100 kVA Pole ea Transformer Mounted-13.8 / 0.24 kV|Guyana 2025

01 Kakaretso

1.1 Semelo sa Morero

Pale ena ea 100 kVA single-mohato oa transformer e kentsoeng, e rometsoeng Guyana ka 2025, e entsoe ho latela maemo a IEEE le ANSI C57.12.00. Ka motlakase oa mantlha oa 13,800 V le motlakase oa bobeli oa 120/240 V, e loketse bakeng sa phano ea khoebo ea bolulo kapa e bobebe libakeng tsa mahaeng kapa litoropong moo ho hlokahalang -mokhahlelo o le mong. Pholiso ea ONAN, maqhubu a koporo, le polarity ea subtractive li netefatsa ts'epo e phahameng le ho tšoarella maemong a kantle. ±2×2.5% NLTC tap changer e lumella hore ho be le taolo e nyane ea motlakase, ho etsa hore e tšoanele libaka tse nang le ho feto-fetoha ha motlakase kapa phetiso e telele{14}}ea sebaka. Moralo o momahaneng, o nang le transfoma o sebetsa hantle haholo bakeng sa ditjeho{16}}ho romelwa hantle ditikolohong tse nang le palo e tlase ya batho.

02 Tlhahiso

2.1 Konokono

Ha ho etsoa li-transformer, mantlha e phetha karolo ea bohlokoa e le tsela e ka sehloohong ea ho phalla ha makenete, e amang ts'ebetso le katleho ka kotloloho. Setšoantšong, li-cores tse ngata tse pota-potiloeng li hlophisitsoe ka makhethe ka mor'a ho feta licheke le ho beha maemo. Basebeletsi ba latela mekhoa e tloaelehileng ho etsa bonnete ba hore lamination e thata, e lumellanang, ho lokisa li-cores bakeng sa kopano e nepahetseng ea li-coil le mohato o latelang oa kaho ea karolo e sebetsang.

2.2 Ho tsubella

Transformer ea 100kVA single phase pole mounted e sebelisa mapheo a koporo. The low voltage coil e nka foil winding e nang le{2}}conductivity foil ea koporo e phahameng, e nang le leqeba le tiileng le nang le lesela le nang le lesela. Mohatla o phahameng oa motlakase o sebelisa terata ea koporo e nang le enamelled, e nang le leqeba le nang le insulation pakeng tsa lihlopha. Ka mor'a ho tsoelipana, li-coil lia omisoa ebe lia phekoloa ho matlafatsa matla a ho koala le ho tšepahala ha nako e telele-.

2.3 Tanka

Tanka ea oli e bonolo ea tšepe, e nang le li-radiator tse entsoeng ka masenke mahlakoreng ka bobeli, e hlahlojoa ka hloko pele e kopana. Setšoantšong, basebetsi ba etsa licheke ka ho lekanya likarolo tsa bohlokoa, ba etsa tlhahlobo ea pono ho bona bofokoli kapa mathata a weld, le ho netefatsa boemo ba kalafo bo holimo. Litlhahlobo tsena tse phethahetseng li netefatsa hore tanka ea oli e kopana le litekanyetso tse hlokahalang bakeng sa ts'ebetso e tšepahalang ea li-transformer.

Transformer ena ea 100kVA single-phase pole{2}}e behiloe e loketse ho ajoa ka ntle libakeng tsa mahae kapa litoropong moo motlakase oa mantlha oa 13.8kV o theohelang ho 120/240V motlakase oa bobeli. E na le li- windings tsa koporo, pholiso ea tlhaho ea ONAN, le ±2×2.5% no{9}}load tap changer, e fana ka botšepehi bo phahameng le taolo ea motlakase e feto-fetohang{10}}e sebetsang hantle bakeng sa libaka tse nang le ho feto-fetoha ha motlakase kapa{11}}ho fihla ha motlakase ka nako e telele. Moralo oa eona o kopaneng le ho poma lipoleiti ha bonolo ho etsa hore e jelle litšenyehelo-bakeng sa libaka tse tlase{14} tsa batho ba bangata.

Haeba morero oa hau o hloka:

• Matla a tlase ho isa ho a mahareng a mokhahlelo a le mong-e le 'ngoe

• Ho kengoa lipalo ka ntle-kantle

• Matla a motlakase a tsitsitseng tlas'a likhoele tse feto-fetohang kapa tse atolositsoeng

• Li- windings tsa koporo tse sebetsang hantle le ho pholisa ka tlhaho ho fokotsa litšenyehelo tsa tlhokomelo

Transformer ena e ntle haholo. Ikopanye le rona bakeng sa lintlha tse ling le likhetho tsa ho iketsetsa.
