The high-voltage electrode plate of the plate-type ozone generator is usually a single-sided electrode plate, namely the high-voltage electrode plate only has one working surface, and the other surface is used as an electrode wire leading-out surface.
The single-sided high-voltage electrode plate structure solves the technical problems of insulation and creepage prevention, but cannot be said to be a perfect structure. When the high-voltage electrode plate is actually applied to the ozone generator, due to the consideration of technical links such as ozone yield, cooling efficiency and the like, the high-voltage electrode plate is inevitably required to be stacked in one ozone generator. At this time, in the single-sided high-voltage electrode plate structure, because only one surface of the single-sided high-voltage electrode plate structure is the working surface, the other surface of the single-sided high-voltage electrode plate structure needs to be led out of the electrode wire, and a certain structural thickness is needed for leading out of the lead wire and maintaining the elastic pressure between the adjacent electrode plates, the overall structure of the ozone generator using the single-sided electrode is determined to be complex and large in size, and therefore the single-sided high-voltage electrode plate is high in use cost and small in stacking density.
