Investigation of diffuse current in arc boundary by electric probes
Original language description
Electric probes were used for investigation of an intermediate layer between the arc and anode surface in regions outside the main current channel. Distributions of a diffuse current and the potential were measured. Resistance and heating of the intermediate layer by diffuse current were evaluated. It was found that not only the value of diffuse current strongly depends on distance from the arc but also the shape of the distribution and the position of the maximum of the current change with the distance. These trends can be explained by expanding of the plasma jet. Evaluated equivalent intermediate layer resistance shows widening of the conductive region in a stream wise direction. Variation of resistivity of the intermediate layer is much higher thanvariation of the potential drop on the layer. That means that distributed current as well as Joule heating of the layer are generally controlled by distributed resistance.

Difuzní proud v hraniční oblasti oblouku měřený elektrickými sondami
Czech description
Vlastnosti přechodové vrstvy mezi hranicí elektrického oblouku a povrchem anody byly zjišťovány elektrickými sondami. Bylo změřeno rozložení difuzního proudu a potenciálu a vyhodnoceno rozložení odporu v přechodové vrstvě. Ukazuje se, že rozložení proudua Jouleův ohřev vrstvy jsou dány rozložením odporu.
