Three Phase Oil Immersed 4000 KVA 4 MVA Power Transformer

Overview of Three Phase Oil Immersed 4000 KVA 4 MVA Power 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.

Features of Three Phase Oil Immersed 4000 KVA 4 MVA Power Transformer

• 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 Three Phase Oil Immersed 4000 KVA 4 MVA Power Transformer

Three Phase Oil Immersed 4000 KVA / 4 MVA Power Transformer: Your Questions Answered

What exactly is this transformer?
This is a big power transformer. It handles 4000 KVA or 4 MVA of electrical power. It uses three-phase electricity. The transformer sits inside a tank filled with special insulating oil. This oil cools the transformer. It also provides electrical insulation.

Where is this transformer used?
You find this transformer in places needing lots of power. It works well in factories, big buildings, power plants, and substations. It steps high voltage electricity down to safer, usable levels. Sometimes it steps voltage up for transmission over long distances.

How does the cooling work?
The insulating oil absorbs heat from the transformer core and windings. The hot oil naturally rises to the top of the tank. Cooler oil sinks to the bottom. This creates a natural flow. Larger transformers might have external radiators. Fans blow air over these radiators to help cool the oil faster.

What voltage levels does it handle?
The exact input and output voltages depend on your specific needs. These transformers are custom-built for the job. Common high voltage inputs might be 11kV, 33kV, or 66kV. Common low voltage outputs are often 400V, 6.6kV, or 11kV. You must tell the manufacturer your required voltages.

Is it safe?
Yes, safety is built in. The oil insulation is a key safety feature. The tank is strong and sealed. Pressure relief devices protect against internal faults. Temperature gauges monitor the oil. Specific safety devices detect internal problems like gas build-up. They stop major damage. Regular maintenance checks are essential for long-term safety.
