摘要：
The air discharge experimental platform is built and the simulation model is constructed. Air streamer discharge of non-uniform electric field under low temperature and sub atmospheric pressure is studied through experiment and simulation. The results show that when the reduced electric field E/N is the same, the altitude is negatively correlated with the number of streamer bifurcation, streamer propagation velocity, current peak and current decay time, and positively correlated with streamer radius, but the streamer propagation velocity and current obtained by simulation are slightly different from the actual ones. The existence of pre-ionization region leads to different discharge morphology under needle-plate and needle-needle electrode. With the increase of square wave voltage frequency, the dependence of secondary discharge channel on primary discharge channel increases gradually. With the increase of square wave voltage duty cycle, the secondary discharge channel is only reflected at the tail of the primary discharge channel. ©2023 Chin.Soc.for Elec.Eng.
