摘要
In this study,a possible method of reducing the flashover stress is achieved by the effect of an additional magnetic field in the transverse direction on the main applied electric field.The degree of vacuum used in this study was 5×10^(5) Pa.The magnetic flux density B employed in this study extends from 4×10^(3) to 24×10^(3) T.From the results obtained throughout this work,the transverse magnetic field increases the flashover voltage and decreases the leakage current.The effect of the transverse magnetic field on the surface flashover of the dielectric solid in vacuum shows a marked dependence on the material and the thickness of the test specimen,the vacuum degree,the type of electric field(AC or DC)as well as the type of magnetic field(AC or DC).
