CN201036129Y - Core Assembly and Coil Compression Structure of Amorphous Alloy Dry-Type Transformer - Google Patents

Abstract

The utility model relates to an iron core assembly and coil compression structure of an amorphous alloy dry-type transformer, which comprises a coil (1), an iron core (5), a clip (8), an iron core support plate (9), and a pressing block (2 ) and pressure nails (3), characterized in that the core support plate (9) is fixed on the clamp (8), and the clamp (8) has a circular hole. Because the utility model fixes the iron core support plate on the clamp instead of the coil, the gravity of the iron core is transmitted to the clamp through the iron core support plate, so that the force of the iron core and the pressing nail on the clamp can cancel each other, thereby reducing the steel plate used for the clamp At the same time, the spacer between the core and the coil is canceled, which simplifies the assembly process and reduces the cost.

Description

Core Assembly and Coil Compression Structure of Amorphous Alloy Dry-Type Transformer

technical field

The utility model relates to a structural improvement of a transformer, in particular to an iron core assembly and coil compression structure of an amorphous alloy dry-type transformer. It belongs to the technical field of power transformers.

Background technique

At present, amorphous alloy dry-type transformers generally adopt a structure in which the iron core 5 is suspended on the coil 1 through the spacer 7 and the iron core support plate 6, and the coil 1 is pressed by the pressing nail 3 installed on the clamp 4, as shown in Figure 1, Figure 2 shows. Fig. 1 is a schematic diagram of the core assembly and coil compression structure in the prior art, and Fig. 2 is a sectional view along the line A-A of Fig. 1 . Because the reaction force on the clamp 4 is all borne by the clamp 4 when the pressure nail 3 compresses the coil 1, the clamp 4 needs to be made of a steel plate with sufficient thickness to meet the mechanical strength requirement. At the same time, this assembly method adopts the spacer 7, and the use of the spacer 7 increases the difficulty of assembling the transformer and also increases the cost of the transformer.

Utility model content

The purpose of this utility model is to provide a new type of iron core assembly and coil compression structure for the deficiencies of the existing technology, so that the force of the iron core and the pressing nails on the clamp can cancel each other, thereby reducing the thickness of the steel plate used in the clamp ; At the same time, the spacer between the iron core and the coil is canceled, which simplifies the assembly process and reduces the cost.

In order to achieve the above-mentioned purpose, the utility model is achieved by taking the following technical solutions:

Core assembly and coil compression structure of amorphous alloy dry-type transformer, including coil 1, core 5, clip 8, core support plate 9, pressure block 2 and pressure nail 3, characterized in that the core support plate 9 is fixed On the clip 8 , a round hole for fixing the iron core support plate 9 is opened on the clip 8 . The gravity of the iron core is transmitted to the clamp through the core support plate, which offsets the force of the pressing nail on the clamp.

The beneficial effects of the utility model are: because the utility model fixes the iron core support plate on the clamp instead of the coil, the force of the iron core and the pressing nail on the clamp can cancel each other, thereby reducing the thickness of the steel plate used in the clamp. At the same time, the spacer between the iron core and the coil is eliminated, which simplifies the assembly process and reduces the cost.
