摘要
分析了电力变压器噪声的的产生原因和特点以及近场声全息技术在噪声源识别上的优势.制定了电力变压器噪声源识别的基本技术流程,开发了测试数据的预处理和后处理软件.实验证明系统能够满足变压器噪声源识别的需求.
Abstract
This paper analyzes the characteristics and mechanism of transformer noise,and the advantages of near acoustic holography (NAH) in identifying noise sources.An identification process of transformer noise sources has been defined,including data prc-process module and NAH process module.Test results show that the system can meet the requirements of the transformer noise sources identification.
