摘要：

Surface flashover is one of the main forms of electrostatic discharge on spacecraft surface, and is essential for safe operation of the spacecraft.In this paper, based on the Second Electron Emission Avalanche (SEEA) model, the surface flashover characteristics of spacecraft insulating materials were analyzed theoretically, and then the surface flashover characteristics of kapton in low pressure environment were studied by using the spacecraft surface charging simulation system.The law of flashover voltage in low pressure environment was explained from the three aspects of desorption gas, roughness and chemical change.The results show that in low pressure environment, with the decrease of pressure, the flashover voltage of kapton decreased firstly, then increased, and then stabilized.When the pressure and the number of flashover discharge were constant, the flashover voltage of kapton increased with the increase of electrode spacing, and the average flashover field intensity decreased.When the pressure and electrode spacing remain constant, the flashover voltage of kapton increased first and then became stable with the increase of the number of discharges. © 2022 AAAS Press of Chinese Society of Aeronautics and Astronautics.
