    • An arc extinguishing device of a gas circuit breaker includes: an arc chamber in which an arc generated between a movable electrode and a fixed electrode is formed; a heat puffer chamber disposed so as to surround the arc chamber; a blow port in which the arc chamber communicates with the heat puffer chamber in the circumferential direction of the arc chamber; hydrogen absorbents which are disposed on an inner wall of a pressure chamber; an exhaust port which passes to the outside of an arc extinguishing chamber; and a hydrogen absorbent disposed at a position surrounding the movable electrode. Deterioration of insulation due to a product formed by decomposition of arc extinguishing gas by the arc during a contact opening operation can be suppressed.
    • 气体断路器的灭弧装置包括:电弧室,其中形成在可动电极和固定电极之间产生的电弧; 设置为围绕电弧室的热冲击室; 吹气口,其中所述电弧室在所述电弧室的圆周方向上与所述热冲洗室连通; 设置在压力室的内壁上的吸氢剂; 排气口,其通向灭弧室的外部; 以及设置在可动电极周围的位置的吸氢体。 可以抑制由于在接触打开操作期间通过电弧分解灭弧气体而形成的产品的绝缘的劣化。

    • A pipe joint is equipped with a socket and a plug, which are attachable and detachable from each other, wherein a pressure fluid introduced from the plug flows toward the socket through second holes formed in a plug valve. In addition, the pressure fluid flows smoothly along outer circumferential surfaces of the plug valve and a socket valve, and along inner circumferential surfaces of a plug body and a socket body. Further, the pressure fluid flows from the socket body to a back body, through first holes formed in the socket valve.
    • 管接头配备有可彼此附接和拆卸的插座和插头,其中从插头引入的压力流体通过形成在旋塞阀中的第二孔流向插座。 此外,压力流体沿着旋塞阀和插座阀的外周面,并且沿着塞体和插座体的内周面顺畅地流动。 此外,压力流体通过形成在插座阀中的第一孔从插座主体流到后体。
