“…According to simulation results of transition from supersonic to subsonic status, the ion temperature is about 10 eV. This is also supported by SCHELLENKENS's experimental results [12] . From KUTZNER and MILLER's experimental results [13] , the mean charge number of ions is 1.85.…”

“…In SCHELLEKENS's research [12] , the distributions of electron temperature along the radial direction (at z = 5 mm, the middle of the electrode separation) and along axial direction (arc axis, r = 0 mm) have been obtained through experiments.

“…In this paper, based on the quasi-steady model [10,11] , vacuum arc characteristics at different arcing moments are simulated and analyzed by considering a series of discrete moments of the sinusoidal current, which is because the relaxation time of vacuum arc plasma is far less than the characteristic time of a power system. Moreover, simulation results are partly compared with the experimental results [12] .…”

In this paper, based on the quasi-stationary magneto-hydrodynamic (MHD) model, vacuum arc characteristics are simulated and analyzed at different moments under power-frequency current. For a vacuum arc with sinusoidal current under a uniform axial magnetic field (AMF), simulation results show that at the moment of peak value current, maximal values appear in the ion number density, axial current density, heat flux density, electron temperature, plasma pressure and azimuthal magnetic field. At the same time, the distributions of these parameters along the radial position are mostly nonuniform as compared with those at other moments. In the first 1/4 cycle, the ion number density, axial current density and plasma pressure increase with time, but the growth rate decreases with time. Simulation results are partially compared with experimental results published in other papers. Simulations and experimental results both show that the arc light intensity near the cathode side is stronger than that near the anode side for diffusing vacuum arcs.
