Arc Plasma Reactor Power System with 5-Limb Transformer

Abstract The arc plasma reactors are especially suitable for treatment of big volumes of exhaust gases emitted to the atmosphere during various technological processes. They can operate at three-phase power system and can be connected in series or in parallel to the gas flow. Their proper operation require power supply systems that should ionize the inter-electrode zone and maintain the cyclic and non-equilibrium operation of the arc discharge after ignition while presenting stable and reliable operation. Transformers of special construction are the basic elements of all of arc discharge plasma reactors power systems. Paper presents results of investigation of 5-limb transformer as a power supply for the arc plasma reactor. The possibility to take advantage of the voltage induced in the yokes of this kind of transformer for ignition of the discharge is also discussed.
