    • A puffer type gas circuit breaker comprises a first and a second arcing electrodes movable relative to each other, an insulating nozzle surrounding the second arcing electrode, a puffer device for introducing an arc-suppressing gas into the insulating nozzle to puff out the arc produced between the two arcing electrodes when the breaker is in motion for circuit breaking, and a movable shield device for relieving the concentration of an electric field at the front end of the first arcing electrode during the breaker motion for circuit breaking. When the breaker is closed and the circuit made, the movable shield device surrounds the first arcing electrode and insulating nozzle, with a predetermined gap between itself and the insulating nozzle opposite thereto, and is kept at the same potential as the first arcing electrode. The circuit breaker further includes a device for maintaining the predetermined gap and the same potential at least in the early stage of the breaker motion for current breaking.

    • A puffer type gas-blast circuit breaker includes at least one interrupting unit mounted in a vessel filled with an arc-extinguishing gas of a unitary pressure. The interrupting unit comprises: a fixed contact; a movable contact movable toward and away from the fixed contact to be engaged with and to be disengaged from the fixed contact respectively, the movable contact having an axial hollow portion, wherein an arc is established between the contacts upon disengagement of the movable contact from the fixed contact; an insulating nozzle encompassing a free end portion of the movable contact and having a throat portion therein, which is substantially closed with the fixed contact; a compression chamber filled with an arc extinguishing gas; a suction chamber, wherein an arc extinguishing gas within the compression chamber is compressed and the volume of the suction chamber is enlarged upon movement of the movable contact away from the fixed contact, whereby a pressure difference between the compression chamber and the suction chamber causes the arc extinguishing gas to be directed from the compression chamber through the axial hollow portion into the suction chamber thereby to be blown against an arc produced between the fixed contact and the movable contact; and the suction chamber is brought into an open condition to or communication with a space in the vessel, simultaneously when the fixed contact is drawn out of the throat portion in the insulating nozzle.
    • 吹气式气体爆炸断路器包括至少一个中断单元,其安装在填充有单一压力的灭弧气体的容器中。 所述中断单元包括:固定触点; 可移动接触件可以朝向和远离固定触头移动以分别与固定触头接合并从固定触头脱离,所述可动触头具有轴向中空部分,其中当触动件与可动触头脱离时在触点之间建立电弧 固定接触 绝缘喷嘴,其包围可动触头的自由端部,并且在其中具有与固定触头基本上封闭的喉部; 填充有灭弧气体的压缩室; 吸入室,其中压缩室内的灭弧气体被压缩,并且当可动触头远离固定触头移动时吸入室的体积增大,由此压缩室和吸入室之间的压力差导致 灭弧气体从压缩室通过轴向中空部分引入吸入室,从而被吹送到在固定触头和可动触点之间产生的电弧; 并且当固定接触件从绝缘喷嘴中的喉部部分拉出时,吸入室进入开口状态或与容器中的空间连通。
