同轴圆柱介质阻挡放电半周不对称等效负载模型

同轴圆柱反应器常用于发生介质阻挡放电。实验表明在大气环境的放电中,仅单侧电极有介质的同轴圆柱反应器,放电特性不同于两侧电极都有介质的反应器。前者正反半周放电机理不同,等效电气参数区别很大,不能再用传统的非线性箝位模型作为其等效负载模型。针对此类反应器,提出一种新的半周不对称分段等效模型,并给出了基于李萨如图形的模型参数计算方法,使之能更精确地描述此类介质阻挡放电反应器的电气特性。

Half-Cycle Asymmetric Model of Dielectric Barrier Discharge with Coaxial Cylinder Reactor

Coaxial cylindrical reactors are commonly used for dielectric barrier discharges.Experiments show that in the discharge in the atmosphere,the coaxial cylindrical reactor with only one side electrode having a dielectric has a discharge characteristic different from that of a reactor having a dielectric on both sides of the electrode.The former has different forward and reverse half-cycle discharge mechanisms,and the equivalent electrical parameters are very different.Traditional nonlinear clamping models can no longer be used as their equivalent load models.Therefore,this paper proposes a new half-cycle asymmetric piecewise equivalent model for this type of reactor,and offers a model parameter calculation method based on the Lissajous figure,so that it can more accurately describe the DBD reactor electrical characteristics.
