Oil Immersed Transformer 3 Phase 6kv 10kv 25 Kv 100kva,400kva 200kva 11kv Oil Immersed Power Transformer

Overview of Oil Immersed Transformer 3 Phase 6kv 10kv 25 Kv 100kva,400kva 200kva 11kv 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 Oil Immersed Transformer 3 Phase 6kv 10kv 25 Kv 100kva,400kva 200kva 11kv 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 oil-immersed power transformer handles three-phase electrical systems. It comes in different power levels: 100kVA, 200kVA, and 400kVA. It works with various voltages like 6kV, 10kV, 11kV, and 25kV. The core uses high-grade silicon steel. This material cuts down energy losses significantly. The steel laminations are stacked tightly. This design minimizes wasted power.

Copper or aluminum conductors form the windings. These windings carry the electrical current. The windings are carefully arranged around the core. The entire assembly sits inside a strong steel tank. This tank is filled with special insulating oil. The oil does two important jobs. It insulates the live parts. It also cools the transformer by absorbing heat. This oil has high dielectric strength. It resists electrical breakdown well.

Heat builds up during operation. The oil naturally circulates. Hot oil rises. Cooler oil sinks. This movement helps transfer heat away. Larger units often have cooling fins or tubes. These increase the surface area. More surface area means better heat dissipation to the air. Some models include radiators. Radiators boost cooling capacity further.

Protection features are built-in. The tank includes an oil conservator. This is an expansion tank. It allows the oil to expand and contract safely. A breather prevents moisture from entering the oil. Moisture harms the insulating properties. A Buchholz relay detects internal faults. It provides early warning. An oil level gauge shows the oil quantity. A pressure relief valve protects against dangerous pressure build-up.

The transformer connects to power lines. It uses high-voltage bushings. These bushings safely pass conductors through the tank wall. Many units offer on-load or off-circuit tap changers. These adjust the output voltage slightly. This compensates for varying input voltage. The transformer meets standard efficiency and safety rules. It provides reliable power distribution or conversion.

Applications of Oil Immersed Transformer 3 Phase 6kv 10kv 25 Kv 100kva,400kva 200kva 11kv Oil Immersed Power Transformer

Oil immersed transformers handle power distribution efficiently. These strong units manage electrical energy safely. They suit many industrial and utility settings. Factories depend on them for reliable power. Mines and quarries use them in tough conditions. They work well for large buildings needing steady electricity. Substations integrate them into power grids. They step voltage up or down as needed.

These transformers come in common three-phase designs. They handle different voltage levels effectively. Lower voltages like 6kV or 10kV are standard. Higher voltages like 11kV or 25kV are also common. Power ratings vary widely. Units might be 100kVA for smaller needs. Larger installations often use 200kVA or 400kVA models. The right size depends on the load.

The oil inside is key. It cools the transformer effectively. It also insulates the internal parts well. This design allows continuous operation. It handles high loads better than some dry types. The oil needs checking and replacing sometimes. Proper maintenance ensures long service life. The strong tank protects the core and windings. These transformers are built for durability. They withstand demanding environments reliably.

They are vital for power distribution networks. Utilities rely on them daily. Industries count on them for production uptime. Their design makes them a practical choice. They deliver power where it’s needed most.

5 FAQs of Oil Immersed Transformer 3 Phase 6kv 10kv 25 Kv 100kva,400kva 200kva 11kv Oil Immersed Power Transformer

Oil Immersed Transformer FAQs: 3 Phase, 6kV-25kV, 100kVA-400kVA

People often ask about oil-immersed transformers. These are common power transformers. They handle medium voltages. Typical ratings include 6kV, 10kV, 11kV, 25kV. Common power sizes are 100kVA, 200kVA, 400kVA.

What is this transformer? It’s a device for changing AC voltage levels. It uses electricity in three phases. The core and windings sit inside a tank filled with insulating oil. This oil is key. The transformer steps voltage up or down for power distribution.

Why use oil? The oil does several jobs. It insulates the live parts. It stops electrical arcs. The oil also cools the transformer. Heat builds up during operation. The oil absorbs this heat. It carries the heat away to the tank walls. The tank surface then releases heat to the air. This keeps the transformer working safely. It prevents overheating damage.

What voltages does it handle? These transformers work with medium distribution voltages. Common primary voltages are 6kV, 10kV, 11kV, 25kV. The secondary voltage is usually lower, like 400V. You must match the transformer’s voltage rating to your system voltage. Using the wrong voltage is dangerous. It can destroy the transformer.

How do I pick the right size (kVA)? The size (like 100kVA, 200kVA, 400kVA) means its power capacity. You need to know your total load. Add up the power needed by all equipment it will supply. Choose a transformer size bigger than your peak load. This gives a safety margin. It prevents overload. Overload causes overheating and failure. Always check the load calculations carefully.

How often is maintenance needed? Oil transformers need regular checks. Inspect the oil level often. Look for leaks. Test the oil quality yearly. Oil breaks down over time. Bad oil loses its insulating power. It doesn’t cool well. Dirt and water in the oil are bad. Check connections and bushings. Listen for unusual noises. Follow the maker’s schedule. Good maintenance prevents failures. It makes the transformer last longer.
