Abstract

To realize the high voltage vacuum circuit breaker, we investigated the voltage distribution ratio after current interruption at the double-break vacuum circuit breaker. We used the spiral CuCr (20 %) electrodes and the axial magnetic field CuCr (50 %) electrodes as the experimental electrodes. At the double-break vacuum circuit breaker, where two vacuum valves that had same and different characteristics of the electrode structure and contact materials were connected in series, there was a bias in the voltage distribution ratio of each vacuum valve after current interruption. This seems to be because there was difference in the residual current that passed through each vacuum valve after current interruption
