A Preliminary Research On The Electric Characteristic In Discharge Plasma And Catalyst Act On Together

At first, This paper designed a kind of high-voltage pulse power supply, The voltage, frequency could be regulated in 0-30KV, 0-10KHz ,At the same time , a new type of dielectric plate +γ—Al₂O₃ reactor on the basis of the theory has been improved. We study discharge characteristic of dielectric plate +γ—Al₂O₃ reactor ,including the influence of pulse voltage frequency , dielectric constants of dielectric plat , pulse voltage waveform , interval of discharge electrode on dielectric plate +γ—Al₂O₃ reactor discharge energy. The photo of discharge has been taken and the results were analyzed based on the data. The result shows: The maximum discharge energy(Pmax) of dielectric plate +γ—Al₂O₃ reactor largely relates with dielectric constant of dielectric plate, the disciplinarian is as follows: (1) Pmax(ε=8)> Pmax(ε=590) > Pmax(ε=3700) > Pmax(ε=14000). (2) Under different dielectric constants of dielectric plate, the discharge energy relates with voltage frequency. The less dielectric constants of dielectric plate, the larger the discharge energy. Under the single pole pulse (in the pulse duration range of paper study).The results following: (1) With the increasing of pulse duration from several hundreds to several ten hundreds nanosecond ,the discharge energy increase. (2) The discharge energy with dielectric plate is obviously larger than that without dielectric plate. In the pulse duration range of the paper, The maximum discharge energy occur when dielectric constant of plate is 590. (3) The shorter the pulse duration, The larger influence electrode interval on the discharge energy. The shorter electrode interval is more advantageous for increasing discharge energy.
