摘　　要：为研究新型换流变压器铁心谐波磁通抑制与损耗,以原理样机实测电流为激励,建立有限元二维仿真模型.基于场路耦合方法,对新型换流变压器是否投入感应滤波调谐装置的多种情况进行仿真.结果表明:新型换流变压器在投入感应滤波调谐装置时,能有效抑制铁心谐波磁通,降低铁心损耗,具有良好的节能效果.In order to study the core harmonic flux suppression and loss of the new converter transformer,the finite element two-dimensional simulation model is established based on the actual sample current measurement.Based on the field-circuit coupling method,the situation of whether the new converter transformer is put into the induction filter tuning device is simulated.The results show that the new converter transformer can effectively suppress the core harmonic magnetic flux when it is put into the induction filter tuning device,and the core loss is reduced,which has good energy saving effect.
