Analysis on Nonlinear and Anisotropic Electric Field about Valve-side Winding of Converter Transformer
摘要
Abstract
The nonlinearity and anisotropy of insulating materials ought to be considered in calculation of the electric field about valve-side winding of a converter transformer, as resistivity of insulating materials is nonlinear and anisotropic. In this paper, ANSYS secondary development is adopted to calculate the nonlinear DC electric field and the nonlinear and anisotropic DC electric field by taking into account the variations of insulation resistivity with temperature and electric field. The results show that the electric field distribution is very different in consideration of the nonlinearity and anisotropy of resistivity of insulating materials compared with that without considering these conditions. Therefore, the electric field about valve-side winding of a converter transformer should be calculated according to nonlinear and anisotropic electric field.关键词
