Study of Vibration Sensitive Areas on 500kv Power Transformer Tank
This paper aims to study the sensitivity of 500kv power transformer tank to winding vibrations. Through full analyses of winding vibration characteristics, tank mechanical characteristics and vibration differences in different positions on tank surface, the authors propose some evaluation criteria and principles on vibration measuring positions on the tank. Based on the principles, the relevant experimental studies and analyses are conducted for 500kV power transformers with a single phase structure. Besides, the methods are also proposed for selecting sensitive measuring positions that can effectively reflect the winding vibrations of 500kV power transformers. The study results show that the principles and methods proposed will provide good foundations and support for on-line condition monitoring and fault diagnoses of power transformers.
