ABSTRACT:
A puffer type gas interrupter has an extra movable conducting cylinder mounted concentrically around and in fixed electrical contact with the puffer cylinder which functions to blow out the arcs produced at the moment of interruption. This conducting cylinder forms an electrical connection between stationary side finger contacts and movable side finger contacts at times of normal operation when the interrupter is in the closed state, and since, unlike the puffer cylinder, its dimensions are not constricted by the need to consider the arc blowing performance, its thickness and diameter may easily be appropriately selected to provide a current carrying area suitable for the carrying of a large main circuit current.
