1.1 Tlhaloso ea Morero

Ka 2025, moreki oa Amerika o ile a etsa odara ea2660 kVA phasewete tse tharo mounted transformer, e etselitsoeng ho kengoa ka har'a marang-rang a medium voltage distribution transformer naheng ea United States, moo botšepehi, polokeho, le ts'ebetso ea nako e telele-e neng e le bohlokoa bakeng sa meralo ea motlakase ea projeke. Transformer e sebetsa joalo ka lebokoso la ka ntle la transformer, e kopanyang tanka ea transfoma, lisebelisoa tsa ho chencha, lisebelisoa tsa ts'ireletso, le likarolo tsa khokahanyo ea motlakase ka har'a compact pad-e kampetsoeng e loketseng marang-rang a phano ea lisebelisoa le tikoloho ea indasteri. Ho feta moo, e le karolo ea odara e tšoanang, moreki o ile a reka e nyane150 kVA pad mounted transformerho fana ka meroalo e thusang ka har'a sistimi ea motlakase ea morero.

Unit e reitiloe ho 2660 kVA, e nang le motlakase oa mantlha oa 22.8 kV le motlakase oa bobeli oa 0.8 kV, 'me e sebelisa sehlopha sa li-vector tsa YNd1, se tšehetsang phetoho e tsitsitseng ea mekhahlelo e meraro{4}; Litšobotsi tse nepahetseng tsa ho falla le ho theola fatše lia hlokomeloa, joalo ka ha ho hlokahala bakeng sa litsamaiso tsa phepelo ea motlakase o mahareng. Tiisetso ena e theola utility medium{6}}motlakase oa motlakase ka katleho, ha e ntse e fana ka motlakase o sa fetoheng ho matla a motlakase a theohang -a tšepahala, a tsitsitse, 'me a loketse ho kopanngoa ha marang-rang.

E entsoe le ho etsoa ho latela IEEE Std C57.12.34-2022, transformer e lumellana le litekanyetso tsa Amerika Leboea bakeng sa lisebelisoa tsa transfoma tse kentsoeng ka pad, ho netefatsa ts'ebetso e sireletsehileng lits'ebetsong tsa kabo ea ka tlas'a lefatše le lits'ebetsong tsa ka ntle moo ho pepeseha ha tikoloho le ts'ireletso ea ts'ebetso li tlamehang ho laoloa ka hloko.

2.1 Tanka le Sebaka se Koaletsoeng

Letlapa-tanka ea transfoma e cheselitsoeng ka botlalo, e tiisitsoe ka botlalo, e hahelletsoeng hore e tšoarelle le ho hlekefetsoa-, e loketseng ho kengoa ka ntle. Menyako e sirelelitsoe ka liboutu tsa penta le liloko tse 3-lintlha tsa vault; Qetello e tšoeu e koahetsoeng ka phofo (RAL 9003) e fana ka khanyetso khahlanong le ho pepeseha ha tikoloho, ho bola le ho senyeha ha UV.

2.2 Sistimi ea Insulation

Transformer e sebelisa FR3 ea tlhaho ea ester insulation fluid. Li-windling tsa mantlha le tsa bobeli li entsoe ka aluminium 'me li entsoe ka insulated hore li sebetsane le mekhahlelo e 'meli-ho{3}}ho{3}}mohato le mohato-ho-khatello ea motlakase fatše. Ho feta moo, yuniti e na le tšireletso e tiileng ea "electrostatic shield" lipakeng tsa lifensetere tsa mantlha le tsa bobeli, tse fokotsang-khatiso ea khafetsa le ho phahama ha motlakase.

03 Tsamaiso ea Tlhokomelo le Tšireletso

3.1 Tšireletso le Tlhokomelo ea Motlakase

Ho netefatsa ts'ebetso e bolokehileng le e ts'epahalang, sesebelisoa sa phepelo ea motlakase o mahareng se na le likarolo tse ngata tsa ho beha leihlo le ts'ireletso tse kentsoeng ka har'a sebaka se ka ntle sa lebokose la transformer. Lintlha tsa bohlokoa li kenyelletsa:

• Thebe e thehiloeng ea electrostatic
• Boemo ba oli, mocheso oa oli, le litekanyo tsa khatello ea tanka
• Valofo ea khatello ea khatello bakeng sa tšireletso e feteletseng
• Li-Surges arresters
• Libese tsa koporo bakeng sa ho hokahanya le li-fuse tsa ka ntle
• Li-switches tsa khefu ea mojaro

