630 kVA 3 Phase Dry Type Transformer-6.6/0.55 kV|Afrika Boroa 2025

01 Kakaretso

1.1 Semelo sa Morero

Transformer ea mofuta o omileng ea 630 kVA e ile ea tlisoa Afrika Boroa ka 2024; matla a lekantsoeng a transformer ke 630 kVA. Matla a phahameng a motlakase oa mofuta ona o omileng ke 6.6 kV, 'me matla a tlaase ke 0.55 kV. Transformer ena e phahameng ea motlakase ea mofuta o omileng e na le mochini o fetolang pompo e se nang moroalo, sebaka sa ho thepha ke ± 2 * 2.5% ka lehlakoreng la mantlha. Pholiso ke KNAF, ba thehile sehlopha sa vector sa Dyn11.

Li-transformer tsa mofuta oa resin cast dry{0} li etella pele moralong oa transformer, li fana ka motsoako o nepahetseng oa tšebetso ea motlakase le ea mochini. Mohaho oa bona o tšoarellang, o fihletsoeng ka ho koala li-winding ka epoxy resin, o fana ka matla le polokeho ea mochini o ke keng oa lekanngoa, oa bohlokoa bakeng sa ho fihlela lipheo tsa tikoloho le ts'ireletso.

E etselitsoe tikoloho e thata, -li-transformer tse bonolo li na le-tlhokomelo, oli{2}meralo e sa lefelloeng e fokotsang litšenyehelo tsa ts'ebetso. Lelakabe la tsona-le sa sebetseng,{5}}le itimang-li tiisa maemo a holimo a polokeho, athe moralo o kopaneng o boloka sebaka sa bohlokoa sa ho kenya.

Ka ho sebelisa{{0}lisebelisuoa tsa boleng bo holimo tsa ho tsikitlanya le meaho e tiileng ea likhoele, li-resin tsa rona tse ommeng{1}}li fana ka ts'epahalo le ho tšoarella ha nako e telele. Khetha li-transformer tsa rona bakeng sa litharollo tsa motlakase tse sebetsang hantle, tse bolokehileng le tse tšoarellang tse u fang monyetla oa tlholisano litsamaisong tsa motlakase tsa sejoale-joale.

02 Tlhahiso

2.1 Ntlha ea bohlokoa

Transformer core e hahiloe ho tloha-boleng bo holimo, bo batang-bo kolokisitsoeng, ba lijo-thollo-ka tšepe ea silicon e tšekaletseng ka mehato-manonyeletso a marako ho fokotsa tahlehelo ea matla. E na le maoto a mararo a hlophisitsoeng ka sefofane se le seng 'me a hokahanngoa ke joko e thata. Leoto le leng le le leng ke selikalikoe 'me le hokahantsoe le lijoko, ha mokokotlo o hahiloe ka lehlakoreng la 45-degree ho fokotsa lerata le tahlehelo. E sirelelitsoe mme e sirelelitsoe ho senya ka ho roala resin.

Foreimi e na le likanale tsa tšepe tse holimo le tse tlase tse tšoereng konoko le likhoele hammoho, tse nang le likarolo tsohle tsa tšepe tse tlositsoeng ka ho bola{0}}pente ea epoxy e sa khoneng ho tšoarella nako e telele. Moralo ona o netefatsa ts'ebetso e sebetsang hantle le ho ts'epahala maemong a fapaneng.

2.2 Ho tsubella

Kaho ea mapheo e na le-likhondara tsa grade insulated tse hlophisitsoeng ka likarolo tse ngata le mekhahlelo ho fokotsa matla a phahameng a motlakase a nakoana. Maqhubu a phahameng{{2}a felloang ke matla a motlakase a kenngoa ka har'a vacuum mold ho sebelisoa komporo e tsoetseng pele{3}}mokhoa o laolehileng, ho etsa bonnete ba hore ha ho likheo ho likhoele.

Li-winding li matlafatsoa hape ka fiberglass ho matlafatsa matla a mochini. Ka mor'a ho kopanngoa, likhoele kaofela tse phahameng-li etsa liteko tse sa fellang ho netefatsa hore ha ho na letho-maemo a mahala le ho netefatsa hore{3}}lisebelisoa tsa boleng bo holimo li etsoa. Moralo ona o hlokolosi o tiisa ho tšoarella le ho ts'epahala maemong a boima.

2.3 Kopano ea ho qetela

Ho kenya li-coil: Li-resin tse lekiloeng-li- windings li behiloe ka hloko ka har'a foreime ea transformer, ho netefatsa hore ho na le maemo a nepahetseng.

Kopanyo ea Konokono: Li-winding li kenngoa ka mokhoa o sireletsehileng ho ea bohareng ho fokotsa khatello ea kelello le ho netefatsa botsitso.

Lihokelo tsa Motlakase: Likhokahano tsa motlakase li thehoa ka mokhoa o nepahetseng, li kopanya li-windings ho li-terminals tsa transformer le ho netefatsa hore li kopantsoe hantle le tsamaiso ea motlakase.

Ho tšela Resin: -epoxy resin ea boleng bo holimo e tšeloa holim'a kopano, e fana ka tšireletso ho mongobo le ho matlafatsa mokelikeli.

Mokhoa oa ho phekola: Transformer e phekoloa ho thatafatsa resin, ho netefatsa thepa e lakatsehang ea mochini le motlakase.

Sefetoleli sa rona sa "resin cast dry type" ke tharollo ea motlakase e sebetsang hantle le e ts'epahalang e etselitsoeng ho khahlametsa-litlhokahalo tse phahameng tsa ts'ebetso ea liindasteri le khoebo. E entsoe ka-ka resin ea epoxy ea boemo bo holimo, 'me e sebelisa mokhoa o hlokolosi oa ho akhela, transformer ka 'ngoe e etsa liteko tse matla ho netefatsa hore e na le mokelikeli o ikhethang le ho thibela mongobo. Li-transformer tsa rona li na le litšobotsi tse ntle tsa taolo ea mocheso, tse nolofalletsang ts'ebetso e tsitsitseng maemong a fapaneng a tikoloho ha li ntse li fokotsa litšenyehelo tsa tlhokomelo le ho lelefatsa bophelo ba lisebelisoa. Moralo o kopaneng le ts'ebetso e phahameng ea ts'ireletso ea mochini o omileng oa resin cast o e etsa khetho e nepahetseng bakeng sa lits'ebetso tsa sejoale-joale tsa motlakase, ho netefatsa phetisetso ea matla e bolokehileng le e sebetsang hantle. Khetha li-transformer tsa rona ho netefatsa ts'ebetso e tsoelang pele le e sebetsang ea sistimi ea hau ea matla.
