摘要： An electrical switch includes a tubular housing having a conductor receiving end and an operating end opposite the conductor receiving end. The tubular housing also includes a conductive interface positioned intermediate the conductor receiving end and the operating end. An operating rod extends through the operating end toward the conductor receiving end. The operating rod is moveable between a first position to engage the electrical switch and a second position to disengage the electrical switch. A gelatinous dielectric material is provided within a portion of the tubular housing, and around the operating rod, in the operating end to prevent voltage from the conductive interface from arcing to the operating end. The gelatinous dielectric material is configured to deform to maintain contact with the operating rod in the first position and the second position.

摘要： This hybrid circuit breaker has at least two series-connected arcing chambers which are operated by a common drive or by separate drives and are filled with different arc extinguishing media. The arc extinguishing and insulating medium in the first arcing chamber surrounds the second arcing chamber in an insulating manner. The aim is to provide a hybrid circuit breaker which can be produced economically and which has high availability. This is achieved, inter alia, wherein means are provided which always ensure that the movement of the first arcing chamber leads the movement of the second arcing chamber during a disconnection process, and that the movement of the second arcing chamber always leads the movement of the first arcing chamber during a connection process.
