摘　　要：变电站GIS设备是承压设备,其结构复杂、内部充有SF6绝缘气体,GIS设备壳体的生产执行国家压力容器生产制造规程,其壳体的焊接质量是保证GIS设备安全运行的基础。通过研究确定涡流检测方法,实现了GIS设备筒体焊缝的现场带电检测,并在现场得到成功应用。Substation GIS equipment is the pressure equipment, its structure is complex , the internal filled with SF6 insulation gas, the GIS equipment＇ s shell implementing national pressure vessel manufacturing procedures, so the shell＇ s welding quality is the basis to ensure the safe operation of GIS equipment. Through testing, the paper deter- mins eddy current detection method, and realizes on-line detection of tube weld of GIS equipment, and has been suc- cessfully applied in the field.
