    • 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.

    • An electrode assembly for a vacuum interrupter is configured such that supporting members can support most of a contact electrode plate and a supporting electrode plate in an axial direction with coil conductors interposed therebetween. Accordingly, an impact generated between electrode assemblies upon a closing operation of the vacuum interrupter may be evenly distributed onto the supporting members, which may result in preventing each of the electrode plates and the coil conductors from being deformed. Also, the supporting members are inserted into the electrode plates and the coil conductors, thereby effectively preventing a current from flowing via the supporting members. In addition, the supporting member may be wide and large so as to simplify an assembly operation and reduce an assembly time.
    • 用于真空断路器的电极组件被构造成使得支撑构件能够沿着轴向方向支撑接触电极板和支撑电极板的大部分,线圈导体插入其间。 因此,在真空断路器的闭合动作时,在电极组件之间产生的冲击可以均匀分布在支撑部件上,这可能导致电极板和线圈导体中的每一个都不会变形。 此外,支撑构件被插入到电极板和线圈导体中,从而有效地防止电流经由支撑构件流动。 此外,支撑构件可以宽且大,以便简化组装操作并减少组装时间。
