The voltage transformer body binding structure is convenient to operate, reduces labor intensity and saves manpower; but also can ensure the buffering effect and the drying of the product and ensure the quality of the product.

Description

Structure is wrapped to voltage transformer ware body

Technical Field

The invention relates to a voltage transformer, in particular to a wrapping structure of a voltage transformer body.

Background

Voltage transformers are instruments for transforming voltages, similar to transformers. However, the purpose of transforming voltage by the transformer is to conveniently transmit electric energy, so that the capacity is very large, and usually kilovolt-ampere or mega volt-ampere is taken as a calculation unit; the purpose of voltage transformer transformation is mainly to supply power to a measuring instrument and a relay protection device, to measure the voltage, power and electric energy of a line, or to protect valuable equipment, a motor and a transformer in the line when the line fails.

At present, the iron core of the existing voltage transformer is wrapped by adopting a mode of half-folding two layers of crepe paper and half-folding one layer of polyester film, and the following defects exist in the specific production process:

1) the labor intensity of workers is high, and the working efficiency is low;

2) partial discharge of products is unqualified due to insufficient drying of crepe paper or moisture absorption in the die filling process;

3) and the iron core is often rejected due to unqualified errors caused by poor performance due to poor buffering effect caused by that the half-folding cannot be achieved by wrapping.

Disclosure of Invention

The invention aims to provide a voltage transformer body binding structure, which aims to solve the problems of low binding efficiency and high reject ratio in the prior art of voltage transformer body binding.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a structure is wrapped to voltage transformer ware body, its includes the voltage transformer mounting panel, be equipped with the shell body on the voltage transformer mounting panel, wherein, the interval is provided with two cushion rubber seats in the shell body, the recess has on the cushion rubber seat, set up the iron core in the shell body, around being equipped with voltage primary coil and voltage secondary coil formation voltage transformer ware body on the iron core, the both ends of voltage transformer ware body place in fix in the recess of two cushion rubber seats and through the mounting.

Particularly, the top of the outer shell is provided with a primary outlet plate, and the primary outlet plate is provided with a primary outlet terminal.

Particularly, the fixing piece is an electrical tape, and the voltage transformer body is fixed on the buffer rubber seat through the electrical tape.

Particularly, a secondary outlet box is arranged on the voltage transformer mounting plate and outside the outer shell.

Particularly, the section of the buffer rubber seat is of a U-shaped structure, and four corners of the outer part of the section of the buffer rubber seat are of arc curved surface structures.

Compared with the prior art, the voltage transformer body binding structure has the advantages that the voltage transformer body binding structure is convenient to operate, reduces labor intensity and saves manpower; but also can ensure the buffering effect and the drying of the product and ensure the quality of the product.
