Abstract(in Japanese) (See Japanese page)
Abstract(in English) Relay contacts mechanism with time-coordinated switching of parallel contacts is reported to suppress arc discharge suppression of the electrical arc discharge. We combined a capacitor and two relay contacts of which operations are time-coordinated. A delay circuit with a capacitor and a resistor is connected to an actuator driving circuit for the timely controlled make/break operation. 42V/5A contacts were successfully made and break without arc discharge. For much simpler mechanism, three bending beam electrodes were examined as a time-coordinated energizing and switching contacts. Using FEM (Finite Element Method) analysis, displacement and contact force of bending beams were numerically calculated for make/break operation, respectively. We confirmed possibility of the simple mechanism to suppress arc discharge.
