Abstract: Some embodiments in the present disclosure provide a cooling apparatus for mold transformers, which may be installed at opposite sides of a lower portion of the mold transformer having a first space formed between a core and a low voltage coil and a second space formed between the low voltage coil and a high voltage coil, characterized in that the cooling apparatus comprises a duct extending from the cooling apparatus in a direction toward the mold transformer, a discharge port of the cooling apparatus is configured to direct toward lower ends of the low voltage coil and the high voltage coil, so that cooling air discharged from the duct is injected into the inside of the first and second spaces.

Abstract: A plasma decomposition apparatus and method for carbon dioxide decomposes carbon dioxide in a non-thermal plasma state into carbon and oxygen. The apparatus includes: a reactor for decomposing carbon dioxide with an inlet for inflow of carbon dioxide and a outlet for discharge of carbon and oxygen; a plurality of anodes placed in the reactor, having a rod shape elongated in a length direction; a plurality of cathodes placed among the plurality of anodes in the reactor, having a rod shape elongated in the length direction; and a power source applying a predetermined voltage between the plurality of anodes and the plurality of cathodes.

Abstract: A water purification system and method using an ionizer and an ozonation treatment for ionization, oxidation and/or decomposition of undegradeable contaminants is disclosed. A high electron-inducing voltage is first applied to the water in the ionizer so that undergradeable materials are ionized and/pr decomposed, then the water is mixed with ozone so the water is purified to be potable.
