11 13 14 MVA 12500 KVA 13000kVA 3 Phase Electrical Oil Immersed Power Transformer

Overview of 11 13 14 MVA 12500 KVA 13000kVA 3 Phase Electrical Oil Immersed Power Transformer

En oljenedsenket transformator er en type elektrisk transformator der kjernen og viklingene er nedsenket i en isolerende olje. Denne oljen har to hovedfunksjoner: den fungerer som en svært effektiv isolator mellom ledende deler og som et kjølemiddel for å spre varme som genereres under drift. Disse transformatorene er robuste, pålitelig, og svært effektiv, gjør dem til standardvalget for distribusjons- og overføringsnett med høyspent kraft, vanligvis installert utendørs i transformatorstasjoner.

Features of 11 13 14 MVA 12500 KVA 13000kVA 3 Phase Electrical Oil Immersed Power Transformer

• Effektiv kjøling: Den isolerende oljen absorberer effektivt varme fra kjernen og viklingene og overfører den til radiatorfinnene, gir mulighet for naturlig eller tvungen sirkulasjon og høyere overbelastningskapasitet.
• Overlegen isolasjon: Oljen gir mye bedre dielektrisk styrke enn luft, muliggjør en mer kompakt design for en gitt spenningsklassifisering og beskytter mot kortslutninger.
• Robust konstruksjon: Designet for langsiktig, pålitelig drift (ofte 25-30 år) i tøffe utemiljøer.
• Overbelastningskapasitet: Kan håndtere midlertidige strømoverbelastninger bedre enn transformatorer av tørr type på grunn av oljens termiske masse og kjøleegenskaper.
• Beskyttelsessystem: Utstyrt med konservatortank (for å tillate oljeutvidelse), pusterom (å absorbere fuktighet fra luft), og beskyttelsesreléer (Buchholz stafett) for intern feildeteksjon.
• Kostnadseffektiv: Generelt mer økonomisk for høyeffektapplikasjoner sammenlignet med transformatorer av tørr type.

Pressure alleviation gadgets shield versus internal mistakes.

These transformers satisfy IEC 60076 criteria. Standard Impulse Degree (BIL) holds up against lightning strikes and surges. They include tap changers. Off-circuit faucet changers adjust voltage during shutdown. On-load faucet changers (valgfri) adjust voltage while running. Bushings attach the transformer to the power lines. They are porcelain or composite, rated for the system voltage.

The transformers are made for long life. They run reliably in demanding conditions. Trick applications include substations, plants, and renewable energy ranches. They tip down voltage from transmission lines for local usage. They likewise interconnect various areas of the power grid.

Applications of 11 13 14 MVA 12500 KVA 13000kVA 3 Phase Electrical Oil Immersed Power Transformer

These oil-filled power transformers deal with big electrical energy jobs. They manage power between 11,000 og 33,000 volt. You see them inside substations near cities and factories. They take high voltage from the primary grid lines. They step it down to safer degrees. Manufacturing facilities and communities after that utilize this power securely.

Manufacturing facilities require lots of consistent power. Steel mills, chemical plants, large producers rely on these transformers. Makers like big motors and heaters demand consistent voltage. These 11, 13, 14 MVA units supply that power dependably. They keep hefty commercial processes running smoothly. Power failures cost money below.

Renewable resource farms make use of these transformers too. Big solar parks or wind farms produce power. This power usually heads out at medium voltage. The transformers enhance this voltage. They push the power successfully onto the high-voltage transmission grid. Less energy gets shed over fars away in this manner. This makes eco-friendly power projects functional.

The oil inside is important. It cools the transformer’s core and coils. It additionally offers important insulation. This design manages high electric tons safely. It prevents unsafe overheating. These transformers work constantly for years. They endure difficult problems. Støv, temperature modifications, and moisture are common. The oil protects the inner parts.

These rankings (11, 13, 14 MVA, 12500kVA, 13000kVA) prevail. They provide the ideal power for lots of scenarios. They link smaller circulation transformers and massive grid devices. Utilities and industries trust fund this dimension. They understand it supplies reliable efficiency. They create an important web link in the power chain.

5 FAQs of 11 13 14 MVA 12500 KVA 13000kVA 3 Phase Electrical Oil Immersed Power Transformer

Here are 5 common questions about 11, 13, 14 MVA (12500kVA, 13000kVA) oil-immersed power transformers:

What capacity range do these transformers cover?
These transformers handle large power loads. They come in 11 MVA (11,000 kVA), 13 MVA (13,000 kVA), og 14 MVA (14,000 kVA) sizes. This covers needs like 12500 kVA and 13000 kVA. They move significant electricity for industrial sites or substations.

What voltages do they handle?
They manage high transmission and distribution voltages. Primary voltages are often 33 kV, 66 kV, eller 110 kV. Secondary voltages are commonly 6.6 kV, 11 kV, eller 33 kV. The exact voltages are custom ordered for the specific project requirements.

How does the oil cooling work?
The transformer core and windings sit inside a tank filled with special insulating oil. This oil absorbs heat generated during operation. The heated oil naturally rises. It flows through radiator banks or cooling fins attached to the tank. Air cools the oil there. The cooled oil sinks back down. This cycle keeps the transformer at a safe operating temperature.

Where are these transformers typically used?
You find them in demanding electrical networks. They are common in primary substations receiving power from the grid. Large factories, processing plants, and heavy industries use them. Mines and large commercial complexes also rely on these units. They step down high incoming voltage to usable levels for the facility.

What standards ensure safety and performance?
They meet strict international and local rules. Key standards include IEC 60076 and IEEE C57. These cover design, testing, safety, and efficiency. Manufacturers follow these standards. This ensures reliable, safe operation over a long lifespan.
