摘要： A gas circuit breaker 1 includes an insulation nozzle 23 that guides arc-extinguishing gas to an arc between a first arc contactor 21 and a second arc contactor 41 when a trigger electrode 31 becomes an opened state relative to the first arc contactor 21. The second arc contactor 41 has an opening 41a for spraying the arc-extinguishing gas, and the opening 41a is closed by the trigger electrode 31 in the first half of a current breaking action, and is opened by separation of the trigger electrode in the latter half of the current breaking action. An opening area of a first exhaust port 41b formed between the second arc contactor 41 and the insulation nozzle 23 for exhausting the arc-extinguishing gas is 0.2 times or more and two times or less of an opening area of the opening 41a of the second arc contactor 41.

摘要： A gas circuit breaker of an embodiment includes a sealed container, a first contact part and a second contact part, an operation mechanism, an insulating nozzle, a pressure accumulator, and an electric field shield. The insulating nozzle is displaced in conjunction with the first contact part in a separation process of the first contact part and the second contact part. The insulating nozzle surrounds arc discharge generated between the first contact part and the second contact part. The electric field shield is attached to the insulating nozzle. The electric field shield has a floating potential during a period of at least part of the separation process. The electric field shield is electrically connected to the second contact part such that the electric field shield has the same potential in a completely open electrode state in which separation between the first contact part and the second contact part is terminated.

摘要： A pair of fixed arc electrodes are arranged facing each other within a sealed container that is filled with arc-extinguishing gas 1. There are provided: a compression puffer chamber for accumulating pressurized gas that is obtained by elevating the pressure of the arc-extinguishing gas; and an insulated nozzle that directs the pressurized gas towards the arc discharge from the compression puffer chamber. A buffer chamber is provided, in which hot exhaust gas generated by the heat of the arc discharge is temporarily accumulated. A pressurized gas through-flow space is provided, communicating with the compression puffer chamber. In the pressurized gas through-flow space, an opening/closing section prevents inflow of hot exhaust gas by assuming a closed condition during the earlier half of the current interruption period, and in the latter half of the current interruption period the opening/closing section 41 is opened to allow flow of pressurized gas.

摘要： The gas circuit breaker includes a sealed container filled with an arc-extinguishing gas, a pair of fixed arc electrodes arranged in the sealed container to be opposite to each other, a trigger electrode movably arranged between the fixed arc electrodes and generating an arc discharge according to movement, a pressurization chamber pressuring and increasing a pressure of the arc-extinguishing gas with pressurization means, and a pressure accumulation chamber in communication with the pressurization chamber and accumulating the pressurized arc-extinguishing gas. The trigger electrode switches the pressure accumulation chamber into a closed state or an open state. The pressure accumulation chamber is switched to the closed state in a first half of breaking of the electric current, and the pressure accumulation chamber is switched to the open state in a latter half of breaking of the electric current. The arc-extinguishing gas in the pressure accumulation chamber is guided to the arc discharge.

摘要： A gas circuit breaker to reduce deterioration of insulation and current-breaking performance thereof includes a sealed container (8) filled with arc-extinguishing gas. A first fixed contactor portion (2) and a second fixed contactor portion (4) are fixed to the sealed container (8). A movable contactor portion (3) moves between the first fixed contactor portion (2) and the second fixed contactor portion (4) and conducts and breaks current between the first fixed contactor portion (2) and the second fixed contactor portion (4). An arc is generated between a fixed arc contactor (21) provided to the first fixed contactor portion (2) and a movable arc contactor (31) provided to the movable contactor portion (3) when current breaking action is extinguished by an arc-extinguishing gas being sprayed thereto. Unnecessary gas generated from the arc-extinguishing gas sprayed to the arc is accumulated in a gas chamber (5).
