DC Arc Properties in a DC Magnetic Field

摘要

system was investigated. ANSYS MHD software was used to compare the simulation results of the arc (i.e. plasma) with and without an external transverse magnetic field applied. The model revealed that convective cooling was the primary mechanism for arc cooling, but while the model showed dual vortices in the convective flow pattern, the experimental results showed a more turbulent flow pattern. The experiment consisted of copper rails and fuse wire used to replicate switching contacts. A circuit at 380V
