Funktsiyoyi da Zabukar Gagar-Gagar na Maimaitaccen Turbinon a Makarantun Shamsi
1.Dukkanin Matattun da Kyakkyawan Sistem
A cikin manyan photovoltaic, na gina matattuwar grounding transformers wanda ke taimaka wajen kawo dukkanin sistem. Daga rike cin kasa na kula, wannan dukkanin yana taimaka wajen ci gaban kyakkyawa a cikin sistem idan an yi abin da ba a matsayin, maimakon hakan ya fi shiga "stabilizer" don duk sistem kula.
2.Kyakkyawan Limitar Karamin Tsirriyar
Don manyan photovoltaic, grounding transformers suna iya limitar karamin tsirriyar da za suka faru. Gaskiya, suna iya kontrolar tsirriyar zuwa 2.6 koyi na tsirriyar da aka sauransu, wanda yana haifar da wahala na lafiya da ke faru saboda karamin tsirriyar.
3.Madabunta Impedance-ko na Karamin Tsirriyar
Idan kana zama wajen zaba grounding transformers, za a duba madabunta impedance-ko na karamin tsirriyar da ma'ana. Zaman lafiya na impedance-ko yana taimaka wajen ci gaban lalacewa da kuma karshen transformer a lokacin da karamin tsirriyar suka faru. Gaskiya, impedance-ko ana kontrolar bayan 4% zuwa 8%.
4.Hanyar Zero-Sequence Current Don Kyakkyawan Sistem
Grounding transformers sun taimaka wajen kawo hanyar zero-sequence current don relay protection devices a cikin manyan photovoltaic, wanda ke taimaka wajen kawo kyakkyawan da take daidai da kuma taimaka wajen bincika da karamin tsirriyar, wanda yana haifar da kyakkyawan da ke faru a cikin sistem.
5.Tsari na Zabe Capacity
Idan kana zama wajen zabe capacity ta grounding transformer, ya kamata a yi tasiri mai sauƙi game da abubuwa kamar girman manyan photovoltaic da kuma adadin karamin tsirriyar. Misali, manyan kadan suna bukatar kawai sararin hundred kVA, amma manyan yawan kasa suna bukatar transformers da ke biyu a thousand kVA.
6.Balancing Three-Phase Current
Grounding transformers sun taimaka wajen balancar currents da ba da matafiya a cikin three-phase systems. Daga rike cin kasa na kula, sun taimaka wajen ci gaban kyakkyawa da ke faru a cikin voltages da ke three-phase, wanda yana haifar da ingantaccen gwamnati na kayan aiki.
7.Madabunta Insulation Performance
Daga rike insulation, grounding transformers suna bukatar samun madabunta insulation da ke daidai da yanayin manyan photovoltaic. Misali, a cikin yanayin da ke da humidity mai yawa, class na insulation ya kamata ita Class F ko daidai.
8.Limitar Ground Fault Current Na Single-Phase
A lokacin da single-phase ground faults suka faru, grounding transformers sun taimaka wajen limitar fault currents zuwa adadin da ke daidai. Gaskiya, fault currents ana kontrolar zuwa several hundred amperes, wanda yana haifar da fault escalation da kuma kisan system-wide disruption.
9.Zabe Hanyar Cooling Method
Zabe hanyar cooling method da ta daidai don grounding transformers yana da muhimmanci. Abubuwan da ake amfani da su sun haɗa oil-immersed self-cooling da dry-type air cooling. Manyan kadan suna da kyau da dry-type air cooling, amma manyan yawan kasa suna da kyau da oil-immersed self-cooling systems.
10.Function na Electrical Isolation
Grounding transformers sun taimaka wajen kawo function na isolation, wanda ke taimaka wajen kawo electrical interference bayan voltage levels da kuma separate systems. Wannan capability yana da muhimmanci a cikin electrical architecture na manyan photovoltaic power stations na zamani.
