摘要
本文通过分析变压器正常状态和故障状态下振动信号特征,提出频率集中度和振动平稳性指标实现对变压器状态监测,并利用互信息方法确立影响因子与振动信号特征参量关系,实现了变压器故障诊断及定位。
This paper analyzes the characteristics of the vibration signal in the normal state and the fault state of the transformer, proposes the frequency concentration and vibration stability indicators to realize the monitoring of the transformer state, and uses the mutual information method to establish the relationship between the influence factor and the vibration signal characteristic parameters, and realizes the transformer fault diagnosis and Fault location.
