摘要
带电检测及可见光观测均是在带电条件下掌控设备状态的手段,是对定检预试工作的重要补充。当前,成熟的带电检测技术包括红外检测、局放检测、X射线检测等,可见光观测技术普遍采用无人机、望远镜、照相机等设备。结合23条线路的检测实例,对红外、超声局放和可见光检测出的配电线路设备缺陷进行了总结,对缺陷原因进行了分析,可为同类工作提供参考。
Live detection and visible light observation are both means to control the state of equipment under live conditions,and are an important supplement to the pre-test work of regular inspections.Currently,mature live detection technologies include infrared detection,partial discharge detection,X-ray detection,etc.,and visible light observation technologies generally use drones,telescopes,cameras and other equipment for observation.Based on the detection examples of 23 lines,the defects of distribution line equipment detected by infrared,ultrasonic partial discharge and visible light are summarized,and the causes of the defects are analyzed,which can provide reference for similar work.
