摘要： 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.

摘要： The heavy-duty circuit-breaker having an axis (A), and having an arcing contact piece, a current-carrying element and an erosion protection element, with the arcing contact piece having an opening in order to carry an essentially axial flow of a gas which has been heated by an arc, and together with the current-carrying element forms a flat contact (F) in order to carry a short-circuit current (I) which flows through the arcing contact piece and the current-carrying element, and with the erosion protection element essentially shielding the current-carrying element from the flow close to the flat contact (F), is characterized in that the current-carrying element has an axial area in which a radial internal dimension (d2) of the current-carrying element increases in steps or continuously as the distance from the flat contact (F), measured parallel to the axis (A), increases.

摘要： The heavy-duty circuit-breaker having an axis (A) which defines an axial coordinate (z) parallel to the axis and a radial coordinate (r) at right angles to the axis, and having an arcing contact piece, a current-carrying element and an erosion protection element, with the arcing contact piece having an opening in order to carry an essentially axial flow of a gas which has been heated by an arc which may be based on the arcing contact piece, and together with the current-carrying element forms a flat contact (F) in order to carry a short-circuit current (I) which flows through the arcing contact piece and the current-carrying element for the time during which the arc burns, and with the erosion protection element essentially shielding the current-carrying element from the flow close to the flat contact (F), is characterized in that the current-carrying element has an axial area in which a radial internal dimension (d2) of the current-carrying element increases in steps or continuously as the distance from the flat contact (F), measured parallel to the axis (A), increases. The axial area is advantageously intended, to hold the erosion protection element.
