34.5kv Transformer Fully Sealed Three-phase Oil-immersed Power Plant Distribution Transformer

Overview of 34.5kv Transformer Fully Sealed Three-phase Oil-immersed Power Plant Distribution 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 34.5kv Transformer Fully Sealed Three-phase Oil-immersed Power Plant Distribution 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 34.5kv Transformer Fully Sealed Three-phase Oil-immersed Power Plant Distribution Transformer

This transformer handles 34.5 kilovolts. It’s built for power plants and big distribution jobs. The design uses three phases. This is standard for heavy-duty power flow. The transformer is fully oil-immersed. The oil cools the core and windings. It also provides insulation. The entire unit is sealed tight. This prevents the oil from leaking out. It also stops air and moisture getting in. This sealing makes the transformer very reliable. It needs less maintenance too.

The core uses top-grade silicon steel. This steel cuts down energy losses. It works efficiently. The windings are made from copper or aluminum. Copper offers better conductivity. Aluminum is lighter. Both choices are solid. The windings are carefully arranged. This ensures stable voltage output. The tank holding everything is sturdy steel. It protects the internal parts. The tank is welded shut permanently. This creates the complete seal. No gaskets can fail over time.

Cooling happens naturally. The oil circulates inside the sealed tank. Heat transfers to the tank walls. Air flows over the outside surface. This is called ONAN cooling. It’s simple and dependable. The transformer runs cool. This extends its working life. Efficiency is high. Energy losses stay low. This saves money on power bills. The design meets strict standards. It handles normal overloads safely. It also withstands short circuits.

Safety is important. The sealed tank eliminates fire risks from leaks. There’s no need for an oil conservator. The design is simpler. Pressure relief devices are included. They activate if internal pressure gets too high. This protects the tank. The transformer connects to bushings. These bushings are also sealed. They are rated for 34.5kV. Options include porcelain or polymer. Grounding points are clearly marked. Installation is straightforward. The transformer is built tough. It lasts for many years in demanding conditions. It complies with IEC and relevant national standards.

Applications of 34.5kv Transformer Fully Sealed Three-phase Oil-immersed Power Plant Distribution Transformer

This transformer handles 34.5 kilovolts. It is sealed completely. No air or moisture gets inside. This stops the insulating oil from breaking down. The oil keeps things cool and insulates the windings. Three-phase power moves efficiently through it. This design is built tough for power plants and big distribution networks.

It manages high voltage electricity safely. The sealed tank prevents leaks. This is vital near sensitive equipment or people. Maintenance needs drop significantly. You don’t need frequent oil checks or replacements. The system stays reliable for a long time.

Power plants use it near generators. It steps up voltage for sending power long distances. Substations also rely on it. It steps down voltage for local grids. Factories need this transformer for heavy machinery. Mines use it in harsh environments. Water treatment plants depend on its steady performance. Any large facility needing bulk power distribution finds it essential.

Its robust construction handles electrical surges. Overloads cause less stress. The oil insulation provides excellent protection. Internal parts stay clean and dry. This extends the transformer’s working life. Operational costs are lower over time. Power loss during transmission is minimized. Energy efficiency is a key benefit. Installation is straightforward due to its durable, self-contained design. Reliability is assured in demanding settings.

5 FAQs of 34.5kv Transformer Fully Sealed Three-phase Oil-immersed Power Plant Distribution Transformer

Here are 5 FAQs for the 34.5kV Fully Sealed Three-Phase Oil-Immersed Power Plant Distribution Transformer:

What is this transformer?
This transformer is built for power plants. It steps down high voltage electricity, specifically 34.5kV. It uses oil for cooling and insulation. The entire unit is sealed tight. This design prevents air and moisture from getting inside the oil tank.

Why is it fully sealed?
The full seal is crucial. It stops the transformer oil from contacting outside air. Air exposure causes the oil to degrade faster. Moisture entering the oil seriously hurts its insulating power. Sealing the unit keeps the oil clean and dry inside. This extends the oil’s life and boosts the transformer’s reliability. It also cuts down on maintenance needs.

Why use oil inside?
Oil is essential here. It does two main jobs. First, it absorbs heat generated when the transformer operates, keeping it cool. Second, oil acts as a powerful electrical insulator. This insulation prevents dangerous short circuits between the high-voltage internal parts and the grounded tank. Oil handles these tasks effectively for large, powerful transformers like this one.

What does “Three-Phase” mean?
“Three-Phase” describes the electrical system it works with. Power plants generate electricity using three separate waves of power. These waves are offset from each other. This transformer handles all three phases together in one unit. Three-phase power is the standard for efficient electricity generation, transmission, and distribution in industrial settings and power plants.

Where is this transformer used?
Its main job is inside power stations. It connects directly to the power plant’s own electrical system. It takes the moderately high voltage (like 34.5kV) produced or used within the plant. Then it steps this voltage down to a lower level. This lower voltage powers the plant’s internal equipment and machinery needed to run the facility.
