摘要： PROBLEM TO BE SOLVED: To provide a puffer type gas circuit breaker capable of preventing an inner diameter of a nozzle throat part from being enlarged at the time of blocking of short circuit current, generating high spray pressure and stably performing high current blocking performance. SOLUTION: The puffer type gas circuit breaker includes a gas-stream-forming means to extinguish arc generated between arcing contactors arranged in opposition. The gas-stream-forming means is structured by an pressure accumulation means and an insulation nozzle to induce gas flow from the pressure accumulation means to the arc. The insulation nozzle includes a throat part to narrow down the gas flow and an upstream part to connect from the throat part to the pressure accumulation means. A member formed of a material with larger black color density index than the throat part is provided in a space pinched between the pressure accumulation means and the throat part.
