摘要/Abstract

摘要： 为研究退火处理对非晶合金磁特性及非晶铁心振动的影响,采用磁特性测量设备对退火前非晶带材及退火后非晶铁心的磁化特性和磁致伸缩特性进行了测量,基于测量数据建立了非晶合金卷形铁心磁-机械多物理场耦合模型,计算得出退火前后两种状态铁心各处的磁通密度分布及振动情况,并与样机振动测量数据进行了比较。结果表明:退火可提高非晶合金饱和磁感应强度,改善磁导率,并可减小磁致伸缩系数,从而有效地抑制变压器铁心的振动。

Abstract: In order to study the effect of annealing treatment on the magnetic properties and the vibration of amorphous core, the magnetization and magnetostriction properties of amorphous strip before annealing and amorphous core after annealing were measured by using the magnetic property measuring equipment. Based on the measured data, the magnetic mechanical multi physical field coupling model of amorphous roll core was established. The flux density distribution and vibration of the two kinds of iron core before and after annealing were calculated and compared with the vibration measured data of the prototype.The results show that annealing can increase the saturation magnetic induction strength of the amorphous alloy, improve the magnetic permeability, and reduce the magnetostrictive coefficient, thereby effectively suppressing the transformer core vibration.

Key words: amorphous alloy, measurement of magnetic properties, electromagnetic vibration
