Making method of C-type ironic core of voltage mutual inductor

Abstract

The preparing method of voltage transformer C type iron core is based on voltage transformer C type iron core; the silicon steel disc is cut into bar-type piece, the bar-type piece is placed in a groove; two ends of the bar-type piece are blocked by two clips, bar-type piece blocked is placed on U type mould, up and down, left and right are pressed to C type iron core at the same time, two ends of the C type iron core are spot welded, hot processed, dipped, two C type iron core ends are cut, rubbed. The invention not only can save time and save work, increase efficiency, increase compactness, increase quality of product, standard flow production can be realized, and output can be increased greatly. More importantly the leftover material of silicon steel disc can be used to decrease spending. The invention is scientific, possesses advantages and performance of the same product, it possesses extreme practicality; and fits for usage of various departments.

Description

technical field [0001] The invention relates to a manufacturing method of a transformer iron core, in particular to a manufacturing method of a C-shaped iron core of a voltage transformer. Background technique [0002] The transformer is a very important device for the power generation, power supply and power consumption departments. It is also in a very critical position in the power grid. The connection of the transformer with the indicating instrument and the relay protection is to ensure the safe and reliable operation of the power grid and the normal It is one of the most important equipment for working and living electricity, and the structure and production quality of the transformer, especially the production method of the transformer core directly affects the quality and safety of the power supply. Although the production of transformers is a relatively mature technology, in order to improve the quality and safety of power supply and electricity consumption, accordi...

AI Technical Summary

Problems solved by technology

Since the section of the C-shaped rectangular iron core is an approximate cylindrical shape composed of multiple long silicon steel sheets, different molds must be replaced for each long silicon steel sheet of different width during the rolling process. It needs to be readjusted, so the current common rolling method is time-consuming and labor-intensive, and it is difficult to ensure the compactness and uniformity of the shape of the C-shaped rectangular core. This brings considerable difficulty to standardized mass production, and also directly affects To the quality of the product, it is difficult to achieve mass production
