Impikiswano eqhubekayo phakathi kwama-transformer e-aluminium kanye nethusi ithonye izinqumo zokuthenga kuzo zonke izimboni, kusukela ezinkampanini zezinsiza kuya ezindaweni zokukhiqiza.

Lokhu kuhlaziywa okuphelele kuhlola izici eziyisisekelo kanye nemininingwane yobuchwepheshe ehlukanisa ama-transformer e-aluminium kanye nethusi, kuhlola izici ezibalulekile ezifaka phakathi ukuhanjiswa kwamandla, izakhiwo zokushisa, ukucatshangelwa kobukhulu, kanye nezicelo ezisebenzayo emikhakheni eyahlukene. Ukuqhathanisa kwethu okuningiliziwe kuzosiza ochwepheshe ukwenza izinqumo ezinolwazi ngokusekelwe ezidingweni ezithile zephrojekthi kanye nemikhawulo yokusebenza.

Kuyini i-Aluminium Transformer

I-transformer ye-aluminium isebenzisa ama-winding e-aluminium esikhundleni sethusi lendabuko kokubili kuma-coil ayo ayinhloko nawesibili. Ingaphakathi le-transformer lihlala lakhiwe ngama-lamination ensimbi ye-silicon, kuyilapho izinto zokuqhuba ama-windings kuyi-aluminium ehlanzekile kakhulu enezakhiwo zikagesi ezithile ezifanele ukudluliselwa nokusabalalisa amandla.

Ama-winding e-aluminium adlula ezinqubweni ezikhethekile zokukhiqiza ukuze kugcinwe izici zikagesi ezifanele. Abakhiqizi bavame ukwandisa indawo enqamulayo yama-winding e-aluminium cishe ngo-60% uma kuqhathaniswa nama-equivalent ethusi ukuze babuyisele ukuhanjiswa kwe-aluminium okuphansi. Lokhu kuguqulwa komklamo kuqinisekisa amandla anele okuthwala ugesi ngenkathi kugcinwa amazinga okusebenza kwe-transformer.

Ama-transformer e-aluminium anamuhla afaka izinhlelo zokushisa ezithuthukisiwe kanye nezindlela zokupholisa ukuphatha amazinga okushisa okusebenza ngempumelelo. Ama-windings aqukethe izinto zokushisa ezisezingeni eliphezulu, kufaka phakathi iphepha le-kraft kanye namafutha amaminerali, ahlinzeka ngokuhlukanisa ugesi kanye nokushabalalisa ukushisa. Lawa ma-transformer avame ukusebenzisa amathangi ahlanganisiwe kanye nezinhlelo ze-radiator ukuze kuthuthukiswe ukusebenza kahle kokupholisa.

Kuyini i-Copper Transformer

I-transformer yethusi isebenzisa abaqhubi bethusi ukuze ikwazi ukugoqa okuyinhloko nokwesibili. I-transformer isebenzisa ithusi le-electrolytic grade elinobumsulwa obuncane obungu-99.9%, okuqinisekisa ukuhanjiswa kukagesi okuphezulu kanye nezici zokudlulisa amandla ezithembekile. Ama-winding ethusi abonisa ukusebenza okufanayo kuzo zonke izimo zomthwalo ezahlukahlukene kanye namazinga okushisa okusebenza.

Umklamo wama-transformer ethusi uzuzisa ngezakhiwo zezinto ezingokwemvelo zethusi. Ama-windings agcina ubukhulu obuncane ngenxa yokuqhuba okuphezulu kwethusi, okuvumela ukusetshenziswa kahle kwesikhala ngaphakathi kwenhlangano ye-transformer. Ama-conductor ethusi anezimbozo ezikhethekile ze-enamel kanye nezinhlelo zokuvikela iphepha ezivimbela ama-short kagesi ngenkathi kusiza ukudluliselwa kokushisa okuphumelelayo.

Lawa ma-transformer asebenzisa amasu okugoqa anembile ukuze anciphise ukulahlekelwa kwamanje kwe-eddy futhi athuthukise ukuhlangana kwe-electromagnetic phakathi kwama-coil ayinhloko nawesibili. Ama-copper windings agcina ubuqotho bawo bomshini isikhathi eside, elwa nokuguquguquka ngaphansi kokucindezeleka kokushisa kanye namandla kagesi. Izinqubo zokukhiqiza zifaka phakathi ukucindezela ngokucophelela kanye nokulawula ukucindezeleka ukuqinisekisa ukusatshalaliswa okufanayo kokucindezeleka kukagesi nomshini kulo lonke ukuhlanganiswa kwama-winding.

