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

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

• 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.

All units operate at a primary voltage of 20kV. The secondary voltage is commonly 400V or 415V. This suits standard power distribution needs. The design is robust for continuous duty.

The core uses high-grade grain-oriented silicon steel. Dette minimerer energitab. Viklinger er kobberledere. Kobber giver fremragende ledningsevne. The core and windings sit inside a welded steel tank. The tank is filled with high-quality insulating mineral oil. This oil insulates and cools the transformer. Radiatorer fastgøres til tanken. Radiators increase the cooling surface area. Natural oil circulation provides cooling. Larger units might need fans.

Standard vector group is Dyn11. This allows parallel operation with others. Impedance voltage typically falls between 4% og 6%. This ensures good short-circuit protection. Støjniveauet er lavt. Noise stays below standard limits. The tank includes a conservator. The conservator holds extra oil. Oil volume changes with temperature. A breather protects the oil. The breather keeps moisture out. Silica gel absorbs moisture inside the breather.

Bushings are porcelain or polymer. Bushings connect the high and low voltage cables. An oil level indicator shows the oil position. A pressure relief device prevents tank damage. This device vents if pressure gets too high. All transformers have lifting lugs. Lifting lugs make moving easier. Earthing terminals are standard. Terminals ensure safe grounding.

No-load losses and load losses meet efficiency standards. Loss values depend on the specific kVA rating. Higher kVA models weigh more. Weight increases significantly with capacity. The transformer withstands normal short circuits. The design includes safety margins. Units are tested rigorously before shipping. Tests confirm performance and safety.

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

These oil-immersed transformers handle 20kV primary voltage. They are vital for getting power where it’s needed safely. The 50kVA and 100kVA models suit smaller operations. Tænk små fabrikker, værksteder, or groups of shops. They step down voltage for machines and lighting reliably. They are compact and tough for these everyday jobs.

The 150kVA and 200kVA units serve bigger demands. They power larger commercial buildings like shopping centers or office blocks. Hospitals and schools often rely on these sizes too. They manage the constant power needs of many people and systems. Their oil cooling keeps them stable during long hours.

Need serious power? Look at the 250kVA and 300kVA transformers. Heavy industrial settings use them. Think production lines with big motors or large processing equipment. They deliver consistent voltage under heavy loads. Their robust build handles the tough factory environment.

De største enheder, 400kVA, 450kVA, og 500kVA, are for major projects. Big factories with intensive machinery need this capacity. They might feed entire sections of a plant. These transformers also work well in dedicated power substations. They serve as key distribution points for wider areas. Renewable energy sites, like solar farms, often use them to connect to the grid. Their high capacity and 20kV rating make them versatile power hubs. The oil insulation provides excellent cooling and electrical protection. This ensures long life and dependable operation. Choosing the right kVA size matches the specific power load requirement.

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

Her er 5 common questions about our 50kVA to 500kVA Oil Immersed Distribution Transformers (20kV):

What do these transformers actually do?
They safely step down 20kV high voltage electricity to lower voltages suitable for factories, bygninger, eller kvarterer. They handle power from 50,000 til 500,000 volt-ampere.

How do I pick the right size transformer?
Calculate your total electrical load. Add up the power needs of everything connected. Pick a transformer size larger than your calculated load. This gives room for future growth. Our team helps with sizing calculations.

Why do they use oil?
The oil inside is crucial. It insulates the internal parts. It also cools the transformer. The transformer gets hot during operation. The oil carries this heat away to the tank walls. Dette holder transformeren kørende sikkert.

Where and how should I install one?
Install them outdoors. They need good air circulation. Mount them on strong concrete pads. Keep them away from walls or other equipment. Følg de lokale elektriske regler nøjagtigt. Korrekt jording er afgørende for sikkerheden.

Hvilken vedligeholdelse er nødvendig?
Kontroller oliestanden regelmæssigt. Se efter lækager. Keep the exterior clean. Inspect bushings and connections periodically. Test the oil quality every few years. This finds any internal problems early. Følg producentens vedligeholdelsesplan.
