Ithonya Lokushisa Ekusebenzeni Kahle Kokuguqula

Isingeniso

Ukusebenza kahle kwe-transformer kuyisici esibalulekile ekusebenzeni kwezinhlelo zikagesi. Ama-transformer ayizingxenye ezibalulekile ezivumela ukudluliswa nokusatshalaliswa kukagesi emazingeni ahlukene kagesi. Ukusebenza kahle kwawo kudlala indima ebalulekile ekunciphiseni ukulahlekelwa kwamandla nokuqinisekisa ukutholakala kwamandla okuthembekile. Esinye sezici ezibalulekile ezithinta ukusebenza kahle kwe-transformer izinga lokushisa. Kulesi sihloko, sizohlola ithonya lokushisa ekusebenzeni kahle kwe-transformer kanye nemiphumela yalo ezinhlelweni zikagesi.

Ukuqonda Ukusebenza Kahle Kokuguqula

Ngaphambi kokuhlola umthelela wokushisa ekusebenzeni kahle kwe-transformer, kubalulekile ukuqonda ukuthi kusho ukuthini ukusebenza kahle kwe-transformer. Ukusebenza kahle kwe-transformer kubhekisela esilinganisweni samandla okukhipha amandla okufaka. Kuvezwa njengephesenti futhi kumele ukusebenza kahle kwe-transformer ekudluliseni amandla kagesi ngaphandle kokulahlekelwa okukhulu. Uma ukusebenza kahle kuphakeme, kunciphisa ukulahlekelwa kwamandla ku-transformer.

1. Umthelela Wokushisa Okumaphakathi Ekusebenzeni Kahle Kokuguqula

Izinga lokushisa elizungezile i-transformer lingathinta kakhulu ukusebenza kahle kwayo. Ama-transformer, ngesikhathi sokusebenza kwawo, akhiqiza ukushisa ngenxa yokulahlekelwa yi-core kanye nokulahlekelwa yithusi. Lokhu kulahlekelwa kubangela ukuthi izinga lokushisa le-transformer likhuphuke. Izinga lokushisa elizungezile, elimelela izinga lokushisa lendawo ezungezile, lingathinta ukupholisa kwe-transformer futhi, libe nomthelela ekusebenzeni kwayo kahle.

a) Izindlela Zokupholisa

Ukuze kugcinwe izinga lokushisa lokusebenza elifanele, ama-transformer athembele ezindleleni ezahlukene zokupholisa. Izindlela ezivame kakhulu zifaka phakathi i-convection yomoya yemvelo, i-convection yomoya ephoqelelwe, kanye nokupholisa ngoketshezi. Indlela yokupholisa incike kusayizi, isilinganiso, kanye nokusetshenziswa kwe-transformer. Kunoma ikuphi, izinga lokushisa elizungezile lithonya inqubo yokupholisa futhi kamuva lithinta ukusebenza kahle.

b) Umkhawulo Wokukhuphuka Kwezinga Lokushisa

Ama-transformer aklanyelwe ukusebenza ngaphakathi komkhawulo othile wokwenyuka kwezinga lokushisa. Lo mkhawulo unqunywa yizindinganiso zemboni futhi uqinisekisa ukusebenza okuphephile nokuthembekile kwe-transformer. Izinga lokushisa elizungezile lithinta ngqo ikhono le-transformer lokususa ukushisa nokugcina ukwenyuka kwezinga lokushisa okuzinzile ngaphakathi kwemikhawulo eyamukelekayo.

2. Ukuguga Okushisayo kanye Nemiphumela Yakho Ekusebenza Kahle Kakhulu

Izinga lokushisa linemiphumela yesikhathi eside ekusebenzeni nasekuphileni kwama-transformer. Ukuchayeka okuqhubekayo emazingeni okushisa aphezulu kusheshisa inqubo yokuguga kwe-transformer insulation nezinye izingxenye ezibalulekile. Lesi simo saziwa ngokuthi ukuguga kwe-thermal futhi singaholela ekunciphiseni ukusebenza kahle kwe-transformer ngokuhamba kwesikhathi.

a) Ukuwohloka Kwezinto Ezivikela Ukushisa

Izinto zokuvala umoya ezisetshenziswa kuma-transformer zinamandla athile okumelana nokushisa. Ukuchayeka isikhathi eside emazingeni okushisa aphezulu kungabangela ukuthi lezi zinto zonakale, kunciphise ukusebenza kwazo ekuvaleleni ugesi ekulahlekelweni kwamandla kagesi. Ngenxa yalokho, ukusebenza kahle kwe-transformer kuyancipha.

b) Ukushiswa kwe-Oxidation kwama-Windings

Ama-winding e-transformer ngokuvamile enziwa ngama-conductor ethusi noma e-aluminium. Uma evezwa emazingeni okushisa aphezulu, la ma-winding anga-oxidation, okuholela ekulahlekelweni okukhulu kokuphikisa. Ukusebenza kahle kwe-transformer kuthinteka kabi njengoba ukulahlekelwa kokuphikisa kunegalelo ekwehleni kwamandla okukhipha.

