Embodiment Construction

[0022] see figure 1 , and combined with figure 2 , image 3 , a method for manufacturing an amorphous alloy dry-type distribution transformer according to one of the present invention, comprising the following steps:

[0023] The first step is to manufacture the three-phase iron core 7 by winding. The three-phase iron core 7 is a four-frame five-column or three-frame three-column structure with a rectangular cross-section, which can be composed of one row or two rows of amorphous alloy cores stacked side by side. ;

[0024] The second step is to manufacture the combined clamps and insulating framework 3 composed of the end clamps arranged at the left and right ends of the high-voltage coil 5 and the upper and lower clamps 6 arranged at the outer ends of the low-voltage coil 4 at the upper and lower ends by machining. and an aluminum-copper transition joint 1, wherein the insulating skeleton 3 is a rectangular cylinder whose inner diameter matches the section of the three-p...

Abstract

The invention relates to a structure and a manufacture method of amorphous alloy dry distribution transformer, wherein the structure comprises a three-phase iron core, a high and a low tension coils which are respectively winded into a whole structure and which case on the three-phase iron core, an insulating frame arranged in the low tension coil, upper and lower clippers arranged at the upper and the lower ends of the high and the low tension coils, and a plurality of aluminum-copper transition joints fixed on the upper clippers by insulating wire clamps or insulators. The high and the low tension coils all employ aluminum as conducting material, and the high tension coil cases around the high tension coil after being bound with aluminum wires and encapsulated by epoxy. The manufacture method of amorphous alloy dry distribution transformer replaces copper with aluminum, which not only has the feature of low open circuit loss of common amorphous alloy distribution transformers but also is characterized by low material cost and light weight, thereby reducing effects caused by price rise of copper to cost of distribution transformers, and reducing 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 dry-type power 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 dry-type distribution transformer (hereinafter referred to as amorphous dry 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 dry conversion, and also restricted the promotion and application of amorphous d...
