Transformadores elétricos de baixa perda, transformador de distribuição imerso em óleo trifásico 20kva-5MVA

Overview of Electric Transformers Low Loss Three Phase Oil Immersed Distribution Power Transformer 20kva-5MVA

Um transformador imerso em óleo é um tipo de transformador elétrico onde o núcleo e os enrolamentos estão submersos em um óleo isolante. Este óleo desempenha duas funções principais: atua como um isolante altamente eficaz entre peças condutoras e como refrigerante para dissipar o calor gerado durante a operação. Esses transformadores são robustos, confiável, e altamente eficiente, tornando-os a escolha padrão para redes de distribuição e transmissão de energia de alta tensão, normalmente instalado ao ar livre em subestações.

Features of Electric Transformers Low Loss Three Phase Oil Immersed Distribution Power Transformer 20kva-5MVA

• Resfriamento Eficaz: O óleo isolante absorve eficientemente o calor do núcleo e dos enrolamentos e o transfere para as aletas do radiador, permitindo circulação natural ou forçada e maior capacidade de sobrecarga.
• Isolamento Superior: O óleo fornece rigidez dielétrica muito melhor que o ar, permitindo um design mais compacto para uma determinada tensão nominal e protegendo contra curtos-circuitos.
• Construção Robusta: Projetado para longo prazo, operação confiável (muitas vezes 25-30 anos) em ambientes externos agressivos.
• Capacidade de sobrecarga: Pode lidar melhor com sobrecargas de energia temporárias do que transformadores do tipo seco devido à massa térmica e às propriedades de resfriamento do óleo.
• Sistema de Proteção: Equipado com tanque conservador (para permitir a expansão do óleo), respiradouro (para absorver a umidade do ar), e relés de proteção (Revezamento Buchholz) para detecção de falhas internas.
• Econômico: Geralmente mais econômico para aplicações de alta potência em comparação com transformadores do tipo seco.

5 FAQs of Electric Transformers Low Loss Three Phase Oil Immersed Distribution Power Transformer 20kva-5MVA

Here are five common questions about our low loss three phase oil immersed distribution power transformers (20kva-5MVA):

O que torna este transformador “baixa perda”?
Our design significantly cuts down wasted energy. We use top quality grain-oriented silicon steel for the core. This reduces no-load loss. No-load loss happens when the transformer is plugged in but not powering equipment. We also optimize the windings. This lowers load loss. Load loss occurs during actual power delivery. Lower losses mean lower electricity bills over the transformer’s life.

What capacity range do these transformers cover?
We offer these transformers from 20 quilovolt-amperes (kVA) até 5 megavolt-amperes (AMIU). This range suits many distribution needs. Common uses include powering factories, edifícios comerciais, housing complexes, and renewable energy connection points. Tell us your specific voltage and power requirements. We find the right size unit for you.

Como este transformador é instalado?
A instalação precisa de um planejamento cuidadoso. The transformer arrives filled with insulating oil. It is heavy. Ensure your site has a strong, fundação de nível. Proper lifting equipment is essential. Connect the high voltage and low voltage terminals correctly. Follow all safety codes. Qualified electrical personnel must handle installation and commissioning. We provide detailed installation manuals.

Que manutenção é necessária?
Regular checks keep the transformer reliable. Visually inspect the tank for leaks. Monitor the oil level using the gauge. Check the oil temperature. Sample the insulating oil periodically. Lab analysis finds moisture or breakdown products. Clean the radiators to prevent overheating. Keep the area around the transformer clear. Follow the maintenance schedule in the manual. Major internal work needs specialists.

Esses transformadores são seguros?
A segurança é crítica. O robusto tanque de aço protege o núcleo e os enrolamentos. The insulating oil cools the unit. Também evita arco elétrico. Units include a conservator tank. This allows oil to expand and contract safely. A breather stops moisture entering the oil. Pressure relief devices guard against internal faults. Buchholz relays detect gas from internal problems. They trigger an alarm or shutdown. Always follow electrical safety procedures.
