750 kVA Kantle Pad Mounted Transformer-34.5/0.48 kV|USA 2024

01 Kakaretso

1.1 Semelo sa Morero

750 kVA phase three phase mounted transformer e ile ea isoa Chaena ka 2024. Matla a lekantsoeng a transformer ke 750 kVA e nang le pholiso ea ONAN. Motlakase oa mantlha ke 34.5GrdY/19.92 kV e nang le ± 2 * 2.5% tapping range (NLTC), motlakase oa bobeli ke 0.277 / 0.48 kV, ba thehile sehlopha sa vector sa YNyn0.

The-phase pad-mounter mounter e na le moetso o koetsoeng, 'me e behiloe fatše, e leng se etsang hore ho be bonolo ho hokela lithapo. Sebaka se kampetsoeng sa transformer ha se kenelle metsi ebile ha se na lerole, se etsa hore se lokele maemo a leholimo a fapaneng.

02 Tlhahiso

2.1 Konokono

Mokotla oa-phase ea mekhahlelo e meraro-e kentsoeng transformer e sebelisa kholomo-moetso oa mofuta, o nang le maoto a mangata a kopantsoeng hammoho ho fana ka tsela e kholo ea makenete. Moralo oa mantlha ke loop e koetsoeng, e eketsang tšireletso ea matla a khoheli le ho netefatsa phetoho e nepahetseng ea matla lipakeng tsa ho kenya le ho tsoa. Moralo oa mantlha hangata o sebelisa tlhophiso e ts'oanang ho netefatsa kabo e leka-lekaneng ea-mohato oa maqhubu a mararo, ho fokotsa lerata le ho thothomela nakong ea ts'ebetso. Khetho ea lisebelisoa tsa mantlha le moralo o fana ka conductivity e ntle ea mocheso, e thusang ho senya mocheso nakong ea ts'ebetso le ho boloka mocheso o nepahetseng oa ho sebetsa.

2.2 Ho tsubella

Maqhubu a na le lihlopha tse tharo tsa mapheo a tšoanang a tsamaisanang le-mohato oa motlakase oa mekhahlelo e meraro (A, B, le C mehato). Moralo ona o netefatsa tekatekano le tshebetso dipakeng tsa mohato o mong le o mong, ho thusa ho fana ka matla a tsitsitseng a{2}mohato a mararo. Li-winding tsa e hangata li entsoe ka aluminium joalo ka lisebelisoa tsa conductor. Li-winding li koahetsoe ka lisebelisoa tsa ho kenya letsoho ho thibela lipotoloho tse khutšoanyane le ho lutla. {{6}Meetso ea boleng bo holimo e ka fokotsang tahlehelo ea hona joale le tahlehelo ea mocheso, ea ntlafatsa ts'ebetso ea kakaretso ea transformer.

2.3 Tanka

Tanka ea oli e na le moralo o tiisitsoeng ho thibela ho tsoa ha oli, ha o ntse o qoba ho kenella ha mongobo kapa litšila, ka hona ho boloka botsitso le bohloeki ba oli. Oli ea transformer ka har'a tanka e na le thepa e ntle haholo ea ho itšireletsa, e thibelang hantle liphoso tsa motlakase le ho lutla, ho netefatsa ts'ebetso e bolokehileng ea transformer. Tanka e na le litekanyo tsa boemo ba oli tse fanang ka tlhahlobo ea nako-ea 'nete ea boemo ba oli, ho netefatsa hore e lula sebakeng se tloaelehileng ho boloka pholiso e sebetsang hantle. Moralo oa tanka ea oli o kenyelletsa li-valve tsa khatello ea khatello ho thibela khatello e feteletseng ea kahare e ka lebisang ho senyeha ha tanka kapa ho phatloha.

2.4 Kopano ea ho Qetela

Ho Kena ha Maqhubu: Kenya li-winding tse lekiloeng ka har'a tanka ea oli, ho etsa bonnete ba hore li hokahane ka nepo le litsela tse nepahetseng.
