(6) and (3) turning over the main body structure (26) of the baffle system by 90 degrees in cooperation with the hanging strips II (34) for laying down, and assembling the internal angle ring and the main body structure together to finish the manufacturing of the converter transformer baffle system.
2. The vertical manufacturing method of a converter transformer diaphragm system according to claim 1, wherein: and (3) assembling the partition board and the corner ring together to form an external corner ring by using the flanges, aligning the inner diameters of the corner ring (17) and the partition board (18), placing according to the relative positions of the drawing, fixing the corner ring (17) and the partition board (18) together by using the flanges (19), and clamping each corner ring (17) with the partition board (18) by using two flanges.
