为了改善介质阻挡放电分布形成工业水平均匀放电,研制了旋转电极介质阻挡放电装置,在高频和低频下形成带状放电分布。通过拍摄50Hz半个周期内放电照片,发现放电在半个周期内形成了带状轨迹。这说明在半个周期内,放电残留物随气流流动为下游放电提供初电子,有利于形成带状轨迹分布。在工频条件下,拍摄了不同转速下的放电照片,发现随着转速增加,带状区域扩大,放电分布变得更均匀。上述现象及初步计算分析说明利用电极旋转带动放电残留物与壁电荷发生相对位移改变放电分布是成功的,为下一步实现工业应用水平上的均匀放电提供了可能性。

The banded dielectric barrier discharge excited by high and low frequency voltage was obtained in the rotating electrode equipment. To present the formation of the banded dielectric barrier discharge, we analyzed the discharge image excited by 50 Hz. In the half voltage cycle, the remains moving with the neutral gas flow could supply the seed electrons for the discharge in the downstream. On the voltage reversal, however, the surface charges provided the seed electrons for the discharge. The relationship between the discharge distribution and rotating rate was expressed. Moreover, with the increase of the rotating rate, the banded discharge region excited by 50 Hz was expanding, indicating that the rotating electrode could change the discharge distribution and might form homogeneous discharge for the industrial applications.
