基于声音的变压器故障识别

Transformer Fault Recognition Based on Sound

在电网中,电力变压器是一种非常重要的能量传输和转换装置,其运行稳定性和可靠性对整个电网具有很大的影响,所以对变压器的运行状态进行准确评估,有效地保持电力变压器的运行稳定性并提高维护水平具有重要的意义。在电力变压器工作时,机械振动会发出声音,且具有一定的规律性,所以提出了一种根据变压器声音判断其运行状态的方法。介绍了变压器机械振动产生的声音的特征,以及对正常状态下和非正常状态下声音的研究,进一步提取更多有效的声音,为变压器故障判断提供了辅助方法。

In the power grid,the power transformer is a very important energy transmission and conversion device,and its operational stability and reliability have a great impact on the entire power grid.Therefore,it is of great significance to accurately evaluate the operating status of the transformer,effectively maintain the operating stability of the power transformer and improve the maintenance level.When the power transformer is working,the mechanical vibration will make a sound,and it has a certain regularity.Therefore,a method for judging the operating status of the transformer based on the sound of the transformer is proposed.The characteristics of sound produced by mechanical vibration of transformer are introduced.The research on the sound under normal and abnormal conditions can further extract more effective sound,which provides an auxiliary method for transformer fault diagnosis.
