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.

• 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.

These transformers handle high voltage power transmission efficiently. They work at 35KV, 66KV, 110KV, 220KV, and 230KV levels. Power ratings range widely from 8MVA up to 330MVA. Common sizes include 8MVA, 10MVA, 12.5MVA, 20MVA, 25MVA, 40MVA, 63MVA, 100MVA, 250MVA, and 330MVA. De er bygget for trefase elektriske systemer.

These units step voltage up or down in substations and power grids. They connect generation plants to distribution networks. Their design prioritizes minimal energy loss. This saves operational costs over time. Efficient cooling is crucial. Options include ONAN (olje-naturlig, luft-naturlig) or ONAF (olje-naturlig, air-forced) systemer. Larger units often use forced cooling.

The core uses top-quality grain-oriented silicon steel. This reduces magnetic losses significantly. Viklinger er av kobber eller aluminium. De er nøye isolert. The transformer oil provides insulation and cooling. It must be kept clean and dry. Bushings safely connect the high voltage cables. Tap changers adjust the output voltage. This compensates for grid fluctuations. Load fluctuations are managed well.

Disse transformatorene er tøffe. They handle demanding grid conditions. They resist short circuits and overloads. Strict quality control happens during manufacturing. Tests include routine checks and special type tests. Impulse and temperature rise tests verify safety. Standards like IEC or IEEE are followed closely. This ensures reliability and long service life.

Installation needs proper planning. Foundations must support the heavy weight. Skilled technicians handle the oil filling and connections. Regelmessig vedlikehold er viktig. Oil testing checks insulation health. Visual inspections spot leaks or damage. Protective relays monitor operation constantly. They trigger shutdowns if problems occur. Technical support and spare parts are available. This guarantees continuous power supply.

Applications of Three Phase 35KV 66KV 110KV 220KV 230KV 8mva 10mva 12.5mva 20mva 25mva 40mva 63mva 100mva 250mva 330mva Mv&hv Power Transformer

Three phase power transformers handle high voltages like 35KV, 66KV, 110KV, 220KV, 230KV, and 330KV. They manage large amounts of power, rated from 8MVA up to 330MVA. These units are vital for moving electricity efficiently over long distances. They connect power plants to the grid and link different parts of the transmission network.

Transformers rated 35KV or 66KV are common in distribution networks. They step down voltage for local use. Kapasiteter som 8MVA, 10MVA, 12.5MVA, or 20MVA suit substations feeding towns or large industrial sites. Factories needing significant power often use these directly.

Higher voltages like 110KV involve transformers for sub-transmission. Units around 25MVA, 40MVA, or 63MVA are typical here. They move power from major substations closer to city centers before further stepping down.

The backbone of the grid uses 220KV, 230KV, and 330KV levels. These handle bulk power transfer across regions or countries. Large power plants connect through massive transformers. Sizes like 100MVA, 250MVA, or 330MVA are standard. They feed directly into the high-voltage transmission lines. Interconnecting separate power grids also requires these very large units.

Specific applications depend on the exact voltage and MVA rating. A 25MVA, 66KV transformer might serve a large factory. A 100MVA, 220KV unit connects a power station. A 250MVA or 330MVA, 330KV transformer is crucial for national grid interconnections. They minimize energy loss during transmission. Their reliability is critical for stable power supply everywhere. Utilities and industries rely on these transformers daily. They form the essential links moving electricity from generation to consumers.
