Optimization of Transformer Vibration Measuring Points Based on Finite Element Analysis
摘要
Abstract
In order to study reasonable selection methods for measuring points in transformer vibration testing,the finite ele-ment analysis method was used for analysis on modal and harmonic response of the transformer. By means of finite element simulation calculation on vibration signals of one 500 kVA and one 10 kV/400 A oil immersed transformers,surface vibra-tion states of transformer oil tanks were compared so as to search the optimal position of the measuring point and summarize general principle for measuring point configuration for transformer vibration testing. Field test result indicates this method is feasible for evaluation and study on transformer state.关键词
