Oversikt over 3 Trefase 315 KVA 330kVA 350 KVA Hv Lv Oljenedsenket kraftfordelingstransformator

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.

Funksjoner av 3 Trefase 315 KVA 330kVA 350 KVA Hv Lv Oljenedsenket kraftfordelingstransformator

• 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.

Spesifikasjoner av 3 Trefase 315 KVA 330kVA 350 KVA Hv Lv Oljenedsenket kraftfordelingstransformator

Here are the specifications for 3 oil-immersed power distribution transformers: 315 kVA, 330 kVA, og 350 kVA. These are three-phase units made for stepping down high voltage to reduced voltage. They are built for dependable power distribution.

The main high voltage rating is generally 11,000 volt eller 33,000 volt. The secondary reduced voltage is typically 400 volt. Certain voltage combinations are readily available to satisfy project needs. These transformers utilize mineral oil for insulation and cooling. The oil flows normally around the core and windings. This ONAN cooling technique is typical and effective.

The core is made from high-grade, kornorientert silisiumstål. Dette minimerer energitap under drift. The windings are copper permanently conductivity and efficiency. They are meticulously prepared on the core. The entire energetic component sits inside a robust welded steel container. This tank holds the shielding oil. The container is sealed to keep wetness out.

Operating temperature restrictions are important. The typical winding temperature increase must not surpass 65 °C. The top oil temperature level increase need to not surpass 55 °C. These restrictions are determined above the ambient air temperature. The ambient temperature level is typically a maximum of 40 °C. The transformers satisfy standard efficiency levels. De følger IEC 60076 or comparable international requirements. Losses are kept low: no-load losses and tons losses are enhanced.

The transformers consist of crucial devices. There is an oil degree indicator on the container. A pressure relief tool shields versus interior over-pressure. A drain shutoff enables oil tasting or draining pipes. An earthing terminal is attended to safety and security. Raising lugs are fitted for risk-free handling throughout installment. These units are made for long life span. They handle requiring distribution atmospheres well.

These power transformers manage significant electrical energy requirements. They step down high voltage to safer, useful reduced voltage. This happens successfully inside their oil-filled storage tanks. The oil cools every little thing and stops electrical troubles.

Manufacturing facilities utilize these transformers daily. Large devices need trusted power. A 350kVA unit commonly feeds whole assembly line or big electric motor control centers. It maintains points running without voltage drops. Storehouses depend upon them as well. Lys, transportbånd, and packaging devices run smoothly.

Shopping mall and office buildings require them. These places utilize great deals of power for lights, klimaanlegg, og datamaskiner. A 315kVA or 330kVA transformer may power a whole area of a mall or a multi-story workplace block. It guarantees stores stay open and workplaces function right.

Building websites utilize them temporarily. Large jobs need momentary high-capacity power prior to the long-term grid connects. These transformers supply it safely. De driver kraner, cement mixers, and website offices up until the work finishes.

Water treatment plants count on them. Pumps and filtration systems run regularly. A 350kVA transformer provides the stable power these crucial facilities demand. Farms with big irrigation systems also use them. Big pumps moving water need robust power shipment.

These transformers are workhorses. They are constructed difficult for years of service. The oil insulation allows them to manage heavy tons consistently. They sit quietly in substations or on pads outside buildings. You discover them where considerable, trusted power distribution is non-negotiable. They create a crucial web link between the high-voltage grid and the equipment individuals actually make use of.

5 Vanlige spørsmål om 3 Trefase 315 KVA 330kVA 350 KVA Hv Lv Oljenedsenket kraftfordelingstransformator

What are these 315-350kVA oil transformers for?
These transformers take high voltage electricity from the grid. They step it down to safer, usable low voltage levels. Fabrikker, store bygninger, sykehus, and industrial sites use them for their main power distribution. They handle the heavy electrical loads these places need.

Hvordan fungerer oljekjølingen?
Transformatorkjernen og viklingene sitter inne i en sterk ståltank fylt med spesiell isolasjonsolje. This oil does two big jobs. It stops electrical arcs inside the transformer. It also pulls heat away from the core and windings. The heat moves to the oil. The oil then carries the heat to the tank walls. The tank walls release the heat into the surrounding air. Bigger models might have extra cooling tubes or radiators for more surface area.

What voltages can these transformers handle?
You can order them with different high voltage and low voltage combinations. Common HV inputs are 11kV, 22kV, eller 33kV. Common LV outputs are 400V, 415V, eller 480V. Tell us your specific incoming voltage and required output voltage. We build the transformer to match your exact site needs.

Er disse transformatorene trygge?
Ja, sikkerhet er innebygd. They follow strict international standards like IEC. The tank is very strong. Den holder oljen sikkert. Good models have pressure relief devices. Disse ventilerer trygt hvis det indre trykket blir for høyt. Temperature gauges monitor oil heat levels. They also have overload protection. This helps prevent damage if demand spikes unexpectedly.

What about installing one?
You need enough space. The site must be flat, stabil, and dry. Remember the transformer is heavy when full of oil. You need space around it for air to flow freely. This keeps cooling working right. You also need space for technicians to check oil levels, forbindelser, and do maintenance safely.
