摘要
对偏转磁芯所用的铁氧体材料的磁滞损耗特性进行了分析,介绍了磁滞回线测量的方法原理,由测试结果可计算出磁滞回线面积。得出磁滞损耗功率与频率、磁通密度及温度的经验公式。对磁滞回线中涡流的影响进行了讨论,指出目前应用的偏转频率下,在磁芯损耗中磁滞损耗占主要部分。
The hysteresis loss characteristics of the ferrite material used in deflection yoke rings were studied.The principle and method of hysteresis loop measurement have been introduced.An empirical formula describing the dependence of the power of hysteresis loss on frequency,magnetic flux density and temperature was derived.The influence of the eddy current on the hysteresis loop was also discussed.The results show that under the deflection condition,the hysteresis loss dominates the total loss of the yoke ring.
