Originální abstrakt

Breaking of an electric circuit is accompanied by the formation of an electric arc between the circuit breaker contacts. A reliable function of the circuit breaker depends on several factors, the most important of which include: mechanical resistance of the individual components, circumstances of the switching arc extinction and the associated recovery of the dielectric strength of the medium between the circuit breaker contacts. A great influence on the switching process exert also the 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 switching arc in the quenching chamber is simultaneously photographed from two fixed rectangular directions. Photographs from the high-speed camera represent a time analysis of the studied process which allows through their computational digital processing determination and visualisation of time changes of the arc plasma shape in 3D.
