【摘要】 通过建立介质阻挡放电试验系统,采用Q-V Lissajous图形法研究了激励电压峰值VP-P、放电气隙lg对介质阻挡放电主要参量的影响。试验结果表明:增大VP-P、lg可提高介质阻挡放电的放电功率P;固定lg时,电介质层等效电容Cd随VP-P的增大而增大,放电间隙等效电容Cg随VP-P的增大而减小,VP-P对等效总电容C的影响不大;C、Cd、Cg均随lg增大而减小;电荷传输量Q、气隙等效电场强度Eg随VP-P的增大而升高,随lg的增大而降低。更多还原

【Abstract】 Through establishing DBD(dielectric barrier discharge) experiment system and Q-V Lissajous figure method,the effects of applied peak voltage(VP-P)and discharge gap(lg) on the main parameters of DSP are studied.The results show that increasing VP-P and lg can effectively enhance DBD power(P);the effect of VP-P on the total equivalent capacitance(C) is little under certain lg,the dielectric equivalent capacitance(Cd) increases and the equivalent capacitance of the discharge gap(Cg) decreases with the increasing VP-P;C,Cd,and Cg all decrease with the increasing lg;the charge transfer value(Q)and effective electric field of the discharge gap(Eg) increase with the increase of VP-P,but decrease with the increase of lg.更多还原
