摘要
通过空间磁场和感应电压的测量 ,对自会聚偏转系统偏转磁芯中的二极场、六极场磁通密度的分布进行了计算 ,并根据磁滞损耗的经验公式对Philips 17英寸CMT的磁滞损耗进行了估测。该方法适用于估测高次谐波场对磁滞损耗的影响 ,降低能量损耗的偏转系统磁芯结构的优化 ,磁性材料的选择等。
A novel technique has been successfully developed to estimate the dipole and 6 pole magnetic flux densities by measuring the spatial distributions of the magnetic field and the induction voltages in the yoke ring of the self convergence deflection system.The hysteresis loss of Philips′ 17 inch CMT was estimated with the empirical formula.This method may possibly be used to estimate influence of high order harmonic field on hysteresis loss to optimize the design of deflection yoke ring and to develop energy saving ferrite materials.
