167 kVA Pole Mounted Distribution Transformer-24.94/0.12/0.24 kV|Canada 2024

01 Kakaretso

1.1 Tlhaloso ea Morero

167 kVA karolo e le 'ngoe ea pole mounted transformer e ile ea isoa Canada ka 2025. Matla a lekantsoeng a transformer ke 167 kVA e nang le pholiso ea ONAN. Motlakase oa mantlha ke 24.94GrdY/14.4 kV e nang le ± 2 * 2.5% tapping range (NLTC), motlakase oa bobeli ke 0.12 / 0.24 kV, 'me ba thehile sehlopha sa vector sa Ii6.

Pole ena ea 167kVA{1}}e behiloeng ka transformer ke tharollo e matla le e ts'epahalang e etselitsoeng ho ajoa ha motlakase ka mokhoa o hloahloa linetwekeng tsa motlakase tse holimo. E na le likarolo tsa bohlokoa tsa ts'ireletso le ts'ebetso, e netefatsa ts'ebetso e bolokehileng le e tsitsitseng maemong a fapaneng a tikoloho. Likarolo tse ka sehloohong li kenyelletsa sesebelisoa sa ho imolla khatello ea ho fokotsa liphoso tsa ka hare ka ho lokolla khatello e feteletseng, litšehetso tsa ho ts'oaroa ha li-surges tse ntseng li eketseha ho sireletsa khahlanong le overvoltages, le tsamaiso ea Internal Fault Detection (IFD) bakeng sa ts'ebetso e ntlafetseng le ho tsebahatsa phoso pele ho nako.

Ho feta moo, transformer e na le-circuit tap changer e timang, e lumellang ho feto-fetoha ha sekhahla sa motlakase hore se lumellane le litlhoko tse sa tšoaneng tsa phalliso ha-e matlafatsoa. E kopane, e tšoarella, 'me e entsoe bakeng sa tlhokomelo e bonolo, yuniti ena e loketse lisebelisoa le lits'ebetso tsa indasteri tse hlokang kabo ea motlakase e tšepahalang.

02 Tlhahiso

2.1 Konokono

Lithapa tsa tšepe tsa silicon li lula li holisoa ka mokhoa o nepahetseng hore e be karolo ea selikalikoe kapa e pota-potileng-karolo (mohlala, khutlonnetsepa kapa e haufi-ea chitja) ho etsa potoloho e koetsoeng ea makenete. Ka mor'a matsoelintsoeke, annealing e etsoa ho imolla khatello ea kelello le ho ntlafatsa thepa ea makenete. Tsela e sa tsitsang ea makenete e felisa tahlehelo e eketsehileng e bakoang ke ho se lumellane ha matla a khoheli ho manonyeletso a li-cores tsa laminated. Potoloho ea makenete e koetsoeng e fokotsa ho lutla ha flux, e netefatsa phepelo e ts'oanang ea matla a khoheli, ka katleho ea mantlha e fetang 99%.

2.2 Ho tsubella

Sebopeho sa LV foil + HV wire winding configuration ho palo{1}}transformer e palamisitsoeng e fumana tekanyo e nepahetseng ea ts'ebetso e phahameng, e ts'epahalang, le litšenyehelo tse tlase tsa tlhokomelo. Sebopeho se bataletseng se eketsa sebaka se pholileng, se matlafatsang katleho ka oli kapa moea o pholileng. Multi-layer insulation optimize kabo ea motlakase hantle, ho fokotsa partial discharge (PD). Maqhubu a foil a fokotsa deformation ea radial; HV wire windings e sebelisa sekontiri se matlafalitsoeng bakeng sa ho phalla ho feteletseng. Aluminium foil e fokotsa boima ba 'mele, e loketseng bakeng sa ho phahamisa lipalo.

2.3 Tanka

Lihlahisoa tsa rona li kopana le sehlopha sa C4 corrosion resistance.

1- Ntlafatso ea Taolo ea Ts'ebetso Re matlafalitse ts'ebetso ea rona ea ho roala ka mokhoa o ntlafalitsoeng oa ho lokisa bokaholimo, ho hloekisa ka thata, le liprothokholo tsa kalafo ea lik'hemik'hale ho felisa tšilafalo ea substrate, ha re ntse re netefatsa lintlha tse netefalitsoeng tsa botenya.

2- 2-Kaonafatso ea Sebopeho Re kentse tšebetsong kalafo e tiisitsoeng ea seam ea weld manonyeletsong 'ohle a bohlokoa ho thibela ho kenella ha mongobo ka har'a li-transformer tsa kahare ka nepo.

2.4 Qetello e Tšoarellang

 

Li-transformer li ne li pentiloe ka thata ho ea ka litlhaloso. Likarolo tsa tšepe li ile tsa hloekisoa esale pele 'me tsa hloekisoa ka botlalo ho tsoa li-burrs, mafome le litšila. Lipente tse nang le tokelo ea molao kapa lipente tsa phofo-polyester kapa polyurethane{3}li ne li sebelisoa ka mokhoa o ts'oanang, li koahela likarolo tsohle le ho kopanya tanka le kampeng bakeng sa tšireletso e felletseng. ASA 70 grey finish e kopana le ANSI C57.12.28 mme e feta tekolo ya ho fafatsa letswai ya dihora tse 1500{8}, e nang le bokahodimo bo senang lerole mme bo sa angwa ka mora ho penta.

2.5 Kopano ea ho Qetela

1. Kopano e Matsoho

Kenya li- windings tsa HV le LV ka tatellano mokokotlong oa leqeba, ho netefatsa boemo bo nepahetseng ba likarolo tsa ho pata le ho tiisa ka mochini.

2. Lihokelo tsa Motlakase

Hokela li-lead (li-terminals tsa HV/LV, tap changer) ka tjheseletsa kapa bolting ho tlatsa li-circuits tsa motlakase lipakeng tsa matsoelintsoeke, ebe u sheba hore na ho hanana le mang.

3. Ho Omisa Likhoele{1}

Mokhoa oa ho Omisa Oven: Beha karolo e sebetsang e kopaneng (core + windings) ka ontong e omisang hore ho be le vacuum e chesang-moea o potoloha kapa mouoane{2}}o omisa ka likhato tse 105-130 ka lihora tse 48-72 ho fihlela mongobo o kenang o ka Tlase kapa o lekana le 0.5%.

4. Ho kenya Tanka
