Functional Principle of 110kv/220kv 80-200mva Oil-Immersed Auto-Coupling Three-Phase Main Power Transformer On-Load Voltage MV&HV Transformers

• Voltage conversion: The most basic function of a high-voltage main power transformer is to perform voltage conversion. It reduces the high voltage in the power system to the voltage level required by the user. By changing the turn ratio of the primary side (high-voltage side) and secondary side (low-voltage side) coils, voltage rise and fall can be achieved.
• Impedance matching: Transformers can also play a role in impedance matching. For different loads, their impedance values also vary. Through the transformer’s voltage transformation effect, the impedance of the load can be matched with the impedance of the power supply system, thereby ensuring stable current transmission.
• Voltage regulation: By changing the number of turns of the primary side coil or the number of turns of the secondary side coil, the output voltage can be adjusted. In the power system, transformers are used to achieve segmented voltage control to meet the electricity needs of different users and equipment.
• Filtering function: Some particular types of high-voltage main power transformers also have a filtering function, which can filter out harmonics and reactive power components in the power supply and improve the quality of the power supply.
