Experimental verification of properties of circuit breaker quenching chamber
Kadrnka, Petr ; Vávra, Zdeněk (referee) ; Valenta, Jiří (advisor)
The circuit breakers are able to switch on and off automatically either the short circuit currents up to the limits of their breaking capacity. While the disconnection of the contacts in the switching devices are generated by the arc then it is needed to put it out quickly. A manner of the arcing in the electrical switching devices is influenced by several different factors. It must be taken into account the dynamics of a plasma, a current flowing in the electrodes, a flowing stream in a plasma and a magnetic field generated by a flowing current. This paper is devoted to describe the manner of the arcing in the arc chamber. The experiments carried out in an experimental way attempt to explain, specify and thoroughly comprehend the movements and the characteristics of the arc in a metal arc and in a metal enclosure circuit breaker.
