1.1 Tlhaloso ea Morero

1.5 MVA (1500 kVA)tse tharo-pase ea mekhahlelo-e kentsoeng ka transformere fana ka ts'epahalo, e sebetsang-matla a boemo bo botle sebakeng se kopaneng, se thibaneng{1} E hahiloe ho kopana le IEEE Std C57.12.34-2022, DOE 2016, le litekanyetso tse thathamisitsoeng tsa UL. E fana ka tharollo e bolokehileng le e sebetsang hantle bakeng sa litsamaiso tse mahareng tsa- tsa motlakase 'me e tla le tiisetso ea lilemo tse 3 bakeng sa ts'epahalo ea nako e telele.

Transformer e na le lupu-feela ebile e shoele{1}moetso o ka pele. E fetola motlakase ho tloha ho 12.47 kV ka lehlakoreng le ka sehloohong ho ea ho 4.16 kV ka lehlakoreng la bobeli le sehlopha sa li-vector Dyn1. Setupo sena se sebetsa hantle bakeng sa mefuta e mengata ea marang-rang. E na le maemo a mahlano a ho theoha-ea lipompo tsa potoloho (14.4 kV, 13.8 kV, 13.2 kV, 12.47 kV, 12.0 kV) ho lokisa motlakase kamoo ho hlokahalang sebakeng. E sebelisa pholiso ea ONAN le ho kenya oli ea liminerale. Ho phahama ha mocheso ke likhato tse 65. Likarolo tsena li boloka transformer e tsitsitse mme e lelefatsa bophelo ba eona ba ts'ebeletso.

Maqhubu a eona a aluminium a fana ka ho leka-lekana ha nako e telele le ho sebetsa hantle ha litšenyehelo, ha impedance ea 5.75% e tšehetsa tsamaiso ea liphoso e tšepahalang. E lekoa bakeng sa tahlehelo ea DOE 2016-ha ho{4}tahlehelo ea mojaro ea 1,545 W le tahlehelo ea thepa ea 10,540 W{9}moetso o kopana le lipehelo tsa tšebetso-e sebetsang hantle le ho fokotsa litšenyehelo tsa ts'ebetso. Lisebelisoa tse tloaelehileng li kenyelletsa fuse ea bayonet e nang le lihokelo tsa ho itšehla thajana le likarolo tse tharo-, tse peli-li-position load break switch.

Likarolo tsena li etsa hore tšireletso e be bonolo le hore ts'ebetso e bolokehe.

Transformer e kopane, e ka tšeptjoa ebile e bonolo ho e hlokomela. Ke khetho e ntle bakeng sa lits'ebetso tsa phepelo ea lisebelisoa, libaka tsa matla tse nchafalitsoeng, lits'ebeletso tsa indasteri, le marang-rang a motlakase oa meaho Amerika (ho tsamaisoa ha 2025).

02 Tlhahiso

2.1 Ntlha ea bohlokoa

The 1500 KVA electrical transformer box core e na le-maoto a mararo, mohato{2}}moetso o entsoeng ka lap mitered. E entsoe ka tšepe ea lijo-thollo-e tšekaletseng, e batang{5}}e kolobisitsoeng ka silicon. Lamination e 'ngoe le e' ngoe e khaotsoe ka mokhoa o nepahetseng 'me ha e na li-burrs. Sena se thusa ho theola tahlehelo ea mantlha le ho fokotsa lerata. Li-lamination li phuthetsoe 'me li tlameletsoe ka thata ho qoba likheo tsa moea. Sena se ntlafatsa ts'ebetso ea makenete mme se boloka transformer e sebetsa hantle ebile e tšepahala.

2.2 Ho tsubella

Transformer e na le terata-e phahameng maqeba a phahameng-likhoele tsa motlakase oa mantlha le lakane-likhoele tsa maqeba tsa bobeli. Moralo ona o fokotsa khatello ea maikutlo e bakoang ke li-circuits tse khutšoane mme o lumella kabo e leka-lekaneng ea matla a khoheli ho pholletsa le likhokahano tsa pompo. Likhoele li entsoe ka metjhini e tsoelipanang hantle{{5}e nepahetseng e netefatsang tsitsipano e sa fetoheng le ho beoa ha conductor ka nepo, ho fa transformer e matla e khutsufalitsoeng{6}}e thibang potoloho le ho sebetsa hantle haholo.

2.3 Tanka

Tanka ea transformer e entsoe ka tšepe e bonolo. E matla 'me ho bonolo ho e tšoara, ho e kenya le ho e hlokomela. Tanka e na le sekoahelo se tiisitsoeng sa bolt ho sireletsa mokelikeli o sireletsang le likarolo tse ka hare. Tšepe e nepahetse-e sehiloe, ea chesa-ea phuthoa, ea tšeloa, 'me e tlotsoe ka oli. The welding e etsa bonnete ba hore tanka e tšoarella ebile e ka tšeptjoa.

2.4 Kopano ea ho Qetela

Thepad{{0}sefetoleli se ka holimocore le coil assembly e tlamiloe ka litšepe tse boima ho thibela likhoele tse khutlonnetsepa hore li se kobehe ka nako e khutšoane-ea potoloho. Lipoleiti li tlanngoe ka thata ka li-presses ebe lia chesetsoa kapa li bouheloa ho etsa sebopeho se tiileng. Kopano e kopana kapa e feta ditekanyetso tsa ANSI le IEEE tse khutšoane- tsa potoloho. Moralo o thata o etsa hore litšitiso li be nyane, joalo ka selika-likoe-likhoele tsa maqeba.
