【摘要】 为了探索适合特高压GIL设备的现场交接验收及机械缺陷检测方法，文中对传统GIL设备交接验收时的交流耐压试验、投运前绝缘性能考核试验及局部放电试验进行了改进，采用与振动检测法相结合的方式。在此基础上研制了GIL综合试验与机械缺陷检测分析平台，并融合了出厂试验数据、历史运行数据、常规检测数据及改进后的交接试验数据进行多源多参量分析。解决了传统方法无法判别GIL设备微小机械缺陷的问题，使运维人员能够更加全面的掌握GIL设备的状态。现场应用实例表明，该平台能切实提升特高压GIL设备的现场交接验收效率及规范性，降低GIL存在机械损伤的危险性，进而实现设备精准运维。更多还原

【Abstract】 For exploring the on-site hand-over acceptance and mechanical defect detection methods suitable for UHV GIL equipment,in this paper the AC withstand voltage test,insulation performance assessment test and partial discharge test before operation during the hand-over acceptance of the traditional GIL equipment are improved,and the combination with vibration detection method is adopted.On this basis,a comprehensive test and mechanical defect detection and analysis platform for GIL is developed,and the delivery test data,historical operation data,conventional test data and improved handover test data for multi-source and multi-parameter analysis are integrated. It solves the problem that traditional method cannot identify the minor mechanical defects of GIL equipment,and enables operation and maintenance personnel to master comprehensively the state of GIL equipment. Field application examples show that the platform can effectively improve the efficiency and standardization of the on-site handover and acceptance of ultra-high voltage GIL equipment,reduce the risk of mechanical damage to GIL,and thus realize accurate operation and maintenance of the equipment.更多还原
