Abstract

When the butt contacts of a vacuum arc discharge device are parted, at least one of the contacts is withdrawn into a high dielectric strength shield, giving the device high current interruption capability. The shield may be grounded to an endwall of the device or electrically isolated therefrom. Facing the stationary contact with a hardened steel enables it to withstand the dielectric stress extant at recovery. Facing the moving contact with a refractory material allows high current and voltage interruption capability without adversely affecting current chopping performance, while limiting contact erosion and weld forces.
