Overview of Three Phase 10MVA 10 MVA 10000 KVA Power Transforme With

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 10MVA 10 MVA 10000 KVA Power Transforme With

• 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.

Specifications of Three Phase 10MVA 10 MVA 10000 KVA Power Transforme With

This transformer handles three-phase electrical systems. Its power rating is 10 MVA (10,000 kVA). It efficiently steps voltage up or down in substations or industrial power networks. The core uses high-grade grain-oriented silicon steel. This minimizes energy losses during operation.

The transformer uses mineral oil for cooling and insulation. It employs the ONAN cooling method. This means oil circulates naturally, air cools the radiators naturally. Larger units might use fans (ONAF) for extra cooling capacity. The tank is welded steel, robust and leak-proof. External radiators provide the necessary cooling surface.

Standard primary and secondary voltage ratings are available. Common HV options include 11kV, 33kV, 66kV. Common LV options are 6.6kV, 11kV, 33kV. Custom voltages are possible. The impedance voltage typically falls between 5.5% and 10%. This value depends on the specific design requirements.

Connections follow standard three-phase configurations. Delta or Wye (Star) are typical for both windings. Bushings are porcelain or composite, rated for the system voltage. They provide safe external termination points. The transformer includes essential accessories. These are an oil level indicator, pressure relief device, thermometer, and drain valve. Silica gel breathers keep moisture out of the oil.

Efficiency is high, meeting or exceeding industry standards. Losses are minimized through careful design and material selection. The unit complies with relevant international standards. IEC 60076 is a key standard. Routine and type tests are performed. These tests confirm dielectric strength, temperature rise, and impedance.

The transformer is robustly built for long service life. It withstands normal short circuits. Physical dimensions vary based on voltage ratings and cooling design. Weight is significant due to the core, windings, and oil. Expect weights between 15 and 30 tonnes. Installation requires a solid foundation. Proper clearances are essential for safety and cooling.

Applications of Three Phase 10MVA 10 MVA 10000 KVA Power Transforme With

Three phase 10MVA transformers handle serious power jobs. They step voltage up or down efficiently. This makes them essential for many demanding situations.

Utility companies rely on them heavily. You find them in substations feeding cities or large towns. They take high transmission voltage, like 115kV or 230kV, and step it down to safer distribution levels, maybe 11kV or 33kV. They form the critical link between the long-distance grid and local power delivery. Multiple units often work together for reliability.

Big factories need these transformers too. Heavy machinery like large motors, massive furnaces, or processing lines uses huge amounts of electricity. A 10MVA unit provides the stable, high-capacity power these industrial sites demand directly from the incoming high voltage supply. It powers the entire operation reliably.

Renewable energy projects use them extensively. Big solar farms or wind turbine clusters generate power at medium voltage. A 10MVA transformer collects this power. It boosts the voltage significantly for efficient injection into the main transmission grid over long distances. They are key for getting green power to where it’s needed.

Large commercial complexes or critical facilities also depend on them. Think major hospitals, big data centers, large airports, or sprawling university campuses. These places have huge, constant power needs. A 10MVA transformer often serves as the main point receiving high voltage utility power. It then distributes it at usable voltages throughout the entire facility, ensuring essential operations keep running.
