Abstract: An exemplary 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 surrounded concentrically by the insulating part. The electrical contact parts can be configured to initiate a disconnection arc only between corresponding inner contact elements after starting a disconnection process, and corresponding outer contact elements can be configured to commutate 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 designed as a TMF-like contact element for generating mainly a transverse magnetic field, and each outer electrical contact element is designed as an AMF-like contact element for generating mainly an axial magnetic field.

Abstract: An AMF contact for a vacuum interrupter includes concentric opposing contact pieces. The contact pieces include an external electrode shaped like a coil with a plate as a bottom plate of the external electrode, which generates a strong axial magnetic field, and an inner internal electrode as a top electrode carrying the nominal current. To enable the outer electrode to generate the axial magnetic field as requested for an application, a rod is arranged between the top electrode and the bottom plate. A first end of the rod is fixed at a lower side of the top electrode, and a second end of the rod is guided through an opening of the bottom plate. The second end of the rod has an extended head which locks or tightens the rod in a defined axial position. The disclosed embodiments are applicable for standard AMF or TMF (cup) contacts to reinforce them.
