    • PROBLEM TO BE SOLVED: To provide a current interrupting chamber of a power circuit breaker.
      SOLUTION: The current interrupting chamber (100) equipped with a moving assembly axially movable between a start position and an end position of an operation for opening a circuit breaker, is provided with a first compression chamber(106), a hollow drive tube (108) having ports (136) for bringing its interior into communication with the outside of the current interrupting chamber, a second compression chamber (120), and means (124, 134) for obstructing the ports of the drive tube as from the start position of an operation for opening the circuit breaker and up to an intermediate position which is reached between the position of separation of two arcing contactors from each other and the end position of an operation for opening the circuit breaker.

    • PROBLEM TO BE SOLVED: To provide a puffer type gas circuit breaker with improved breaking performance and insulation performance.SOLUTION: A partition wall 13 is provided to a stationary cylinder 11 on a movable side of a puffer type circuit breaker to form a stationary cylinder internal space S3. A machine puffer chamber S2 is provided adjacent to one flange part of the partition wall 13, and a hot gas exhaust chamber S4 is provided on the other flange part of the partition wall 13. The stationary cylinder 11 has a gas suction hole 11a, a gas exhaust hole 11b, and a hot gas exhaust hole 11c. The gas suction hole 11a and the gas exhaust hole 11b are communicated with the stationary cylinder internal space S3, and the hot gas exhaust hole 11c is communicated with the hot gas exhaust chamber S4, respectively. The hot gas exhaust hole 11c is provided in a radial direction of the stationary cylinder 11, and is communicated with the shaft exhaust hole 12a after an arc is generated. The gas suction hole 11a is arrange on one of virtual planes dividing the stationary cylinder 11 into two in the radial direction, and the hot gas exhaust hole 11c is arranged on the other virtual plane.
    • 要解决的问题:提供一种具有改进的断裂性能和绝缘性能的河豚式气体断路器。解决方案:在吹气式断路器的可动侧上的静止气缸11上设置分隔壁13,以形成内部的固定气缸 空间S3。 在分隔壁13的一个凸缘部分附近设置有机气冲洗室S2,在分隔壁13的另一个凸缘部分设置热气体排出室S4。固定筒11具有气体吸入孔11a, 排气孔11b和热气体排出孔11c。 气体吸入孔11a和排气孔11b与固定筒内部空间S3连通,热气体排出孔11c分别与热气体排出室S4连通。 热气体排出孔11c沿静止圆筒11的径向设置,在产生电弧之后与排气孔12a连通。 气体吸入孔11a配置在将固定筒11分割为径向的虚拟平面中的一个,热气体排出孔11c配置在另一个虚拟平面上。
