ABSTRACT:
A vacuum interrupter for reducing contact resistance and thereby reducing electromagnetic repulsive force between electrodes, is obtained. The vacuum interrupter includes a stationary electrode rod fixedly placed on one closed end of a cylindrical evacuated envelope closed at both ends thereof; a movable electrode rod movably placed on the other closed end; disc shaped contacts placed on opposing ends of the electrode rods; and reinforcement members for reinforcing the contact placed between each electrode rod and the associated contact. In such a configuration, a coefficient of linear expansion of the reinforcement member differs from that of the contact, and the reinforcement member and the associated contact are jointed by soldering at a plurality of opposing parts thereof.
