双分裂变压器短路阻抗的分析求解

Analysis and Solution of Short Circuit Impedance of Double Split Transformer

随着发电机组以及电力变压器的容量的不断增加,系统中的短路容量也在不断增大,分裂变压器的应用也在随之增加。但分裂变压器不同于传统变压器,其独特的绕组结构对短路阻抗的计算造成了一定的难度,基于此,利用能量法和解析法就双分裂变压器独特的绕组结构对穿越阻抗、半穿越阻抗分别进行了解析,为变压器的优化设计提供了有效参考。

With the increasing capacity of generating units and power transformers,the short-circuit capacity in the system is also increasing,and the application of splitting transformers is increasing.But the split transformer is different from the traditional transformer,its unique winding structure on the calculation of short-circuit impedance caused a certain degree of difficulty,so the use of energy and analytic method on the dual split transformer unique winding structure on the crossing impedance and the half-through impedance were analyzed,Which provides an effective reference for the optimization design of the transformer.
