同轴结构电极的介质阻挡放电研究
|
摘要
对管-管和线-管结构电极施加不同电压,测试其在不同电压下的放电电流及Lissajous图形,从传输电荷量、电流电压波形以及气隙电压变化等方面分析同轴结构电极的介质阻挡放电的放电机理。结果表明:在大气压敞开环境下,介质阻挡放电的管-管结构电极的气隙电压恒定,且远低于峰值电压,在放电过程中传输的电荷较多;而介质阻挡电晕放电的线-管结构电极的气隙电压变化较大,但与峰值电压相差不大,在放电过程中传输的电荷较少。
The discharge current and Lissajous images of tube-tube and wire-tube structure electrodes under different voltages were tested by applying different voltages on them, and the dielectric barrier discharge mechanism of coaxial structure electrodes were analyzed from the transmission charge amount,current and voltage waveforms, and discharge voltage variation of air gap. The results show that in open environment with atmospheric pressure, the air gap discharge voltage of tube-tube structure electrode dielectric barrier discharge is constant and much lower than the peak voltage, and there are more charges transmitted during discharge process. While the air gap discharge voltage of wire-tube structure electrode dielectric barrier corona discharge changes greatly and has little difference with the peak voltage, and there are little charges transmitted during discharge process.
