OZONE GENERATING TUBE, AND OZONE GENERATING APPARATUS EQUIPPED WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To provide technique by which an abnormal discharge between a cylindrical grounding electrode and a metal connecting part of a cylindrical high-voltage electrode is hardly caused. SOLUTION: The subject ozone generating apparatus is equipped with an ozone generating tube having an electrode structure which comprises: the cylindrical grounding electrode open at both ends; and the long high-voltage electrode composed of a plurality of high-voltage electrodes connected via a conductive metal terminal disposed on the end face of the electrode, with each electrode concentrically disposed inside the grounding electrode forming a gap therebetween and having a dielectric layer formed on the face opposing to the grounding electrode. The apparatus is equipped with: an insulating component at the end of the high-voltage electrode, the insulating component which can keep the creeping distance between the conductive metal terminal and the grounding electrode to be long enough to prevent thermal breakdown of the dielectric material; and an insulating ring having ozone resistance between the above insulating component and the end face of the high-voltage electrode so that the ozone-resistant insulating ring is pushed to the surface of the high-voltage electrode surface by the insulating component to improve the dielectric durability between the end face of the high-voltage electrode and the grounding electrode.
