超声表面波法在GIS设备表面裂纹缺陷检测中的应用

Application of Ultrasonic Wave Method in the Detection of Flaw Defect on the Surface of GIS Equipment

GIS设备采用金属封闭、SF6气体绝缘结构,故筒体结构的密封性对于设备的安全运行具有重要意义。应用超声表面波法和渗透检测对GIS设备表面裂纹缺陷进行危险性评估,在缺陷发展为贯穿性裂纹前进行预警,保障GIS设备的稳定运行。

The tightness of the GIS equipment tubular construction is important to safe operation of the GIS equipment. Ultrasonic wave method and penetration detection were used to detect flaw defect on the surface of the GIS equipment and the risk was evaluated to give early warning for the development of defect into through - crack and to ensure safe operation of the GIS equipment.
