摘要： A contact assembly and a vacuum circuit breaker for interrupting an electrical current are disclosed. The contact assembly includes an outer field generating element for generating a first axial magnetic field (AMF), and an inner field generating element for generating a second AMF opposite to the first AMF. The inner field generating element can be coaxial with the outer field generating element and can have a smaller diameter than the outer field generating element. The outer field generating element can be cup-shaped and slotted with non-radial slots to generate the first AMF. The contact assembly can include an innermost conducting element for nominal current conduction and coaxially adjusted with the inner field generating element.

摘要： A shielding element is disclosed for use in medium voltage switchgears with vacuum interrupters with at least two contacts, which are movable along a switching path between closed and open contact positions, wherein the shielding element is positioned around the contact position region in the vacuum interrupter, wherein at least the inner surface of the shielding is applied with an implemented surface structure to form a topographic structure which is a rough or a structured surface. To enhance the energy absorbance behavior of the shielding, the implemented topographic structure can be formed such that by given constant or approximately constant volume (Vi) of the shielding body, the surface ratio of the treated surface (S2) with implemented surface structure and volume V2, and a untreated surface (S1) without topographic structure and volume V1 is greater than 1, so that this follows the condition: V1˜V2 and S2/S1>1.

摘要： 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.
