Soft magnetic ferrite material for network transformer and preparation method thereof
The invention discloses a soft magnetic ferrite material for a network transformer. The raw materials of the soft magnetic ferrite material comprise main components and auxiliary components, wherein the main components comprise the following materials in percentage by weight: 70.0%-72.0% of Fe2O3, 10.0%-12.0% of ZnO and the balance of MnO; the content of the auxiliary components is calculated according to the percentage of the total weight of the main components, the auxiliary components comprise the following materials in percentage by weight: 200 ppm to 400 ppm of CaO, 300 ppm to 500 ppm ofNiO, 400 ppm to 700 ppm of Nb2O5, 1500 ppm to 4000 ppm of Co2O3, 30 ppm to 70 ppm of SiO2 and 150 ppm to 300 ppm of V2O5. The technical problems that in the prior art, the incremental magnetic conductivity of a soft magnetic material of a network transformer does not reach 3000 at the high and low temperature points of -40 DEG C and 85 DEG C, and the incremental magnetic conductivity is low are solved.
本发明公开了一种网络变压器用软磁铁氧体材料，其原料包括主成分和辅助成分；所述主成分含量以氧化物重量百分百计为：FeO为70.0～72.0％、ZnO为10.0～12.0％、其余为MnO；辅助成分含量按主成分总重量的百分比计为：CaO 200～400ppm、NiO 300～500ppm、NbO400～700ppm、CoO1500～4000ppm、SiO30～70ppm和VO150～300ppm；解决了现有技术网络变压器的软磁材料在‑40℃和85℃这两个高低温温度点增量磁导率都没有达到3000，增量磁导率偏低等技术问题。
