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.

• 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.

Specifikationer for 50KVA 100KVA 150KVA 200KVA 250KVA 300KVA 400KVA 450KVA 500KVA 20KV Olie nedsænket elektrisk kraftfordelingstransformator

These transformers step down 20kV circulation voltage to functional 400V or 415V degrees. They are crucial devices for delivering power securely to factories, bygninger, og store centre. The core and windings sit inside a durable steel tank loaded with specialized insulating oil. This oil cools the transformer and stops electric malfunction.

Criterion key voltage is 20,000 volt. Additional voltage is normally 400 volt eller 415 volt. The frequency is 50Hz or 60Hz, depending upon regional needs. Cooling down relies upon the ONAN technique. This implies the oil circulates normally inside the storage tank. Warmth transfers to the air via outside cooling fins or radiators.

Effektivitet er vigtigt. Lots losses and no-load losses are lessened. Greater kVA models normally accomplish far better efficiency numbers. Expect performance ratings between 97% og 99% for these devices. Actual efficiency depends upon the details tons account. Sound levels are maintained reduced. Sound pressure is generally below 55 decibels determined at 1 meter.

Physical dimension and weight boost considerably with kVA rating. A 50kVA unit might evaluate around 500kg. A 500kVA unit can exceed 3000kg. All transformers consist of important security devices. Stress safety valve protect against interior mistakes. Temperature level indications check oil and winding warmth degrees. Transformers above 250kVA generally include Buchholz relays. These identify gas buildup from interior arcing.

Installation needs a strong, degree concrete pad. Correct grounding is obligatory. Regular oil screening and upkeep guarantee lengthy service life. These transformers are developed for trustworthy procedure. They manage constant task under differing tons conditions. Environmental management fulfills IP55 requirements. This defend against dust and water jets. Efficiency abides by pertinent IEC criteria.

These oil-filled transformers step down 20kV power for day-to-day usage. Their durable design takes care of requiring atmospheres accurately. Various sizes fit specific power demands.

The smaller sized 50kVA and 100kVA units function well for stores, small factories, or farms. They power necessary illumination, værktøjer, and equipment without taking much space. Assume small workshops or water pumps. The 150kVA size supplies a little bit a lot more capability. It matches bigger retail areas, bigger workshops, or little business buildings requiring regular power.

Bevæger sig op, the 200kVA and 250kVA transformers take care of considerable lots. They prevail in medium manufacturing facilities, bigger commercial facilities, or institutions. They accurately run multiple machines, cooling and heating systems, and lights circuits. The 300kVA system provides a lot more power. It fits well in producing plants, healthcare facilities needing backup, or multi-story office complex. It keeps crucial operations running efficiently.

For sturdy needs, the 400kVA and 450kVA transformers provide serious power. They sustain big commercial centers, large hospitals, or major building and construction sites. These units handle heavy machinery, big motors, and intricate electric systems without stress. The biggest 500kVA transformer tackles the most significant tasks. It powers big factories, major information centers, or significant mining operations. It’s also used in neighborhood substations distributing power to areas or commercial parks.

All these transformers utilize oil for cooling and insulation. This makes them tough and long-lasting, especially outdoors or in severe conditions. They form the reliable backbone of power distribution. They securely convert high voltage right into useful power for many applications.
