如何选择振动检测测点位置,对于变压器振动检测十分重要。根据振动检测测点有效性选择原则的分析,利用开发的测试设备,在1台220 kV变压器上进行定频变电流试验。通过对变压器振动检测测点位置选择进行的一系列试验数据的分析,最终总结出测点布置选择原则。“,”The selection of measuring points is very important for the vibration detection of transformers.Based on the effective selection principle and developed detection equipment,a series of experiments were conducted on one 220 kV transformer with fixed-frequency and variable current.Finally,according to the analysis of experiment results,the principles are summarized for measuring point selection.
