Three Phase Oil Immersed 4000 KVA 4 MVA Power Transformer

Overview of Three Phase Oil Immersed 4000 KVA 4 MVA 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 Three Phase Oil Immersed 4000 KVA 4 MVA 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.

5 FAQs of Three Phase Oil Immersed 4000 KVA 4 MVA Power Transformer

Three Phase Oil Immersed 4000 KVA / 4 MVA Power Transformer: Your Questions Answered

What exactly is this transformer?
This is a big power transformer. It handles 4000 KVA or 4 MVA of electrical power. It uses three-phase electricity. The transformer sits inside a tank filled with special insulating oil. This oil cools the transformer. It also provides electrical insulation.

Where is this transformer used?
You find this transformer in places needing lots of power. It works well in factories, big buildings, power plants, and substations. It steps high voltage electricity down to safer, usable levels. Sometimes it steps voltage up for transmission over long distances.

How does the cooling work?
The insulating oil absorbs heat from the transformer core and windings. The hot oil naturally rises to the top of the tank. Cooler oil sinks to the bottom. This creates a natural flow. Larger transformers might have external radiators. Fans blow air over these radiators to help cool the oil faster.

What voltage levels does it handle?
The exact input and output voltages depend on your specific needs. These transformers are custom-built for the job. Common high voltage inputs might be 11kV, 33kV, or 66kV. Common low voltage outputs are often 400V, 6.6kV, or 11kV. You must tell the manufacturer your required voltages.

Is it safe?
Ja, safety is built in. The oil insulation is a key safety feature. The tank is strong and sealed. Pressure relief devices protect against internal faults. Temperature gauges monitor the oil. Specific safety devices detect internal problems like gas build-up. They stop major damage. Regular maintenance checks are essential for long-term safety.
