    摘 要:以螺環(huán)型沿面放電作為研究對象,利用有限元仿真軟件對沿面介質(zhì)阻擋放電裝置進(jìn)行靜電場的仿真分析,研究激勵電壓、高壓電極線徑、高壓電極間距( 螺距)、介質(zhì)厚度及介質(zhì)相對介電常數(shù)等對沿面介質(zhì)阻擋放電裝置靜電場的影響。仿真結(jié)果表明:在氣隙的同一位置,場強(qiáng)隨電壓的升高而線性增大,隨線徑的減小而非線性減小,隨介質(zhì)厚度的增加而非線性減小,隨相對介電常數(shù)的增大而非線性增大。選取電極線徑較小、介質(zhì)厚度薄、較大相對介電常數(shù)的介質(zhì),均可以降低放電起始電壓。

    Abstract: Taking a cylinder surface discharge reactor as the object, this paper simulated and analyzed the surface dielectric barrier discharge device by using finite element analyzing software. This paper researched on the influence of excitation voltage, high voltage electrode wire diameter and screw pitch, dielectric thickness and relative dielectric constant of dielectric etc on the static electrical field of surface dielectric barrier discharge device. The simulation results show that in the same position of air gap the electric field increases linearly with the increase of the applied voltage, reduces nonlinearly with the reduce of the wire diameter, reduces nonlinearly with the increase of the thickness of the dielectric and increases nonlinearly with the increase of relative dielectric constant. The selection of smaller diameter of the electrode, thicker dielectric or dielectric with larger relative dielectric constant could reduce discharge inception voltage.
    Key words: surface dielectric barrier discharge; discharge characteristic; electric field analysis; structural optimization
