中文摘要:

理论实践表明,电力变压器表面振动信号特征分析是振动法分析电力变压器状态的一个重要基础,振动信号特征可以用来分析判断其绕组和铁芯的工作状态。本文分析了现场采集的电力变压器表面振动信号的功率特征以及功率与负载电流的关系,为振动法分析电力变压器运行状态提供参考。

英文摘要:

Theoretical analysis and practice experience has shown that, it is an important foundation for the judgement of the power transformer’s state to analyze the characteristics of vibration signal on power transformer surface and the characteristics of vibration signal can be used to analyze and judge the work state of the winding and iron core. Power spectrum of surface vibration signal of the running power transformer and the relationship between power spectrum and load current is analyzed. It can provide some reference for the power transformer vibration analysis.
