摘要

电力变压器铁芯的振动主要是由硅钢片的磁致伸缩和铁芯片与接头之间附加的电磁力共同作用引起的。开展变压器铁心振动特性研究，对提高变压器运行可靠性具有重要意义。本文首先对三相三柱变压器铁心进行振动试验，探讨其固有振动特性。其次，建立有限元仿真模型，利用欧拉-伯努利方程对杨氏模量进行修正;最后，对三相三柱变压器铁心的振动特性进行了实验研究，得到了铁心表面的振动分布规律。

Investigation of the Core's Vibration Characteristics of a Distribution Transformer

The vibration of the iron core of the power transformer is mainly caused by the combined action of the magnetostriction of the silicon steel sheets and the additional electromagnetic force between the iron core sheets and the joints. It is of great significance to carry out research on the vibration characteristics of transformer cores to improve the reliability of transformer operation. In this paper, the vibration test of the three-phase three-column transformer core is firstly conducted to explore its natural vibration characteristics. Secondly, the finite element simulation model is established and the Young's modulus is corrected by Euler Bernoulli equation. Finally, the vibration characteristics of the three-phase three-column transformer core are experimentally studied to obtain the vibration distribution law on the surface of the core.
