Conheça como funciona o passo a passo da produção de transformadores de energia

Summary

The video provides an in-depth look at the transformer production process, starting from the cutting of silicon steel sheets to the winding of aluminum coils. The production process involves both high-tech machinery and manual labor, with workers carefully insulating and winding the coils. Once the coils are prepared, they are assembled with a core and secured using wooden spacers and screws. Afterward, the transformers undergo a drying process and undergo testing for quality control. The video also highlights the importance of using insulating materials to protect the transformer from moisture, particularly in humid environments like Manaus.

Takeaways

• 😀 The production of transformers begins with cutting the core using silicon steel sheets, which are processed in a specialized machine.
• 😀 The core material arrives from Minas Gerais, and it is cut precisely for transformer manufacturing.
• 😀 The next step in the process involves winding coils of aluminum wire, which are coated with an insulating enamel to ensure safety and functionality.
• 😀 The wire coils are made in multiple layers, with insulating paper between each layer for added protection against electrical faults.
• 😀 A single transformer may require between 2 to 3 kilometers of wire for the winding process, which takes about an hour per coil.
• 😀 Each three-phase transformer requires three coils, and these are produced using specialized machines designed for transformer winding.
• 😀 Operators manually fix the insulation and secure the wire, ensuring each coil is properly wound and insulated with cardboard and other materials.
• 😀 After winding, the coil is placed onto the core, which was previously prepared and is now ready for assembly on a workbench with rollers.
• 😀 The assembly process includes securing the core with wooden wedges to keep the coils in place before final sealing with bolts to prevent movement.
• 😀 Once assembled, the transformer undergoes a drying process in a special oven to remove moisture absorbed by the paper insulation, crucial for performance in humid regions like Manaus.

Q & A

What is the first step in the transformer production process?

The first step in the transformer production process is cutting the core, which involves using a machine that cuts sheets of silicon steel to the required size.

What material is used for the core of the transformer?

The core of the transformer is made from sheets of silicon steel, which are cut into the appropriate size for the transformer.

How is the winding of the transformer done?

The winding process involves using machines to wind aluminum-coated wires into coils, with paper insulation placed between the layers of wire. The wire is coated with an enamel insulation.

How long does it take to make a single coil of wire for the transformer?

It takes approximately 50 minutes to one hour to make a single coil, depending on the size of the coil.

How much wire is used to make a coil?

The length of wire varies depending on the power requirements of the transformer, but typically it can range from 2 to 3 kilometers of wire per coil.

What is the role of insulation in the winding process?

Insulation paper and the enamel coating on the wire are critical for preventing electrical short circuits and ensuring the safe operation of the transformer. The paper used is a high-insulation grade material.

How many coils are needed for a three-phase transformer?

A three-phase transformer requires three coils, one for each phase of the transformer.

What happens after the winding process is complete?

Once the winding process is complete, the coils are placed onto the core, which has been prepared in a previous step, and then the transformer undergoes a process of assembly and compression to secure the components.

What steps are involved in the assembly of the transformer?

During assembly, the core is closed around the coils, and wooden spacers are used to secure the coils in place. Tightening bolts are also added to ensure the core remains compact and stable.

What happens if the transformer is exposed to high humidity during production?

If the transformer is exposed to high humidity, especially in regions like Manaus, the insulating paper and cardboard in the coils absorb moisture. To counter this, the coils are placed in an oven to dry them out before proceeding with further steps.

What is the next step after the transformer assembly is completed?

After the transformer is assembled, it moves on to the drying process in an oven to remove any remaining moisture before undergoing testing and quality control procedures.

How is the quality of the transformers ensured during production?

The quality of the transformers is ensured through various stages, including tests, drying of the coils, and checking for the proper connection of the three phases. The assembly process is closely monitored to ensure proper function and safety.

What is the typical daily production output for the transformers?

The typical production output is around 30 to 40 transformers per day, which corresponds to 90 to 120 coils being used in the production of those transformers.
