Oil Immersed Power Transformer 3150 Kva 3000 Kva 6300 Kva Transformer

Overview of Oil Immersed Power Transformer 3150 Kva 3000 Kva 6300 Kva Transformer

An oil-immersed transformer is a type of electrical transformer where the core and windings are submerged in an insulating oil. This oil serves two primary functions: it acts as a highly effective insulator between conductive parts and as a coolant to dissipate heat generated during operation. These transformers are robust, reliable, and highly efficient, making them the standard choice for high-voltage power distribution and transmission networks, typically installed outdoors in substations.

• Effective Cooling: The insulating oil efficiently absorbs heat from the core and windings and transfers it to the radiator fins, allowing for natural or forced circulation and higher overload capacity.
• Superior Insulation: The oil provides much better dielectric strength than air, allowing for a more compact design for a given voltage rating and protecting against short circuits.
• Robust Construction: Designed for long-term, reliable operation (often 25-30 years) in harsh outdoor environments.
• Overload Capacity: Can handle temporary power overloads better than dry-type transformers due to the thermal mass and cooling properties of the oil.
• Protection System: Equipped with a conservator tank (to allow for oil expansion), breather (to absorb moisture from air), and protective relays (Buchholz relay) for internal fault detection.
• Cost-Effective: Generally more economical for high-power applications compared to dry-type transformers.

5 FAQs of Oil Immersed Power Transformer 3150 Kva 3000 Kva 6300 Kva Transformer

What cooling systems do these transformers use?
These transformers mainly use ONAN or ONAF cooling. ONAN means oil circulates naturally inside the tank. Air flows naturally over the tank’s surface. ONAF also uses natural oil flow. Fans blow air over the tank’s surface. This helps remove heat better. Both methods keep the transformer working safely. The right system depends on the load and location.

Where should we install these oil transformers?
Install them outdoors or in well-ventilated indoor spaces. Good airflow is essential. They need space around them for cooling and safety. Keep them away from fire hazards. Ensure the ground slopes for oil containment. This protects the environment if leaks happen. The foundation must be strong enough. It holds the transformer’s weight and oil. Follow local safety rules exactly.

What regular maintenance do they need?
Check the oil level often. Look for leaks around the tank and valves. Test the oil quality yearly. This checks its insulation strength and moisture. Monitor the silica gel in the breather. Change it when it turns pink. Clean bushings and radiators. Inspect cooling fans and pumps. They must work correctly. Keep records of all checks and tests. This helps spot problems early.

What causes these transformers to fail?
Overloading is a big cause. It creates too much heat. This damages insulation over time. Moisture entering the oil is another problem. It lowers the oil’s insulation power. This can cause internal faults. Bad connections create heat spots. Loose connections can spark. Lightning strikes or voltage surges stress the insulation. Old age weakens materials. Poor maintenance makes these issues worse.

How long does a 3150kVA, 3000kVA, or 6300kVA oil transformer last?
Expect 20 to 30 years of service. This depends heavily on use and care. Running it within its rated load helps. Keeping the oil clean and dry is vital. Preventing moisture entry extends life. Avoiding overloads prevents premature aging. Regular maintenance finds small issues. Fixing them quickly prevents bigger failures. Good installation practices matter too. The environment affects lifespan. Harsh conditions shorten it.