Umehluko Obalulekile Phakathi Kwabaguquli Be-Aluminium Ne-Copper

Ukusebenza kukagesi

Ukuqhuba kukagesi kwethusi kumi ku-100% IACS (International Annealed Copper Standard), kuyilapho i-aluminium ifinyelela cishe ku-61% IACS. Lo mehluko usho ukuthi ama-transformer ethusi abonisa ukumelana okuphansi kukagesi, okuholela ekunciphiseni kokulahlekelwa kwamandla ngesikhathi sokusebenza. Ukuze babuyisele ukuguquguquka okuphansi kwe-aluminium, abakhiqizi kumele bandise indawo enqamulayo yama-windings e-aluminium cishe ngo-56% uma kuqhathaniswa nama-windings ethusi ukuze bafinyelele umthamo olinganayo wokuthwala ugesi.

Cost

Ama-transformer e-aluminium ngokuvamile abiza ngaphansi ngo-30-40% kunezimbangi zawo zethusi ngenxa yamanani aphansi ezinto zokusetshenziswa. Imakethe yezimpahla zensimbi ikhombisa ukuthi i-aluminium igcina intengo ephansi njalo ngekhilogramu uma iqhathaniswa nethusi. Kodwa-ke, ukuhlaziywa kwezindleko eziphelele kufanele kucabangele ukuthi ama-transformer e-aluminium adinga ama-winding amakhulu kanye nezinto zokuvikela eziningi ukuze kufezwe ukusebenza okufanayo.

Isisindo

Ubuningi be-aluminium obungu-2.7 g/cm³ uma buqhathaniswa nobethusi obungu-8.96 g/cm³ kwenza ama-transformer e-aluminium abe lula cishe ngo-50% kunezinithi zethusi ezilinganayo. Lo mehluko wesisindo unikeza izinzuzo ezibalulekile ekuthuthweni, ekufakweni, nasezidingweni zokusekelwa kwesakhiwo. I-transformer ye-aluminium engu-1000 kVA ngokuvamile inesisindo esingaphansi ngo-30-35% kune-equivalent yayo yethusi.

Usayizi

Ngenxa yokuthi i-aluminium ayinamandla okuqhuba kahle, ama-transformer asebenzisa ama-aluminium windings adinga ama-cores amakhulu nama-coil. Ukwanda kobukhulu ngokuvamile kusuka ku-15-25% uma kuqhathaniswa nama-transformer ethusi anesilinganiso esilinganayo. Lo mehluko wosayizi uthinta izidingo zesikhala sokufakwa kanye nokucatshangelwa kokupholisa. Isibonelo, i-transformer ye-aluminium engu-500 kVA ingadinga ivolumu engaphezulu ngo-20% kune-equivalent yayo yethusi.

Ukuqhuba Ukushisa

Ukushisa kwe-Copper okungu-401 W/m·K kudlula i-aluminium engu-237 W/m·K, okuvumela ukushabalaliswa kokushisa okuphumelelayo kuma-transformer ethusi. Lokhu kuphathwa kokushisa okuphezulu kuvumela ama-transformer ethusi ukuthi asebenze ngobuningi bamandla aphezulu ngaphandle kokushisa ngokweqile.

Ukuqina namandla

Ithusi libonisa amandla aphezulu okusebenza ngomshini ngamandla okudonseka angu-220-400 MPa uma kuqhathaniswa ne-aluminium engu-70-180 MPa. Lo mehluko uthinta ukuqina kwe-transformer ekucindezelekeni komshini ngesikhathi sokuthuthwa, ukufakwa, kanye nokusebenza. Ama-transformer ethusi abonisa ukumelana okungcono nokudlidliza kanye nokuguguleka komshini ngokuhamba kwesikhathi.

Ukuphumelela

Ukuqhuba okuphezulu kwethusi kuholela ekulahlekelweni kwamandla okuphansi kanye nezilinganiso zokusebenza kahle ezithuthukisiwe. Ama-transformer ethusi ngokuvamile abonisa ukusebenza kahle okuphezulu okungu-0.3-0.5% kunamayunithi e-aluminium afanayo. Ku-transformer engu-1000 kVA esebenza ngomthwalo ogcwele, lo mehluko wokusebenza kahle ungahunyushwa kuma-kilowatt-hours ayizinkulungwane eziningana alondolozwa minyaka yonke.

Yokuphila Isikhathi Eside Ise

Ama-transformer ethusi ngokuvamile agcina ubuqotho bokusebenza iminyaka engama-30-40, kuyilapho ama-transformer e-aluminium ephakathi kweminyaka engama-25-35 ngaphansi kwezimo ezifanayo. Lo mehluko wokuphila uvela ekumelaneni okukhulu kwethusi ne-oxidation kanye nokucindezeleka komshini. Izindawo zokuxhuma kuma-transformer e-aluminium zidinga ukulungiswa njalo ngenxa yemiphumela yokujikeleza kokushisa.

Izicelo

Ama-transformer ethusi avame kakhulu ezicelweni ezifuna ukuthembeka okuphezulu, njengezikhungo zezokwelapha, izikhungo zedatha, kanye nezinqubo zezimboni. Ama-transformer e-aluminium asetshenziswa kabanzi ezintuthukweni zokuhlala, ezakhiweni zezentengiselwano, kanye namanethiwekhi okusabalalisa izinsiza lapho ukulungiswa kwezindleko kubekwa phambili.
