摘　　要：随着状态检修工作的全面实施,GIS设备带电检测的重要性日趋突出。GIS设备局放超声检测法因抗干扰性强、操作方便,适合现场使用。介绍在某GIS厂家新产品出厂检测中,笔者采用超声诊断技术成功检测出1起内部缺陷。With the overall implementation of the condition-based maintenance, the GIS hot-line test has becomed more and more important. Compared with other kinds of partial discharge detection methods such as electrical method, optical method etc. , ultrasound method is more effective in anti-interference and operation conveniency and more suitable for the field work. An internal defect was detected successfully by ultrasound diagnostic technology in factory inspection of new products.
