变压器有载分接开关机械性能的在线监测与故障诊断技术

Development in Condition Monitoring and Fault Diagnostics of Mechanical Performance of Power Transformer On-load Tap Changers

对当前电力变压器有载调压分接开关机械性能的在线监测与故障诊断技术,进行了综述和分析,指出需要重点解决的关键问题与难点。结合作者目前的研究工作,给出了新的研究策略,以期应用于有载分接开关的状态监测中,提高其机械故障诊断的有效性和灵敏度。

The recent advancement in condition monitoring and fault diagnostics of the mechanical performance of power transformer on-load tap changers （OLTC） was reviewed and analysed, and some key issues and difficulties associated with it were pointed out. Based on the current research work of the authors, new research strategy was proposed with a view to be further applied in condition monitoring of OLTC, and hence ameliorate the effectiveness and sensitivity of mechanical fault diagnosis.
