Abstract (en)
[origin: EP0951042A2] The power switch comprises at least one burn-up switching arrangement which comprises two parts, and an arc chamber (5) between the switching parts. An exhaust (9) connects the arc chamber with an exhaust volume (8). At least one pressure chamber (6) is connected over the arc chamber with the exhaust. At least one explosive charge (10) is triggered at a switch-off, and is, at least partially converted into a gas. The power switch comprises at least one burn-up switching arrangement which comprises a first switching part and a second switching part, movable along a switching axis (2) between an on position, in which it touches the first switching part, and an off position, in which it is in a distance from it in axial direction, releasing an arc chamber (5) between the switching parts. At least one exhaust (9) connects the arc chamber with at least one exhaust volume (8). At least one pressure chamber (6) is connected over the arc chamber with the, at least one exhaust. At least one explosive charge (10) is triggered at a switch-off, and is, at least partially converted into an extinguishing gas current.
