一种实用的三维涡流场解法

A Practical Solution for 3-D Eddy Current Problems

变压器的漏磁场分布复杂,计算工作量极大。本文利用解三维涡流场较简便的改进的—ψ方法对一台三相箔式变庄器的漏磁分布、附加损耗、涡流分布及电动力分布进行了计算,结果是合理的。从而表明改进的—ψ方法完全可以用来解决实际工程问题,的确是一种简单方便而且有效的方法。

The distribution of the leakage magnetic field in transformer is very complicated and its computation is tedious.This paper uses improved R-(?) method which is simple and convenient to calculate 3-D eddy current problems and solve the leakage magnetic field distribution additional loss and current distribution of a three-phase foil-wound transformer.The results were rational.It showed thatthe improved R-(?) can be used to solve practical engineering problem and it is indeed a convenient and efficient method.
