Abstract
A gas-insulated switch has a first contact and a second contact. A contact unit is connected to the first contact as a movement contact unit having a drive unit and is movably mounted along a switch axis. The gas-insulated switch further has a multi-part insulation nozzle system with a primary nozzle and an auxiliary nozzle. A heating channel is formed between the primary nozzle and the auxiliary nozzle. The heating channel originates from an electric arc chamber and opens in a gas reservoir, wherein the gas reservoir is delimited by a ram. The gas reservoir is radially delimited by a wall, in respect of the switch axis, which is not a component of the movement contact unit, and the ram is part of the movement contact unit and is movably mounted such that the ram moves along the switch axis away from the second contact to enlarge the gas reservoir.
