The Design Of High-voltage Pairs Of Narrow Pulse Power

The pulse corona induced non-thermal plasma chemical process(PPCP) is the novelty method of flue gas desalfurization which has been widely developed in home and abroad Pulse power supply is the bottleneck of development of the pulse corona technology. Unipolar pulse discharge will lead to charge accumulate to reactor. With the charge not releasing the tail voltage will be formed. It will strengthen electric field which is formed by later pulse power supply, then make gap sparking discharge and induce injection of energy difficultly. Bipolar pulse power can avoid spark discharge efficiently, in addition, positive pulse corona do better to the effect of removing SO2 and negative pulse corona is the key of removing Nox. So dual-pulse power mathod has the market competition.In the paper, through the math analysis on high pulse discharge loop equations, the relationship between pulse voltage, pulse current, pulse rise time, pulse width and discharge loop parameters has been derived, the math model of high pulse discharge loop been established. Based on this theory, dual-pulse power has been designed, the influences of discharge loop parameters on pulse waveform been analyzed, the parameters of loop inductance, loop resistance and pulse forming capacitance been given, the influences of loop inductance, loop resistance, and pulse forming capacitance on pulse waveform were analyzed, non-linear resistance of wire-to-cylinder reactor been expressed piecewise, the matching of power and reactor been studied. Through the analysis on experimentation waveform of infuse energy, the conception of active power has been given, the matching of power and reactor been studied deeply.The paper has realized data sampling with oscillograph and the Spectrence, made deep , comprehensive research and study on power efficiency, matching of power and reactor, introduced the rarity experience to development of large industry implement.
