摘要： According to an embodiment, a gas-blast circuit breaker comprises a heat removal unit in a flow path of arc extinguishing gas. The heat removal unit each includes: plate-shaped heat removal members contacting the arc extinguishing gas flowing in the flow path; and a holding portion holding the plate-shaped heat removal members to stack the heat removal members at intervals in a thickness direction. Each of the heat removal members includes: an upstream side end portion; a downstream side end portion; and a thickest portion with a largest thickness which is provided between the upstream side end portion and the downstream side end portion. Thickness of the heat removal member continuously changes between the upstream side end portion and the downstream side end portion via the thickest portion.

摘要： An interrupter unit for a circuit breaker has two electrically conductive arcing contact pieces, which can be moved relative to one another along a switching path. An insulating nozzle has a nozzle channel through which the switching path runs. A heating volume is connected to the nozzle channel. A separating housing divides the heating volume into a cold gas region and a hot gas region. A cold gas duct runs through a nozzle channel end section of the nozzle channel and is connected to the cold gas region. A hot gas duct runs through the nozzle channel end section and is connected to the hot gas region.

摘要： An electric switching device filled with a dielectric insulating medium includes first and second arcing contact, first exhaust volume downstream of first arcing contact and second exhaust volume downstream of second arcing contact. The exhaust volumes includes several first openings in their walls, through which the insulating medium exits into third volume. The third volume is arranged around the first or second exhaust volume and is radially delimited by the wall of the exhaust volumes and by an exterior wall having second openings through which the insulating medium exits the third volume. One baffle device is provided inside third volume such that vortex flow of the insulating medium is generated when it passes the baffle device on its way towards the second openings. Turbulent flow conditions are chosen such that gravitational force allows to trap or contributes to trap particles in the baffle device. The baffle device comprises baffle plates or fins, that are arranged to form cavities for capturing the particles by gravitational force.

摘要： A pressure switch including a pressure chamber and a moving disc. The moving disc is moveable in response to a pressure in the pressure chamber to cause contact between a moveable contact and a fixed contact. An orifice communicates a fluid pressure into the pressure chamber. The orifice provides a tortuous path for a fluid flow to reach the pressure chamber. An oil supply system and a generator are also disclosed.
