Igazi Lokuphila Lama-Transformers: Kusukela Kuwoyela Wezimbiwa Kuya Kuma-Esters Emvelo

Isingeniso

Uwoyela we-transformer uvame ukubizwa ngokuthi "igazi" le-transformer. Uyavikela, upholise, uvikele, futhi uxilonge ngisho nokuxilonga. Sekuyiminyaka engaphezu kwekhulu, uwoyela wamaminerali otholakala ku-petroleum ubelokhu uyindlela ejwayelekile yokukhetha. Kodwa ukukhathazeka okwandayo kwemvelo kanye nezidingo zokuphepha emlilweni kuye kwaholela ekuthuthukisweni kwezinye izindlela—okuphawuleka kakhulu, uwoyela we-ester wemvelo otholakala emithonjeni yemifino.

Lesi sihloko silandelela ukuvela koketshezi lokuvikela i-transformer futhi sichaza ukuthi lokhu kungafani kusho ukuthini kochwepheshe bokuthenga.

Ingxenye Yokuqala: Izindima Eziningi Zamafutha E-Transformer

Ukuvikela.Indima eyinhloko ukuhlinzeka ngokushisa kagesi phakathi kwezingxenye eziphilayo. Amandla ayo aphezulu e-dielectric avimbela ama-short circuits kanye nokuwohloka kukagesi.

Ukupholisa.Uwoyela ujikeleza ngama-windings kanye ne-core, uthwala ukushisa uye kuma-radiator lapho uhlakazeka khona emoyeni.

Ukucima i-Arc.Uma kwenzeka iphutha langaphakathi, uwoyela uyasiza ekucimeni i-arc ephumayo, ukuvimbela izinkinga ezincane ukuthi zingabi zimbi.

Isivikelo.Uwoyela wakha isithiyo phakathi kwezingxenye zensimbi nomoya-mpilo, okuvimbela ukugqwala.

Ukuxilongwa.Uwoyela usebenza njengomthwali wolwazi. Ukuhlaziywa kwegesi encibilikisiwe kulinganisa amagesi akhiqizwa yizinhlobo ezahlukene zamaphutha, okunikeza isixwayiso kusenesikhathi sezinkinga ezikhulayo.

Ingxenye Yesibili: Uwoyela Wezimbiwa—Indinganiso Yakudala Yekhulu

Njengoba ihlungiwe ngophethiloli ongahluziwe, uwoyela wamaminerali unikeza izinzuzo ezintathu ezibalulekile: ukutholakala komhlaba wonke, izindleko eziphansi, kanye namandla amahle kakhulu e-dielectric.

Kodwa-ke, inemikhawulo engokwemvelo. Indawo yayo yomlilo iphansi kakhulu—cishe ku-145°C kuya ku-160°C—okudala ingozi yomlilo ezindaweni ezinabantu abaningi. Iyabola kancane kancane, ngokuvamile amaphesenti angu-30 kuphela, okusho ukuthi ukuchitheka kungabangela umonakalo wemvelo wesikhathi eside. Futhi njengomkhiqizo kaphethiloli, ayinakuvuselelwa.

Ingxenye Yesithathu: Ama-Esters Emvelo—Indlela Eluhlaza Okwehlukile

Etholakala ku-soya, imbewu ye-rapeseed, kanye namanye amafutha emifino, ama-ester emvelo avele njengendlela ehamba phambili.

Ukuphepha Komlilo.Ama-flash points adlula ama-300°C—okungaphezu kokuphindwe kabili kwamafutha amaminerali—okwenza afaneleke kakhulu ekufakweni emadolobheni nangaphakathi.

Ukuhambisana Kwemvelo.Zibola kalula, zifinyelela amazinga okuwohloka angama-97% noma ngaphezulu phakathi namasonto.

Impilo Ende Yokuvikela Ukushisa.Iphepha elicwiliswe ku-ester yemvelo lingahlala isikhathi eside izikhathi ezingu-2.5 kuya kwezingu-5 kunaku-oyela wamaminerali ngaphansi kokucindezeleka okufanayo kokushisa. Ama-ester emvelo amunca amanzi amaningi abengalimaza iphepha futhi akhe izibopho ezivikelayo nama-molecule e-cellulose.

Izifundo ziqinisekisa lezi zinzuzo. Ku-100°C ngezikhathi ezinde, i-ester yemvelo igcine i-voltage ephezulu yokuqhekeka kunamafutha amaminerali ngenkathi ibonisa amandla aphezulu okudonseka kanye nokumelana okuzinzile.

Ingxenye Yesine: Ngale Kwama-Esters Emvelo—Ama-Esters Okwenziwa kanye Nobuchwepheshe Obusha

Ezimweni ezibandayo kakhulu kanye nezigaba ze-voltage eziphezulu kakhulu, ama-ester okwenziwa anikeza ukuzinza okuthuthukisiwe kwe-oxidation kanye nokusebenza kwezinga lokushisa eliphansi ngenkathi egcina izinzuzo zemvelo.

Umngcele wakamuva uhilela ubuchwepheshe be-nanotechnology. Izinhlayiya ezincane ze-titanium dioxide zinganciphisa iphuzu lokuthulula kusuka ku--5°C kuya ku--32°C, okuvumela ukusetshenziswa kwesimo sezulu esibandayo. Ama-nanosheet e-hexagonal boron nitride athuthukisa ukuhanjiswa kokushisa ngamaphesenti afinyelela ku-40. Izinhlayiya ezihlanganisiwe ze-iron-copper zandisa i-voltage yokuqhekeka ngamaphesenti angu-32. Lokhu kuguqulwa kukhomba ikusasa lapho ama-ester elingana noma edlula khona uwoyela wamaminerali kuzo zonke izigaba zokusebenza.

Ingxenye Yesihlanu: Izinto Okumelwe Zicatshangelwe Ngokukhetha Kwabathengi

Indawo Yokusebenzisa.Ezindaweni zangaphakathi, zasemadolobheni, noma ezizwela imvelo, ama-ester emvelo aqinisekisa intengo yawo ngokuphepha emlilweni kanye nokunciphisa umthwalo wemfanelo.

Isimo sezulu.Ama-ester emvelo anokuthambekela okuphezulu kunamafutha amaminerali, okungathinta ukupholisa ezindaweni ezibandayo. Ubuchwepheshe bokwengeza bunciphisa lesi sikhala.

Izindleko vs. Inani Lomjikelezo Wokuphila.Ama-ester emvelo abiza kakhulu ekuqaleni, kodwa isikhathi eside sokuvikela ukuvikela singanciphisa izindleko zobunikazi eziphelele emashumini eminyaka.

Ukuthobela Izindinganiso.I-IEC 60296 ihlanganisa uwoyela wamaminerali; i-IEC 62770 ihlanganisa ama-ester emvelo. Abathengi kufanele baqinisekise ukuthi uketshezi luhlangabezana nezidingo ezifanele.

Isiphetho

Uwoyela we-transformer ushintshe kusukela kumkhiqizo olula we-petroleum waba uketshezi oluthuthukisiwe oluklanywe ngendlela eyinkimbinkimbi. Ama-ester emvelo manje anikeza ukuphepha komlilo, ukuhambisana kwemvelo, kanye nokuphila isikhathi eside kokuvikela uwoyela wamaminerali ongenakukwazi ukufana nawo. Ama-ester okwenziwa asunduza imingcele yokusebenza phambili. Kwabachwepheshe bokuthenga, ukuqonda lezi zinketho kubalulekile ekwenzeni izinqumo ezinolwazi.
