摘要
为保证电力系统稳定运行,需要对变压器运行状态实施在线监测。对通过振动信号进行变压器在线监测方法现状进行综述,从振动产生机理因素、振动信号采集和影响因素、振动信号的分析与故障诊断三个方面进行了阐述和分析,并对振动分析法在变压器在线监测的发展趋势进行了展望,为振动法的进一步研究提供了思路。
To ensure the stable operation of power system,there is a need to implement online monitoring for transformers running status.This paper summarized the current situation of transformers online monitoring method for vibration signal,and expounded and analyzed from three aspects including vibration generation mechanism factors,vibration signal acquisition and influencing factors,vibration signal analysis and fault diagnosis,forecasting the development trend of transformer on-line monitoring of vibration analysis,which provides the thought for further studying the vibration manipulation.
