Three Phase Oil Immersed Power Transformers 6.6KV To 400V

Overview of Three Phase Oil Immersed Power Transformers 6.6KV To 400V

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 Power Transformers 6.6KV To 400V

• 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 Oil Immersed Power Transformers 6.6KV To 400V

These three-phase oil immersed power transformers accurately tip down greater 6.6 kV voltages to usable 400V degrees. They handle significant power demands securely. The core makes use of high-grade silicon steel laminations. This decreases power losses during procedure. The copper or light weight aluminum windings sit inside a durable steel storage tank. This container gets loaded with top notch shielding mineral oil. The oil does a number of crucial work. It cools the transformer efficiently. It additionally gives remarkable electrical insulation. This insulation prevents unsafe brief circuits.

The transformer includes a welded tank building. This avoids oil leaks. It also keeps moisture out. Radiators connect to the tank sides. These radiators increase the area. Natural oil circulation cools the windings. Warm oil increases. It flows with the radiators. Air cools down the oil. Cooler, denser oil sinks back down. This cycle takes place continuously. It preserves secure operating temperatures. Followers are optional. They improve cooling ability for greater loads.

Key voltage scores start at 6.6 kV. Secondary voltages provide 400V. The transformer links to three-phase systems. Common regularity is 50Hz or 60Hz. Insusceptibility worths are very carefully managed. This safeguards equipment throughout faults. The transformer achieves high efficiency. It decreases thrown away energy. This conserves operating expense. Sound degrees remain reduced. This is very important for close-by areas.

Security is a significant emphasis. The container includes a conservator tank. This enables oil to expand safely. A breather maintains air dry. It stops moisture going into the oil. Unexpected pressure constructs inside trigger an alleviation device. This stops container rupture. An oil degree gauge shows the oil amount plainly. Temperature signs keep track of winding warm. Basing terminals link the container safely to earth.

These transformers are crucial devices. They power factories accurately. They run big buildings. They supply mines and processing plants. They are developed tough for continual obligation. Low upkeep is a key benefit. They supply trustworthy voltage conversion for decades.

Applications of Three Phase Oil Immersed Power Transformers 6.6KV To 400V

Three phase oil immersed power transformers step down power. They change 6.6 kilovolts to 400 volts. This voltage is standard for many sectors. Manufacturing facilities require these transformers. Big machines and motors operate on 400 volts. The transformer materials stable power. Production lines rely on this. Motors start efficiently. Tools runs effectively.

Business structures make use of these transformers. Mall need them. Office blocks require them. Healthcare facilities require them too. They power illumination systems. They power air conditioning systems. They power lifts. They power all the crucial systems. Reputable power is essential below.

Renewable resource sites utilize these transformers. Solar farms generate power. Wind farms generate power. This power is commonly high voltage. Transformers step it down. Then it feeds into the regional grid. Or it powers equipment on-site. The transformer takes care of variable input.

Oil immersion is key. The oil cools the transformer. It insulates the inner parts. This permits heavy tons. This permits constant procedure. Warm dissipates properly. The transformer lasts much longer. Oil likewise aids reduce sparks. This boosts safety. Maintenance is easier too.

These transformers are built difficult. They rest outdoors usually. They handle climate. They manage dust. They handle temperature swings. The oil storage tank is sealed. It secures the core. It shields the windings. Integrity is the primary goal. Downtime expenses money. These systems maintain power streaming. They help several years.

5 FAQs of Three Phase Oil Immersed Power Transformers 6.6KV To 400V

What does this transformer do?
It steps down high voltage electricity. Specifically, it changes 6.6kV power from distribution lines to 400V power factories and big buildings need. This lower voltage runs heavy machinery safely.

Is it safe?
Yes. The transformer core and windings sit inside strong steel tank filled with special oil. This oil cools the parts. It also insulates them. This design prevents dangerous sparks or fires. The tank is sealed very well to keep oil in and dirt out.

How long will it last?
A long time with basic care. The oil is key. Check its level and quality regularly. Clean oil keeps the transformer cool and working right. Inspect connections and look for leaks. Do this yearly. Good maintenance adds years to its life.

How big is it?
Size depends on power needed. Small units fit on concrete pads. Bigger units need more space. They are heavy. Plan the location before delivery. Ensure the ground is strong and flat. Leave space around it for air flow and worker access. Check your site dimensions first.

How do I install it?
Get experts. This is heavy electrical gear. Trained technicians must handle delivery and placement. They connect the high voltage cables. They connect the low voltage cables. They fill the oil correctly. They test everything before turning it on. Never try this yourself.
