Briefly describe what the power transformer does!

Intelligent manufacturing companies generally choose electric power engineering as electric energy, and the electric power engineering from the power station must be able to reach the electricity consumption area through long-distance transmission. When the transmitted output power moves at a constant speed, the higher the transmission working voltage, the smaller the amount of current required. Because the current is proportional to the amount of current. So what is the role of the power transformer?
 
 
The line loss is proportional to the square meter of the current flow. Therefore, with a higher transmission grid operating voltage, lower line pressure drop and line loss can be obtained. It is difficult to produce generator sets with a high operating voltage at this stage. Specially made machinery and equipment are used to increase the working voltage at the generator set and then the conveyor will come out. Such specialized machinery and equipment are called transformers.
 
At the same time, a step-down transformer must be used at the receiving end to reduce the high voltage to the operating voltage of the power distribution equipment system software. Therefore, a series of distribution transformers must be used to reduce the high voltage to a suitable value for supply. In order to give everyone a deeper understanding of the role of transformers, the following editor of Walker Energy will explain in detail:
 
1. The role of household transformers?
 
1. The most critical role of household transformers is to protect output power transmission, communicate with high-voltage transmission of AC, and in the power transformer, the transformer transforms the working voltage of the primary and intermediate levels to the secondary to carry out output power transmission.
 
2. Convert the working voltage from the high voltage and low voltage in the power line to the final voltage application. On the power transformer, the input working voltage is converted into various levels of working voltage required by the customer according to the transformer, which shows a variety of application environments for food, clothing, housing, transportation, and industrial production.
 
 
3. The data signal transmission of another transformer, the magnetic protection in the power transformer means that the data signal is transmitted by the transformer, which is stable and reliable.
 
4. The protective drive of the transformer, according to the protection, will show the drive to different rated voltages. Wait, wait, there are so many applications of transformers. These are just a few of my analysis from the perspective of power transformers. I look forward to analyzing them from other perspectives.

Power frequency transformers are also called low frequency transformers to show that they are different from high frequency transformers used in switching power supplies. Power frequency transformers have been used in large quantities in traditional power supplies in the past, and the stability of these power supplies uses linear adjustment, so those traditional The power supply is also called a linear power supply. The power frequency generally refers to the frequency of the mains electricity, which is 50Hz in our country and 60Hz in other countries. The transformer that can change the voltage of the alternating current at this frequency is called a power frequency transformer.

Now, switching power supplies generally use half-bridge power conversion circuits, which contain high-frequency transformers and transistors. When the circuit is working, the transistors are turned on in turn to generate high-frequency pulses with a frequency of 100KH, which are worthy of high-frequency pulses. Then they are stepped down by a high-frequency transformer, and finally the alternating current with a lower voltage is output. The specific voltage value is determined by each winding coil in the high-frequency transformer. The turns ratio is determined. Generally, three transformers are used, which are called the main transformer, the drive transformer and the auxiliary transformer. Each transformer has its own measurement specifications and functions, so one is indispensable.
