The invention relates to a high-repeatability standard bubble discharge model device which comprises a high voltage electrode, a grounding electrode and bubbles between the high voltage electrode and the grounding electrode, the high voltage electrode and the grounding electrode are cylinder-shaped, the cylinder bottom of the high voltage electrode and the cylinder bottom of the grounding electrode are relatively arranged at two ends of an insulation column in a spaced mode so as to form an integrated structure, wherein the insulation column is made in a pouring mode. Threads are formed in the high voltage electrode, a high voltage electrode threaded column can be rotated vertically in the high voltage electrode, and the other end of the high voltage electrode threaded column is connected with a high voltage electrode plate. The grounding electrode is connected with a grounding electrode plate through spring pieces, the high voltage electrode plate is connected with the grounding electrode plate through the insulation column, and organic glass is arranged between the high voltage electrode plate and the grounding electrode plate so as to be sealed, and a sealing ring is arranged at each end of the organic glass. The bubbles in the whole material of the insulation column are formed by adopting a laser inner engrave method, the bubbles are standard and suspend completely, the defects of materials formed by machining operation are avoided, and discharge along the dielectric surface of a processing groove is avoided. The high-repeatability standard bubble discharge model device has the advantages of being stable and single in electro-discharge, and good in repeatability.
