要約(英語): For improving the current direct current circuit breakers (DCCBs) performance and providing new insights for creating next generation DCCBs, it is important to analyze the arc plasma extinguishment process with considering the application of recovery voltage (RV). In this study, a three dimensional electromagnetic thermal fluid simulation program was developed and the comparison between without and with RV application along with applying different intensities external magnetic field was implemented. It found out that the interruption time increased with applying the RV because of the residue of high-temperature gas and metal vapor in the inter-electrode area, and the re-strike phenomenon or current path division occurred even with the external magnetic field applied.
