摘要
Abstract
Optical detection of partial discharge (PD) is one of the effective ways to detect partial discharge inside power equipment, and it is also an important research direction in PD detection technology. In this paper, the model of gas-insulated switchgear (GIS) and PD defect model are established. The propagation characteristics of PD optical signals in GIS are observed and analyzed by optical simulation. The simulation results show that the optical signal propagation of different defect models has similar trends and different attenuation ranges. Different types of light spots are left on the detection surface. When the propagation distance reaches about 1 meter, the detected radiant flux is less than 10％ of the original radiant flux of the defect model. The simulation results are helpful to understand the propagation characteristics of the PD optical signal, and also provide reference for the design of related detection devices in power equipment.关键词
