Ultraviolet-based Detection System and Fault Location for High-voltage Discharge

针对高压设备电晕放电和故障点定位的问题,设计了一种基于紫外电晕技术的高压放电检测系统,介绍了系统的主要设备及功能。同时,研究出一套基于滤光片切换的单通道滤光成像法,通过该套方法可使紫外与可见光两种光谱分别经过系统光路,完成最后的图像采集与融合,在单通道光路结构下达到电晕定位的目的。通过成像实验,证明该方法的可行性。

Aiming at corona discharge and fault location in high-voltage apparatus,a high-voltage discharge detection system based on ultraviolet（UV）corona technology was designed. The main devices in the system and their functions are introduced in this paper. Moreover,a single-channel imaging method based on filter switching was proposed, in which UV spectrum and visible light spectrum individually go through the system＇s optical tunnel to complete the final image acquisition and fusion, so as to achieve corona location via the single-channel optical structure. Imaging experiment shows the feasibility of the present high-voltage discharge detection system and single-channel imaging method.
