10/11kV Industrial Oil Immersed Transformer for Electrical Substation

Overview of 10/11kV Industrial Oil Immersed Transformer for Electrical Substation

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 10/11kV Industrial Oil Immersed Transformer for Electrical Substation

• 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 10/11kV Industrial Oil Immersed Transformer for Electrical Substation

This transformer handles heavy commercial lots. It steps down voltage for substation use. The main voltage rating is 10kV or 11kV. The secondary voltage matches your certain devices needs. Typical options include 400V, 415V, or 6.6 kV. This flexibility is necessary.

The core uses high-grade electric steel. This minimizes power losses. The windings are copper. Copper provides excellent conductivity. This ensures reliable power transfer. The whole assembly rests inside a durable steel storage tank. The tank is full of top notch protecting oil. The oil cools down the transformer. The oil likewise supplies important electrical insulation.

Different air conditioning methods are available. ONAN (Oil Natural Air Natural) is conventional. Air flows normally over cooling radiators. ONAF (Oil Natural Air Forced) uses followers. Followers enhance cooling down ability. This suits higher need scenarios. The transformer withstands harsh problems. It runs dependably in high ambient temperatures.

Security features are integrated. A stress alleviation device secures versus inner mistakes. An oil level gauge reveals the oil volume. A temperature level sign checks operating warm. These features protect against damages. They ensure lengthy life span.

The transformer meets strict international standards. IEC 60076 is crucial. This guarantees performance and safety. Building concentrates on long life. It manages regular tons changes. It sustains electrical surges common in substations. Marginal upkeep is required. This reduces functional expenses.

Power performance is a concern. Low no-load losses conserve power. Low tons losses minimize waste throughout procedure. This transformer gives reputable power distribution. It develops the foundation of your substation. Its durable layout makes sure continual operation.

Applications of 10/11kV Industrial Oil Immersed Transformer for Electrical Substation

These 10/11kV oil-immersed transformers are important for power substations. They step down high voltage electrical power from the main grid. This reduced voltage is secure for circulation inside commercial sites. Manufacturing facilities, mines, big processing plants rely on them. They give stable power for heavy machinery. Motors, production lines, big illumination systems require this power.

Their layout uses mineral oil. This oil serves two tasks. It cools down the transformer components. It likewise protects online elements. This oil bath makes them very trustworthy. They take care of challenging problems well. Warmth build-up is much less of a problem. They can take care of brief overloads much better than completely dry kinds. This issues throughout top commercial need.

These transformers are constructed strong. They function outdoors in substations. Weather, dust, temperature level swings don’t stop them. Their durable storage tank shields the core and windings. Workers can keep them quickly. Oil levels and problem are basic to check. Safety functions like pressure safety valve are common. They protect against failings if troubles occur inside.

Substations position them near the tons facility. This decreases long low-voltage wire runs. Much less power obtains shed over distance. Voltage stays stable at the equipment. The transformer links straight to the substation switchgear. This produces a safe power center for the entire enterprise zone. Ports, large commercial facilities, utility booster terminals additionally use them. They are a typical, proven solution for trusted medium-voltage power conversion.

5 FAQs of 10/11kV Industrial Oil Immersed Transformer for Electrical Substation

What is a 10/11kV oil immersed transformer?
This transformer changes high voltage electricity to lower voltage. It uses special oil inside its tank. The oil cools the transformer. The oil also insulates the internal parts. It handles voltages like 10,000 volts or 11,000 volts. This is common for industrial power distribution.

Where is this transformer typically used?
You find this transformer inside electrical substations. Substations serve factories, large buildings, and industrial parks. They are the main point for stepping down high voltage from the grid. They supply the safer, usable voltage for machines and equipment inside the facility.

What are its main features?
This transformer uses mineral oil for cooling and insulation. It has a strong steel tank protecting the core and windings. It has bushings for connecting high voltage and low voltage cables. It includes safety devices. These are things like pressure relief valves and temperature gauges. It is built tough for reliable outdoor or indoor substation use.

Is it safe?
Safety is a major focus. The tank is very strong. It contains the oil under normal conditions. Special safety valves release pressure if internal faults happen. This prevents dangerous explosions. The oil itself helps stop electrical arcs inside. Regular testing ensures it meets strict safety standards for industrial sites.

How do I maintain it?
Regular checks are vital. You must monitor the oil level inside the tank. Look for leaks around the tank welds or gaskets. Check the color of the silica gel in the breather; change it when it turns pink. Take oil samples for lab testing. This checks the oil’s insulating quality and finds hidden problems. Keep the transformer and its cooling radiators clean. Follow the manufacturer’s specific maintenance schedule closely.
