Functional Principle of High Voltage 1500KVA Three-Phase Oil Immersed Transformer 1000kva & 800kva 630kva Power Distribution 3 Phase 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.

5 FAQs of High Voltage 1500KVA Three-Phase Oil Immersed Transformer 1000kva & 800kva 630kva Power Distribution 3 Phase Transformers

Here are 5 common questions about our 1500KVA, 1000KVA, 800KVA, and 630KVA Three-Phase Oil-Immersed Distribution Transformers:

Where do these transformers typically work? These transformers handle high voltage power distribution. You find them in substations. They work for industrial plants. They power large buildings. They are common in utility grids. They step down voltage for local use.

How does the cooling system work? The transformer core sits inside a tank. The tank is filled with special insulating oil. The oil absorbs heat from the core. The heat naturally rises. The hot oil flows towards the radiator fins. Air passes over the fins. This cools the oil. The cooled oil sinks back down. This cycle keeps the transformer at a safe temperature.

How often does it need maintenance? Regular checks are essential. Inspect the oil level monthly. Look for leaks around the tank and radiators. Monitor the oil temperature. Check the silica gel breather. It should stay blue. Schedule professional oil testing yearly. This checks insulation quality. A full internal inspection might happen every 5-10 years. It depends on operation and test results.

What safety features are included? These transformers have key protections. They include pressure relief devices. These vent the tank if pressure gets too high. They prevent explosions. Temperature sensors trigger alarms if things get too hot. Oil level gauges warn if oil is low. Bushings insulate the high-voltage connections safely. The sturdy tank protects the core. The oil itself is a fire retardant.

What is the efficiency like? These oil-filled transformers are very efficient. Modern designs minimize energy loss. Expect efficiency ratings above 98%. This means most power passes through. Very little turns into waste heat. High efficiency saves money. It reduces operating costs significantly over the transformer’s long life. The exact number depends on the load and specific model.
