Structure of amorphous alloy dry-type distribution transformer and manufacturing method thereof

Abstract

The invention discloses a structure of a non-crystal alloy dry type transformer and a method for manufacturing the same. The transformer comprises a three-phase non-crystalline alloy iron core, high and low voltage coils sleeved on iron core columns and upper clamping pieces arranged on the upper ends of the high and low voltage coils, and the transformer also comprises an insulation framework sleeved on the iron core columns and a plurality of aluminum-copper transition connectors fixed on the upper clamping pieces through insulated conducting wire clamps or insulators. The aluminum foil is used as a conducting material of the low voltage coils and wound on the insulated framework, and the head ends and the tail ends of the low voltage coils are fixedly connected with the aluminum-copper transition connectors respectively; and the high voltage coils are wound by copper conducting wires and sealed by epoxy resin, and are sleeved outside the low voltage coils. In the technical proposal, aluminum replaces copper, so that the transformer has the characteristic of low no-load loss of common non-crystalline alloy distribution transformer, and the transformer also has the advantages that the transformer has low material cost and light weight, and minimizes the influence of copper price raising on cost of the non-crystalline alloy distribution transformer, and lowers consumption of insufficient copper resources and the like.

Description

technical field [0001] The invention relates to a coil and body structure of a transformer, in particular to a 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 amorpho...
