2250 kVA pad mounted transformer{1}} arụpụtara maka ugbo anyanwụ, nke e wuru maka nchekwa, arụmọrụ, yana ọdịnihu ike ndụ ndụ.
01 Izugbe
1.1 Ihe ndabere oru ngo
Iji kwado mgbasawanye nke sistemu ike anyanwụ n'ahịa US, anyị wetara 2250 kVA three-phase pad- mounted transformer nke ahaziri maka ịba uru-scale photovoltaic (PV) ngwa. Ejiri usoro isi isi ụkwụ ise siri ike- na nwụrụ anwụ{8}}ihu, loop{9}} nhazi ndepụta, nkeji a na-eme ka nchekwa, ntụkwasị obi, na mgbanwe sistemu na gburugburu ike mmeghari ohuru.
Nke a2250 kva mpe mpe akwa n'elu transformerna-arụ ọrụ na voltaji mbụ nke 12.47 GrdY / 7.2 kV na voltaji nke abụọ nke 0.6Y / 0.347 kV, na-eme ka ọ dị mma maka ịmekọrịta na ndị na-atụgharị anyanwụ na netwọk nkesa ala. Otu vector YNyn0 na-eme ka ala dị mma ma na-eme ka njikọ dị ala{6}}voltaji atọ- na-arụ ọrụ n'ugbo anyanwụ. Na aluminom windings, unit na-enye nguzozi n'etiti arụmọrụ na ọnụ ahịa arụmọrụ.
Built with FR3 natural ester fluid, the transformer achieves a high level of environmental sustainability and fire safety, thanks to its high flash point (>300 degrees) na biodegradability. Nhazi nke KNAN (ikuku eke {{2} jụrụ oyi) na-ebelata ịdị mgbagwoju anya na mkpa nrụzi ma na-ahụ na arụmọrụ ọkụ dị mma.
A na-ebunye ya na nhazi oge, transformer na-enye aka ozugbo na mgbasawanye akụrụngwa nke anyanwụ nke onye ahịa, na-akwado ebumnuche mba sara mbara nke decarbonization na imeziwanye grid. Ọ na-egosipụta ike anyị nwere ike ịrụ ọrụ dị elu{1}, arụmọrụ, ngwa ọrụ{2}ngwaọrụ ọkwa maka mkpa mgbanwe nke ngalaba ume ọhụrụ.
