1.1 Semelo sa Morero
Transformer ea motlakase ea koloi ea 8 MVA e ile ea isoa Afrika Boroa ka 2022.
Matla a lekantsoeng a oli e Immersed transformer ke 8000 KVA e nang le pholiso ea ONAF, motlakase oa mantlha ke 33 kV ka ± 10 * 1.5% tapping range (OLTC), motlakase oa bobeli ke 33 kV, ba thehile sehlopha sa vector sa YNa0. Matsoelo a holimo-voltage (HV) ke naleli{7}e hokahaneng le neutral (Y). mona ha ho phallo ea mekhahlelo lipakeng tsa HV le LV windings (e hlalosoang ke "0"). E dumella ho fetoswa ha motlakase karolong e{11}} ya matla a hodimo ntle le ho sitisa mojaro. E lefella ho fapana ha motlakase ho grid kapa lehlakoreng la mojaro. Matla a phahameng a mochini le a motlakase a netefatsa ts'ebetso ea nako e telele{14}ka nako e fokolang. Ka mokhoa oa ho pholisa oa tlhaho (ONAN), transformer e ka sebetsa ka karoloana ea matla a eona a lekantsoeng ka botlalo. Ka mokhoa oa ONAF, ho pholile ha moea ho qobelloang ho etsa hore transformer e fihlele boima bo feletseng ba mojaro (80MVA).

1.3 Litšoantšo
8 MVA sets'oants'o sa setšoantšo sa motlakase oa motlakase le boholo.
02 Tlhahiso
2.1 Ntlha ea bohlokoa
Moko oa motheo o entsoe ka lishiti tse ngata tsa tšepe tsa silicon tse pakiloeng, tse kopantsoeng hammoho le li-fasteners le likhoele ho boloka botsitso ba sebopeho. Sebopeho se sefubelu se fana ka ts'ehetso le ho lokisa, ka likarolo tse matlafalitsoeng tse kopanyang holimo le tlase. Karolo e bohareng ea mantlha e sebelisa likarolo tse ngata tsa thepa e sireletsang ho fokotsa tahlehelo ea hona joale ea eddy. Sebopeho sa kakaretso se tiile, se na le phekolo ea tšireletso ea holim'a metsi, e leng se etsang hore se tšoanelehe bakeng sa libaka tsa indasteri tse hlokang matla a khoheli a tsitsitseng.
2.2 Ho tsubella
Li-winding ke likarolo tsa bohlokoa tsa transformer, li entsoe ka{0}ka koporo ea boleng bo holimo e se nang oksijene, ka theknoloji ea rona e tsoetseng pele le boiphihlelo, mapheo a rona a na le likarolo tse latelang:
1. The windings ba khona ho mamella mabone overvoltage, transient overvoltage, overvoltage nako e telele.
2. Matla a phahameng a thibelang mocheso, e khona ho tsoela pele ho sebetsa ka lilemo tse 20 tlas'a mocheso o hlahisoang ke hona joale.
3. Li-winding li khona ho mamella-circuit current e khutšoane.
4. Matla a phahameng a mechine.
2.3 Tanka
Litanka tsa Transformer tse hlahisoang ke k'hamphani ea rona li na le melemo e mengata:
1. Lisebelisoa tsa boleng bo phahameng: Re sebelisa tšepe ea boleng bo holimo ho etsa hore litanka tsa rona tsa mafura li tšoarelle nako e telele le tse matla.
2. Anti-moetso o thibelang ho bola le ho phatloha-moetso o thibelang ho phatloha{2}}: Litanka tsa rona tsa mafura li hloekisoa ka ho khetheha hore li na le lintho tse thibelang{3}}mehato e metle haholo 'me li entsoe ho latela maemo a amehang ho thibela mollo kapa ho phatloha.
3. Ho sebetsa ka mokhoa o nepahetseng: Re sebelisa lisebelisoa tse tsoetseng pele tsa ho sebetsa le thekenoloji ho etsa bonnete ba ho sebetsa hantle ha tanka ea mafura ho netefatsa ho nepahala ha eona le boleng ba kopano.
4. Sebopeho sa ponahalo: Re ela hloko sebopeho sa ponahalo ea tanka ea mafura, e le hore ponahalo ea eona e be e ntle le e fanang ka seatla se bulehileng, ha e ntse e kopana le litekanyetso tsa indasteri.
