采用双水电极介质阻挡放电装置,观察了60kPa气压下氩气的放电情况,并利用Matlab软件对放电图像中的电场和电势分布进行仿真模拟,从而对相邻两沿面放电之间的影响进行研究。在空气-氩气介质阻挡放电中,随着电压的升高,放电区域内放电丝的数量从四个增加到五个,放电丝周围的沿面放电区域也发生了巨大变化。为了对影响沿面放电分布的因素进行更深入的研究,对电流波形图中放电脉冲进行积分,从而对放电区域的电势和电场线进行了模拟。本文将会对相邻沿面放电之间的相互影响提供一个更深入的理解
The mutual influence between the adjacent surface discharges is investigated in a dielectric barrier discharge (DBD) system by using analogue simulation for the first time. In air-argon dielectric barrier discharge, the discharge undergoes four filaments-five filaments and the shape of surface discharge also changed with the applied voltage increases . In addition, the electric field distribution and electric potential distribution is established to conduct simulation in the locations of the corresponding filaments.
