【摘要】 研究了脉冲电源以脉冲电晕放电方式向反应器注入能量时的时间不均匀特性,阐述有效时间、有效平均功率等概念后分析了单针型针板式反应器中脉冲电晕放电功率与电流保持一致的时间特性。实验测得脉冲电源的单次脉冲时间为0.01～0.1s,平均功率为5～30W;有效时间约10μs,有效平均功率为15～60kW,比平均功率大3个数量级。有效时间内脉冲电晕放电过程以较大功率向反应器注入能量,有效平均功率是表征有效时间内脉冲电晕能量有效注入过程的平均量,这是脉冲电晕放电过程中较普遍存在的一种特征。更多还原

【Abstract】 In process of pulse corona discharge, the asymmetric time characteristics in injection of energy from pulse power supply to reactor are studied in this article. The concepts of effective time and effective average power are defined and studied in a needle plate reactor with single needle. The consistent characteristics of pulse power and pulse current in time are also studied. Single pulse time distribution is from 0.01 s to 0.1 s. Average power distribution is from 5 W to 30 W. Effective time is about 10 μs. Effective average power distribution is from 15 kW to 60 kW. The effective average power is about 10~3 times of average power. And in effective time, energy injected into reactor is with huge power in course of pulse corona discharge. Effective average power is a kind of parameter to denote the process of energy injection in pulse corona discharge. It is a kind of ubiquitous characteristic in course of pulse discharge studied in this article.更多还原
