变压器漏磁场及其对绕组涡流损耗影响的研究

Research on Leakage Magnetic Field and Effect on The Eddy Loss in Transformer Windings

利用有限元分析软件OPERA对电力变压器漏磁场进行了分析,并着重论述了横向漏磁场对变压器绕组涡流损耗所造成的影响,确定了一种使其所产生的绕组漏磁场分布合理和涡流损耗较小的线圈安匝布置方案。

The paper analyzes the leakage magmetic field in transformer based on the use of finite element method （FEM） software OPERA, and emphatically discusses the influence of transformer radial leakage flux to the eddy loss in windings. A kind of ampereturn arrangement is determined which has more reasonable leakage field distribution and less eddy losses in the transformer windings.
