摘要
变电站和输电线路中,存在大量如电气设备接头、电缆接头处这样时导电连接部位,由于连接件的磨损、腐蚀、氧化、设计等问题,可能造成设备过热,应用红外线检测技术可直接判断设备发热情况。文章指出了带电设备外部缺陷的特点,分析了影响带电设备外部缺陷红外检测的因素,论述了红外线检测技术在发热缺陷判别中的具体应用,同时也指出了红外线技术有着广阔的发展前景。
A large numbers of conductive connecting parts exist in substation and transmission line, such as electric installation joint and cable joint; besides, some problems such as abrasion, erosion, oxidation and design of connecting part may lead to equipment superheat, thus the infrared inspection technology can directly estimate heating situation of equipment. The paper indicates the external defect character of charging equipment, and analyzes factors that influence external defect infrared inspection of charging equipment, as well as expounds the detailed application of infrared inspection technology in heating defect estimation, also it indicates the wide developing foreground of infrared inspection technology.
