摘要
本文利用一个能产生稳定的离子浓度的独立的离子源,在被研究的间隙中形成一定的离子背景,用升降法观测了正、负背景离子对棒-板间隙百分之五十击穿电压的影响;测量了正、负背景离子对正棒-板间隙伏秒特性的影响;用截波静止摄影法观测了正、负离子背景对放电通道的形态及先导发展速度的影响。文中对这些观测结果的物理机理给予了解释。
The influence of ions in the background on the impulse discharge characteristics in air is studied. In order to form a background with a certain ion density in the gap, an independent ion generator was used. The effect of positive and negative ions on the V50 of the rod-plane gap and that on the v-t curve were measured. The effect of positive and negative background ions on the leader velocity and pattern of discharge channel were also observed by the still camera and chopped wave. The mechanism of effects of background ions on discharge is tentatively explained.
