Li-transformer tse sebetsang hantle le tse tšepahalang tsa 6 MVA- tse qoelisoang bakeng sa li-inverter system, tse fanang ka motlakase o bolokehileng, tahlehelo e tlase, le ts'ebetso e tšoarellang libakeng tse kantle tsa Afrika Boroa.
01 Kakaretso
1.1 Tlhaloso ea Morero
Oli ena ea 6MVA{1}}e qoelitsoemotlakase oa motlakasee ile ea isoa Afrika Boroa ka 2024 bakeng sa ho sebelisoa ho li-inverter systems. Transformer ea motlakase ea 6 MVA e na le matla a lekantsoeng a 6000 kVA, motlakase o ka sehloohong oa 33 kV, le motlakase oa bobeli oa 2.2 kV. E latela ka tieo litekanyetso tsa IEC 60076
Leha li-inverters li ka fetola matla a DC hore e be matla a AC, motlakase oa grid hangata o phahame ho feta kamoo inverter e ka mamellang kateng. Ho netefatsa ts'ebetso e bolokehileng ea sistimi, transformer ea rona e theola motlakase o phahameng oa grid (33 kV) ho ea ho 2.2 kV e amohelehang ho inverter. Transformer e boetse e fana ka karohano ea motlakase, khatello ea harmonic, le ts'ireletso ea sistimi, ho netefatsa ts'ebetso e bolokehileng le e tsitsitseng lipakeng tsa inverter le grid.
E ithorisa ka ts'ebetso e phahameng ea ts'ebetso. Ha ho-tahlehelo ea mojaro e tlase joalo ka 6.2 kW, 'me tahlehelo ea thepa e tlase joalo ka 39 kW, e leng ho fokotsa tšebeliso ea matla le litšenyehelo tsa ts'ebetso. 7% impedance e netefatsa hore motlakase o tsitsitse ka nako e khutšoane-ea potoloho, 'me maqhubu a koporo a fana ka conductivity e ntle haholo, e sireletsang motlakase le marang-rang.
Li-transformer tsa motlakase tsa 6 MVA li tlatsitsoe ka oli ea PCB{{1}e sa lefelloeng ea liminerale, e matlafatsang polokeho ea tikoloho. Seseteme ea ho pholisa e sebelisa moea o pholileng oa tlhaho 'me e na le radiator e chesang e chesang-dip galvanized. Sena se netefatsa phediso e hlwahlwa ya mocheso le ho hanyetsa maemo a lehodimo a matla, ho etsa hore e be tse loketseng tikoloho ya kantle ya Afrika Borwa.
Lisebelisoa tse tloaelehileng li kenyelletsa tekanyo ea tekanyo ea oli, valve ea khatello ea khatello, lisebelisoa tsa ho shebella mocheso oa oli le matsoelintsoeke, relay ea Buchholz, le mochine o phefumolohang, ho netefatsa ts'ebetso e sireletsehileng le e tsitsitseng le ho lelefatsa bophelo ba tšebeletso ea thepa. Ka bokhabane ba eona bo phahameng, tahlehelo e tlase, le moralo o matla, 6MVA ena ea oli-e qoelisoang ka matla a ho fetola motlakase ha se khetho e nepahetseng feela bakeng sa gridi e hokahantsoeng{{3}e hokahaneng, empa hape ke karolo ea mantlha e tšepahalang bakeng sa merero e mecha ea matla a matla.

02 Tlhahiso
2.1 Ntlha ea bohlokoa
Re latela ka tieo lits'oants'o tsa meralo, litekanyetso, le mekhoa ea tlhahiso bakeng sa mohato o mong le o mong, ho netefatsa kopano e nepahetseng ea mantlha, khokahano e sireletsehileng ea likarolo tse phelang, le motheo o tšepahalang. Ka taolo ena e thata, li- iron cores tsa rona li fumana tahlehelo e fokolang, lerata le fokotsehileng, matla a ho koala a mangata, le ho sebetsa ka thata ha nako e telele-ea potoloho, ho netefatsa hore{2}}transformer e sebetsa nako e telele.
2.2 Ho tsubella
Ho tsamaisa li-coil ke ts'ebetso ea bohlokoa. Re sebelisa{1}koporo ea boleng bo holimo, e netefatsang tšebetso e ntle haholo le matla a mochini. Nakong ea matsoeli, re boloka mohatsela o tšoanang, sebaka se tsitsitseng, le likarolo tse thata, tse makhethe ho thibela libaka tse chesang haholo le ho se sebetse ha mocheso. Ka mor'a ho tsoelipana, li-coil lia bōptjoa, li sirelelitsoe, 'me li kenngoe, ka tlhahlobo e tiileng ea boleng, ho netefatsa botsitso tlas'a khatello e khutšoanyane-ea potoloho, ea mocheso le motlakase ha e kopana le litlhoko tsa khokahanyo ea Dyn11.

4.2 Ho tsamaisa thepa
Pele o kenya, lekanya boholo le boima ba transformer, 'me u rale tsela e qobang bophahamo, bophara le boima ba lithibelo. Sebelisa-libethe tse tlase kapa literaka tse khethehileng tse nang le bokhoni bo lekaneng.
Lokahanya setsi sa khoheli sa transformer le koloi. Sebelisa litšepe tsa kanale le mekhoa e nepahetseng ea ho tiisa ho tiisa motheo oa teraka, ha ho lumelleha. Sireletsa transformer ka likhoele kapa liketane ka likoti tse khethiloeng tsa lipalangoang, ho qoba likarolo tse senyehang joalo ka li-radiator le lihlahla. Notlela likarolo tse ka hare 'me u tiise menyako eohle.
Boloka lebelo Le ka Tlase kapa le lekana le 60 km/h mme o sekaseke Ka tlase ho kapa ho lekana le likhato tse 15 nakong ea lipalangoang. Qoba ho sisinyeha ka tšohanyetso le ho thothomela ho matla. Abela batho ba felehelitseng ho hlahloba hore na ba tlama hakae le ho emisa lipalangoang maemong a leholimo a mabe.
Ha u phahamisa, boloka li-angles tsa thapo Li le Ka tlase ho kapa li lekana le likhato tse 60. Sebelisa li-spreader bar ha ho hlokahala. Ka linako tsohle phahamisa u otlolohile, 'me bakeng sa li-unit tse se nang li-lugs tse holimo, sebelisa lithupa tse phahamisang tlase.
