摘要
利用输电线路和变电站设备电晕可以进行缺陷定位、分析判断绝缘的真实状况。描述了基于日盲滤光片和MCP探测器研制的电晕紫外成像仪,并与可见光摄像机进行同视场检测,实现了电晕的高灵敏检测和定位。为验证紫外成像检测的性能,利用高压尖端放电设备进行了不同放电强度的实验以及电晕放电的现场检测,结果表明:研制的电晕紫外成像仪能够用于高压电晕的检测和故障定位。
Transmission line and equipment corona of transformer station can be used to locate defect and analyze real situation of insulation. A UV imager based on solar blind filter and MCP detector was described. This instrument worked with visible light video camera in the same visual field and high sensitivity detection and location for corona were realized. In order to test the performance of UV imaging detection high voltage point discharge equipment was used in experiments of different discharge intensities and onsite corona discharge detection. Results showed that the developed UV corona imager could be applied in detecting high voltage corona and locating fault.
