| Outline of Final Research Achievements |
A novel method for extinction of break arcs generated in a DC high voltage circuit between electrical contacts has been proposed. The method proposes an arc extinction measure in a very small space. The purpose of this research is to realize the method. In that method, a dividing plate is inserted to the contact gap to spatially divide the arc discharge. As a result of interruption of a 600VDC-10A resistive circuit by the dividing operation, it was possible to extinguish the break arcs without lengthening them.
