Electric field of dielectric seed separator

摘要: 针对前人建立的双绕线圈滚筒电磁场模型的不足之处，将相邻以至远邻电极的影响考虑在内，建立了双绕线圈滚筒所产生的电磁场模型。并利用它对影响电磁场的各个因素进行了分析，得出了电磁场随各参数变化的规律，并提出了改进分选效果、提高分选机性能的措施。结果表明：新建的模型克服了前人所建模型的缺点，更符合于实际情况，它对分析各因素对电磁场的影响规律以及在介电式种子分选机的参数设计时更具有指导意义。

Abstract: Taking into account the electric field intensity produced by both the neighboring electrodes and the other electrodes, a new electric field intensity model on the bifilar-winding-cylinder was developed. The new model was used to examine the factors affecting the electric field intensity. The relationship between electric field intensity and the parameters of the bifilar winding was established. Measures to improve separating effect and to increase separator performance were presented. Since the model eliminates the weaknesses of the previous models, it is more practical, and more accurate in analyzing the effect of parameters on the intensity of electric field and in designing the dielectric seed separator.
