摘要 铁心磁致伸缩效应与绕组受力是高压并联电抗器振动的主要原因。基于晶粒取向型硅钢片的磁致伸缩产生机理,将铁心磁致伸缩本质模型及Jiles磁致伸缩模型与实验数据进行对比分析,结果表明本质计算模型能准确地模拟硅钢片的磁致伸缩应变。在确定磁致伸缩本质计算模型有效性的基础上,用多物理场仿真软件COMSOL建立了一台额定电压为10.5 kV、容量为30 000 kvar高压并联电抗器本体结构的振动计算模型。从磁-机械场耦合的角度分析高压并联电抗器铁心振动与绕组受力特性,结果表明绕组受力很大,引起的振动不容忽略。同时研究了具有不同杨氏模量的气隙垫块对并联电抗器铁心振动的影响,杨氏模量越大的气隙垫块对高压并联电抗器的振动抑制效果越好。

Abstract:The main reason for the vibration of the high voltage shunt reactor core is the magnetostrictive effect and the winding deformation. This paper analyzes the magnetostrictive mechanism of the grain oriented silicon steel sheet. The comparison of the essence of magnetostrictive model and Jiles calculation model with the experimental data is analyzed, the results show that the essence of magnetostrictive model can better simulate the magnetostriction strain. The multi-physics simulation software COMSOL is used to establish the vibration model of a high voltage shunt reactor body structure with 10.5 kV rated voltage and capacity of 30 000 kvar. The shunt reactor core vibration and winding force characteristics are analyzed from the perspective of magneto-mechanical coupling, the results show that the force of the winding is very large, and the vibration can not be ignored. And the effect of reducing vibration of core vibration by using the air gap pad of different Young's modulus is studied, the air gap pad with high young's modulus can well reduce the vibration of the shunt reactor.