5. Bokhoni ba ho itloaetsa: Re ka fana ka tharollo ea tanka e hlophisitsoeng ho latela litlhoko tse khethehileng tsa bareki ho fihlela litlhoko tsa li-transformer tse fapaneng.
2.4 Kopano ea ho Qetela
Kopano ea mantlha le likhoele: Likhoele tsa mantlha le tse matsoelintsoeke, tseo e leng likarolo tsa bohlokoa tsa transfoma ea koloi, li kopantsoe hammoho. Sena se kenyelletsa ho beoa ka hloko le ho boloka li-coil tse pota-potileng bohareng ho theha potoloho ea makenete bakeng sa phetoho ea motlakase.
Insulation le tšireletso: Lisebelisoa tsa insulation li sebelisoa ho sireletsa li-coil tse pota-potileng ho senyeha le ho netefatsa tšireletso ea motlakase le ho tšepahala. Sena se ka 'na sa akarelletsa ho sebelisa litheipi tse sireletsang tšireletso, li-varnish kapa liphahlo tse ling tse sireletsang.
Kgokelo ya ditheminale: Ditheminale tsa dikhoele tse matsoketsane di hoketswe ho dihokedi kapa ditheminale tse loketseng ho transfoma ya koloi, ho netefatsa potoloho e felletseng ya motlakase bakeng sa phetiso ya matla.
03 Teko
1. Teko ea ho hanyetsa mocheso: Lekola khanyetso ea insulation ho netefatsa hore ts'ebetso ea ts'ebetso e kopana le litlhoko.
2. Teko ea ho hanyetsa ho kena-kenana: leka ho hanyetsa ho kheloha ho netefatsa hore ho na le ho koala hantle le ho hokahanya pakeng tsa windings.

4.1 Ho paka
Re khetha lebokose la lehong e le thepa ea ho paka hobane e khona ho jara boima le boholo ba transformer. Joale transformer e sirelelitsoe ka mokhoa o sireletsehileng ka har'a sephutheloana ka marapo kapa li-brackets ho thibela ho sisinyeha nakong ea lipalangoang.
4.2 Ho tsamaisa thepa
Nakong ea ho sebetsana le lipalangoang, kamehla re hlokomela ho sireletsa transformer ho tloha lerōleng, mongobo le tšenyo ea 'mele. Sephutheloana se boetse se tšoailoe ka litaelo tse nepahetseng tsa ho sebetsana le matšoao a tlhokomeliso ho netefatsa hore lipalangoang li bolokehile. Nakong ea lipalangoang, re lula re lekola li-transformer bakeng sa matšoao a tšenyo kapa phalliso, 'me re nka mehato e meng ea ho itšireletsa ha ho hlokahala ho netefatsa polokeho ea thepa. Ha u fihla sebakeng seo u eang ho sona, sephutheloana se tlosoa ka hloko 'me transformer e hlahlojoa hore na ho na le tšenyo efe kapa efe e ka bang teng pele e kenngoa.
05 Sebaka le Kakaretso
Boitokisetso: Lekola motheo oa li-transformer le boemo ba lisebelisoa, etsa licheke tsa ho kenya letsoho, 'me u lokise lisebelisoa tse nepahetseng tsa ho phahamisa le ho li hula.
Hoisting: Phahamisa transformer u sebelisa libaka tse phahamisitsoeng tse boletsoeng, etsa bonnete ba hore e hlophisitsoe hantle ebile e lekantsoe, ebe u e tiisa ka mokhoa o sireletsehileng motheong.
Kopano ea lisebelisoa: Lihlahla tsa Mount, li-radiator tse pholileng, le likarolo tse ling tse thusang, ho netefatsa hore likhokahano tsohle li tiisitsoe le ho tiisoa ho latela litlhaloso.
Ho Enta Oli: Ho tlatsa vacuum oli ka mokhoa o phahameng- oa ho hloekisa oli. Lekola boemo ba oli 'me u netefatse hore litiiso tsohle li tiile ho thibela ho lutla.
Teko: Etsa tlhahlobo, karo-karolelano, ha ho{{0}moroalo, le liteko tse khutšoane- tsa potoloho.
Grounding: Theha mokhoa oa ho beha fatše le ho lekanya khanyetso ea lefats'e ho netefatsa ts'ebetso e bolokehileng le e tšepahalang.
Ho Sebetsa: Habedi{0}lekola mehato yohle ya ho instola, etsa{1}}ka{2}teko ya kgato ya kgato, le ho matlafatsa transformer ka molao hang ha maemo a tshebetso a le ka hara meedi e amohelehang.
