摘　　要：基于多绕组磁链耦合的原理,建立了一种基于曲折型自耦变压器的节电器稳态模型,重点分析该节电器零序等值电路的特性,说明其既可滤除负载的零序基波和谐波电流,又可避免因电源侧电压的零序分量产生较大的零序电流,仿真结果证明理论分析的正确性。According to the principle of multi-winding flux coupling, this paper presents a steady-state model of power-saver based on the zig-zag type auto-transformer. The characteristic of the power-saver equivalent circuit is studied in detail. The analysis shows the power-saver can filter out zero-sequence first harmonic and harmonic load currents, and reduce the zero-sequence current caused by the zero- sequence component of power source. The simulation results testify the aforementioned theoretical analysis.
