摘要

建立了超高压变压器线圈、等电位屏蔽和套管端部的三维实体模型。根据线圈的对称结构，对模型进行了适当的简化。采用有限元法计算了变压器高压线圈和等电位屏蔽周围的电场强度分布，特别是找到了最大电场强度。采用零阶优化方法，最大电场强度显著降低27%。计算和优化结果为超高压变压器线圈和等电位屏蔽的设计提供了依据。

Electric field calculation and optimization of ultra-high voltage transformer equipotential shielding

A 3-D substantial model is built for an ultra-high voltage transformer coil, the equipotential shielding and the bushing end. This model is properly simplified according to the symmetrical structure of the coil. The electric field intensity distribution around the transformer high-voltage coil and the equipotential shielding are calculated on the basis of the finite element method, especially the maximum electric field intensity is found. With the zero-order optimization method, the maximum electric field intensity is significantly decreased by 27%. The calculation and optimization results provide basis for designing the coil and equipotential shielding of an ultra-high voltage transformer.
