Muhimmanci na Nau'in:

• Tsarin Kumbin da Kyau: Yana amfani da advanced computational analysis ga electrical, magnetic, mechanical, da thermal behavior don in ba da tsarin da za ta fi dace da kuma zama.

• Zama mai Kyau a Kan Electrical Performance: Ana tabbatar da IEC standards kuma ana ba da solutions masu inganta, kuma partial discharge levels suna da ma'ana mai kyau da limits na IEC 60076-3.

• Karin Zama a Kan Amfani: Multi-physics field analysis yana ba da insulation, amp-turns balance, da cooling da zama, kuma yana ba da kyau a kan overvoltage da short-circuit events kuma yana kasa alamun jiki.

• Zabubbukan Component Selection: Yana ba da user experience mai kyau tare da appearance mai kyau, leak-free construction, da kuma amfani baka-baka ba da sabbin disassembly.

Parametoci Na Zamani

Daga cikin haka, wasu autotransformers suna da voltage levels da ba su duka standard kamar 121kV, 132kV, 138kV, 200kV, 225kV, 230kV, 245kV, 275kV, 330kV, 345kV, 400kV da 756kV, A nan muna ba da services masu inganta.

Tambaya: Tafin karkashin halayyar da na duka tushen da kuma ayyukar da suka sa shi za su iya gina daidai saboda ma'aikatar mutanen mawaki.

Matsayin Al'adu Daga Baka

(1) Tsarin yamma:  ≤1000m;

(2) Tsari na yamma: Yammacin tsari: +40℃;Yammacin tsari na watan: +30℃;Yammacin tsari na shekarar: +20℃;Kadan tsari: -25℃.

(3) Tashar noma: hanyoyin kamar sinusoide, uku masu inganci kamar

(4) Ingantaccen bayanin: tushen karamin kofin ko karamin kofin, bane da lafiya mai zama.Note: Tafiya da ake amfani da ita a matsayin da ba duka baka ba ya kamata a bayyana lokacin da ake faɗa.

Bayanin Karkashin da Ayyuka:

Gurbin:

• Amfani da abubuwan da suka fi sani, babban tufafi, karamin kofin, da kuma abubuwan da suka fi sani da karamin kofin, da kuma abubuwan da suka fi sani da karamin kofin da karamin kofin.

• An yanke a kan layin GEORG na Germany.

• Duk mitred joint, step lapping da polyester tape binding structure take samun tafiya da hasashe da kuma tafiya da hasashe da karamin kofin.

• An yi magance vibration isolation pads bayan gurbin da kofin don kusan hasashe da ke cika zuwa kofin.

Ayyukan:

• An ayyuka da oxygen free copper ta da hasashe.

• An yanke da horizontal winding machines da kuma large CNC vertical winding machines bayan radian da kuma axial directions.

• Amfani da reasonable transposition bayan paralleling wires, magnetic shielding a yi amfani da shi idan an bukata don kusan hasashe da ke cika zuwa tafiya.

• Na yi amfani da reasonable design of insulation structure don kusan jirgin samun overvoltage.

• An yanke da ampere turns distribution of the winding, increasing the radial support and axial compression of the winding, using the pre-densification of spacers, constant pressure drying, to resist the impulse current.

Kofin:

• Bell type or cover bolted type tank.

• Carbon dioxide shielded welding process.

• High-quality gaskets and the limit groove.

• Strict leak detection test procedures.

Wasu:

• Cold-weld connection technology leads to improve the cleanliness of active part.

• The vacuum disassembly and the vacuum filling technology measures reduce the partial discharge level effectively and enhance the transformer operating reliability.

• The structure of "Six Direction Positioning" between the active part and the tank assures that the transformer has a strong ability of anti-transportation impact or anti-earthquake.

• Surface treatment and coating, fine processing to tank surface, 7 steps such as acid-washing and phosphating, etc. special anti-fouling paint, ensuring not falling off or rusting away.
