1.1 Tlhaloso ea Morero

Sena750kVA phasewete e kentsoeng phasejeng ea mekhahlelo e meraroe tlisitsoe Amerika ka 2024. E entsoe tlas'a IEEE Std C57.12.34-2022 'me e kopana le maemo a sebetsang hantle a matla a DOE 2016. Ho sebetsa hantle ke 99.4%. E na le loop feed le moralo oa pele-pele bakeng sa tšebeliso e sireletsehileng le e bonolo libakeng tsa indasteri le tsa khoebo. Matla a lekantsoeng ke 750kVA, a nang le motlakase oa mantlha oa 13.2 kV le motlakase oa bobeli oa 0.48 kV. Transformer e thathamisitsoe ke UL, e kopanang le litekanyetso tsa ts'ireletso tsa US.

Impedans ke 5.75%. Ha ho-tahlehelo ea mojaro ke 1.05kW. Tahlehelo ea mojaro ke 5.4kW. Litahlehelo tsena tse tlase li boloka matla le ho ntlafatsa ts'ebetso. Topi ea ho fetola ha se-mofuta oa ho kenya (NLTC). E na le sebaka sa ± 2 × 2.5% ho fetola motlakase.

Maqhubu a aluminium a bobebe, a matla, 'me a loketse ho fetisa mocheso. E boloka transformer e pholile ebile e tsitsitse tlas'a mojaro. Sistimi ea ho futhumatsa ea ONAN e sebelisa oli ea tlhaho le phallo ea moea ho laola mocheso.

Tanka e entsoe ka tšepe e bonolo 'me e tlositsoe ka pente e thibelang{0}} ho bola. E matla 'me e fosahetse-ka bopaki. The dead{4}sebopeho se ka pele se boloka basebelisi ba sireletsehile ka ho koahela likarolo tse phelang. Sistimi ea phepelo ea loop e lumella ts'ebetso e tsoelang pele ha lehlakore le leng le le tlas'a tlhokomelo, e leng ho ntlafatsang ho tšepahala ho marang-rang a matla.
Transformer ena e sebelisoa sebakeng sa henoLisebelisoa tsa indasterilelitsamaiso tsa kabo ea lisebelisoa. E boetse e loketse bakeng salitsi tsa khoebo, lisebelisoa tsa data, le liteishene tsa ka ntle. E fana ka matla a tsitsitseng le a sebetsang moo ho ts'eptjoang le polokeho ho bohlokoa.

02 Tlhahiso

2.1 Ntlha ea bohlokoa

2.2 Ho tsubella

2.3 Tanka

Tanka ea oli e entsoe ka tšepe e bonolo. E na le moralo o tiisitsoeng o nang le sekoahelo se bolted. Sebopeho sena se fana ka tšehetso e matla le ho thibela ho lutla ha oli. Mokhoa oa ho pholisa oa ONAN o sebelisa phallo ea oli ea tlhaho ho tlosa mocheso. E boloka transformer e pholile le ha mojaro o le holimo. Bokahohle bo hloekisitsoe ka lilakane tse thibelang{5}ho bola, ho lelefatsa bophelo ba ts'ebeletso maemong a thata a kantle.

 

2.4 Kopano ea ho Qetela

Li-core le li-coil lia hloekisoa, lia hlahlojoa, 'me li tsamaellana hantle, li tšehelitsoe ka mapheo a aluminium le ho koalloa bakeng sa botsitso. Nakong ea tanka, karolo e sebetsang e theoleloa ka har'a tanka e hloekileng, e behiloe hantle, 'me e sirelelitsoe ka litšehetso tsa insulation.

Lisebelisoa tse kang- le li-voltage tse phahameng-li-voltage bushings, li-radiator, valve ea ho fokotsa khatello ea maikutlo, li-lift lugs le ho tima{2}}circuit tap changer li kentsoe le ho koaloa. Likarolo tse ling li kenyelletsa fuse ea bayonet e nang le li-CLF, switch ea 2-position LBOR, gauge ea boemo ba metsi, gauge ea vacuum gauge, thermometer ea mofuta oa dial, le drain le valve ea sampole bakeng sa ts'ebetso e bolokehileng le tlhahlobo e bonolo.

Thepa e na le vacuum-e tlatsitsoeng ka oli ea minerale, e netefatsang tiiso e nepahetseng le boemo ba oli. Liteko tsa motlakase tse joalo ka ho hanyetsa, karo-karolelano, kamano ea mohato, tahlehelo, ho mamella motlakase, ho kenya letsoho, ho lutla le liteko tsa dielectric tsa oli li netefatsa ts'ebetso e tšepahalang le ho latela maemo a moralo.

Qetellong, bokantle boa hloekisoa, bo koaheloa le ho hlahlojoa. Lintlha tsa Nameplate, matšoao a terminal, le litšoantšo tsa wiring li netefatsoa ka nepo pele li paka le ho tlisoa.

05 Sebaka le Kakaretso

Scotech 750kVA pad mounted transformer loop feed e ile ea isoa Amerika ka 2024. Loop feed le moralo oa eona o shoeleng-o fana ka polokeho, tlhokomelo e bonolo, le ts'ebetso e tsoelang pele.

Transformer e sebelisa-maoto a mararo a tšepe ea silicon e nang le tahlehelo e tlase le lerata le tlase. Maqhubu a aluminium a fana ka ts'ebetso e matla, phetisetso e ntle ea mocheso, le bophelo bo bolelele ba ts'ebeletso. Lisebelisoa tse tloaelehileng le tse ling li kenyelletsa li-bushings, valve ea ho fokotsa khatello, mochine oa ho fetola pompo, fuse ea bayonet e nang le CLFs, 2-position LBOR switch, mokelikeli oa tekanyo ea metsi, mochine oa khatello ea khatello, thermometer ea mofuta oa dial, le drain le valve ea sampole.

Transformer ha e na vacuum-e tletse oli ea liminerale 'me e feta liteko tsa kamehla tsa ho hanyetsa, karo-karolelano, kamano ea mekhahlelo, tahlehelo, ho mamella ha motlakase, ho kenya letsoho, ho lutla, le ts'ebetso ea dielectric tsa oli. Li-transformer tsa Scotech li fana ka matla a ts'eptjoang,{2}}e sebetsang hantle, le a theko e tlaase{3}} bakeng sa marang-rang a sejoale-joale a mekhahlelo e 3.
