Insulator structure for high-voltage transformer and manufacturing method thereof

The invention provides an insulator structure for a high-voltage transformer applied to the technical field of high-voltage transformers, and further relates to a manufacturing method of the insulatorstructure for the high-voltage transformer. An upper porcelain bushing (2) and a lower porcelain bushing (3) of the insulator structure for the high-voltage transformer are sleeved on a bolt (1); theupper end of the upper porcelain bushing (2) is attached to a sealing ring I (4) sleeved on the bolt (1); the sealing ring I (4) is propped against a limiting table (10); the upper end of the lower porcelain bushing (3) extends into the upper porcelain bushing (2); a nut (6) is screwed at the lower part of the lower porcelain bushing (3); an oil duct (9) is arranged at the lower end of the bolt (1) and is communicated with a gap (11). According to the insulator structure for the high-voltage transformer and the manufacturing method of the insulator structure, it is ensured that the insulatoris good in high-voltage ins
