Overview of 20kv 50kva 100kva 150kva 200kva 250kva 300kva 400kva 450kva 500kva Oil Immersed Electrical Power Distribution 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 20kv 50kva 100kva 150kva 200kva 250kva 300kva 400kva 450kva 500kva Oil Immersed Electrical Power Distribution 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.

Applications of 20kv 50kva 100kva 150kva 200kva 250kva 300kva 400kva 450kva 500kva Oil Immersed Electrical Power Distribution Transformer

Oil-immersed electrical power circulation transformers take care of voltages as much as 20kV. They are available in sizes from 50kVA to 500kVA. These systems tip down high voltage power for day-to-day usage. They are common in position requiring reliable power distribution.

Factories use these transformers for heavy machinery. They power motors and production line. A 150kVA model matches medium manufacturing facilities. Larger plants might select 300kVA or 400kVA devices. Building and construction websites depend on them also. They supply short-lived power for devices and lights. A 100kVA transformer typically functions right here.

Commercial buildings depend upon these transformers. Shopping malls utilize 200kVA or 250kVA kinds. They run escalators and a/c. Medical facilities select 500kVA transformers for essential systems. They keep life-saving equipment running.

Rural electrification tasks set up these transformers. They bring power to towns. A 50kVA device serves little areas. Bigger communities need 450kVA transformers.

Oil cooling makes these transformers long lasting. They manage heat well throughout lengthy procedures. The oil likewise protects inner components. This protects against electrical failures. Maintenance is uncomplicated. Technicians check oil degrees and links regularly.

These transformers function outdoors. They stand up to rain and wind. Substations put them on concrete pads. Farms utilize them for irrigation pumps. A 100kVA design powers water supply.

Energies release them throughout power grids. They minimize voltage for neighborhood supply. A 200kVA transformer feeds a number of roads. Cities use multiple 300kVA units for broader coverage.

Oil-immersed transformers are economical. They last over 25 years with appropriate treatment. Industries choose them for consistent performance. They operate silently and need little space.

5 FAQs of 20kv 50kva 100kva 150kva 200kva 250kva 300kva 400kva 450kva 500kva Oil Immersed Electrical Power Distribution Transformer

Hva er egentlig denne transformatoren?
This is an oil-filled power distribution transformer. It handles high voltage electricity at 20,000 volt. It steps down this voltage for safe use in factories, bygninger, eller byer. We offer sizes from 50kVA to 500kVA.

Er det trygt?
Ja. It meets strict international safety rules (som IEC 60076). The special oil inside does two jobs. Det kjøler transformatoren. It also insulates the electrical parts. The strong steel tank protects everything inside. Sikkerhetsfunksjoner som trykkavlastningsventiler er standard.

Where can I put it?
You can install it indoors or outdoors. For outdoor use, it needs a solid concrete pad. Keep enough space around it for air to flow. This helps it stay cool. Make sure the area is clean and dry. Protect it from floods or heavy pollution.

Hvor lenge vil det vare?
With proper care, it lasts over 25 år. The key is regular, simple checks. Look at the oil level gauge often. Hold utsiden ren. Watch for leaks. Lytt etter uvanlige lyder. Check the temperature. We provide a full maintenance guide.

Can it handle overloads?
It handles short overloads well. The oil cooling helps with this. But don’t run it overloaded for long periods. This causes too much heat. Too much heat damages the insulation. This shortens the transformer’s life. Always size it correctly for your normal load.
