Axial Vibrations Modal Analysis and Computation of Power Transformer Windings under Different Levels of Pre-Compression

摘要：

In this paper the discussions on the axial vibrations modal of power transformer windings under different levels of pre-compression through experiment and computation are presented. The axial vibrations modal of windings was investigated on the transformer model of windings both analytically and calculatedly, this proves that the changes of precompression on the windings have effects on their natural frequencies and derives their relation, it shows good agreement with experimental results, which provides the experimental and theoretical foundation for the design of transformer windings.
