Power Transformer Parts And Functions
The power transformer is one of the most important components in the electrical power system. It is responsible for converting the voltage of the electrical power from one level to another. A power transformer can be found in all kinds of power systems such as power plants, substations, and transmission lines. In this article, we will discuss the different parts of a power transformer and their functions.
1. Core: The core is the heart of the transformer. It is the most important part of the transformer as it plays a vital role in the magnetic circuit of the transformer. The core is made up of high-quality laminated sheet steel. It is used to reduce the losses due to current induced in the core.
2. Windings: The windings are the coils of wires that are placed around the core. The windings are separately insulated from each other, and they are responsible for creating the magnetic field that helps in the transfer of electrical power.
3. Insulation: The insulation is used to protect the windings from coming into contact with the core or other conductive parts of the transformer. It also helps in the efficient transfer of power.
4. Tap changer: A tap changer is a mechanism that allows the transformer to be adjusted to different voltage levels. By adjusting the tap changer, the transformer can be used for different applications with different voltage requirements.
5. Cooling system: Transformers generate a lot of heat when operating at full load. The cooling system is responsible for removing the heat and maintaining the transformer at a safe operating temperature. There are various types of cooling systems like oil cooling, water cooling, and air cooling.
6. Bushings: Bushings are the parts used to connect the transformer leads to the power lines. They are made up of insulating material that protects the transformer leads from contact with the conductive parts of the power lines.
7. Conservator: A conservator is a part of the transformer that helps in maintaining the oil level. It is connected to the transformer by a pipe that allows oil to flow in and out of the conservator as required.
In conclusion, the different parts of a power transformer and their functions play a crucial role in the efficient and safe operation of the transformer. Each component has its significance and should be taken care of properly to ensure the long life and reliable operation of the transformer.
