【Abstract】 In this paper we studied the effects of the space charge produced by a corona streamer discharge in rod-plane long air gap, submitted to a positive switching impulse. The process and structure of discharge in long air gap have been clarified further by the aid of Lichtenberg figure technique, A previous model of space eharge effects is corrected. With the help of computer and our new model, the mathematieal models of corona streamer discharge and the characteristics of leader inception have been set up. For the rod-plane gaps with 40cm and 80cm gas-lengths as well as with the wave front between l5-600μs, the characteristics of the discharge have been calculated. The results of calculation coincide with the exp(?)rimental values. It is proved that the new model of space charge effect is suitable and practical.更多还原
