Low-energy-consumption stereo transformer iron core and manufacturing technology thereof

Abstract

The invention discloses a low-energy-consumption stereo transformer iron core and a manufacturing technology thereof. The low-energy-consumption stereo transformer iron core comprises an upper supportcomponent, a lower support component and three iron core bodies, wherein the three iron core bodies are distributed as a stereo equilateral triangle; each iron core body is formed by uniformly distributing multiple silicon steel sheets; each silicon steel sheet is elliptical; and an ellipse is arranged at the middle of each silicon steel sheet. In the invention, the three iron core bodies are fixed through an upper bracket and a lower bracket, to form the stereo equilateral triangle; meanwhile, an elliptical cavity is formed in the middle of each iron core body, and an air channel can be formed to improve the heat dissipation effect; and a nearly circular support body is formed on the side edge of the iron core body through the slopes on the inner side and outer side, the material consumption for winding a coil can be reduced, the cost is lowered, and the volume of the transformer is decreased. In the invention, the technology design is reasonable, the production efficiency is high, the product has perfect usability, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of power transformers, in particular to a low-energy-consumption three-dimensional transformer core and a manufacturing process thereof. Background technique [0002] In recent years, countries around the world are facing an increasingly serious energy crisis, requiring power equipment, including transformers, to further reduce losses and improve energy utilization. Transformer energy saving is an important indicator for evaluating the quality of transformers. Its energy-saving indicators include power supply energy loss and raw material loss indicators. [0003] As we all know, the iron core body is an indispensable core component of the magnetic circuit of a power transformer. The transformer is mainly composed of an iron core body and a coil. Waste, the loss of energy will also increase the temperature of the iron core. If the iron core works at high temperature for a long time, the insulating layer on i...

[0003] As we all know, the iron core body is an indispensable core component of the magnetic circuit of a power transformer. The transformer is mainly composed of an iron core body and a coil. Waste, the loss of energy will also increase the temperature of the iron core. If the iron core works at high temperature for a long time, the insulating layer on its surface will age, which will further increase the loss; not only that, in the process of transformer manufacturing, often Because of the structure of the iron core, the coil winding will be wasted, which will not only increase the loss of raw materials, but also increase the volume of the transformer
