220kv Oil-immersed Low Loss 200 Mva Power Transformer

Overview of 220kv Oil-immersed Low Loss 200 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 220kv Oil-immersed Low Loss 200 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.

Specifications of 220kv Oil-immersed Low Loss 200 Mva Power Transformer

This 220kV oil-immersed power transformer handles large amounts of electricity. Its core rating is 200 MVA. It connects to high-voltage networks operating at 220 kilovolts. Oil surrounds the core and windings. This oil cools the transformer and provides insulation. The design specifically targets low energy loss during operation. This saves power and reduces operating costs significantly.

The transformer uses high-grade electrical steel for its core. This steel minimizes energy wasted as heat. The core is carefully stacked and clamped. This construction prevents vibration and noise. The windings are made from copper conductors. Copper offers excellent conductivity. The windings are arranged precisely. This arrangement ensures stable voltage output and good short-circuit strength. The entire core and coil assembly sits inside a strong steel tank. This tank holds the insulating oil.

High-voltage bushings connect the windings to the overhead lines. These bushings are designed for reliable 220kV service. They seal tightly against the tank. The transformer includes essential accessories. It has an oil conservator tank. This tank allows the oil to expand and contract with temperature changes. A silica gel breather keeps moisture out of the oil. A pressure relief device protects the tank from internal overpressure. Gauges monitor oil level and temperature constantly.

The low-loss design achieves high efficiency. Less energy is converted into wasted heat. This translates directly to lower electricity bills for the owner. The transformer operates reliably under demanding conditions. It handles the electrical stresses of the 220kV grid. Its robust construction ensures a long service life. Proper maintenance keeps it running efficiently for decades. This transformer is a key component for transmitting bulk power efficiently and reliably.

5 FAQs of 220kv Oil-immersed Low Loss 200 Mva Power Transformer

What does this transformer do?
This transformer moves electricity over long distances. It steps down high voltage power from 220,000 volts to safer levels for local grids. Its job is to handle large amounts of electricity efficiently. It connects major transmission lines to distribution networks.

Why use oil inside it?
The transformer tank is filled with special cooling oil. This oil absorbs heat generated during operation. It stops the internal parts from getting too hot. The oil also provides electrical insulation. This prevents dangerous short circuits inside the unit. It keeps everything running safely and reliably.

What does “200 MVA” mean?
200 MVA is the transformer’s power capacity. MVA stands for Mega Volt-Amperes. It shows the maximum load the transformer can handle continuously. This unit can manage 200 million volt-amperes. It is built for heavy-duty use in substations feeding large areas or industries.

What makes it “Low Loss”?
“Low Loss” means the transformer wastes very little power. Its core uses advanced magnetic steel. Its windings are designed precisely. This reduces energy lost as heat during voltage transformation. Less wasted energy means lower operating costs. It also means better efficiency over its lifetime.

How much maintenance does it need?
Regular checks are essential. Technicians monitor oil levels and quality. They test insulation strength. They inspect bushings, connections, and cooling systems. Major internal work requires special equipment and trained crews. Good maintenance prevents failures and extends its service life significantly.
