| 摘 要： | 将JA模型与电磁场数值分析方法相结合,在考虑铁心的磁滞效应的情况下,推导出电磁场的有限元计算模型。分别采用基本磁化曲线和磁滞回线两种不同的方法对电抗器的电磁场进行仿真计算。研究结果表明磁滞现象对电抗器电磁场的计算影响较大,因此考虑磁滞效应的电磁场数值计算模型,为进一步研究电抗器的发热问题奠定了理论基础。

| Abstract: | The electromagnetic field finite element numerical model of the reactor, considered the hysteresis effect of the ironcore, was derived by combining the JA model and the numerical analysis method. The electromagnetic field distribution of the reactor was analyzed by using the two methods of single value basic magnetization curve and hysteresis loop, respectively. The results showed that the magnetic hysteresis had a great influence on the calculation results of the electromagnetic field distribution of the reactor. The electromagnetic field computing model considering the hysteresis effect of the ironcore lays a foundation for further research on the reactor heat. |
