400 Kva 500kva 630 Kva 1500 Kva 3 Phase Oil Immersed Distribution Transformer

Overview of 400 Kva 500kva 630 Kva 1500 Kva 3 Phase Oil Immersed Distribution Transformer

Un trasformatore immerso in olio è un tipo di trasformatore elettrico in cui il nucleo e gli avvolgimenti sono immersi in un olio isolante. Questo olio svolge due funzioni principali: agisce come un isolante altamente efficace tra le parti conduttrici e come refrigerante per dissipare il calore generato durante il funzionamento. Questi trasformatori sono robusti, affidabile, e altamente efficiente, rendendoli la scelta standard per le reti di distribuzione e trasmissione di energia ad alta tensione, tipicamente installato all'aperto nelle sottostazioni.

Features of 400 Kva 500kva 630 Kva 1500 Kva 3 Phase Oil Immersed Distribution Transformer

• Raffreddamento efficace: L'olio isolante assorbe efficacemente il calore dal nucleo e dagli avvolgimenti e lo trasferisce alle alette del radiatore, consentendo la circolazione naturale o forzata e una maggiore capacità di sovraccarico.
• Isolamento superiore: L'olio fornisce una rigidità dielettrica molto migliore rispetto all'aria, consentendo un design più compatto per una determinata tensione nominale e proteggendo dai cortocircuiti.
• Costruzione robusta: Progettato per il lungo termine, funzionamento affidabile (Spesso 25-30 anni) in ambienti esterni difficili.
• Capacità di sovraccarico: Può gestire sovraccarichi di potenza temporanei meglio dei trasformatori di tipo a secco grazie alla massa termica e alle proprietà di raffreddamento dell'olio.
• Sistema di protezione: Dotato di serbatoio conservatore (per consentire l'espansione dell'olio), respiro (per assorbire l'umidità dall'aria), e relè di protezione (Staffetta Buchholz) per il rilevamento dei guasti interni.
• Conveniente: Generalmente più economico per applicazioni ad alta potenza rispetto ai trasformatori a secco.

Applications of 400 Kva 500kva 630 Kva 1500 Kva 3 Phase Oil Immersed Distribution Transformer

These transformers handle big power jobs. They take high voltage electricity and make it lower voltage. This is for factories, buildings, places needing lots of power. The transformer core sits inside a strong steel tank. The tank is filled with special insulating oil. This oil cools the transformer. The oil carries heat away. This keeps things working right. It stops the transformer from getting too hot. These transformers are built tough. They handle daily use well. They last a long time. They work in different weather. Hot days, cold days, they keep going. They are reliable equipment.

Sizes include 400 kVA, 500 kVA, 630 kVA, up to 1500 kVA. These sizes suit many industrial needs. Use them in manufacturing plants. They power heavy machinery. Use them in large commercial buildings. They run lighting, Sistemi HVAC, elevators. Use them for water treatment plants. They run pumps and controls. Use them for mining operations. They power drills and processing equipment. Use them with renewable energy sites. They connect solar farms or wind farms to the grid. They step up voltage for efficient transmission. They step down voltage for local use.

The oil insulation is key. It handles high voltages safely. It makes the transformer more efficient. Less energy is lost as heat. The steel tank protects the inside parts. It keeps dirt and water out. The design allows for easy maintenance. Technicians can check oil levels. They can test oil quality. They can inspect connections. This helps prevent problems. It keeps the transformer running smoothly for years. These units meet strict safety standards. They are built for stable operation. They provide consistent voltage output. This protects sensitive equipment downstream. They are a practical solution for serious power distribution.
