摘要
异步式加速器的驱动线圈绕组连接,其线圈结构和连接方式直接影响磁场的耦合效果。通过数值分析,对于驱动线圈的不同连接方式分别建立串励和并励2种数理模型进行有限元分析,总结了在加速过程中驱动线圈连接方式对最终效果的影响,并且进行试验验证。通过对串励和并励的耦合效果进行研究,并同时对串、并励中2种模式下线圈的连接方式进行细化研究,分别建立瞬态模型进行仿真,总结了加速过程中不同连接方式下驱动线圈的特点。发现了不同模式下驱动线圈的电流分布不同,并励模式下的线圈电流干扰多于串励模式,导致并励模式下线圈的驱动效果弱于串励模式,电感反接模式的磁场强度高于正接模式并且加速器内磁场分布也更加广泛,导致正接条件下电枢所受推力峰值不及反接模式。基于研究内容得出串励模式下的驱动线圈对电枢的加速效果要远强于并励模式的结论,其中串励反接模式下加速器性能表现最优。
The winding connection of the driving coils in an asynchronous accelerator directly affects the magnetic field coupling effect.This paper conducts a numerical analysis to establish two mathematical models—series-excitation and parallel-excitation—for different connection methods of the driving coils and performs a finite element analysis to summarize the impact of these connection methods on the final acceleration effect,followed by experimental verification.By studying the coupling effects in series and parallel excitation modes,a detailed investigation of the coil connection methods in both modes is conducted by establishing transient models for simulation.It was found that the current distribution in the driving coils differs between the two modes:the parallel-excitation mode experiences more current interference than the series-excitation mode,resulting in weaker driving effects in the parallel-excitation mode compared to the series-excitation mode.Additionally,the magnetic field strength in the reverse polarity mode is higher than in the normal polarity mode,and the magnetic field distribution within the accelerator is also more extensive.This leads to the peak thrust on the armature under normal polarity conditions being lower than in the reverse polarity mode.Based on the study,it is concluded that the driving coils in the series-excitation mode provide a much stronger acceleration effect on the armature than those in the parallel-excitation mode,with the series-excitation reverse polarity mode exhibiting the best accelerator performance.
