影响介质阻挡放电的因素

针对影响介质阻挡放电的因素较多,理论还不完全成熟的现状,通过试验研究了影响介质阻挡放电的部分因素,如施加电压的幅值、极板间气隙的间距、不同介电常数的阻挡介质、不同厚度的同一种介质、网眼大小不同的丝网、不同结构形式的极板结构。试验发现电极结构以及阻挡介质的材料对放电影响较大,采用针板电极及电阻率高的阻挡介质容易形成稳定的放电。该研究可供下一步进行其它影响因素的试验和理论研究及应用参考。

Experimental Study of Factors Affecting Dielectric-barrier Discharge

The influences of the applied voltage,the gas gap distance,and the thickness,dielectric permittivity of the barrier,different net and different structure electrical pole on the discharge characteristics are studied.The electrical characteristics under different conditions and the influencing factors were analyzed.The results show that the value of power dissipated increases with the increasing of applied voltage and dielectric permittivity of the barrier,and decrease with the increasing of gas gap distance and the thickness of barrier.It founds that the electrical pole structure and material of the dielectric barrier are imprtant effect to produce discharge,the nddle-plate and high resistivity barrier will produce stable discharge.The experimental results will be useful for the next research work.
