Abstract:
To provide a gas circuit breaker designed to achieve further improvement in interruption performance for a small to medium current. The gas circuit breaker according to the present invention includes: an operation mechanism  1;  a heat puffer chamber  19;  a machine puffer chamber  32;  a release valve  34;  a movable main contact  5  and movable arc contact  11;  a stationary main contact  6  and stationary arc contact  12;  a movable-side leading conductor  14;  and a stationary-side leading conductor  15,  and features: a separation cylinder  21  for radially partitioning the heat puffer chamber  19;  an inner circumferential flow path  24  formed on an inner circumferential side of the separation cylinder  21;  and a check valve  22  for opening or closing a communication hole  23.

Claim (Index 1):
A gas circuit breaker comprising:\n a cylindrical movable-side main conductor supportively fixed by an insulation cylinder disposed in a gas-filled envelope containing an insulation gas having an arc-extinguishing property, connected to a movable-side leading conductor connected to an electric power system, and including an exhaust hole for exhausting a high temperature and pressure gas as the insulation gas raised in temperature and pressure by a generated arc; a hollow exhaust shaft disposed in the movable-side main conductor and movable in an axial direction of the movable-side main conductor; an operation mechanism coupled to the exhaust shaft and outputting a force operating in an axial direction of the exhaust shaft; a cylinder coaxially coupled to the exhaust shaft and axially slidable on an inside surface of the movable-side main conductor, a piston coupled to the cylinder, an insulation nozzle coupled to the piston, and a heat puffer chamber enclosed by the cylinder; a blast-gas flow path communicating the heat puffer chamber and an arc space, and defined by a gap between the insulation nozzle and a movable element cover; a puffer piston fixed to the inside of the movable-side main conductor, and including an opening which is opened in the axial direction of the movable-side main conductor and whose inside surface allows the exhaust shaft to slide thereon; a hole communicating a movable-side conductor inner circumferential space defined on the operation mechanism side as seen from the puffer piston and a machine puffer chamber formed on the opposite side from the operation mechanism; a release valve for releasing the insulation gas from the machine puffer chamber into the movable-side conductor inner circumferential space when the machine puffer chamber is compressed by the exhaust shaft and the cylinder axially moved by the operation mechanism; a movable contact electrically connected to the movable-side leading conductor; and a contact which is electrically connected to a stationary-side leading conductor connected to the electric power system and is in contactable/separable relation with the movable contact, the gas circuit breaker featuring: a separation cylinder disposed in a manner to radially partition the heat puffer chamber; an inner circumferential flow path defined by the separation cylinder on an inner circumferential side of the heat puffer chamber; and a straightening mechanism for opening or closing a communication hole communicating the inner circumferential flow path and the machine puffer chamber.
