Claims

[Scope of utility model registration request]

In addition to introducing a pair of electrode rods into a vacuum container so that they can approach and separate from each other, a disk-shaped electrode made of a material with high mechanical strength and low conductivity is attached to the inner end of each electrode rod. A resistive spacer is interposed to mechanically connect each electrode and the electrode rod to the back of the electrode, and the current flowing through the electrode rod is changed to a loop current centered around the electrode rod. In a vacuum interrupter that is electrically connected by a shunt type coil that generates a directional magnetic field, a circular mounting base, a plurality of arms extending radially from the mounting base, and an end of each arm are provided on the back surface of each of the electrodes. A plate-shaped adapter consisting of an end member of one arm that is adjacent to each other with the center of curvature at the base, and a circular arc portion curved in an arc shape to the near side are coaxially joined, and each of the adapters and the coil are connected in the axial direction. It is electrically connected to generate a magnetic field of the same polarity as the coil through the connecting fittings, and a radial connection is made between the end of each arm of the adapter and the end of the arc section in the periphery of each electrode. A vacuum interrupter characterized by having a notch.
