30 MVA 45KV Oil Immersed Three-Phase Electrical Transformer Offering Efficient And Stable Performance

Overview of 30 MVA 45KV Oil Immersed Three-Phase Electrical Transformer Offering Efficient And Stable Performance

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 30 MVA 45KV Oil Immersed Three-Phase Electrical Transformer Offering Efficient And Stable Performance

• 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 30 MVA 45KV Oil Immersed Three-Phase Electrical Transformer Offering Efficient And Stable Performance

This 30 MVA, 45KV oil-immersed transformer delivers essential power for demanding industrial or utility networks. Built for three-phase systems, it efficiently steps voltage up or down. Its core design minimizes energy loss during operation. This translates directly into lower operating costs over the transformer’s long service life.

High-quality electrical steel forms the core. Precision-wound copper windings surround this core. These components are submerged in specialized insulating oil. The oil serves two critical jobs. It insulates the internal parts. It also carries away heat generated during use. Keeping the transformer cool is vital for stable performance.

The entire assembly sits inside a strong, welded steel tank. This tank protects the core and windings. It also safely contains the insulating oil. An external radiator connects to the tank. The radiator significantly increases the cooling surface area. This ensures heat dissipates effectively into the surrounding air. Good cooling prevents overheating. Overheating damages equipment.

Rigorous factory testing guarantees this transformer meets strict performance standards before shipment. Tests confirm the rated power capacity. They verify the insulation strength can handle 45KV stresses. Efficiency measurements prove low energy losses. These tests ensure reliability from day one.

Safety features are integrated. The design includes pressure relief devices. These protect the tank if internal pressure rises unexpectedly. An oil level gauge allows easy monitoring. Proper oil level is necessary for safe cooling and insulation. The transformer withstands typical electrical system surges and short circuits. Its robust construction handles these events. This prevents damage and avoids costly downtime.

Installation is straightforward following standard practices. The transformer requires a solid, level foundation. Regular maintenance is simple. Checking the oil level and condition is the primary task. Keeping the radiator fins clean ensures optimal cooling. This transformer provides dependable power transfer year after year. It offers a practical solution for high-capacity electrical needs.

Applications of 30 MVA 45KV Oil Immersed Three-Phase Electrical Transformer Offering Efficient And Stable Performance

This 30 MVA, 45KV oil-immersed three-phase transformer is built for demanding power distribution. It reliably steps voltage up or down within medium to high voltage networks. You see it in substations, industrial plants, and places needing serious power transfer.

Its core design uses laminated silicon steel. This minimizes energy loss as magnetic fields change. The copper windings handle the high current efficiently. Everything sits inside a strong steel tank filled with special insulating oil. This oil is crucial. It cools the transformer. It also insulates the live parts very effectively.

The 30 MVA rating means it can handle significant power loads. It connects smoothly to 45KV systems. This makes it a key link for utilities and large industries. The oil immersion is a proven method. It keeps the transformer running cool even under heavy use. This prevents overheating. Overheating damages equipment. The oil also helps protect the internal parts. It stops moisture and air from causing problems.

Efficiency is a major focus. Careful design and quality materials reduce wasted energy. Less waste means lower operating costs over years of service. Stable performance is equally vital. This transformer delivers consistent voltage levels. Consistent voltage protects sensitive equipment downstream. It prevents flickering lights or machinery faults. It keeps the power flowing smoothly.

The robust steel tank protects the core and windings. It shields them from weather, dust, and physical harm. This construction ensures long life with minimal maintenance. Operators appreciate its reliability. It provides steady power day and night. It handles normal load variations without issue. It offers a dependable solution for critical power infrastructure.

5 FAQs of 30 MVA 45KV Oil Immersed Three-Phase Electrical Transformer Offering Efficient And Stable Performance

What is this transformer?
This is a big power transformer. It handles 30 megavolt-amperes. It uses oil for cooling and insulation. Its voltage rating is 45 kilovolts. It moves power efficiently between three-phase electrical systems. It’s built for reliability in demanding situations.

Where is this transformer used?
You find it in places needing lots of stable power. Think large factories, major mining operations, or big water treatment plants. Substations use it too. It connects reliably to medium-voltage grids. It’s for heavy-duty industrial or utility applications.

Why use oil immersion?
Oil does two main jobs. First, it cools the transformer parts very effectively. This stops dangerous overheating. Second, the oil acts as a top-notch electrical insulator. This prevents short circuits inside. The combination means better performance and a longer life under heavy loads.
