器。[Claims for Utility Model Registration] A fixed contact, a movable contact that approaches and separates from the fixed contact, and is excited by an arc current generated when the movable contact separates from the fixed contact to generate magnetic flux for driving arc rotation. an arc drive coil arranged at an end of the arc drive coil, an arc rotating plate disposed at an end of the arc drive coil, and a boosting chamber housing the fixed contact, the arc drive coil, and the arc rotating plate, the movable contact side of the boosting chamber A gas circuit breaker is provided with a nozzle protruding toward the arc rotating plate at an end thereof, and the movable contact approaches and separates from the fixed contact through the inside of the nozzle, the annular boss having a hole through which the movable contact passes. and a propeller-shaped blade projecting radially outward from the outer periphery of the boss portion, the gas guide member is disposed in the space between the nozzle and the arc rotary plate in the pressurization chamber, and the gas guide The first between the member and the arc rotating plate
the gas guide so as to direct a gas flow generated radially outward in the gas space as the arc rotates to the second gas space between the gas guide member and the nozzle; The shape of the wing of the member is set, and the annular space between the boss part of the gas guiding member and the nozzle defines a nozzle part that generates a gas flow from within the second gas space toward the inside of the nozzle. A gas circuit breaker characterized in that the cross-sectional shape of the boss portion of the gas guide member is set so as to configure the gas guide member.
