两起典型红外发热缺陷案例分析及处理

2 Case Studies for Defects Inspection Using IR Temperature Measurement Technology

红外测温技术是电力设备状态检修、带电检测的重要技术手段,具有不接触、不取样、不停电且准确、便捷、直观的优点。其中,接头接触不良、螺栓紧固不牢是红外测温发现的主要问题,然而目前对此类缺陷普遍缺乏重视,难以及时消缺。文中根据2起典型案例分析介绍此类缺陷的产生原因以及处理方法,为此类缺陷的检修工作提供参考。

As one important defects inspection technique, IR temperature measurement technology has the advantages of no contact, no sampling, no blackout, convenience, intuition and accuracy. The main problem found by IR temperature measurement technology is poor contact joints which is not paid enough attention to. In this paper, 2 case studies are provided with reason analysis and countermeasures for poor contact joints.
