    摘要： This power breaker has at least one quenching chamber, which is filled with an insulating medium, is of cylindrical design, extends along a central axis (2) and has a power current path, having two stationary consumable contact arrangements (5, 6) which are arranged on the central axis (2), are at a distance from one another in the axial direction and are arranged in the power current path. In the connected state, the consumable contact arrangements (5, 6) are electrically conductively connected by means of a moving bridging contact. An arc zone (24) is provided between the consumable contact arrangements (5, 6). A rated current path is arranged in parallel with the power current path. The power breaker is provided with at least one source for a highly pressurized insulating medium. The medium passes from this source directly into the arc zone (24), through at least one injection channel (62, 63). This high-pressure injection considerably improves the breaking capacity of the power breaker.

    摘要： The movable nozzle of a puffer circuit interrupter has a coaxial cylindrical shield connected to its downstream end and the main movable contacts connected to its upstream end. The shield is electrically connected to the stationary contact terminal. The movable contact ring and coaxial shield at the upstream end of the nozzle define a well shielded open gap when the interrupter gap opens.

    摘要： The compressed gas-blast circuit breaker includes two moving contact members (1, 2) which are guided to move counter to one another along an axis (3) in a chamber which is filled with insulating gas. These contact members each have an arcing contact (8, 9) and a main current contact (6, 7). An insulating nozzle (10) mounted on a contact member (1) is moved directly by a drive, and compressed gas is passed, during disconnection, through the constriction (11) in the insulating nozzle (10) into an exhaust space (14) from a pressure space (12), which is independent of the switching travel, and/or from a compression space (19), which is operated by the contact members. Drive force is passed to a contact member (2), which absorbs force, from the directly-driven contact member (1), through an insulating part and a speed converter. During disconnection, if the functionally essential parts of the force-absorbing contact member (2), such as the arcing contact (9), the main current contact (7) and the shields, are suitably driven, it forms an insulating path, which can be highly stressed dielectrically, in a short time while optimally using a comparatively small drive force.
