电力变压器振动噪声的多物理场耦合分析
Multi-physical Field Coupling Analysis on Vibration Noise of Power Transformer
摘要
Abstract
Modeling simulation method is used in this paper for transient calculation and research on production, propagation and distribution of vibration noise of the power transformer. By means of theoretical analysis on production mechanism of vibration noise, it determines correlation between characteristic of vibration noise of the power transformer and other influencing factors. It adopts multi-physical field finite element analysis software to build a 3D entity model for the power transformer for multi-physical field coupling simulating calculation on comprehensive electromagnetic field, structural force field and pressure field. Corresponding results show space distribution and frequency characteristic of vibration noise signal of 3D power transformer in each solution domain. Comparison result with actual measured noise data under the same working condition indicates this modeling method and analysis calculation has higher veracity to supplement important and effective means for studying vibration noise of the power transformer.关键词
