Research on Electrical Field Numerical Calculation Safety Evaluation in Cylindrical Silo Filled Powder

摘要

The design ideas and characters of a calculation software on field distribution when ohmic dielectrical powder is filled into cylindrical silo are presented in this paper. Also inclusion in its discussion is the static safety evaluation in silo with practice in China. It is raised that, at the beginning of the filling operation or nearly full filled, the undulating change of the field should be one of the reasons which may cause incentive ESD.
