Research on Space Electrostatic Discharge Detection Technology Based on Optical Fiber Sensing

Abstract

Aiming at the electrostatic discharge characteristics of space high-voltage power system, a discharge detection technology based on fluorescent fiber is proposed. The optical signal generated by the electrostatic discharge is received by the fluorescent fiber, and then converted into an electrical signal through photoelectric conversion to realize the electrostatic discharge detection. The electrostatic discharge ground experimental system was built, and the analysis of different design parameters of the sensor through experiment was carried out, and the optimal design parameters were selected. Based on it, the electrostatic discharge detection experiment by fluorescent fiber sensor was carried out. The experimental results show that the developed fluorescent optical fiber sensor can quickly and accurately detect the electrostatic discharge signal.
