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

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. Vedligeholdelse er ukompliceret. 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.

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

Hvad er denne transformer helt præcist?
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 sikkert?
Ja. It meets strict international safety rules (ligesom IEC 60076). The special oil inside does two jobs. Det køler transformeren. It also insulates the electrical parts. The strong steel tank protects everything inside. Safety features like pressure relief valves are 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. Sørg for, at området er rent og tørt. Protect it from floods or heavy pollution.

Hvor længe vil det vare?
With proper care, it lasts over 25 år. The key is regular, simple checks. Look at the oil level gauge often. Keep the outside clean. Hold øje med lækager. Lyt efter usædvanlige lyde. 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.
