Ultraviolet-based Detection System and Fault Location for High-voltage Discharge
MA Li-xi · Gaoya dianqi · 2014
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.
