The Electric Field Characteristics Analysis of Converter Transformer Considering Anisotropic

Abstract:

Simulation and analysis of the converter transformer valve side’s transient electric field by finite element method is proposed. The electric field of converter transformer valve side’s is calculated under polarity reversal condition, the maximum value of the electric field intensity of insulating materials and the potential distribution of the before and after first polarity reversal are given, obtaining the electric field distribution characteristics of the oil-paper insulation material in the case of isotropic and anisotropic before and after the first polarity reversal, and made a comparison. The numerical calculation result of the converter transformer valve side’s electric field is also given, and the comparison of the calculation results in the case of isotropic and anisotropic, for before and after the first polarity reversal is analyzed, obtaining the variation rule of the converter transformer valve side’s electric field and the variable factors which affected the distribution of the electric field.
