VACUUM INTERRUPTER WITH DOUBLE COAXIAL CONTACT ARRANGEMENT AT EACH SIDE

摘要

A vacuum interrupter is provided with a double co-axial contact arrangement in which an inner contact can have a TMF-like or Pin shape arranged within a concentrically cup shaped AMF coil having a single layer or multilayered contact parts at each side, on the side of a fixed contact arrangement as well as on the side of a movable contact arrangement. To provide high conductivity and low resistance, the outer cup shaped contact is made from a double or multiple layer arrangement, wherein at least one layer is made from a hard steel or steel alloy, and at least a second layer is made from material with high thermal conductivity.
