【摘要】：對(duì)Fe73.5Cu1Nb3Si13.5B9納米晶鐵芯分別進(jìn)行普通熱處理與橫磁處理,并檢測(cè)鐵芯經(jīng)兩種熱處理后的各項(xiàng)磁性能。獲得了各頻率下?lián)p耗與幅值磁密的關(guān)系。結(jié)果表明,橫磁處理降低損耗效果較明顯,該方法在高頻電力電子變壓器鐵芯領(lǐng)域具有潛在應(yīng)用前景。損耗分離結(jié)果表明,橫磁處理后,磁滯損耗、渦流損耗、剩余損耗在總損耗中所占比例分別為不變、升高、降低。橫磁處理后,磁疇結(jié)構(gòu)改變,以磁矩旋轉(zhuǎn)磁化為主要磁化方式,降低疇壁共振造成的異常損耗是除降低磁滯損耗外,降低總損耗的另一原因。
[Abstract]:The Fe73.5Cu1Nb3Si13.5B9 nanocrystalline cores were ordinary heat treatment and transverse magnetic treatment, and the detection of the core magnetic properties of two kinds of heat treatment. The relationship between the density and amplitude of each frequency magnetic loss was obtained. The results show that the transverse magnetic treatment reduces the loss of the effect is obvious, this method has a potential application prospect in high frequency power electronic transformer core loss field. Separation results show that the transverse magnetic treatment, hysteresis loss, eddy current loss and residual loss in the total loss ratio was unchanged, increased, decreased. The transverse magnetic treatment, magnetic domain structure change, with magnetic moment rotation magnetization as the main mode of magnetization, reduce the abnormal loss caused by domain wall resonance in addition to reduce hysteresis loss, reduce the total loss of another reason.
