High Performance 8 MVA 11 KV 0.4 KV Oil Immersed Transformer for Urban Distribution

Overview of High Performance 8 MVA 11 KV 0.4 KV Oil Immersed Transformer for Urban Distribution

Trafo terendam oli adalah jenis trafo listrik yang inti dan belitannya terendam dalam minyak isolasi.. Minyak ini memiliki dua fungsi utama: ia bertindak sebagai isolator yang sangat efektif antara bagian konduktif dan sebagai pendingin untuk menghilangkan panas yang dihasilkan selama pengoperasian. Transformator ini kuat, dapat diandalkan, dan sangat efisien, menjadikannya pilihan standar untuk jaringan distribusi dan transmisi tenaga listrik tegangan tinggi, biasanya dipasang di luar ruangan di gardu induk.

Features of High Performance 8 MVA 11 KV 0.4 KV Oil Immersed Transformer for Urban Distribution

• Pendinginan yang Efektif: Oli isolasi secara efisien menyerap panas dari inti dan belitan serta memindahkannya ke sirip radiator, memungkinkan sirkulasi alami atau paksa dan kapasitas kelebihan beban yang lebih tinggi.
• Isolasi Unggul: Minyak memberikan kekuatan dielektrik yang jauh lebih baik dibandingkan udara, memungkinkan desain yang lebih kompak untuk peringkat tegangan tertentu dan melindungi terhadap korsleting.
• Konstruksi Kuat: Dirancang untuk jangka panjang, operasi yang andal (sering 25-30 bertahun-tahun) di lingkungan luar ruangan yang keras.
• Kapasitas Kelebihan Beban: Dapat menangani kelebihan daya sementara dengan lebih baik daripada transformator tipe kering karena massa termal dan sifat pendinginan oli.
• Sistem Proteksi: Dilengkapi dengan tangki konservator (untuk memungkinkan ekspansi minyak), istirahat (untuk menyerap kelembapan dari udara), dan relay pelindung (Relai Buchholz) untuk deteksi kesalahan internal.
• Hemat Biaya: Umumnya lebih ekonomis untuk aplikasi daya tinggi dibandingkan trafo tipe kering.

The system makes use of ONAN air conditioning. This suggests Oil Natural Air Natural. Warmth increases naturally via the oil. The container’s surface area radiates warmth into the surrounding air. Outside radiators improve cooling down capability if required. This layout is basic and trustworthy.

The transformer has off-circuit tap changers. These readjust the result voltage somewhat. This compensates for differing grid problems. Level and temperature assesses monitor the oil quickly. Grounding terminals are robust and plainly significant.

This transformer masters efficiency. It meets stringent energy loss criteria. Noise degrees are reduced. This is vital for installments near structures or homes. Its compact impact matches space-limited urban substations. The durable building and construction makes sure a long service life. It deals with heavy loads reliably day and night.

Strenuous manufacturing facility testing assurances efficiency. Tests include resistance checks, proportion confirmation, and insulation resistance. Polarity and vector team tests validate proper phase connections. Applied and induced voltage tests show dielectric strength. Full tons tests show temperature rise limits. The system fulfills all IEC 60076 standards.

Applications of High Performance 8 MVA 11 KV 0.4 KV Oil Immersed Transformer for Urban Distribution

This transformer takes care of power in hectic city areas. It steps down 11,000 volts to safer 400 volts. This voltage is appropriate for shops, offices, and homes close by. Its 8 MVA dimension fits well for medium-density urban zones needing dependable power.

Cities have special power difficulties. Space is tight for tools. Power demand is high and maintains changing. This transformer is developed for these conditions. Its oil cooling down manages warmth effectively even during peak use times. This prevents overheating problems common in congested locations.

Reliability is critical in cities. Power failures trigger huge disruptions. This transformer makes use of proven oil-immersion technology. It safeguards interior components effectively. This design guarantees lengthy life and stable procedure. It handles everyday tons swings without trouble. This suggests less disruptions for consumers.

Safety and security is a major focus. The durable storage tank consists of the oil firmly. Special defense systems monitor stress and temperature level regularly. These systems activate alarm systems or closures if anything uncommon occurs. This avoids mishaps and secures the wider network.

Installment in cities is much easier with this design. Its physical impact is fairly portable. This matters where substation room is expensive and restricted. Maintenance is likewise straightforward. Technicians can easily access key parts for checks and solution. This maintains the transformer running efficiently for years.

The transformer supplies power effectively. Lower power losses suggest reduced operating expense. This profits the power company and eventually the consumer. It gives the solid, consistent electricity modern metropolitan life demands.
