50KVA Oil-immersed Three-phase Power Transformer

Overview of 50KVA Oil-immersed Three-phase 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 50KVA Oil-immersed Three-phase 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 50KVA Oil-immersed Three-phase Power Transformer

This 50KVA oil-immersed transformer handles three-phase power. It steps voltage up or down reliably. The core uses high-grade silicon steel. This steel minimizes energy loss. Copper forms the windings. Copper conducts electricity efficiently. These materials ensure strong performance.

The transformer sits inside a welded steel tank. This tank holds insulating oil. The oil cools the core and windings. The oil also provides electrical insulation. This design allows continuous operation. It handles heavy loads well. The oil extends the transformer’s life.

Standard voltage ratings are common. Input and output voltages match typical systems. Examples include 11kV/400V or 33kV/400V. Other configurations are possible. The design includes tap changers. These adjust output voltage slightly. This compensates for supply variations.

The transformer operates quietly. Noise levels stay low. Efficiency is high. Less energy becomes wasted heat. This saves money over time. The unit meets strict standards. These cover safety and performance. It carries IEC or relevant certifications.

Radiators attach to the tank. These increase the cooling surface area. The oil circulates naturally. Heat rises through the radiators. This process cools the oil effectively. A conservator tank is usually fitted. This holds extra oil. It allows for oil expansion and contraction.

Protective features are important. A pressure relief device is standard. This vents excess pressure safely. An oil level gauge shows the oil volume. A thermometer monitors oil temperature. These features help prevent damage. They ensure safe operation. The unit is built for outdoor use. It withstands weather conditions. The enclosure protects internal parts.

Applications of 50KVA Oil-immersed Three-phase Power Transformer

This 50kVA oil-immersed three-phase transformer is a workhorse for reliable power distribution. It handles significant electrical loads safely and efficiently. Its oil cooling system absorbs heat generated during operation. This keeps temperatures stable and protects internal components. This design allows continuous duty in demanding environments.

Factories and workshops frequently use this transformer. It steps down higher voltage from the utility grid. This provides safer, usable voltage for machinery and lighting. It powers motors, assembly lines, and other heavy industrial equipment. Consistent voltage regulation is crucial here. This transformer delivers that stability.

Small towns and rural areas benefit greatly from this unit. It helps distribute power effectively over longer distances. Substations often deploy these transformers. They convert transmission voltage down for local distribution lines. This brings reliable electricity to homes and small businesses. It supports essential community services.

Construction projects need temporary, robust power. This transformer is ideal for these sites. It connects to temporary power grids. It supplies the necessary voltage for tools and site offices. Its rugged oil-filled tank resists dust and moisture. This ensures reliable operation outdoors.

Renewable energy sites also use this transformer. Small solar farms or wind installations generate power. This transformer steps up that voltage for connection to the grid. It also steps down incoming grid power for site use. It acts as a vital interface point.

5 FAQs of 50KVA Oil-immersed Three-phase Power Transformer

What is a 50kVA oil-immersed three-phase transformer?
It’s a big electrical box. It changes high voltage electricity to lower voltage electricity. Oil surrounds the internal parts. This oil cools everything. Three-phase means it handles heavy industrial power loads. 50kVA shows its power capacity.

Why use oil inside?
Oil does two main jobs. First, it cools the transformer windings and core. Electricity makes heat. The oil absorbs this heat. Second, oil insulates the parts. It stops dangerous electrical sparks. This keeps the transformer safe and working longer.

Where is this transformer usually installed?
You find these outdoors. They sit on concrete pads or special platforms. They power factories, workshops, farms, and large buildings. They feed power to machines, lighting, and other heavy equipment needing three-phase power. They connect to the main power grid.

How often does it need maintenance?
Check it regularly. Look at the oil level monthly. Test the oil quality yearly. Professionals should do this testing. Inspect for leaks or damage often. Keep the area around it clear. Major internal checks happen less often. Follow the manufacturer’s schedule exactly.

What’s important for safe installation?
Place it on a solid, level base. Ensure good air flow around it. Keep it far from buildings or flammables. Ground it properly. This is critical for safety. Only qualified electricians should connect the wiring. Follow all local electrical codes and safety rules.
