不停电检测技术在变电站设备带电水冲洗中的应用

介绍了紫外检测、红外热像检测等带电检测技术和泄漏电流在线监测技术在变电站设备带电水冲洗过程中的应用情况;通过紫外图谱、红外热像图及泄漏电流监测值的对比,分析了变电站设备带电水冲洗技术的安全性和有效性。应用结果表明,利用带电检测及在线监测技术可实现带电水冲洗的全过程监控,实时监测被冲洗设备的外绝缘状态,建议在变电站设备带电水冲洗过程中推广应用此类检测技术手段。

Application of Online Monitoring and Live Test Technologies in Live Water Washing for Substation Equipment

Introduction was made to the application situation of ultraviolet test, infrared thermography test etc live test technologies and leakage current online monitoring test technology in live water washing process of substation equipment. Via comparison of ultraviolet image, infrared thermal image and leakage current measured values, this paper analyzed the safety and validity of live water washing technology of substation equipment. Application result shows that using live test and online monitoring technologies can realize whole journey online monitoring of live water washing and detect the external insulation state of equipment being washed in real time. This paper suggested popularizing application of such test technical means in live water washing process of substation equipment.
