摘要
根据感应电压叠加器感应腔的工作需求,针对感应腔磁芯的高效可靠应用,一般在感应腔工作前都要对磁芯进行去磁,以实现磁芯的利用最大化,减少磁性材料用量,降低设备体积和造价。通过对磁性材料性能的研究分析,得出了相对于传统的脉冲去磁方式,直流去磁具有电压低、电流小、易绝缘、电极烧蚀小、对变压器油无污染、成本低等优点的结论。根据去磁电流引入位置的不同,研究了两种使用直流对感应腔磁芯进行去磁的方法,并对这两种直流去磁的方法进行了深入地分析和模拟计算,验证了直流去磁的可行性和优越性。
Because of the working requirement of induction cell and efficient application of magnetic core,the magnetic core must be reset before the induction cell works.Reset can maximize the utilization of magnetic cores,reduce magnetic material consumption,and reduce the volume and cost of equipment.In this paper,the properties of magnetic materials are studied and analyzed.It is found that compared with the pulsed reset method,the direct current reset method has many advantages,such as low voltage,low current,little electrode erosion and low cost.According to the different import position of reset current,two direct current reset methods have been designed.Based on the theoretical analysis and numerical results,the implementation plans have been formulated.
