Oversigt over 400 Kva 500kva 630 Kva 1500 Kva 3 Fase olie nedsænket distributionstransformer

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.

Funktioner af 400 Kva 500kva 630 Kva 1500 Kva 3 Fase olie nedsænket distributionstransformer

• 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.
