| Abstract: | In order to explore the discharge characteristics of atmospheric pressure plasma jet (APPJ),the influence of power frequency and applied voltage on the discharge current,initial voltage,consumed power,average discharge power and jet length of helium jet was investigated by using a coaxial double ring electrode plasma jet device.The results showed that for the discharge images under the power frequencies of f=7.88 kHz,8.40 kHz and 8.90 kHz,the length of plasma jet increased first and then stabilized with the increase of voltage.The voltage-current relationship conformed to the characteristics of glow discharge.Under the same power frequency,with the increase of applied voltage,the number and amplitude of discharge current pulses increased,and the pulse curve distorted,while the consumed power of device and discharge power were not affected much. |
