From powering our daily gadgets to enabling sophisticated artificial intelligence systems, transformers play an indispensable role in modern life. This comprehensive guide aims to explore the multifaceted world of transformers, delving into their information and applications across different domains. Whether you're a tech enthusiast, a student, or a professional seeking to enhance your knowledge, this A-Z guide will provide you with valuable insights into the transformative impact of transformers in our lives.

1. Overview of the concept of transformer

1.1 What is a transformer?

A transformer is an electrical device used to transmit electrical energy from one circuit to another without changing the frequency by changing the voltage between the input and output. Transformers are called static devices because they have no moving or rotating parts. The applications of transformers are quite diverse, suitable for many different fields.

Like other types of transformers, Sanaky’s transformers are used in power distribution and transmission systems. At the same time, the device also meets other needs such as providing power for welding machines, electric furnaces, testing machines, connecting rectifier circuits, etc.

1.2 Transformer operating principle

The device operates on AC power, based on two principles: the current running through the conductor creates a magnetic field and the phenomenon of electromagnetic induction. When the AC voltage is applied at the two ends of the primary coil, the phenomenon of magnetic flux variation inside the two coils will appear. This magnetic flux will pass through the primary and secondary coils, the induced electromotive force will appear in the secondary coil and change the initial voltage.

 

The operating principle can affect the ability to provide stable power when the transformer is applied in the grid system. In addition, the efficiency and stability of the transformer can also affect the ability to integrate renewable energy sources as well as the safety of industrial machinery and equipment.

1.3 Transformer classification

Like other transformers on the market, Sanaky’s transformers are made up of 3 parts: winding wire, steel core and casing. This is an important device for the power transmission and distribution system. Transformers are classified in many different ways, depending on their structure, purpose and usage. The classification is as follows:

  • Classification by structure: single-phase transformer and three-phase transformer.
  • Classification by function: step-down transformer and step-up transformer.
  • Classification by use: measuring transformer, test transformer, isolation transformer and autotransformer.
  • Classification by insulation method: oil-filled transformer and dry-type transformer.

1.4 Scope of application of transformers

Transformers are applied in many different fields to transform and supply suitable voltage for electrical systems and equipment. In power plants, transformers have the function of transforming voltage from low to high levels (power transformers), and from high to low levels (load transformers).

In the power distribution system, transformers help regulate and supply electricity to buildings, factories, production facilities, etc. In addition, in renewable energy projects, transformers play the role of connecting energy sources such as wind power and solar power to the main grid. Transformers are also widely used in the manufacturing industry to supply voltage to equipment, machinery or other fields such as agriculture, irrigation, etc.

The role of transformers in transmission 

2.1 Applications of single-phase transformers

Single-phase transformers are used to stabilize the inverter power grid in households. This device will help save power consumption, ensure safety and prolong the life of the electrical system.

One of the outstanding applications of single-phase transformers is that they can be used in backup power supply systems to supply power to equipment in case the main power supply is interrupted. In particular, thanks to the core being welded across the entire range, it can help reduce noise during transformer operation.

2.2 Applications of three-phase transformers

A three-phase transformer is an important device in a three-phase power system and has many important applications in various industries and electrical systems. The machine has the ability to transmit energy or convert alternating current from one voltage to another while ensuring that the input frequency remains the same.

Compared to single-phase transformers, three-phase transformers have a more complex structure and are an indispensable component of the electrical power supply system in factories and industrial works. Transformers are often installed in places with high power consumption requirements such as hospitals, shopping malls, apartments, transformer stations, etc.

In the oil and gas industry, the application of three-phase transformers plays a role in supplying energy to equipment during the production process at transformer stations and power systems. In addition, three-phase transformers are also widely used in industrial refrigeration and air conditioning systems to supply energy to compressors and refrigeration equipment.

Application of transformers in life

Transformers are widely used in real life, especially in the process of transmitting electricity. Specifically, the device is used to increase the voltage of electricity transmission on low-voltage, medium-voltage and high-voltage lines. At the same time, they are also used as a voltage reduction tool in schools, hospitals, and industrial factories. Sanaky’s transformers are also particularly favored by the above units.

Basically, transformers will serve the following purposes:

  • Increasing and lowering voltage for power distribution

To transmit electricity over long distances and avoid loss, power plants (thermal power, hydropower, wind power, etc.) must use a booster to convert them into high-voltage lines and transmit them. During the transmission process, each small station will need a booster to boost the voltage to a stable value to avoid voltage drops when reaching the place of use. Once there, a step-down transformer is used to bring them back to medium voltage.

Conclusion

Transformers, often unseen but indispensable, are the backbone of our electrified world. From the moment you flip a switch to power your devices, to the transmission of electricity across vast distances, transformers play a crucial role. Their ability to efficiently convert voltage levels has revolutionized industries and our daily lives.

As we've explored, understanding the intricacies of transformers is essential for anyone seeking to grasp the fundamentals of electrical engineering or simply appreciate the technology that surrounds us. While their applications are vast and varied, their core principles remain consistent.

By delving into the world of transformers, we've gained a deeper appreciation for the engineering marvels that power our modern society.
