Abstract

The invention discloses a surface discharge electrode structure capable of lowering discharge voltage and belongs to the technical field of surface discharge. Specifically the invention relates to a direct current or alternating current surface discharge electrode structure so as to solve problems of overhigh firing voltage and maintaining voltage for electric discharge in technologies of the prior art. The surface discharge electrode structure comprises a substrate and two discharge electrodes symmetrically arranged on the substrate, wherein protruding tips are respectively arranged on side walls, facing toward each other, of the two discharge electrodes; the protruding tips are respectively arranged on ends, facing toward each other, of the discharge electrodes; the protruding tips arranged on the two discharge electrodes are symmetrical. While a discharge current is basically kept unchanged, firing voltage and maintaining voltage for surface electric discharge can be remarkably lowered via the surface discharge electrode structure.
