Abstract
An electrical switching apparatus is disclosed with a moveable insulating nozzle for blowing an arc. According to the invention, the insulating nozzle is connected in an interlocking and force-fitting manner to at least one moveable component part of the switching apparatus by means of a clamping device and without a screw connection. Exemplary embodiments relate, inter alia, to: a clamping hold of the insulating nozzle on the moving buffer cylinder and/or at the opposite end on a part to be moved, in particular a moveable shielding electrode or an auxiliary gear mechanism for a contact system, which is driven on both sides. Advantages include: simple fitting of the insulating nozzle, small physical volume of the clamping device; precise coaxial fixing of the insulating nozzle in relation to the switch axis.
