Title: Gas-insulated disconnector (isolating switch)
Inventor: GEITEL KURT
IPC: H02B13/045
Filed: 1993-03-03
Abstract: Gas-insulated disconnectors normally have a first contact piece (1) and a second contact piece (2) opposite the first, which contact pieces are disconnected from one another by means of a disconnection gap. They are each located in a housing module (3), the housing modules (3) being connected to one another via a through opening (4).   In order that the isolation gap is effectively protected against overvoltages during maintenance and repair tasks on one of the two housing modules (3) or on devices which are connected to the contact pieces (1, 2), the space around the disconnecting gap is screened in a gas-tight manner from the environment by means of gas-tight funnel supports (17, 18).
