Abstract
Arc physics and characteristic control are the basic and important technological issues in the field of electric power apparatus. Enormous studies have been carried out in academic and industrial institutions in recent decades, which strongly support the development of high-performance power switchgear and the technological advancement. This paper reviews the recent research progress in high and low-voltage gas switchgear with air and SF6 and their alternative gases from the following aspects: physical parameters (including thermodynamic properties, transport coefficient, collision cross section, thermal critical breakdown field strength and so on), arc Magneto-Hydro-Dynamical (MHD) model simulation and its application, effects of different factors on the arc characteristics and its control regulations and so on. Besides, some issues are proposed and should be deal with in further study, involving the experimental measurement of arc plasma thermodynamic parameters, the arc model of three-dimensional gas switchgear considering the non-equilibrium breakdown process in the post-arc period, the physical characteristics of DC fault arc and the efficient detection technology, the arc extinguishing technology of SF6 alternative gas. Some valuable references are expected to provide for exploration on the gas switchgear arc theory, arc extinguishing technology and new power switchgear equipment.
