为了实现紫外光和可见光对电力设备的电晕放电情况进行复合图像检测,提出了采用双光路结构的光信号处理方法。设计并研制了基于可见反射式光路结构的紫外可见双光路电晕放电检测系统。该系统解决了紫外光成像与可见光成像能量差异大导致图像配准困难的问题。试验结果表明,该系统能实现电力设备电晕放电情况的准确探测及定位。

In order to realize the combined image test of corona discharge of electrical equipment by ultraviolet and visible light, the dual optical path structure based optical signal processing method are proposed. The ultraviolet and visible dual-light path corona discharge test system based on the reflective optical path structure is designed and developed, which solve the image registration problem cause by the big difference of image energy between ultraviolet light and visible light. Test results show that the system can realize the accurate detection and location of corona discharge of electrical equipment.
