Dependências da duração do arco D e lacuna de contato na extinção do arco d na velocidade de abertura do contato v são estudados para arcos de ruptura gerados em um circuito resistivo de 48 VCC em velocidades constantes de abertura de contato. A velocidade de abertura v varia em uma ampla faixa de 0.05 a 0.5 m/s. Corrente do circuito enquanto os contatos elétricos estão fechados I0 varia para 10A, 20A, 50A, 100A, 200A e 300A. Os seguintes resultados foram obtidos. Para cada corrente I0, a duração do arco D diminuiu com o aumento da velocidade de abertura do contato v. No entanto, o D at I0=300A foi mais curto do que em I0=200A. Por outro lado, a lacuna de contato na extinção do arco d tendeu a aumentar com o aumento da I0. No entanto, o d at I0=300A foi mais curto do que em I0=200A. O d foi quase constante com o aumento da v para cada corrente I0 quando o I0 foi inferior a 200A. No entanto, o d ficou mais curto quando o v foi mais lento em I0=200A e 300A. No v=0.05 m/s, por exemplo, o d at I0=300A foi mais curto do que em I0=100A. Para explicar a causa dos resultados do d, além disso, comprimento do arco imediatamente antes da extinção L foram analisados. O L tendeu a aumentar com o aumento da corrente I0. O L foi quase constante com o aumento da v quando o I0 foi inferior a 200A. No entanto, quando I0=200A e 300A, o L tendeu a se tornar mais longo quando o v foi mais lento. As características do d será discutido a partir dos resultados analisados do L e movimento de arcos de quebra. Em correntes mais altas em I0=200A e 300A, o mais curto d no mais lento v foi causado pelo amplo movimento dos pontos do arco nas superfícies de contato e pela maior deformação dos arcos de ruptura.

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.
