电力变压器三维涡流场计算与屏蔽问题分析
Calculation of 3D Eddy Current Field and Analysis of Shielding in Power Transformer
摘要
Abstract
In this paper, in order to analysis the magnetic leakage field and local overheating in large power transformer, magnetic leakage field and eddy current loss in a transformer tank walls and yoke clamps are computed by using three dimensional (3D) eddy current finite element method. On that basis, the local overheating is analyzed and the corresponding shielding measures are given. The influencing factors of shielding effectiveness are analyzed. Then some reference bases are provided for design of shielding in transformer.关键词
