Overview of 50kva 100kva 150kva 200kva 250kva 300kva 400kva 450kva 500kva 20kv Oil Immersed Electrical Power Distribution 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 50kva 100kva 150kva 200kva 250kva 300kva 400kva 450kva 500kva 20kv Oil Immersed Electrical Power Distribution 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.

It handles power from 50,000 watt (50kVA) opp til 500,000 watt (500kVA). The 20kV rating means it connects to a 20,000-volt power line. Oil inside cools it and provides electrical insulation.

Hvor brukes denne transformatoren vanligvis?
You see these transformers in many places needing reliable power distribution. They work well for industrial plants, large commercial buildings like shopping malls, sykehus, datasentre, utility substations, og boligutbygginger. They handle the significant power demands of these locations efficiently.

How should it be installed safely?
Installasjonen krever nøye planlegging. Place the transformer on a strong, nivå betongpute. Ensure good airflow around it for cooling. Keep it away from things that can burn. Only trained electricians should connect the high-voltage cables. Follow all local electrical codes and safety rules exactly. Grounding the transformer properly is critical for safety.

Hvilket vedlikehold krever det?
Regular checks keep it running reliably. Inspiser oljenivået ofte. Se etter lekkasjer rundt tanken og foringene. Test the oil quality periodically to check its insulating strength. Clean the outside surfaces to prevent dirt buildup. Listen for unusual noises like humming or cracking. Schedule professional inspections yearly or as the manufacturer recommends.

Hvor effektiv er denne transformatoren?
These oil-filled transformers are designed for good efficiency. They lose very little power during normal operation. Higher kVA models (like 400kVA or 500kVA) often run more efficiently under heavy loads than smaller ones. Less wasted energy means lower electricity costs over the transformer’s long life. Energy efficiency is a key benefit.
