基于振动监测的 OLTC 运行状态分析方法研究

摘要

介绍对 OLTC 振动监测数据分析应用应区分不同机械结构的 OLTC,其次基于数学方法对监测数据特征量的提取分析应用中应滤除本体运行产生的噪声影响,进一步通过监测信号特征波形的比较分析,关注每个 OLTC 调档操作中存在的特征量,判断 OLTC 的运行状态正常有否,诊断其不同类型的故障。%This paper discuss that data analysis and use should distinguish the different mechanical structure of OLTC, and monito-ring data characteristics extraction and analysis based on mathematical methods should filter out the noise impact of ontology, and further comparative analyse the monitoring signal waveform, pay close attention to the characteristics in each OLTC shifting gear op-eration, the running state of OLTC is normal or not, and whether there is a fault can be judged.
