针-板电极负电晕放电下离子分布状态的影响因素
Influencing Factors of the Ions Distribution Under the Needle to Plate Negative Corona Discharge
摘要
Abstract
In order to study the effect of influencing factors on ions in the process of corona discharge,we used a needle-to-plate corona discharge device,by changing the size of the discharge space,to measure the current distribution in different area of the plate on different discharge voltage.Through the simulation of electric field and ionic wind,we analyzed the relationship between electric field intensity,ion wind,and ions interaction in the process of negative corona discharge.The results show that,in the process of needle-to-plate corona discharge,the state of ions motion,the strength of discharge electric field,and the distribution of ionic wind interfer with each other,finally the distribution of ions in the electric field is formed.The electric field is the main factor affecting the ions trajectory,but with the weakening of the electric field,the ionic wind field gradually forms,the ionic wind will carry part of the ions moving together,when the flow field form of ionic wind is the main factors affecting the ions motion.By analyzing the motion of ions in the electric field,the theoretical support is provided for solving the interaction between ions and electric field in discharge electric field.关键词
