Behavior of Electric Arc Inside a Quenching Chamber of High Voltage Circuit Breaker
Aubrecht, Vladimír ; Bušov, B.
A great influence on the switching process is exerted by aerodynamic relations in the quenching chamber, the direct measurement of which is hardly feasible using contemporary techniques. Therefore, the shape of the arc plasma burning between the circuit breaker contacts is scanned with a high-speed camera. The photographs from the high-speed camera represent a time analysis of the studied process, which allows through their digital processing the determination of the time changes of the arc plasma shape.
