Regulating 250kva 3 Phase Control Electric Whole Outdoor Oil Immersed Distribution Transformer

Overview of Regulating 250kva 3 Phase Control Electric Whole Outdoor Oil Immersed 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 Regulating 250kva 3 Phase Control Electric Whole Outdoor Oil Immersed 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 Regulating 250kva 3 Phase Control Electric Whole Outdoor Oil Immersed Distribution Transformer

This 250kVA 3-phase transformer manages electricity flow. It steps down high voltage power to safer, usable levels for businesses or factories. The transformer is built for outdoor use. It handles tough weather conditions well.

The core and coils sit inside a strong steel tank. This tank is filled with special insulating oil. The oil cools the transformer. The oil also insulates the internal parts. This design prevents overheating during normal operation. The transformer works efficiently under load.

Its main job is regulating voltage. It keeps output voltage stable even when input voltage changes slightly. This protects sensitive equipment downstream. The transformer has taps on the high-voltage side. These taps allow small voltage adjustments. Technicians set these taps during installation.

The transformer uses mineral oil insulation. This oil is highly effective. The tank is sealed to prevent leaks. A conservator tank manages oil expansion and contraction. A breather keeps moisture out of the oil. This extends the transformer’s life.

Safety is important. The tank has a pressure relief device. This device vents excess pressure quickly. It prevents dangerous tank ruptures. The transformer meets strict safety standards. It has bushings for cable connections. These bushings are designed for high voltage.

Installation is straightforward. Mount it on a solid concrete pad. Connect the high-voltage lines. Connect the low-voltage lines. Ground the tank properly. Perform standard electrical checks. The unit is ready for service. Regular visual inspections are recommended. Check oil levels periodically. Listen for unusual noises. This ensures reliable operation for years. The transformer is built for durability. It requires minimal maintenance.

Applications of Regulating 250kva 3 Phase Control Electric Whole Outdoor Oil Immersed Distribution Transformer

This transformer manages electricity flow for large operations. It handles 250,000 volt-amperes of power. It works with three-phase systems common in businesses and industry. The transformer sits outdoors. It uses oil for cooling and insulation. The oil circulates inside a strong metal tank. This tank protects the transformer parts. The oil keeps things cool during operation. It also prevents electrical shorts. This design is very reliable. It lasts a long time even in tough weather.

The transformer changes voltage levels. It steps down high incoming voltage. It provides safer, usable voltage for equipment. This is essential for factories, farms, and big buildings. It ensures machines get stable power. Stable power prevents damage to motors and devices. The transformer regulates voltage automatically. It keeps the output voltage steady. This happens even when the power load changes. Fluctuations in demand won’t cause problems.

Its outdoor design saves valuable indoor space. You install it near the point of use. This reduces power loss over long wires. Less power loss saves money. The oil-immersed construction is low maintenance. It handles heavy use continuously. Safety features are built-in. These features protect against overloads and faults. The transformer connects directly to power lines. It distributes power efficiently across a site. This setup powers entire facilities reliably. It prevents costly downtime. Businesses depend on this consistent performance. It handles the core power distribution job well.

5 FAQs of Regulating 250kva 3 Phase Control Electric Whole Outdoor Oil Immersed Distribution Transformer

What exactly is this transformer?
This unit controls electricity flow. It handles 250kVA power. It uses three-phase current. The core and windings sit inside a tank filled with oil. This oil cools everything. It’s built for outdoor use. Tough weather won’t hurt it. It steps down high voltage for buildings or factories.

How much space does it need outside?
Leave enough room around it. This is vital for air flow. It keeps the transformer cool. You need space for safe operation too. Workers must access it easily. Check the manual for exact distances. The base must be strong and perfectly level. A concrete pad is best. Secure it properly to the base.

Can rain or snow damage it?
No, it’s built for harsh weather. The enclosure has a high IP rating. This means strong protection against water and dust. The design includes features to stop water getting in. Ensure the site has good drainage. Water must not pool around the base. Regular checks for leaks are smart.

How often does it need maintenance?
Schedule yearly inspections at least. Trained people should do this. They check the oil level and quality. They look for leaks or damage. They test the connections and bushings. Oil samples might be tested in a lab. This finds problems early. Follow the maker’s maintenance plan closely.

What safety features does it have?
Safety is critical. It has a pressure relief device. This vents the tank if internal pressure gets too high. It prevents dangerous explosions. An oil level gauge shows if oil is low. Many units have alarms for high temperature or low oil. Ground the transformer correctly. This protects people and equipment.
