A body manufacturing method of an oil-immersed amorphous alloy transformer

Abstract

The invention discloses a manufacturing method of a transformer body of an oil immersion type amorphous alloy transformer. The manufacturing method includes the following steps: (1) annealing treatment is carried out on iron cores; (2) the iron cores are pushed to the testing position for testing according to the furnace exiting sequence; (3) coils for forming the transformer body of the transformer draw close; (4) iron core jackets are drawn off after the iron cores are pushed into the testing position; (5) packing is carried out; (6) binding is carried out, wherein the binding belt tension ranges from 1500 N to 2500 N according to different weights of the transformer body; (7) after an amorphous sheet layer on the outmost face is closed, a shock pad is placed on the outer face of the amorphous sheet layer, a silicon steel sheet hasp on the outer layer is tightened, the hasp part is firmly glued through adhesive tape, and the adhesive tape is used for firm gluing if the hasp is damaged; (8) the coils are cleaned; (9) the lap joint position is coated with glass cement; (10) upper clamp insulation is arranged, and an upper clamp is installed in place. By means of the manufacturing method, stable-performance annealing parameters can be guaranteed, the fixing effect is improved through an elastic insulation binding belt, and the sound insulation effect and the sound absorption effect can be improved.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a method for manufacturing an oil-immersed amorphous alloy transformer body. Background technique [0002] In order to save costs, the oil-immersed amorphous alloy transformer must reduce the volume of the transformer body, and then reduce the amount of various raw materials. It is necessary to control the annealing of the transformer core and bind the transformer body to ensure the loss level of the transformer. Safe insulation distance and withstand voltage level, but because the amorphous core is very sensitive to stress, if the binding is too tight, the noise and loss of the transformer will increase. Loose noise will increase sharply, which is likely to damage the outsourcing insulation, and even cause multi-point grounding of the transformer, which will burn the transformer.
