11 KV To 400 Volt 800 1000 KVA 11kV 0.4kV 400V 1500kva Oil Immersed Distribution Power Transformer

Overview of 11 KV To 400 Volt 800 1000 KVA 11kV 0.4kV 400V 1500kva Oil Immersed Distribution 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 KV To 400 Volt 800 1000 KVA 11kV 0.4kV 400V 1500kva Oil Immersed Distribution 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.

Specifications of 11 KV To 400 Volt 800 1000 KVA 11kV 0.4kV 400V 1500kva Oil Immersed Distribution Power Transformer

This oil-immersed distribution transformer efficiently steps down high voltage for local power distribution. It converts incoming 11,000 volts (11kV) to a usable 400 volts (400V) output. Available capacities include 800kVA, 1000kVA, and 1500kVA models. This range suits various industrial sites, commercial buildings, and large infrastructure projects needing substantial power.

The core and windings sit inside a robust steel tank filled with high-grade mineral oil. This oil provides essential insulation and cooling. ONAN cooling (Oil Natural Air Natural) is standard. Heat transfers naturally from the windings to the oil. The oil then cools via the tank surface and radiators. This design ensures reliable operation without forced cooling components. The tank features welded construction for excellent leak protection. It includes lifting lugs and base frame skids. These allow safe handling and straightforward installation.

Built tough for harsh sites, the transformer withstands demanding conditions. It offers strong protection against overloads and short-circuits. Internal components utilize high-quality electrical steel and copper/aluminum conductors. This minimizes energy losses. The transformer meets strict efficiency standards. Expect low no-load and load losses. This translates to cost savings over its long service life.

Standard accessories include an oil level gauge, a pressure relief device, and a thermometer. These monitor vital operating parameters. An oil drain valve and filling plug simplify maintenance. Terminals accommodate various connection types. Options include air or gas cushion protection. The unit complies with international safety and performance standards like IEC 60076. It undergoes rigorous factory testing. This guarantees voltage withstand, temperature rise, and loss measurements meet specifications.

Applications of 11 KV To 400 Volt 800 1000 KVA 11kV 0.4kV 400V 1500kva Oil Immersed Distribution Power Transformer

This oil immersed distribution power transformer changes high voltage electricity to usable low voltage levels. It takes 11,000 volts input and outputs 400 volts. Capacities range from 800 kVA up to 1500 kVA. This covers many industrial and commercial power needs.

The transformer core and windings sit inside a strong steel tank filled with insulating oil. This oil does two critical jobs. It cools the transformer parts during operation. It also provides vital electrical insulation. This oil cooling design allows sustained heavy electrical loads. It also gives the transformer a long service life.

These transformers are built tough. They handle demanding environments like factories, mines, and large construction sites. Their main job is stepping down voltage for local distribution networks. They feed power directly to large buildings, shopping malls, hospitals, and data centers. They also connect renewable energy sources like solar farms to the main grid.

The oil immersion makes these units very reliable. They need less maintenance than dry types. The oil efficiently absorbs heat from the core and coils. This prevents overheating even during peak demand. The robust construction withstands electrical surges and harsh weather. These transformers work continuously for years with proper care.

Industrial plants depend on this transformer type. It powers heavy machinery, large motors, and extensive lighting systems. Utilities use them in substations close to neighborhoods. They deliver the final voltage step before electricity reaches homes and businesses. The 800 kVA to 1500 kVA size is ideal for medium to large power users. It efficiently transfers power over short distances after the main substation.

5 FAQs of 11 KV To 400 Volt 800 1000 KVA 11kV 0.4kV 400V 1500kva Oil Immersed Distribution Power Transformer

Here are 5 FAQs for the 11kV/400V Oil Immersed Distribution Transformer (800-1500kVA):

What exactly does this transformer do?
This transformer takes high voltage electricity from the power grid. It steps down the voltage. It changes 11,000 Volts (11kV) to a safer, usable level. The output is 400 Volts (400V). It powers factories, large buildings, and industrial sites.

How does it change the voltage safely?
High voltage electricity enters the primary winding. The core links the primary and secondary windings magnetically. This induces a lower voltage in the secondary winding. The transformer is filled with special insulating oil. This oil cools the windings. The oil also provides crucial electrical insulation.

Why choose an oil-immersed type?
Oil immersion gives excellent cooling. The oil absorbs heat from the core and windings. This prevents overheating during heavy use. The oil also boosts the transformer’s insulating properties. This design is very reliable. It lasts longer. It handles overloads better than dry types sometimes. It’s a proven, robust solution for demanding power distribution.

Where is this transformer typically installed?
You find these units feeding large power needs. They are common in substations. They supply factories, manufacturing plants, and processing facilities. They power large commercial complexes, hospitals, and university campuses. Any place needing lots of power at 400V uses them. They connect the high-voltage grid to the local low-voltage network.

What maintenance does it need?
Regular checks are essential. Technicians must monitor the oil level inside the tank. They test the oil quality periodically. Good oil is vital for insulation and cooling. They inspect for leaks, dirt, or damage to the tank and bushings. Connections need checking for tightness. More thorough maintenance involves oil testing and internal inspections by qualified personnel. Proper care ensures safety and a long lifespan.
