摘要 基于磁致伸缩测量装置及爱波斯坦方圈测量单片硅钢片轧制方向(RD)与垂直于轧制方向(TD)的磁致伸缩及磁化特性,采用正交插值法计算开有气隙的并联电抗器模型铁心及尺寸相同无气隙的变压器模型铁心的磁致伸缩应变。同时考虑磁致伸缩及麦克斯韦力的影响,通过仿真软件对不同激励电压下并联电抗器与变压器模型铁心的振动进行仿真分析。然后单独考虑麦克斯韦力的影响,对上述两个模型铁心振动进行计算,并与考虑磁致伸缩与麦克斯韦力同时作用下的铁心振动进行定量化对比分析。结果表明,麦克斯韦力是无气隙垫块的并联电抗器模型铁心振动的主要原因,而其对变压器模型铁心振动的影响可以忽略。最后搭建上述两个模型铁心振动测量试验平台,试验结果与仿真结果具有良好的一致性。

Abstract:In this paper, the magnetostrictive and magnetization properties in rolling direction (RD) and transverse direction (TD) of silicon steel sheet are measured by magnetostriction measurement device and Epstein frame. The magnetostrictive strain of shunt reactor model without air gap and transformer with the same size are calculated by the orthogonal interpolation method. Considering the magnetostriction and Maxwell force, the vibrations of reactor and transformer core under different excitations are studied through the simulation software. Then, the vibrations of two model cores above are simulated considering the influence of Maxwell force alone. Compared with the core vibration under magnetostrictive and Maxwell forces, it is found that Maxwell fore is the main reason for the vibration of shunt reactor core without air gap pad, and its influence on the vibration of transformer core can be neglected. Finally, the vibration measurement platform for the two models is built, and the experimental results are in good agreement with the simulation results.
