01 Kakaretso

1.1 Tlhaloso ea Morero

800kVA cast coil dry type transformer e ile ea isoa Afrika Boroa ka 2025. Matla a lekantsoeng a transformer ke 800 kVA e nang le pholiso ea KNAN/KNAF. Motlakase o ka sehloohong ke 6.6 kV o nang le ± 2 * 2.5% tapping range (NLTC), motlakase oa bobeli ke 0.55 kV, ba thehile sehlopha sa vector sa Dyn11.

Lefatšeng la kajeno, moo tsoelo-pele ea khoebo, polokeho, le ts'ebeliso e ntle ea matla e leng tsona tsa bohlokoa, mochini o bitsoang cast coil dry{0}} o eme e le motheo oa mokhoa oa sejoale-joale oa ho tsamaisa motlakase. E etselitsoe ho ts'epahala ho fetisisa, li-transformer tsena li fana ka khotso ea kelello e ke keng ea lekanngoa. Lelakabe la tsona-moetso oa epoxy-o kentsoeng ka thata{4}} o felisa likotsi tsa mollo, e leng se lumellang hore ho kenngoe ka mokhoa o sireletsehileng haufi le thepa ea hau e boima, e bolokang sebaka sa bohlokoa le ho fokotsa litšenyehelo tsa ho instola.

Re tsepamisitse maikutlo tabeng ea ho tšoarella le litšenyehelo tse tlase kaofela tsa thepa, li-cast coil transformer li na le meralo e phahameng-e fokotsang tahlehelo ea matla, e leng se lebisang ho bolokeheng ha ts'ebetso. Ha li hloke ho hlokomeloa 'me li hahiloe ho mamella maemo a thata ka ho fetisisa a indasteri, ho netefatsa hore ho na le motlakase o sa sitisoeng bakeng sa ts'ebetso ea hau ea bohlokoa-ho tloha ho lifeme tsa tlhahiso le merero ea matla a ka nchafatsoang ho ea litsing tsa khoebo le lisebelisoa tsa sechaba. Khetha theknoloji ea li-coil bakeng sa tharollo ea motlakase e bohlale, e sireletsehileng le e tšoarellang.

Ho thibela litsela tsa hona joale tsa eddy, li-laminations tse tšesaane li koahetsoe ka bonngoe ka lera la insulating. Ka mor'a ho bokellana, core e tlamahanngoa ka mokhoa o sireletsehileng 'me e thehiloe sebakeng se le seng, ho felisa kotsi ea ho potoloha ha maqhubu le ho netefatsa ts'ebetso e bolokehileng, e ts'eptjoang le e sebetsang hantle{3}.

2.2 Ho tsubella

Bakeng sa li-winding tsa transformer tse entsoeng ka "cast coil dry type", li-conductors li hlophisoa ka mokhoa o hlophisehileng 'me li kenngoa ka lisebelisoa tsa khalase pele, 'me li lateloe ke vacuum pressure casting e nang le mocheso-resistant epoxy resin compound. Maqhubu a folisitsoeng a etsa mokhoa o tiileng oa ho kenya letsoho o nang le matla a phahameng a dielectric le mocheso oa mocheso bakeng sa ho qhala mocheso hantle, empa hape o na le matla a matla a thibelang-tšilafalo le{3}}a thibela ho bola, a loketseng lisebelisoa tse fapaneng tsa ka hare le tsa ka ntle.

 

2.3 Kopano ea ho Qetela

Bakeng sa kopano ea transformer ea coil e omeletseng, motheo oa tšepe o behiloe ka thata pele. Li-windling{{1}tse tlang pele li tla kopanngoa holim'a motheo ka likaroloana tse tiisang boemo ba tsona. Likamano tse etellang pele lipakeng tsa matsoelintsoeke le li-terminals tsa kantle li entsoe, 'me litsamaiso tsa ho pholisa (joalo ka li-axial fans) lia kopanngoa. Ka mor'a moo, sebaka seo sea khomareloa, 'me -litlhahlobo tsa poso-ho kenyeletsoa liteko tsa ho hanyetsa le ho feto-fetoha ha mocheso-li etsoa ho netefatsa bots'epehi le ts'ebetso ea yuniti.

 

 

03 Teko

Liteko tsa 800kVA-6.6/0.55kV cast coil dry type transformer li lumellana le IEC 60076-1, 60076-3 le 60076-11 maemo a, a koahelang lintho tse tloahelehileng: tekanyo ea winding resistance (unbalance rate (unbalance rate D) kapa tekanyo e lekanang le 2%) kapa tekano ea voltage. ho kheloha ± 1/10), ho sitisa potoloho e khuts'oane / tahlehelo ea mojaro le tahlehelo ea moroalo / liteko tsa hajoale, tlhahlobo ea motlakase e sebelisitsoeng (HV 20kV / 60s, LV 5kV / 60s), tlhahlobo ea matla a ho mamella mocheso (1.1kV, 150Hz, 40s), le teko ea ho tsoa ka mokhoa o sa fellang (max 1p) ho feta 1p); litekanyetso tsohle tse lekantsoeng li fihlela litlhoko, ka sephetho sa "Pass".
