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.

Specifications of Three Phase Oil Immersed 4000 KVA 4 MVA Power Transformer

This transformer handles heavy industrial power demands. It’s ranked for 4000 KVA or 4 MVA. This indicates it handles big electric lots reliably. The three-phase design fits manufacturing facilities and huge facilities.

It utilizes oil for insulation and air conditioning. The oil circulates normally around the core and windings. This maintains temperatures safe during procedure. The air conditioning type is ONAN (Oil Natural Air Natural). This is simple and trustworthy.

The core utilizes top-quality silicon steel. This lowers power losses significantly. The windings are copper for reliable power transfer. They are very carefully scheduled stability. The entire assembly rests inside a solid, welded steel tank. This storage tank holds the protecting oil safely.

Common voltage ratings prevail. Main might be 11kV, 15kV, 22kV, or 33kV. Secondary could be 0.415 kV, 3.3 kV, 6.6 kV, or 11kV. Other voltages are possible. Resistance is normally around 6%, but it can be adjusted. This regulates fault currents efficiently.

Power losses are an essential emphasis. The layout lessens no-load loss and tons loss. This conserves cash over the transformer’s long life. Insulation course is generally Class A. The BIL (Basic Impulse Level) is high. This shields against voltage rises.

The transformer runs quietly. Sound levels are maintained low. Temperature level surge is limited. It stays well below safety margins. The tank consists of functions for easy upkeep. There’s an oil conservator, a rest, and a Buchholz relay. The relay identifies inner faults swiftly.

Extensive testing guarantees top quality. Each system passes regular checks. Type examinations and special examinations are also executed. Requirements like IEC 60076 or IEEE C57.12.00 are adhered to. This guarantees security and efficiency.

Applications of Three Phase Oil Immersed 4000 KVA 4 MVA Power Transformer

3 phase oil submersed 4000 KVA (4 MVA) power transformers deal with big electrical loads accurately. They are vital devices where substantial power distribution or voltage change is needed. Utilities use these transformers thoroughly. They step down high transmission voltages to much safer, reduced levels for neighborhood distribution networks feeding communities, industrial parks, or large business complexes. This makes certain power reaches end-users efficiently and safely.

Industries depend on these durable transformers. Manufacturing facilities, chemical plants, gruver, and huge manufacturing centers need steady, high-capacity power. De 4000 KVA system supplies the necessary change point within their interior electric systems. It powers hefty equipment, huge electric motors, and substantial handling lines without disturbance. Oil immersion successfully cools the transformer windings and core during continual durable procedure.

Renewable energy tasks also utilize these transformers. Solar farms and wind installments create power, usually at tool voltage levels. De 4000 KVA transformer boosts this voltage for efficient transmission over longer ranges to the primary grid connection factor. This reduces power losses during transportation.

Huge facilities jobs require trustworthy power circulation. Airport terminals, ports, health centers, university schools, and significant information facilities all have considerable electricity needs. These transformers develop vital nodes within their dedicated electric circulation grids, making certain constant power circulation to vital systems and structures. They are frequently set up in substations on-site.

Their robust oil-immersed layout makes them ideal for requiring environments. They offer excellent security against overloads and supply steady operation over extended periods. This reliability is vital for mission-critical procedures. They likewise function as crucial parts in backup power systems for necessary centers.
