Air flow in quenching chamber

Air flow in quenching chamber

Paper in proceedings (conference paper)

Problem of electric arc quenching accompanies designers from the very beginning to the final end. The whole construction of electric apparatus runs upon quenching chamber and quenching system at all. Requirement of minimization forces the designers to the better solutions of the quenching chamber design, current-carrying conductor from the electrodynamic forces or thermal field point of view. Problem arises during an electric arc switching, when extreme pressure and thermal conditions exist in the circuit breaker. Accumulated energy needs to be get off from the circuit breaker easily and quickly, due to the possibility of the apparatus destruction. Thats the reason why the aerodynamics is important inside circuit breaker.
