50 kVA Transformer Utility Pole-13.8 / 0.24 kV|Guyana 2025

01 Kakaretso

1.1 Semelo sa Morero

Ka 2025, re ile ra fana ka likarolo tse 36 tsa 50 kVA-li-phase pole{1}} li-transformer tse kentsoengho bareki ba nako e telele-Guyana, ho latela odara e atlehileng ea pele ea mofuta o tšoanang ka 2024. E hahiloe ho latela maemo a IEEE le ANSI C57.12.00, transformer ka 'ngoe e na le motlakase oa mantlha oa 13,800 V, motlakase oa bobeli oa 120/240 V, subtractive polarity, le sehlopha sa vector Ii0. E entsoe ka li- windings tsa koporo, liyuniti li fana ka 2% impedans, 'me ha li na{9}}load tap changer (NLTC) e nang le ±2×2.5% ea liphetoho (10% kakaretso). Ha -tahlehelo ea mojaro e filoe lintlha tsa 160 W, 'me tahlehelo ea mojaro ho 512 W, e netefatsa ts'ebetso e tšepahalang bakeng sa lits'ebetso tsa phepelo ea lisebelisoa.

Odara ena ha e tiise feela tšepo ea bareki ba rona ho botsebi ba rona ba botekgeniki le botsitso ba sehlahisoa empa hape e matlafatsa boteng ba rona lekaleng la lisebelisoa tsa Guyana. Kabo e atlehileng ya diyuniti tsena e tshehetsa ntshetsopele ya meralo ya lehae le ho matlafatsa marangrang a kabo ya matla a ditoropo le ditoropong ka ho romelwa ha transfoma e tshepehang.lisebelisoa tsa lisebelisoa.

02 Tlhahiso

2.1 Magnetic Core

Mokotla oa maqeba, o entsoeng ka mokhoa o tsoelang pele o ikemetseng; e boloka ho kheloha ho le tlase, ts'ebetso ea makenete e ts'oanang. Compact, e batlang e le bobebe, e lekanang palo{1}}litlhophiso tse kanngoeng; matla a mochine a lula a tiile, a tsitsitse tlas'a ho sisinyeha kapa liphetoho tsa mojaro. E netefatsa hore transformer e sebetsa ka botshepehi, nako e telele-.

2.2 Transformer Windings

Maqhubu a latela lintlha tsa IEEE le ANSI; high{{0}voltage e sebelisa copper foil-kabo ea motlakase e betere, e tlase-terata ea koporo e nang le matla a tlase, e matla khahlano le-li-circuits tse khutšoane. Automation e boloka li-coil li tsitsitse; boleng bo ka tšeptjoang, ts'ebetso e ka tsejoang esale pele. Lera le leng le le leng le hlahlobiloe, le lumellane, le loketse ho tlatsoa ka oli.

2.3 Tanka ea Transformer

Tanka ea tšepe e bonolo, e tiisitsoeng le ho lutla-e hlahlobiloe; matla a lekaneng bakeng sa ho tshosa, ho thothomela ha sepalangoang. Li-radiator tse nang le makotikoti mahlakoreng ka bobeli, li thusa ho senya mocheso ka katleho; e boloka transformer e pholile tlas'a mojaro o boima kapa mocheso o phahameng oa tikoloho. E sireletsa core, windings, tshebetso ka kakaretso e lula e tsitsitse, e bolokehile.

2.4 Ho Kena le Tlhahlobo ea ho Qetela

Li-core le windings li le teng, oli e tlatsitsoeng bakeng sa ho pata le ho pholisa; Lihlahla tsa HV/LV, valve ea ho imolla khatello, mochine oa ho fetola pompo, liteishene tsa fatše, li-radiator tse kentsoeng ka mor'a moo. Ka ntle e hloekisitsoe, liphahlo li hlahlojoa; lileibole, lintlha tsa nameplate, litšoantšo tsa methapo li netefalitsoe-ntho e 'ngoe le e 'ngoe e hlahlobiloeng pele e fihla, e loketse ho sebetsa.
