摘要 针对由于忽略低压引线结构漏磁场而造成配电变压器负载损耗计算误差较大的问题,以大电流箔绕变压器为例,建立考虑绕组和引线结构复合漏磁场的变压器仿真模型,基于复合漏磁场模型并通过场路耦合仿真方法计算箔式绕组损耗和结构件损耗,最后将负载损耗各组分计算值与试验值进行对比分析。分析表明,仿真计算值与试验值误差小于5%,证明该计算方法具有较高准确度,可有效指导能效变压器设计。

Abstract：In response to the problem of significant calculation errors in transformer load loss caused by neglecting the leakage magnetic field of low-voltage lead structure, taking a high current foil wound transformer as an example, a transformer simulation model considering the composite leakage magnetic field of coil and lead structure is established. Based on the composite leakage magnetic field model, the loss of the foil winding and structural component loss are calculated using field circuit coupling simulation method. Finally, a comparative analysis is conducted between the calculated values and the test values. The analysis shows that the error between the simulation calculation value and the test value is less than 5%, indicating that this calculation method has high accuracy and can effectively guide the design of energy efficiency transformers.
