| 摘要 |
The invention relates to a vacuum interrupter with double co-axial contact arrangement in which the inner contact has a TMF-like or Pin shape arranged within concentrically cup shaped AMF coil with a single layer or multilayered contact parts at each side, th.m. on the side of the a fixed contact arrangement as well as on the side of a movable contact arrangement according to the preamble of claim 1. In order to enhance this special construction furthermore in order to result high conductivity and low resistance, the invention is, that 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. |
