Abstract

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 insulation effect and not prone to breakdown, the situation that leaked transformer oil pollutes equipment due to oil leakage of the transformer is avoided, and the complexitydegree during transformer cleaning is reduced.

technical field [0001] The invention belongs to the technical field of high-voltage transformers, and more specifically relates to an insulator structure for high-voltage transformers, and also relates to a method for manufacturing an insulator structure for high-voltage transformers. Background technique [0002] With the development of science and technology, solid-state pulse modulators have been widely used in electron accelerators, radar transmitters, and microwave sources for security inspection and flaw detection equipment. Among them, the high-voltage transformer is generally an oil-immersed transformer, and the high-voltage output of the oil-immersed transformer is derived from an insulator to meet the insulation requirements of the high-voltage output of the transformer.

AI Technical Summary

Problems solved by technology

During the insulator assembly process, due to the different assembly methods, selected materials and process methods of the insulators, the transformer is prone to problems such as loose insulators, oil leakage, and high-voltage insulation during use.

[0003] The conventional transformer is in a static state during use, and the insulator is not subjected to oil pressure. The above problems cannot be fed back. When the transformer is in motion, the insulator is under oil pressure. As the working time increases, the sealing ring is in the oil. There will be aging, the sealing effect of the insulator will become worse, the problem of oil leakage and loose insulator will gradually appear, and eventually lead to poor high-voltage insulation and breakdown, and due to the oil leakage of the transformer, the leaked transformer oil will pollute the equipment , it will be very troublesome to clean up