3. Umthelela Wokushisa Ekulahlekelweni Okuyinhloko

Ukulahlekelwa okuyinhloko kuyisici esibalulekile sokulahlekelwa kwe-transformer. Kuhlanganisa ukulahlekelwa kwe-hysteresis kanye nokulahlekelwa kwamanje kwe-eddy okwenzeka ngaphakathi kwe-transformer. Izinga lokushisa linobuhlobo obuqondile nalokhu kulahlekelwa, okuthonya ukusebenza kahle kwe-transformer iyonke.

a) Ukulahlekelwa yi-Hysteresis

Ukulahlekelwa yi-Hysteresis kwenzeka ngenxa yokuguqulwa kwamasimu kazibuthe ngaphakathi kwe-core ye-transformer. Lapho izinto eziyinhloko zingaphansi kwamazinga okushisa aphezulu, ukulahlekelwa yi-hysteresis kuyanda. Lokhu kuholela ekukhuleni kokulahlekelwa okuphelele kanye nokuncipha kokusebenza kahle kwe-transformer.

b) Ukulahlekelwa Kwamanje Kwe-Eddy

Ukulahlekelwa kwamandla kagesi e-Eddy kubangelwa yiziphethu ezibangelwa ukujikeleza ngaphakathi kwezinto eziyinhloko. Ukushisa okwandayo kuholela ekumelaneni okuphezulu, okuholela ekulahlekelweni kwamandla kagesi e-eddy okukhulu. Ngenxa yalokho, ukusebenza kahle kwe-transformer iyonke kwehla.

4. Ukulayisha Okungaphezu Kokujwayelekile Kwe-Transformer Nokukhuphuka Kwezinga Lokushisa

Ukusebenza kahle kwe-transformer kungathinteka kakhulu ngokugcwala ngokweqile, okubhekisela ekusebenziseni i-transformer ngaphezu kwamandla ayo alinganiselwe. Ukulayisha ngokweqile kuholela ekukhuphukeni kokugeleza kwamanje kanye nokushisa okulandelayo, okuholela emazingeni okushisa aphezulu. Lokhu kunyuka kwezinga lokushisa kuthinta kabi ukusebenza kahle kwe-transformer.

a) Izindawo Ezishisayo Nesikhathi Sokuphila Esifushane

Ngaphansi kwemithwalo esindayo, izindawo ezishisayo zendawo zingavela kuma-transformer. Lezi zindawo ezishisayo zingabangela ukuguga okusheshayo kokushisa kanye nokuwohloka kokushisa, okunciphisa kakhulu ukusebenza kahle kwe-transformer. Ngaphezu kwalokho, ukulayisha ngokweqile okuqhubekayo kungafinyeza isikhathi sokuphila kwe-transformer, kudingeke ukuthi ishintshwe ngaphambi kwesikhathi.

b) Ukulahlekelwa Okukhulu Kwethusi

Ukulayisha ngokweqile kubangela ukwanda kokugeleza kwamanje ngokusebenzisa ama-windings e-transformer, okuholela ekulahlekelweni okuphezulu kokumelana. Ukulahlekelwa yithusi kunegalelo ekwehleni kokusebenza kahle, njengoba amandla amaningi ehlakazeka njengokushisa, kunokuba adluliselwe ngempumelelo.

Isiphetho

Izinga lokushisa lidlala indima ebalulekile ekunqumeni ukusebenza kahle kwama-transformer. Izinga lokushisa elizungezile lithinta izindlela zokupholisa, imikhawulo yokunyuka kwezinga lokushisa, kanye nokusebenza kahle kwe-transformer iyonke. Ukuguga kokushisa ngenxa yokushisa okuphezulu kunciphisa ukusebenza kahle kokushisa, kuyilapho ukulahlekelwa okukhulu kwe-core kuthinta kakhulu ukusebenza kahle. Ukulayisha ngokweqile kwandisa le miphumela, okuholela ezindaweni ezishisayo, ukulahlekelwa okukhulu kwethusi, kanye nokwehluleka kwe-transformer okungenzeka. Ukuqinisekisa ukusebenza kahle kanye nokuphila isikhathi eside, kubalulekile ukugcina ama-transformer ngaphakathi kwemingcele ethile yokushisa, ukusebenzisa izinyathelo zokupholisa ezifanele, nokugwema ukulayisha ngokweqile. Ngokuqonda nokwenza ngcono izimo zokushisa, izinhlelo zikagesi zingazuza ekusebenzeni kahle kwe-transformer okuthuthukisiwe kanye nokulahlekelwa kwamandla okuncishisiwe.
