ABSTRACT:
A puffer interrupter with arc energy assist employs a cylinder which moves telescopically over a stationary piston. The cylinder carries a movable contact structure and an insulation nozzle and moves within an insulation chamber. The cylinder has an extending flange slidably sealed to the interior of the housing. The flange has a surface which faces the gas volume which is expanded during arc current interruption so that a force is applied to the cylinder which adds to the force of an operating mechanism connected to the cylinder in order to operate the interrupter to its open position.
