Switchgear arrangement

摘要

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.

1. A switchgear arrangement, comprising:
an interrupter unit having first and second switching contact pieces movably disposed relative to one another; an arcing gas channel issuing from an arc gap to be formed between said switching contact pieces, passing through said interrupter unit and connecting said arc gap to a surrounding environment of said interrupter unit; a hollow-volume vessel arrangement having a first end connected at one of said contact pieces and at least sectionally delimiting said arcing gas channel; said hollow-volume vessel arrangement having a second end opposite said first end, said second end being formed with a lateral-surface-side outlet opening of said arcing gas channel into the surrounding environment of said interrupter unit; said hollow-volume vessel arrangement having a substantially pot-shaped fitting body at said second end; a pipe body, dividing said arcing gas channel in the form of shells, and passing through said hollow-volume vessel arrangement on an inner lateral surface side, said pipe body having, on the lateral surface side, at least one through-opening, via which shells separated by said pipe body communicate with one another; said outlet opening and said at least one through-opening being offset with respect to one another.
