A vacuum interrupter comprises a pair of opposed conductor rods extending exteriorlly of a vacuum vessel, a pair of main electrodes mounted to ends of the paired conductor rods and separable from each other, and coil electrodes which induce axial magnetic flux acting on arc produced when one main electrode separates from the other main electrode. The coil electrode includes a first arm section connected to the conductor rod and passing the current coming from one portion of the conductor rod radially thereof, a branching section for branching the current from the first arm section in reverse directions, and a second arm section for passing the branched currents until they are totalized again at the other portion of the conductor rod separated from the one portion by a spacer interposed between the first and second arm sections, whereby magnetic flux induced by the branched currents is cancelled out at the conductor rod, preventing the generation of eddy current in the conductor rod.
A vacuum interrupter comprising a vacuum vessel, a pair of conductor rods extending exteriorly of the vacuum vessel, and a pair of electrode assemblies respectively connected to the conductor rods within the vacuum vessel, each of said electrode assemblies having a main electrode from which arc may be ignited, at least one of these main electrodes being electrically connected with a coil electrode for passing a current coming thereinto from an associated one of the conductor rods in such a manner that the current induces axial magnetic flux, wherein said coil electrode comprises:
