Trefaset olie nedsænket 4000 KVA 4 MVA Power Transformer

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

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.

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

• 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.

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 (Olie Naturlig Luft Naturlig). This is simple and trustworthy.

Kernen er lavet af topkvalitets siliciumstål. 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, eller 33kV. Secondary could be 0.415 kV, 3.3 kV, 6.6 kV, eller 11kV. Andre spændinger er mulige. 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 (Grundlæggende impulsniveau) er høj. This shields against voltage rises.

Transformatoren kører stille og roligt. 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, industriparker, or large business complexes. This makes certain power reaches end-users efficiently and safely.

Industries depend on these durable transformers. Fremstillingsfaciliteter, kemiske anlæg, miner, and huge manufacturing centers need steady, høj kapacitet strøm. De 4000 KVA system supplies the necessary change point within their interior electric systems. It powers hefty equipment, store elmotorer, 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. Solparker og vindafdrag skaber strøm, 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. Lufthavnsterminaler, havne, sundhedscentre, 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.
