n modern energy systems, the transformer is an essential key equipment that provides a stable supply of food for our lives and industrial production. What exactly is a transformer and how does it work?
The basic principles of stress
A transformer is a device that USES the principle of electromagnetic induction to modify the ac voltame.it consists mainly of an iron core and two or more carts around an iron core. When a coil (called the main coil) is connected to an ac power supply, the ac creates a magnetic field in the iron core. This magnetic field is controlled by a second coil (called a secondary coil). According to Faraday's law of inducelectromagnetic, an electric force is induced in the secondary coil, causing a turn change. In simple terms, it is like the process of converting electromagnetic current, which increases or decreases the voltage at a certain rate.
2. Common types of transformers
STR. Storage mwandler
It is the most common type in transmission and distribution systems. In power transmission, booster voltages are used to increase the low voltage generated by the high-voltage power plant, thus reducing losses on the transmission line. In power distribution, downstream voltages are used to reduce the high voltage to a low voltage suitable for the user.
verteiltransformeren
It is normally installed close to consumers and converts high voltage current into low voltage current suitable for domestic, commercial and industrial applications. These are important devices that connect the power supply to the user.
Dedicated transformer
Designed and built for special USES. For example, electric furnace transformers are used to provide sufficient voltage and current for industrial electric furnaces. Direct transformers are used to convert alternating current into direct current and have important applications in fields such as electroplating and electrolysis.
Iii. Importance of voltage in power supply systems
Remote power supply
The use of staggered voltages to increase the transmission voltage and reduce the transmission current reduces the loss of resistance in the transmission line, allowing efficient power transfer over long distances. In this way, power from power plants can be efficiently supplied to different areas.
Ensure continuous power distribution
Distribution transformers convert high voltage electricity into stable low voltage electricity, providing sufficient working voltage for various electrical equipment and ensuring safe and constant energy consumption in places such as homes, factories and schools.
Supporting the economic functioning of the energy system
The rational allocation and use of voltage can maximise the efficiency of the electricity system, reduce energy consumption and improve the financial benefits of energy companies.
In general, as one of the basic units of the energy system, as common as they may seem, they play an important role in our lives. As science and technology continue to develop, transformers are also developing towards greater energy-saving, eco-friendly and smart, which helps build a more reliable and efficient energy system.
