摘　　要：紫外成像技术具有测试距离远、不需停电、可连续测试等优点,在电力设备外绝缘故障检测中得到了广泛应用。但由于紫外信号无法穿透设备外壳,因此目前对于设备内绝缘的紫外诊断手段尚缺乏研究。本文将传统试验技术与最新紫外检测手段相结合,在使用传统方法进行设备绝缘状态评估的基础上结合设备内部不同放电程度的紫外图谱对缺陷情况进行诊断,取得了很好的效果,扩展了紫外成像技术在电力设备故障诊断中的应用。Ultraviolet imaging possesses the following advantages: far distance? short outage time, continuous testing, have been extensively used in fault diagnosis, but ultraviolet light can't penetrate the equipment shell , so relevant researches lag behind internal insulation fault diagnosis. In this paper, combines the traditional high voltage test technique and ultraviolet imagery means, use the traditional method to condition evaluation, then use ultraviolet imagery means to fault diagnosis. It is very good and useful.
