摘要
Abstract
Live detection technology plays an increasingly important role in state detection of power transmission and transformation equipment.To better conduct live detection of electrical equipment,this paper introduces the principle of ultrasonic detection technology and the typical atlas of common particle defects.The detection and diagnosis of the particles on the isolated basin-insulator in a 500 kV GIS substation are conducted to obtain an atlas,which is quite different from the typical atlas.According to the obtained atlas,the detection process of particle defects and the features of ultrasonic and UHF signals are concluded.Furthermore,a risk evaluation method is proposed,and the diagnostic criteria of GIS particle defects is improved.This research may provide a reference for detection and diagnosis of particle defects,especially the particle defects on the non-metallic parts,such as basin-insulator.关键词
