Embodiment Construction

[0025] see figure 1 A method for manufacturing an amorphous alloy oil-immersed distribution transformer, one of the present invention, comprises the following steps:

[0026] The first step is to manufacture the amorphous alloy iron core 7 by winding. The iron core 7 can adopt a four-frame and five-pillar or three-frame and three-pillar structure with a rectangular cross-section, and is composed of one or two rows of amorphous alloy cores;

[0027] In the second step, a rectangular insulating frame 3 is set in the low-voltage coil 4, and the inner diameter of the insulating frame 3 should match the cross-sectional size of the iron core 7, and the low-voltage coil 4 is directly wound on the insulating frame 3, and the low-voltage coil 4 The number of layers is the number of turns, and the turns are separated by interlayer insulating paper (not shown in the figure);

[0028] The third step is to wrap the main insulation (not shown in the figure) on the outer surface of the low-...

Abstract

The invention relates to a manufacture method of amorphous alloy oil-immersed distribution transformer which comprises a low-tension line copper-aluminum transition terminal block, an iron core, a high and a low tension coils and a clipper, wherein both the high and the low tension coils have rectangular layered structures, and the conducting material of the high and the low tension coils is metal aluminum. The invention also comprises a rectangular insulating frame arranged in the low tension coil which directly coils surrounding the insulating frame. The manufacture method not only has the feature of low open circuit loss of common amorphous alloy oil-immersed distribution transformers but also is characterized by low material cost and light weight, which reduces effects caused by price rise of copper to cost of oil-immersed distribution transformers, and reduces consumption of copper which is short in supply.

Description

technical field [0001] The invention relates to a body structure of a transformer, in particular to a body structure of an amorphous alloy oil-immersed distribution transformer and a manufacturing method thereof. Background technique [0002] The body of the transformer is composed of two parts, the coil and the iron core, and copper is the main raw material for manufacturing the transformer coil. my country's copper resources are very scarce, and long-term dependence on imports can meet the demand. In recent years, the international copper price has soared, which has greatly increased the material cost of transformers. [0003] Amorphous alloy oil-immersed distribution transformer (hereinafter referred to as amorphous distribution transformer) is a widely used high-efficiency and energy-saving product with extremely low no-load loss. The rising copper price has affected the cost performance of amorphous distribution transformers, and also restricted the promotion and appl...
