11 13 14 MVA 12500 KVA 13000kVA 3 Phase Electrical Oil Immersed Power Transformer

Overview of 11 13 14 MVA 12500 KVA 13000kVA 3 Phase Electrical Oil Immersed 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 11 13 14 MVA 12500 KVA 13000kVA 3 Phase Electrical Oil Immersed 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.

This transformer deals with large power demands. It comes in several sizes: 11 MVA, 13 MVA, 14 MVA. That’s 12500 kVA, 13000 kVA. It’s a 3-phase oil-immersed power transformer. Its major job is tipping voltage up or down effectively. The main voltage normally links to high voltage systems. Common HV degrees are 33 kV or 66 kV. The secondary voltage feeds circulation networks. Standard LV degrees are 11 kV or 6.6 kV. Actual voltages match your details grid requirements.

The core makes use of high-grade grain-oriented silicon steel. This minimizes power losses. Copper or aluminum conductors form the windings. These carry the electric existing. The whole active component sits inside a strong steel tank. The storage tank obtains loaded with insulating mineral oil. This oil cools down the transformer. It also provides essential electric insulation.

Cooling occurs normally or with fans. ONAN cooling down uses oil and air normally. ONAF air conditioning includes forced air followers. Followers kick in when the lots increases. This keeps temperatures risk-free. The transformer has pressure and temperature assesses. These screen interior problems. An abrupt pressure relay offers immediate security. It triggers if internal stress climbs too quickly. This prevents significant damages. The container is sealed tight. This quits wetness and air from entering. It protects the oil high quality. Good oil top quality is necessary for long life and security.

The transformer fulfills stringent international criteria. It follows IEC 60076. It also complies with appropriate national requirements. These policies cover style, testing, and security. The transformer deals with heavy tons reliably. It functions well in demanding commercial setups. It also functions well in utility substations. Its robust construction guarantees dependable procedure. Appropriate installation and upkeep are crucial. They take full advantage of the transformer’s service life.

Applications of 11 13 14 MVA 12500 KVA 13000kVA 3 Phase Electrical Oil Immersed Power Transformer

These transformers handle big power jobs. They step down high transmission voltages to usable levels. Substations rely on them heavily. They feed power into local distribution grids. These grids supply towns and cities. The 12500 kVA, 13000 kVA models fit common substation needs. They manage the power flow reliably. Industrial plants need them too. Big factories use massive machinery. Motors, furnaces, and compressors demand stable power. An 11 MVA, 13 MVA, or 14 MVA unit provides this power directly. It connects right to the factory’s main supply. This avoids voltage drops across long lines. Mining operations are another key user. Heavy extraction and processing equipment runs constantly. These transformers deliver the necessary robust power. They handle tough conditions underground or at open pits.

Renewable energy sites depend on them. Large solar farms or wind parks generate power far from users. These transformers step up the voltage for efficient long-distance travel. They connect the clean energy to the main grid. Their design allows for variable loads. Wind and solar power output changes constantly. The transformer adjusts smoothly. Utilities trust them for grid stability. They form the backbone of power transfer points. Their oil insulation provides effective cooling. This cooling is vital for continuous heavy-duty operation. Overloads happen sometimes. These transformers handle short-term overloads well. Their robust build ensures long service life. Maintenance is straightforward. This reduces downtime costs. They are a proven solution for medium-large power delivery. Their application is widespread globally. Power flows reliably because of them. Factories keep running. Homes stay lit.

5 FAQs of 11 13 14 MVA 12500 KVA 13000kVA 3 Phase Electrical Oil Immersed Power Transformer

Here are 5 FAQs about 11, 13, and 14 MVA (12500 KVA, 13000kVA) 3-Phase Oil Immersed Power Transformers:

What is the main job of this transformer? It steps high voltage electricity down to lower voltage levels. It moves large amounts of power efficiently. It connects different parts of the electrical grid.

How does it stay cool? It uses special insulating oil. The oil circulates around the core and windings. The oil absorbs heat. Tubes or radiators attached to the tank let the heat escape into the air. Bigger units might need fans or pumps for extra cooling power.

Where are these transformers usually used? They are common in substations. Utilities use them for power distribution networks. They supply power to large factories. They supply power to big commercial complexes. They connect renewable energy farms to the grid. They handle heavy loads reliably.

What safety features does it have? It has a conservator tank. This tank holds extra oil. It lets the oil expand and contract safely. A breather stops moisture from entering the oil. Pressure relief devices protect the tank. Vents release pressure if something goes wrong inside. These features prevent leaks and damage.

How often does it need maintenance? Regular checks are essential. Technicians test the insulating oil quality often. They look for signs of aging or contamination. They inspect the tank exterior for leaks or rust. They check all connections are tight. They verify cooling equipment works properly. Major internal inspections need a qualified crew. Follow the manufacturer’s schedule strictly.
