摘要： There is provided a gas circuit breaker that can spray arc-extinguishing gas to arcs while preventing a spraying velocity from being reduced and can efficiently and more surely extinguish the arcs that have been generated in a scatteredly around electrodes. A gas circuit breaker 1 includes an insulation nozzle 23 that guides arc-extinguishing gas to an arc between the first arc contactor 21 and a second arc contactor 41 when a trigger electrode 31 becomes an opened state relative to a first arc contactor 21. A 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.

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： According to an embodiment, a gas-blast circuit breaker comprises a heat removal unit in a flow path of arc extinguishing gas. The heat removal unit each includes: plate-shaped heat removal members contacting the arc extinguishing gas flowing in the flow path; and a holding portion holding the plate-shaped heat removal members to stack the heat removal members at intervals in a thickness direction. Each of the heat removal members includes: an upstream side end portion; a downstream side end portion; and a thickest portion with a largest thickness which is provided between the upstream side end portion and the downstream side end portion. Thickness of the heat removal member continuously changes between the upstream side end portion and the downstream side end portion via the thickest portion.
