摘要

PURPOSE: A puffer type gas circuit breaker is provided to discharge the high pressure and high temperature gas to the distant location from an insulation support cask and an injection conductor, thereby improving insulation performance. CONSTITUTION: A partition wall (13) has a flange part in both ends. The partition wall forms the inner space in a stationary cylinder (11). The flange part on the one side of the partition wall has a suction hole (13a) and a vent hole (13b). The flange part on the one side of the partition wall forms a machine puffer chamber (S2). The flange part on the other side of flange part forms the stationary cylinder and a hot gas exhaust chamber (S4).
