ABSTRACT:
The switching chamber is intended for a gas-insulated high-voltage switch. It contains a housing filled with insulating gas and a contact arrangement held in the housing. The contact arrangement has, in a coaxial arrangement, the following components: two switching pieces, which are capable of being moved relative to one another along an axis, with in each case one arcing contact and in each case one tubular conductor containing a rated current contact, an insulating nozzle, and a compression apparatus with a fixed piston and a cylinder. A moveable tubular conductor of the two tubular conductors forms the wall of the cylinder, is electrically conductively and rigidly connected to one of the two arcing contacts via a base of the cylinder and bears the insulating nozzle.
