Abstract
A switchgear has an interrupter unit that includes an arc gap. A first and a second switching contact piece are movable relative to one another. A switching-gas duct originates in the arc gap and connects the arc gap to the surroundings of the interrupter unit. A hollow vessel arrangement delimits at least some sections of the switching-gas duct and is connected to one of the contact pieces. The hollow vessel arrangement includes an external outlet opening for the switching-gas duct.
