High Performance 8 MVA 11 KV 0.4 KV Oil Immersed Transformer for Urban Distribution

Overview of High Performance 8 MVA 11 KV 0.4 KV Oil Immersed Transformer for Urban Distribution

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 High Performance 8 MVA 11 KV 0.4 KV Oil Immersed Transformer for Urban Distribution

• 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.

A conservator tank maintains oil quantity as temperatures alter. A Buchholz relay detects inner faults like gas bubbles. It causes an alarm system or closure. A pressure relief tool safeguards against harmful internal stress surges. Silica gel breathers maintain the oil completely dry.

The system makes use of ONAN air conditioning. This suggests Oil Natural Air Natural. Warmth increases naturally via the oil. The container’s surface area radiates warmth into the surrounding air. Outside radiators improve cooling down capability if required. This layout is basic and trustworthy.

The transformer has off-circuit tap changers. These readjust the result voltage somewhat. This compensates for differing grid problems. Level and temperature assesses monitor the oil quickly. Grounding terminals are robust and plainly significant.

This transformer masters efficiency. It meets stringent energy loss criteria. Noise degrees are reduced. This is vital for installments near structures or homes. Its compact impact matches space-limited urban substations. The durable building and construction makes sure a long service life. It deals with heavy loads reliably day and night.

Strenuous manufacturing facility testing assurances efficiency. Tests include resistance checks, proportion confirmation, and insulation resistance. Polarity and vector team tests validate proper phase connections. Applied and induced voltage tests show dielectric strength. Full tons tests show temperature rise limits. The system fulfills all IEC 60076 standards.

Applications of High Performance 8 MVA 11 KV 0.4 KV Oil Immersed Transformer for Urban Distribution

This transformer takes care of power in hectic city areas. It steps down 11,000 volts to safer 400 volts. This voltage is appropriate for shops, offices, and homes close by. Its 8 MVA dimension fits well for medium-density urban zones needing dependable power.

Cities have special power difficulties. Space is tight for tools. Power demand is high and maintains changing. This transformer is developed for these conditions. Its oil cooling down manages warmth effectively even during peak use times. This prevents overheating problems common in congested locations.

Reliability is critical in cities. Power failures trigger huge disruptions. This transformer makes use of proven oil-immersion technology. It safeguards interior components effectively. This design guarantees lengthy life and stable procedure. It handles everyday tons swings without trouble. This suggests less disruptions for consumers.

Safety and security is a major focus. The durable storage tank consists of the oil firmly. Special defense systems monitor stress and temperature level regularly. These systems activate alarm systems or closures if anything uncommon occurs. This avoids mishaps and secures the wider network.

Installment in cities is much easier with this design. Its physical impact is fairly portable. This matters where substation room is expensive and restricted. Maintenance is likewise straightforward. Technicians can easily access key parts for checks and solution. This maintains the transformer running efficiently for years.

The transformer supplies power effectively. Lower power losses suggest reduced operating expense. This profits the power company and eventually the consumer. It gives the solid, consistent electricity modern metropolitan life demands.

5 FAQs of High Performance 8 MVA 11 KV 0.4 KV Oil Immersed Transformer for Urban Distribution

What safety features protect this transformer?
The transformer has strong protection. Its oil system cools the core and windings. It also prevents overheating. Pressure relief devices guard against tank overpressure. Buchholz relays detect internal faults fast. They trigger alarms or shutdowns. Grounding points are clear and secure. This ensures operator safety during work.

How often does this transformer need maintenance?
Regular checks are essential. Oil quality and level require monitoring. Check them every six months. Inspect bushings, connections, and cooling radiators yearly. Full internal inspections happen less often. They depend on condition monitoring results. Follow the manufacturer’s schedule strictly. Keep detailed maintenance records.

Is this transformer quiet enough for city areas?
Yes, noise control is a priority. The core uses low-vibration silicon steel. The tank design minimizes sound transmission. Cooling fans operate quietly. The transformer meets strict urban noise limits. It works well near buildings and residential zones. Sound levels are tested and certified.
