摘　　要：复杂激励条件下,变压器绕组引起的漏磁场在结构件中会产生杂散损耗造成局部过热,严重时会产生运行事故,对结构件杂散损耗的精准测量方法以及采取有效措施降低损耗已经成为变压器结构设计和优化中备受关注的问题。基于TM21实验模型,提出一种将实验测量和仿真精准计算相结合的办法对复杂激励条件下变压器结构件杂散损耗的测量方法。该方法可以为变压器及平波电抗器类产品设计与优化提供有效帮助。Under complex excitation conditions,the leakage magnetic field caused by transformer winding will cause stray loss in the structural parts,which will cause local overheating,and serious operation accidents.Accurate measurement methods of stray loss of structural parts and effective measures to reduce the loss have become the focus of attention in the structural design and optimization of transformers.Based on TM21 experimental model,this paper proposes a method to measure stray loss of transformer structure under complex excitation conditions by combining experimental measurement with accurate simulation calculation.This method can provide effective help for the design and optimization of transformer and smoothing reactor products.
