Abstract: The movable nozzle (95) of a puffer circuit interrupter (15-17) has a coaxial cylindrical shield (110) connected to its downstream end and the main movable contacts (89) connected to its upstream end. The shield (110) is electrically connected to the stationary contact terminal (44). The movable contact ring (89) and coaxial shield (110) at the upstream end of the nozzle (95) define a well shielded open gap when the interrupter gap opens.

Abstract: A steel plate (130) of area greater than the area of the output of a nozzle (95) in a puffer gas interrupter (15-17) is fixed to but is spaced from the downstream end of the nozzle (95) and causes turbulence in the hot interrupter gases flowing through the nozzle (95) to improve mixing with cooler downstream gas.
