1.1 Semelo sa Morero

Ho ts'ehetsa katoloso e ntseng e hola ea lisebelisoa tsa matla a letsatsi 'marakeng oa US, re rometse 2250 kVA -phase three-transformer e kentsoeng ka mokhoa o khethehileng bakeng sa ts'ebeliso-scale photovoltaic (PV) ts'ebeliso. E entsoe ka-mohaho o matla oa maoto a mahlano 'me o shoele-ka pele, lupu-peakanyo ea phepelo, karolo ena e netefatsa polokeho, ts'epahalo, le ho tenyetseha ha sistimi tikolohong ea matla a ka nchafalitsoeng.

Sena2250 kva pad mounted transformere sebetsa ka motlakase o ka sehloohong oa 12.47 GrdY / 7.2 kV le motlakase oa bobeli oa 0.6Y / 0.347 kV, e leng se etsang hore e be se loketseng bakeng sa ho hokahanya le li-inverters tsa letsatsi le marang-rang a kabo ea tlaase. Sehlopha sa li-vector YNyn0 se etsa hore ho be le motheo o sebetsang hantle 'me se nolofalletsa likhokahano tse tlase-mohato oa boraro{7}}mapolasing a letsatsi. Ka aluminium windings, yuniti e fana ka tekanyo pakeng tsa ts'ebetso le ts'ebetso ea litšenyehelo.

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℃) le biodegradability. Moralo oa KNAN (moea oa tlhaho{2}}o pholileng) o fokotsa ho rarahana ha tšebetso le litlhoko tsa tlhokomelo ha o ntse o netefatsa hore mocheso o sebetsa hantle haholo.

E fanoe ka kemiso, transformer ena e kenya letsoho ka ho toba katolosong ea litšebeletso tsa motlakase tsa letsatsi, ho tšehetsa lipakane tse pharaletseng tsa naha tsa decarbonization le grid modernization. E bonts'a bokhoni ba rona ba ho etsa lisebelisuoa tse phahameng- tse sebetsang, tse sebetsang- bakeng sa litlhoko tse ntseng li tsoela pele tsa matla a ka nchafatsoang.
