摘要

研究了变压器振动信号的产生原理和希尔伯特黄变换原理,基于希尔伯特黄变换分析了变压器振动信号的故障特征,边际谱结果表明,变压器不同故障状态,其200Hz、300Hz和400Hz的边际谱均会有所变化.

Abstract

In this paper,the generation principle of the transformer vibration signal and Hilbert yellow transforma-tion are studied.Based on the fault characteristics of the transformer vibration signal based on the Hilbert yellow transformation,the marginal spectrum results show that the marginal spectrum of 200Hz,300Hz and 400Hz will change in different fault states.
