Functional Principle of Three Phase 35KV 66KV 110KV 220KV 230KV 8mva 10mva 12.5mva 20mva 25mva 40mva 63mva 100mva 250mva 330mva Mv&hv Power Transformer

• 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.

Core building uses high-grade silicon steel. This reduces power losses. Windings are copper or light weight aluminum. They are carefully protected. The transformer sits inside a solid, sealed tank. The container holds special insulating oil. This oil cools the system and shields internal parts. Cooling approaches vary. Options include ONAN (oil-natural air-natural), ONAF (oil-natural air-forced), or OFAF (oil-forced air-forced). The right method relies on the transformer size and tons.

High voltage bushings safely link the transformer to power lines. They are made from porcelain or composite materials. These bushings deal with the high voltages reliably. Temperature level tracking is crucial. Gauges track oil and winding temperature levels. This stops getting too hot. Pressure alleviation devices secure the container. They turn on if inner pressure obtains too expensive.

Resistance voltage is a crucial spec. It affects power flow control and fault present levels. Devices are designed for certain frequency requirements. Usual frequencies are 50Hz or 60Hz. Installment can be outdoor or indoor. Outside devices need weatherproofing. Noise degrees are controlled. This is important near booming locations.

These transformers are crucial facilities. They run in electric substations. They link power generation plants to the transmission grid. They also link the transmission grid to regional distribution networks. Industries needing large power feeds use them as well. Integrity and efficiency are vital. They make certain secure power shipment over fars away.
