摘要

为降低非晶立体卷铁心变压器漏磁，减小结构件涡流损耗，文中基于变压器电磁有限元仿真技术，改进了绕组的等效三维模型，有限元仿真计算的漏感值和理论公式计算的漏感值误差为6%，验证了等效模型的准确性；针对绕组及引线结构进行优化，对比优化结构前后变压器的漏感、漏磁和损耗，结果表明：最外层绕组闭合可以有效降低变压器的漏感，引线出头位置靠近可以减小结构件上的最大磁密，减少漏磁分布，降低结构件上涡流损耗，文中中总体涡流损耗降低约62.04%。

Abstract

For reducting the magnetic leakage of amorphous three-dimensional wound core transformer and decreasing the eddy current loss of structures

in this paper the equivalent three - dimensional model of the winding is improved based on the electromagnetic finite element simulation technology of transformer. The error of leakage inductance calculated by the finite element simulation and by the theoretical formula is 6%

which confirms the accuracy of the equivalent model. The winding and lead structure are optimized

and the leakage inductance

magnetic leakage and loss of the transformer before and after the optimization of the structure are compared. The results show that the closure of the outermost winding can effectively reduce the leakage inductance of the transformer

and the proximity of the lead outlet position can reduce the maximum magnetic flux density on the structures

the leakage magnetic flux distribution and the eddy current loss on the structures.The overall eddy current loss in this paper is reduced by approximately 62.04%.
