750 kVA Pad Mounted Utility Transformer-34.5/0.48 kV|Jamaica 2024

Seseteme sa motlakase sa-mohato oa boraro-ke meralo e atileng haholo lits'ebetsong tsa motlakase, e sebelisang li-cylindrical cores tse tharo tse arohaneng, e 'ngoe le e 'ngoe e tsamaellana le karolo e le 'ngoe ea{2}}mohato oa boraro. Tlhophiso ena e thusa ho ntlafatsa kabo ea matla a khoheli le ho ntlafatsa ts'ebetso ea transformer. Li-winding li kentsoe leotong le leng le le leng 'me hangata li ka hokeloa ka naleli kapa delta configuration ho lumellana le litlhoko tse fapaneng tsa matla.

Nakong ea tlhahiso, mantlha e hahiloe ho tloha maqepheng a tšepe a laminated silicon ho fokotsa tahlehelo ea eddy hajoale le hysteresis, ka hona ho ntlafatsa ts'ebetso ea matla ka kakaretso. Mokhoa oa-moetso oa maoto a mararo ha o fokotse tahlehelo ea mantlha feela empa o boetse o matlafatsa mokhoa oa ho felisa mocheso, o eketsa botsitso ba transformer tlas'a{2}}maemo a phahameng a boima.

Maqhubu a {{0}voltage foil a tlase a sebelisa li-conductive strips tse kholo, tse thusang ho fokotsa ho sekama le ho tiea ha mapheo, ka hona ho fokotsa tahlehelo ea motlakase nakong ea phetiso ea hajoale. Ho feta moo, sebopeho sa foil se nang le lesela se khothaletsa kabo ea hajoale e ts'oanang, e fokotsa ho futhumatsa sebakeng le ho ntlafatsa ts'ebetso e akaretsang.

Maqhubu a phahameng{{0}a matla a motlakase a sebelisa lithapo tse nang le maqeba a manyane a etselitsoeng ho mamella maemo a phahameng a motlakase le ho fana ka matla a holimo a ho koala. Ka sebaka se phahameng-mokhoa oa motlakase o kentsoeng ke foil-ea motlakase o tlase, peakanyo ena e ntlafatsa ho aroloa ha motlakase, e fokotsa tšitiso lipakeng tsa likarolo tsa motlakase, le ho netefatsa ts'ebetso e bolokehileng le e tsitsitseng ea transfoma tlas'a-maemo a phahameng.

Tanka ea transformer e sebetsa e le sebaka sa tšepe se tiisitsoeng se bolokang le ho sireletsa oli e sireletsang. Oli ena e sebetsa e le sehatsela le se pholisang, e thibelang ho senyeha ha motlakase le ho boloka mocheso o bolokehileng oa ho sebetsa.

E entsoe ka matla a matla a mochini, tanka e mamella phapang ea khatello ea kahare le litlamorao tsa kantle. Sebopeho sa eona hangata se kenyelletsa mapheoana a pholileng kapa li-radiator ho ntlafatsa phallo ea mocheso, haholo-holo tlas'a meroalo e phahameng.

Likarolo tsa bohlokoa tsa tanka li kenyelletsa tekanyo ea boemo ba oli bakeng sa ho lekola pono, li-valve tsa ho imolla khatello bakeng sa ts'ireletso e feteletseng, le phefumoloho ho laola phapanyetsano ea moea. Likarolo tsena ka kopanelo li netefatsa ts'ebetso e tšepahalang le e bolokehileng ea transformer.

Nakong ea kopano ea li-transformer, li-core le windings li qala ka ho kopanngoa ho karolo e tiileng pele li kenngoa ka tanka ea oli. Ka mor'a moo, tanka e tlatsoa ka oli e thibelang mocheso bakeng sa ho pholisa le ho kenya letsoho ka katleho, e lateloe ke ho koala ha hermetic ho thibela ho lutla. Ho kentsoe sebaka sa tšepe se sireletsang ho netefatsa bots'epehi ba sebopeho, 'me li-terminal blocks li qetella li hlongoa ho etsa hore likhokahano tsa cable li sireletsehe.

Karolo e meraro-e phahamisitsoeng- transformer e kentsoeng ka har'a moalo o matlafalitsoeng oa tšepe o nang le libaka tsa ho phahamisa le likanale tsa forklift. Likarolo tsa bohlokoa li sirelelitsoe ka likhurumetso{3}} tse monyang, athe bracing e ka hare e fokotsa ho sisinyeha nakong ea leeto. Karolo ena e na le boemo ba leholimo-li-resistant seal le li-desiccant unit ho boloka ho omella ka hare. Lipoleiti tsa boitsebahatso tsa kantle le matšoao a ho sebetsana li fana ka tataiso e hlakileng ea ts'ebetso. Liphutheloana tsohle li kopana le litekanyetso tsa machaba bakeng sa lipalangoang tsa thepa e boima ea motlakase.

Sepalangoang sa-pad pad-mounted pad ke ts'ebetso e khethehileng e shebaneng le ho tsamaisa yuniti e boima, e kentsoeng ho tloha ho moetsi ho ea sebakeng se seng. E hloka tlhahlobo{3}e amohetsoeng pele ho moo ho laola litšitiso, k'haravene e matla bakeng sa ho ts'oara ka mokhoa o sireletsehileng ka li-blocks le mahlaahlela, le ho latela melao e mengata ea boima bo feteletseng. Sepheo ke ho senya{5}ho fihla mahala, ho netefatsa hore transformer e fihla e loketse ho kengoa holim'a letlapa la eona la konkreite.
