摘要
研究了用于转基因的电晕电场在放电中针尖间距和针-板间距的变化对放电电流、放电输出功率和输出稳定性的影响.比较了多针-板与单针-板电晕放电的伏安特性.实验表明:针尖间距越大,电晕电流越大,当针尖间距大于20 mm时,电晕放电输出功率增长趋缓;当针尖间距为20 mm时,电晕放电可稳定输出较高的功率.针-板间距越小,电晕电流越大,当针-板间距为25 mm时,电晕放电输出功率最大.
The current characteristics,discharge energy,and output stability of corona discharge for multi-needle plates are experimentally researched with the change of spacing between needles, and spacing of needle and plate. The current-voltage characteristics of a multi-needle plate and a single-needle plate for negative corona discharge are compared. Experimental results show that the needle-tip spacing is bigger,the corona current is bigger. When the needle-tip spacing is bigger than 20 mm,the corona discharge output growth becomes slower,and when the needle-tip spacing is 20 mm, the corona discharge may output a stable high power. The spacing of needle and plate is smaller, the corona current is bigger. When the spacing of needle and plate is 25mm,the corona discharge output is biggest.
