Abstract
High speed circuit breakers(HSCB) interrupt the generated arc within the arc chute to turn off the electricity flowing through the main circuit to prevent ground faults. In order to explore the arc generated from the contactor operation, arc definition, establishment of arc interruption method, and analysis of magnetic driving force are required. In this paper, arc interruption capability has been estimated by exploring the difference in magnetic flux density of Lorenz forces using finite element analysis. In addition, since the number of grids and changes in the grid shape within the arc chute influence the formation of the inner magnetic field, its effects have been explored to enhance arc interruption capability. Assessment of interruption capability and analysis of grid shape, with rated operating current, are reported.
