50kva 100kva 150kva 200kva 250kva 300kva 400kva 450kva 500kva Minyak Rendam Pengagihan Kuasa Elektrik Transformer 20kv

Overview of 50kva 100kva 150kva 200kva 250kva 300kva 400kva 450kva 500kva Oil Immersed Electrical Power Distribution Transformer 20kv

Transformer terendam minyak ialah sejenis pengubah elektrik di mana teras dan belitannya terendam dalam minyak penebat. Minyak ini mempunyai dua fungsi utama: ia bertindak sebagai penebat yang sangat berkesan antara bahagian konduktif dan sebagai penyejuk untuk menghilangkan haba yang dihasilkan semasa operasi. Transformer ini adalah teguh, boleh dipercayai, dan sangat cekap, menjadikannya pilihan standard untuk rangkaian pengagihan dan penghantaran kuasa voltan tinggi, biasanya dipasang di luar di pencawang.

Features of 50kva 100kva 150kva 200kva 250kva 300kva 400kva 450kva 500kva Oil Immersed Electrical Power Distribution Transformer 20kv

• Penyejukan Berkesan: Minyak penebat dengan cekap menyerap haba dari teras dan belitan dan memindahkannya ke sirip radiator, membenarkan peredaran semula jadi atau terpaksa dan kapasiti beban lampau yang lebih tinggi.
• Penebat Unggul: Minyak memberikan kekuatan dielektrik yang jauh lebih baik daripada udara, membenarkan reka bentuk yang lebih padat untuk penarafan voltan yang diberikan dan melindungi daripada litar pintas.
• Pembinaan Teguh: Direka untuk jangka panjang, operasi yang boleh dipercayai (selalunya 25-30 tahun) dalam persekitaran luar yang keras.
• Kapasiti Lebihan: Boleh mengendalikan lebihan kuasa sementara lebih baik daripada transformer jenis kering kerana jisim haba dan sifat penyejukan minyak.
• Sistem Perlindungan: Dilengkapi dengan tangki konservator (untuk membolehkan pengembangan minyak), bernafas (untuk menyerap lembapan dari udara), dan geganti pelindung (Relay Buchholz) untuk pengesanan kerosakan dalaman.
• Kos-Efektif: Secara amnya lebih menjimatkan untuk aplikasi berkuasa tinggi berbanding transformer jenis kering.

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.

Teras menggunakan keluli silikon berorientasikan bijian gred tinggi. Ini meminimumkan kehilangan tenaga. Windings are copper conductors. Tembaga menawarkan kekonduksian yang sangat baik. 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% dan 6%. This ensures good short-circuit protection. Tahap bunyi adalah rendah. Noise stays below standard limits. The tank includes a conservator. The conservator holds extra oil. Oil volume changes with temperature. A breather protects the oil. The breather keeps moisture out. Silica gel absorbs moisture inside the breather.

Bushings are porcelain or polymer. Bushings connect the high and low voltage cables. 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.

Applications of 50kva 100kva 150kva 200kva 250kva 300kva 400kva 450kva 500kva Oil Immersed Electrical 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, bengkel, 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.

Unit terbesar, 400kVA, 450kVA, dan 500kVA, 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 of 50kva 100kva 150kva 200kva 250kva 300kva 400kva 450kva 500kva Oil Immersed Electrical Power Distribution Transformer 20kv

Berikut adalah 5 common questions about our 50kVA to 500kVA Oil Immersed Distribution Transformers (20kV):

Apakah sebenarnya yang dilakukan oleh transformer ini?
They safely step down 20kV high voltage electricity to lower voltages suitable for factories, bangunan, or neighborhoods. They handle power from 50,000 kepada 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. Ia melindungi bahagian dalaman. It also cools the transformer. The transformer gets hot during operation. The oil carries this heat away to the tank walls. This keeps the transformer running safely.

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. Ikut kod elektrik tempatan dengan tepat. Pembumian yang betul adalah penting untuk keselamatan.

Apakah penyelenggaraan yang diperlukan?
Periksa paras minyak dengan kerap. Cari kebocoran. Pastikan luaran bersih. Inspect bushings and connections periodically. Test the oil quality every few years. This finds any internal problems early. Ikut jadual penyelenggaraan pengeluar.
