En olie-nedsænket transformer er en type elektrisk transformer, hvor kernen og viklingerne er nedsænket i en isolerende olie. Denne olie tjener to primære funktioner: det fungerer som en yderst effektiv isolator mellem ledende dele og som et kølemiddel til at sprede varme genereret under drift. Disse transformere er robuste, pålidelig, og yderst effektiv, hvilket gør dem til standardvalget for højspændingsstrømdistributions- og transmissionsnetværk, typisk installeret udendørs i transformerstationer.

• Effektiv køling: Den isolerende olie absorberer effektivt varme fra kernen og viklingerne og overfører den til radiatorfinnerne, giver mulighed for naturlig eller tvungen cirkulation og højere overbelastningskapacitet.
• Overlegen isolering: Olien giver meget bedre dielektrisk styrke end luft, giver mulighed for et mere kompakt design for en given spændingsværdi og beskytter mod kortslutninger.
• Robust konstruktion: Designet til langsigtet, pålidelig drift (ofte 25-30 år) i barske udendørsmiljøer.
• Overbelastningskapacitet: Kan håndtere midlertidige strømoverbelastninger bedre end transformatorer af tør type på grund af oliens termiske masse og køleegenskaber.
• Beskyttelsessystem: Udstyret med konservatortank (for at give mulighed for olieudvidelse), åndedræt (at absorbere fugt fra luften), og beskyttelsesrelæer (Buchholz stafet) til intern fejlsøgning.
• Omkostningseffektiv: Generelt mere økonomisk til højeffektapplikationer sammenlignet med transformatorer af tør 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, og 330MVA. De er bygget til trefasede 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. Mulighederne inkluderer ONAN (olie-naturlig, luft-naturlig) or ONAF (olie-naturlig, lufttvunget) systemer. Larger units often use forced cooling.

The core uses top-quality grain-oriented silicon steel. This reduces magnetic losses significantly. Vindingerne er kobber eller aluminium. De er omhyggeligt isolerede. 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 transformere er hårde. 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. Regelmæssig vedligeholdelse er afgørende. 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.

Anvendelser af trefaset 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. Capacities like 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.
