    • PROBLEM TO BE SOLVED: To provide a gas-blowing breaker, capable of obtaining a disconnecting property equal to or higher than the case of using an SF 6 gas, using alternative gas as arc-extinguishing gas. SOLUTION: A gas-blowing disconnecting part 1 and a gas-blowing disconnecting part 2 are arranged in series between bushing terminals 24, an alternative gas that is superior in a BTF disconnecting property is sealed in the disconnecting part 1 as the arc-extinguishing gas; and alternative gas that is superior in an SLF disconnecting property is sealed in the disconnecting part 2 as the arc-extinguishing gas. Since the gas-blowing part 1 and the gas- blowing part 2 are electrically connected in series, the gas-blowing breaker is obtained, which is superior in both the SLF disconnecting property and the BTF disconnecting property and has the disconnecting property equal to or higher than the case using the SF 6 gas. The use of the alternative gas largely contributes to the prevention of global warming. COPYRIGHT: (C)2004,JPO

    • PROBLEM TO BE SOLVED: To provide a current breaking method of a puffer type gas-blast circuit breaker miniaturizable, reducible in operation force and of stably sustainable in puffing pressure, and to provide the puffer type gas-blast circuit breaker. SOLUTION: This puffer type gas-blast circuit breaker is so structured that a piston 6 is connected to a center shaft 5a through a link mechanism 18; both a puffer cylinder 5 and the piston 6 are driven in a breaking direction in the initial stage of a breaking operation by the link mechanism 18 while keeping a nearly constant facing distance; even if a pressure rise in a compression chamber 9 occurs by an arc generated accompanied by separation between a fixed arc contact 1 and a movable arc contact 2, the rise is prevented from causing an operation reaction force to an operation unit; the piston 6 is brought into a nearly fixed state by the link mechanism 18 in the ending stage of the breaking operation in which the fixed arc contact 1 exits a throat 3a of an insulation nozzle 3; and an arc-suppressing gas in the compression chamber 9 is compressed by the puffer cylinder 5.

    • 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.
