摘要
为解决取能电流互感器的在线取能电源设计时,当一次电流较大导致取能铁芯饱和从而使铁芯输出功率难以量化计算分析的问题,利用有限元方法对电流互感器取能电源进行了建模及分析,通过对一实际开口铁芯取能电源进行建模仿真,得到了不同母线电流及负载下铁芯的输出功率及负载电压波形,利用取能铁芯的磁感应强度云图定量分析了铁芯饱和情况。模型仿真结果与实际开口铁芯电源的实测结果的对比验证了模型的正确性。该模型可用于指导实际电源的参数设计。
In the design of online power-carrying power supply of the current transformer mode,the energy-carrying iron core is saturated due to the large primary current.So,the output power of the iron core is difficult to be quantified and analyzed.In this paper,the finite element method was used to analyze the power supply of current transformer.By modeling and simulating an actual opening core power supply,the output power and load voltage waveforms of the core under different bus currents and loads were obtained.The magnetic saturation of the core was quantitatively analyzed.The simulation results of the model were compared with the actual measured results of the actual opening core power supply,which verified the correctness of the model.This model can be used to guide the parameter design of actual power supply.
