating a disconnection arc only between corresponding inner contact elements after starting a disconnection process, and corresponding outer contact elements are arranged for commutating the arc from the inner contact elements to the outer contact elements until the disconnection process is completed wherein each inner electrical contact element is a TMF-like contact element for generating mainly a transverse magnetic field, and each outer electrical contact element is an AMF-like contact element for generating an axial magnetic field.
