摘　　要：铁心变压器由于铁心的作用致使等效电路和功率关系比较复杂。经过多年研究,提出将铁心能量损耗和储放等效到原、副边绕组,将铁心变压器等效为空心变压器,并设计等效电路进行验证;提出单独测量变压器各项复功率的方法并对所测功率进行修正,以检验功率关系。实验表明,铁心变压器的等效处理和复功率的测量是成功的。据此设计了铁心变压器研究性自主性实验,并介绍了这一创新实验的设计思想。Ferromagnetic core can cause the equivalent circuit and power relations to become more complicated.Through the research work for many years ,the core energy loss and storage were equivalent to the primary winding and the secondary winding , and the ferromagnetic core transformer was equivalent to air core transformer. The equivalent circuit was designed to check them. The method to measure various complex power of transformer separately was used to revise the measured power in order to check out power relationship. The experimental results show that the equivalent treatment for ferromagnetic core transformer and the complex power measurement are feasible. According to the above mention ,the research and autonomy experiment for ferromagnetic core transformer was designed and the design philosophy was presented .
