Elektriske transformatorer med lavt tap trefaset oljenedsenket distribusjonskrafttransformator 20kva-5MVA

Overview of Electric Transformers Low Loss Three Phase Oil Immersed Distribution Power Transformer 20kva-5MVA

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 Electric Transformers Low Loss Three Phase Oil Immersed Distribution Power Transformer 20kva-5MVA

• 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.

5 FAQs of Electric Transformers Low Loss Three Phase Oil Immersed Distribution Power Transformer 20kva-5MVA

Here are five common questions about our low loss three phase oil immersed distribution power transformers (20kva-5MVA):

Hva gjør denne transformatoren “lavt tap”?
Our design significantly cuts down wasted energy. We use top quality grain-oriented silicon steel for the core. This reduces no-load loss. No-load loss happens when the transformer is plugged in but not powering equipment. We also optimize the windings. This lowers load loss. Load loss occurs during actual power delivery. Lower losses mean lower electricity bills over the transformer’s life.

Hvilket kapasitetsområde dekker disse transformatorene?
We offer these transformers from 20 kilovolt-ampere (kVA) opp til 5 megavolt-amperes (MVA). This range suits many distribution needs. Common uses include powering factories, næringsbygg, housing complexes, and renewable energy connection points. Tell us your specific voltage and power requirements. We find the right size unit for you.

Hvordan er denne transformatoren installert?
Installasjonen krever nøye planlegging. The transformer arrives filled with insulating oil. It is heavy. Ensure your site has a strong, nivå fundament. Proper lifting equipment is essential. Connect the high voltage and low voltage terminals correctly. Follow all safety codes. Qualified electrical personnel must handle installation and commissioning. We provide detailed installation manuals.

Hvilket vedlikehold som kreves?
Regular checks keep the transformer reliable. Visually inspect the tank for leaks. Monitor the oil level using the gauge. Check the oil temperature. Sample the insulating oil periodically. Lab analysis finds moisture or breakdown products. Clean the radiators to prevent overheating. Keep the area around the transformer clear. Follow the maintenance schedule in the manual. Større internt arbeid trenger spesialister.

Er disse transformatorene trygge?
Sikkerhet er kritisk. The robust steel tank protects the core and windings. The insulating oil cools the unit. Det forhindrer også elektrisk lysbue. Units include a conservator tank. This allows oil to expand and contract safely. A breather stops moisture entering the oil. Pressure relief devices guard against internal faults. Buchholz relays detect gas from internal problems. They trigger an alarm or shutdown. Always follow electrical safety procedures.
