摘　　要：本文中笔者搭建了仿真模型,从理论方面分析了两台变压器级联空载合闸、二级变压器有载合闸产生涌流的原理,并仿真比较了四种投入操作方式产生涌流的大小。The simulation model is setted up by the authors in this paper. Based on the theory, two transformers cascade no-load closing, two-phase transformer on-load closing the principle of inrush current are analyzed. The magnitude of the inrush current generated by the four input operations are compared.
