Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] see Figure 1-Figure 3 , an energy-saving transformer, including a core and a coil 4; the core is mainly composed of an upper iron yoke 1, a lower iron yoke 2 and a core column 3, and there are three core columns 3, and are located between the upper iron yoke 1 and the lower iron yoke 2 The three pillars are arranged in a character shape; the distance between the three pillars is equal.

[0030] There are direct seams between the upper iron yoke 1, the lower iron yoke 2 and the core column 3, and are filled with high magnetic permeability materials.

[0031] The cross-sectional area of ​​the magnetic flux of the upper iron yoke 1 and the lower iron yoke 2 is smaller than the cross-sectional area of ​​the core post 3 .

[0032] The upper and lower iron yokes and the core column are directly seamed and bonded by a special process to achieve a ful...

Abstract

The invention provides an energy-saving type transformer and a manufacturing method thereof. The energy-saving type transformer comprises an iron core. The iron core is mainly composed of an upper iron yoke, a lower iron yoke and core columns. The energy-saving type transformer is characterized in that the three core columns are arranged and located between the upper iron yoke and the lower iron yoke; the three core columns are arranged in a shape like a Chinese character 'pin'; the intervals between the three core columns are equal. Seams are filled with high-permeability materials, a magnetic circuit is improved, and no-load losses and no-load currents of the iron core are reduced. The transformer formed by directly sewing the rolled core is treated through a seam special process, compared with a traditional linear laminated core transformer, materials can be saved, production efficiency can be improved, and the production cost can be reduced; due to the fact that the magnetic circuit can be improved through the iron core columns, noise is also relieved and obviously reduced while the no-load losses and the no-load currents are small. A transformer coil can be independently wound and then installed on the iron core, and production efficiency is improved. The economical energy-saving type transformer core is provided for the transformer industry.

Description

technical field [0001] The invention relates to a transformer, in particular to an energy-saving transformer, which belongs to the technical field of electric power and distribution transformers. Background technique [0002] At present, most of the power and distribution transformers used in my country's power industry are traditional stacked core transformers. Laminated core transformers generally use oblique joints, so punching angles are required during the processing of core silicon steel sheets, and the punched off scraps will become waste, resulting in a certain degree of waste of materials. Moreover, the corner processing of the silicon steel sheet will increase the time required for cutting the sheet and increase the workload of the core lamination, which greatly reduces the efficiency of transformer production and increases the energy consumption required for production. Under the general environment that the country advocates energy conservation, the transformer ...
