要約(日本語): The breakdown factors in magnetic driven arcs have been elucidated in previous research to improve the performance of DC circuit breakers. However, few researchers have researched about the spectrum intensity around the next re-strike spot area before re-strike with the application of an external magnetic field. The breakdown in a magnetic driven arc depends on whether the preceding particles near the new anode spot are dominated by Cu I or Cu II. When Cu I dominates, there is no acceleration of the charged particles by the electric field, and thermal breakdown anode spot high-temperature Cu I vapor is considered. When Cu II dominates, the charged particles are accelerated by the magnetic and electric fields, and thermal breakdown, dielectric breakdown, or both. Therefore, Cu I and Cu II emitted from anode spot affected by the external magnetic field is paid attention to, and multi-spot spectroscopic measurements were performed by a spectrometer and a high-speed video camera to capture the rapid phenomenon.
