GIS设备机械缺陷振动信号特征分析技术研究
Research on Characteristics Analysis Technology of Vibration Signal of Mechanical Defects in GIS Equipment
摘要
Abstract
The detection of mechanical vibration defects is one of the effective means to ensure safe operation of GIS equipment.However,there is still lack of systematic research on the vibration of mechanical defects for various com-ponents of GIS equipment.In this paper,one highly sensitive detection device for the vibration state of GIS equip-ment is developed,a high-voltage and high-current test platform for mechanical defects of GIS equipment,which simulates 5 kinds of typical defects,is set up,and study on the vibration signal characteristics test of GIS equipment is performed.The test results show that in case the load current remains unchanged,the vibration signal hardly changes with the variation of voltage.Under the action of same voltage,the vibration signal waveform remains basi-cally unchanged,and the amplitude of the vibration signal increases with the increase of the load current.While,in the case of mechanical defects,the main frequency spectrum of the vibration signal is 100 Hz,with more high fre-quency components superimposed,and vibration signals of different defects show different frequency and amplitude characteristics.The frequency band energy characteristic analysis method based on Fourier analysis is adopted to construct vibration feature fingerprint database for typical defects.The results in this paper can be used for mechani-cal defect detection and type identification of GIS equipment as well as the guidance of maintenance work on site.关键词
