Abstract

A vacuum-type circuit interrupter is provided having lightweight separable butt arc-initiating contacts, and a pair of stationary generally cylindrical elongated arcing electrodes disposed in spaced relationship, and extending longitudinally of the vacuum circuit interrupter. During opening operation, the lightweight separable arc-initiating contacts are separated to establish arcing therebetween, and the arc is moved, or transferred radially outwardly, to space the relatively small gap between the concentrically arranged stationary cylindrical arcing electrodes, where arc extinction occurs. In certain arrangements, the arcing electrodes are concentric tubes. In other arrangements, the stationary electrodes assume a different configuration, either having a solid generally star-shaped configuration, or a hollow tubular configuration having helical slots, or other configured vent openings therethrough. In the latter case, an external shielding structure may be provided to protect the inner walls of the outer ceramic envelope.
