Assembly device and method for horizontal body of dry amorphous alloy transformer

Abstract

The invention discloses assembly device and method for a horizontal body of a dry amorphous alloy transformer. The assembly method includes: opening an upper yoke of a core which is horizontal, allowing three-phase high and low voltage coils to penetrate through the upper yoke respectively, and closing the upper yoke of the core. Compared with vertical installation of the core, the method causes few core fragments during core opening and closing, and prevents the core fragments from falling into a small gap between the core and a guard plate. The requirement for single-point grounding between the core and the guard plate is guaranteed exactly. Technical performance indexes of products are well uniform. Compared with the general assembly process, the assembly method enables general assembly staff to be halved and general assembly efficiency to be doubled, so that production efficiency is improved greatly and product performance is stable. Tests show that the assembly method is evidently effective, product quality and production efficiency are improved greatly, and product performance is stable.

Description

technical field [0001] The invention relates to the field of transformer manufacturing, in particular to a device and method for assembling a horizontal body of a dry-type amorphous alloy transformer. Background technique [0002] The method used for the assembly of the amorphous alloy transformer body is (vertical installation method): the iron core opens the upper yoke of the iron core in a vertical state, respectively penetrates the three-phase high and low voltage coils, and then closes the upper yoke of the iron core. When opening and closing the iron core, due to the inherent characteristics of the amorphous alloy iron core material, fragments are easily generated, with different shapes and sizes, and the fragments are easy to fall into the small gap between the iron core and the iron core guard. Between, it is not easy to remove, the direct consequence is: the single-point grounding requirement between the iron core and the guard plate cannot be guaranteed, making the...

AI Technical Summary

Problems solved by technology

When opening and closing the iron core, due to the inherent characteristics of the amorphous alloy iron core material, fragments are easily generated, with different shapes and sizes, and the fragments are easy to fall into the small gap between the iron core and the iron core guard. Between, it is not easy to remove, the direct consequence is: the single-point grounding requirement between the iron core and the guard plate cannot be guaranteed, making the single-point grounding between the iron core and the guard plate uncertain! If it causes multi-point grounding between the iron core and the guard plate, the noise and iron loss indicators of the entire transformer will increase

In addition, during the implementation of the iron core vertical assembly process, there are many operators, the assembly efficiency is low, the consistency of various technical performance indicators of the product is poor, and the performance is unstable
