Dépendances de la durée de l'arc D et espace de contact à l'extinction de l'arc d sur la vitesse d'ouverture des contacts v sont étudiés pour les arcs de coupure générés dans un circuit résistif 48VDC à vitesses d'ouverture de contact constantes. La vitesse d'ouverture v varie sur une large plage de 0.05 à 0.5 m/s. Courant de circuit lorsque les contacts électriques sont fermés I0 varie de 10A, 20A, 50A, 100A, 200A et 300A. Les résultats suivants ont été obtenus. Pour chaque courant I0, la durée de l'arc D diminue avec l'augmentation de la vitesse d'ouverture des contacts v. Cependant, l' D at I0=300A était plus court que celui de I0=200A. D'autre part, l'intervalle de contact à l'extinction de l'arc d tendait à augmenter avec l'augmentation du I0. Cependant, l' d at I0=300A était plus court que celui de I0=200A. Le d était presque constant avec l'augmentation du v pour chaque courant I0 lorsque le I0 était inférieur à 200A. Cependant, le d est devenu plus court lorsque le v était plus lent à I0=200A et 300A. Au v=0.05 m/s, par exemple, le d at I0=300A était plus court que celui de I0=100A. Pour expliquer la cause des résultats du d, de plus, longueur de l'arc juste avant l'extinction L ont été analysés. Le L tend à augmenter avec l'augmentation du courant I0L’ L était presque constant avec l'augmentation du v lorsque le I0 était inférieur à 200A. Cependant, quand I0=200A et 300A, le L avait tendance à s'allonger lorsque le v était plus lent. Les caractéristiques du d sera discuté à partir des résultats analysés du L et le mouvement des arcs de rupture. À des courants plus élevés à I0=200A et 300A, le plus court d au plus lent v a été causée par un mouvement large des points d'arc sur les surfaces de contact et une déformation plus importante des arcs de rupture.

Abstract: Dependences of arc duration D and contact gap at arc extinction d on contact opening speed v are studied for break arcs generated in a 48VDC resistive circuit at constant contact opening speeds. The opening speed v is varied over a wide range from 0.05 to 0.5m/s. Circuit current while electrical contacts are closed I0 is varied to 10A, 20A, 50A, 100A, 200A, and 300A. The following results were obtained. For each current I0, the arc duration D decreased with increasing contact opening speed v. However, the D at I0=300A was shorter than that at I0=200A. On the other hand, the contact gap at arc extinction d tended to increase with increasing the I0. However, the d at I0=300A was shorter than that at I0=200A. The d was almost constant with increasing the v for each current I0 when the I0 was lower than 200A. However, the d became shorter when the v was slower at I0=200A and 300A. At the v=0.05m/s, for example, the d at I0=300A was shorter than that at I0=100A. To explain the cause of the results of the d, in addition, arc length just before extinction L were analyzed. The L tended to increase with increasing current I0. The L was almost constant with increasing the v when the I0 was lower than 200A. However, when I0=200A and 300A, the L tended to become longer when the v was slower. The characteristics of the d will be discussed using the analyzed results of the L and motion of break arcs. At higher currents at I0=200A and 300A, the shorter d at the slowest v was caused by wide motion of the arc spots on contact surfaces and larger deformation of break arcs.