Sesebelisoa	Mosebetsi
Tekanyo ea boemo ba oli	E lekola boemo ba oli ea insulation
Mocheso oa Mocheso oa Oli	E lekola mocheso o sebetsang oa transformer
Tekanyo ea Khatello ea Tanka	E lemoha liphetoho tsa khatello ea ka hare
Seqhubu sa ho Imolla Khatello	E sireletsa khahlanong le khatello e feteletseng ea ka hare

Lisebelisoa tsena tsa ho beha leihlo li fana ka ponahalo e tsoelang pele ea ts'ebetso, e lumellang lihlopha tsa tlhokomelo ho tseba mathata a ka bang teng pele li fetoha liphoso tsa ts'ebetso. Tlhokomelo e thibelang e matlafatsa ts'epehi le ho netefatsa botsitso ba nako e telele- ba marangrang a li-transformer tsa motlakase o mahareng. Ho phaella moo, basebetsi ba ka itšoara ka potlako maemong a sa tloaelehang, ba fokotsa nako ea ho theoha.

3.2 Likarolo tsa Phetoho le Tšireletso

Transformer e ts'ehetsa ho sebelisana le moreki-ho fanoe ka lisebelisoa tsa ts'ireletso tsa kantle, ho kenyeletsoa Eaton Bussmann High-Speed ​​Fuse 170M series, e etselitsoeng ho fana ka karabelo e potlakileng ha mathata a motlakase. Yuniti e kenyelletsa:

• Li-switch tse tharo-tse peli tse peli
• Libese tsa koporo bakeng sa likhokahano tsa fuse
• Li-surges arresters bakeng sa tšireletso ea lehalima le leqhubu

Tokisetso ena e lumella transfoma e kentsoeng ka mekhahlelo e meraro ho arola liphoso tsa motlakase ka mokhoa o sireletsehileng ha e ntse e tsoela pele ho tsoela pele sebakeng se setseng sa marang-rang. Ho feto-fetoha ho hokahaneng le ts'ireletso li netefatsa karabelo e potlakileng ea liphoso, ts'ireletso e tšepahalang ea sistimi, le phano ea motlakase e sa sitisoeng, e etsa hore lebokose la ka ntle la transformer le tšoanelehe haholo bakeng sa ts'ebeliso ea-mesebetsi ea sekala le ea liindasteri tsa PV.

06 Likopo tse Tloaelehileng

Joalo ka lebokose la li-transformer tsa kantle, mochini ona oa pad mounted transformer o etselitsoe ho kengoa libakeng tse fapaneng tse fapaneng tsa motlakase oa motlakase o mahareng, ho kenyeletsoa lits'ebetso tsa motlakase oa indasteri, lits'ebetso tsa ts'ebeliso, lisebelisoa tsa matla a tsosolositsoeng, le marang-rang a kabo ea khoebo moo ho hlokahalang ho kenya transfoma e bolokehileng kantle.

Lisebelisoa tse tloaelehileng li kenyelletsa:
• Utility medium-voltage distribution system
• Kabo ea matla a indasteri
• Lisebelisoa tsa matla a ka nchafatsoang, ho kenyeletsoa mapolasi a solar PV
• Merero ea meaho le ea khoebo
Libakeng tsena, transformer e fana ka phetolo ea motlakase e sebetsang hantle ha e ntse e boloka ts'epahalo e phahameng ea ts'ebetso, hape e nolofalletsa ho kopanya habonolo le likarolo tsa motlakase tsa lebokose la motlakase.

07 Sebaka le Kakaretso

Ka har'a lisebelisoa tsa motlakase tsa projeke, lebokose la 2660 kVA outdoor transformer le sebetsa e le sesebelisoa sa mantlha sa motlakase o mahareng, se fetolelang utility medium-motlakase oa motlakase hore e be boemo ba motlakase o sebetsang bakeng sa lits'ebetso tsa motlakase tse tlase, ha ho ntse ho netefatsa ts'ebetso e bolokehileng le e tsitsitseng ka moralo oa eona oa IEEE{2}} o lumellanang le sistimi ea FR3, le lisebelisoa tse kopaneng tsa ts'ireletso. Transformer e theha yuniti e bohareng ea phetolo ea matla ka har'a marang-rang a phepelo ea projeke, hape e sebetsa ka tšebelisano le yuniti ea motlakase ea 150 kVA e thusang ho netefatsa phepelo ea motlakase e tšepahalang, e tsoelang pele.
