En Ueleg-Taucht Transformator ass eng Zort elektreschen Transformator wou de Kär an d'Wicklungen an engem isoléierende Ueleg ënnergeet sinn. Dësen Ueleg déngt zwou primär Funktiounen: et handelt als héich effektiven Isolator tëscht konduktiven Deeler an als Kältemëttel fir d'Hëtzt, déi während der Operatioun generéiert gëtt, ze dissipéieren. Dës Transformatoren si robust, zouverlässeg, an héich efficace, mécht se de Standardwahl fir Héichspannungsverdeelung an Iwwerdroungsnetzwierker, typesch dobaussen an Ënnerstatiounen installéiert.

• Effektiv Ofkillung: Den Isoléierueleg absorbéiert effizient Hëtzt aus dem Kär an de Wicklungen an iwwerdréit et op d'Heizkierperfinnen, erlaabt natierlech oder gezwongen Zirkulatioun a méi héich Iwwerlaaschtkapazitéit.
• Superior Isolatioun: Den Ueleg bitt vill besser dielektresch Kraaft wéi Loft, erlaabt fir e méi kompakt Design fir eng bestëmmte Volt Bewäertung a Schutz géint kuerz Circuit.
• Robust Konstruktioun: Entworf fir laangfristeg, zouverlässeg Operatioun (oft 25-30 Joer) an haarden Outdoor Ëmfeld.
• Iwwerlaascht Kapazitéit: Kann temporär Kraaft Iwwerlaascht besser handhaben wéi dréchent Transformatoren wéinst der thermescher Mass an der Ofkillungseigenschaften vum Ueleg.
• Schutz System: Equipéiert mat engem Conservator Tank (Ueleg Expansioun ze erlaben), Otemschwieregkeeten (fir Feuchtigkeit aus der Loft ze absorbéieren), a Schutzrelais (Buchholz relais) fir intern Feeler Detektioun.
• Käschten-effikass: Allgemeng méi ekonomesch fir Héichkraaftapplikatiounen am Verglach mat dréchent Transformatoren.

These oil immersed electrical power distribution transformers handle 50kVA, 100kVA, 150kVA, 200kVA, 250kVA, 300kVA, 400kVA, 450kva, and 500kVA capacities. 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. Dëst miniméiert Energieverloscht. Windings are copper conductors. Copper offers excellent conductivity. 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. Radiators attach to the tank. 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% an 6%. This ensures good short-circuit protection. Kaméidi Niveauen sinn niddereg. Noise stays below standard limits. The tank includes a conservator. The conservator holds extra oil. Uelegvolumen ännert sech mat der Temperatur. A breather protects the oil. The breather keeps moisture out. Silica gel absorbs moisture inside the breather.

Bushings are porcelain or polymer. Bushings verbannen d'Héich- an Nidderspannungskabel. 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.

Uwendungen vun 50kva 100kva 150kva 200kva 250kva 300kva 400kva 450kva 500kva Ueleg ënnerdaach Elektresch 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. Think small factories, Atelieren, 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.

The largest units, 400kVA, 450kVA, an 500 kVA, 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 vun 50kva 100kva 150kva 200kva 250kva 300kva 400kva 450kva 500kva Ueleg ënnerdaach Elektresch Stroumverdeelungstransformator 20kv

Hei sinn 5 common questions about our 50kVA to 500kVA Oil Immersed Distribution Transformers (20kV an):

Wat maachen dës Transformatoren eigentlech?
They safely step down 20kV high voltage electricity to lower voltages suitable for factories, Gebaier, oder Quartieren. They handle power from 50,000 zu 500,000 volt-amp.

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. Dëst hält den Transformator sécher.

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. Follegt lokal elektresch Coden genau. Richteg Buedem ass essentiell fir Sécherheet.

Wat Ënnerhalt néideg ass?
Kontrolléiert den Uelegniveau regelméisseg. Sich no Leckage. Halt de baussenzege propper. Inspect bushings and connections periodically. Test the oil quality every few years. This finds any internal problems early. Follegt den Ënnerhaltplang vum Hiersteller.
