Abstract (en)
The invention relates to a high voltage circuit breaker (1) comprising two contact elements (2) arranged opposite and movable relative to one another along a centre axis (3) of the high-voltage circuit breaker (1), and forming, during a breaking operation, in an arcing region (4) between the two contact elements (2) an arc extinguishable by an arc extinguishing gas; a heating volume (8) and a heating channel (7) connected to the arcing region (4) and configured for dissipating arc extinguishing gas (14) heated by the arc into the heating volume (8); and a cooling structure (11) embedded in the heating volume (8) and configured for cooling the heated arc extinguishing gas (14) flowing into the heating volume (8).
