Factor Analysis For The Influence Of Medium Characteristic On Dielectric Barrier Glow Discharge

Based on the physical and material property of the medium, this paper study the factors which influence the discharge density of the reactor. Using the multi-clip boards and changing the number of the board-shaped electricala medium, the flucuration of the discharge density is measured by the oscillograph. And then, the discharge power, the air field density and the strength of the capacitance are also calculated by using it. It is showed that the deduction of the dielectirc barried flow discharge can be still used in the condition the tabular dielectric medium. The research study the discharge condition in the situation of changing the diameter of the granular medium, the dielectric constant and its arragement, and the resulte has been analysed by using the Lisaru graphic. The discharge density and the discharge power in the corporative action of the plate and granular dielectric medium was also analysed.In the comparement of the result using diffent plate number, it is discovered that, in the same voltage, without considering other factors , the capacitance of the reator will rise with the increase of the plate number. The discharge strength and the power are also rised with it. There is no obvious difference in the halo voltage by using the single plate compared with the multi-clips boards, while, the breakdown soltage is less than multi-clip boards.The discharging current strength, different material of the granular discharge medium and the dielectric constant are proportional to specific surface area. The discharge made no changes when the number of layers in a concentrated winding of granular dielectric medium were less. And the influence of number of layers need to be studied.The dielectric constant, permittivity of tabular dielectric had no influence to discharging in the reation of both two dielectrics. In the experiment using the polytef added the granular medium, the maximum discharge electricity is 106μA, the maxium electricity without granular partical is 15μA. The dielectric constant of the plate medium also has a positive correlationship with the effect of the discharge. As for it, the chosen of the granular and plate medium of large dielectric constant is needed in order to get the ideal discharge strength.
