摘要： A method of evacuating hot gases produced in a current breaking operation by a high voltage circuit breaker (1) which comprises a metal outer tank (2) filled with insulating gas, a casing (3) having gas outlet ports (30) and arranged inside the metal outer tank (2), with which it is in communication via the said ports, characterized in that insulating gas (GI) is aspirated from inside the casing (3) in a direction parallel to the flow of the hot gases (GC) produced by the current breaking operation, so as to mix the gases inside the casing (3) before they are evacuated, through the said gas outlet ports (30) of the casing, into the interior of the metal outer tank (2). The invention also relates to an associated high voltage circuit breaker, which includes means (5) for aspirating insulating gas from the interior of the casing (3), in a direction parallel to the hot gas stream.
