    摘要： This power circuit-breaker has at least one cylindrically constructed arcing chamber which is provided with a stationary contact, with a moving contact and with a quenching zone between the two contacts. A shaft of the moving contact is permanently connected to a blowout volume which is closed off on the stationary contact side by an insulating nozzle through which at least one flow channel passes. The arcing chamber has a first compression volume which is operatively connected to the blowout volume and to a second compression volume. It is intended to provide a power circuit-breaker in which the blowing-out of the arc with pure SF.sub.6 gas is made stronger. This is achieved by providing a moving auxiliary piston between the first compression volume and the second compression volume and by the auxiliary piston being connected to the moving contact via a direction-changing device.

    摘要翻译： 该电源断路器具有至少一个圆柱形构造的电弧室，该电弧室设置有具有可移动触点的固定触点和两个触点之间的淬火区域。 可移动触点的轴永久地连接到通过至少一个流动通道通过的绝缘喷嘴在固定触点侧封闭的吹出口。 电弧室具有可操作地连接到吹出体积和第二压缩体积的第一压缩体积。 旨在提供一种电源断路器，其中使具有纯SF6气体的电弧吹出更强。 这通过在第一压缩容积和第二压缩容积之间提供移动的辅助活塞，并且辅助活塞经由方向改变装置连接到移动触点来实现。
