Characteristics of Breakdown Voltage at a Narrow Gap in a Non-thermal Plasma Flow
Takehiko SATO,Hideya Nishiyama,Makoto Kambe 한국물리학회 2003 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.42 No.III
Characteristics of breakdown voltage in a non-thermal plasma flow at atmospheric pressure were investigated %%@ experimentally. Breakdown voltages for different gap lengths of parallel plate electrodes were measured with %%@ respect to applied voltage rising rate, applied waveform, applied wave frequency, gas flow rate and kind of gas. %%@ The correlation between $pd$, which is the product of the pressure and the gap length, and breakdown voltage %%@ corresponded to Penning's experimental data of the applied voltage rising rates from 0.1 kV/s to 10 kV/s. However, %%@ the correlation was not in accordance with Penning's data when rising rates were greater than 100 kV/s. The %%@ breakdown voltages showed a minimum value when gas flow rates were 2 - 4 Sl/min for both argon and nitrogen gases. %%@ On the other hand, the correlation between breakdown voltage and $pd$ corresponded to the experimental data %%@ reported by Penning, Kind and Karner concerning the cases of sawtooth wave, sinusoidal wave and square wave with %%@ different wave frequencies of 100 Hz, 1 kHz and 10 kHz. Discharge current mode is classified into two modes and it %%@ was influenced by gas flow rate.
