Ukutyhila Ihlabathi Labaguquli Be-20000 kVA

Intshayelelo:

Iitransformer ziyinxalenye ebalulekileyo yehlabathi lethu lanamhlanje, zidlala indima ebalulekileyo ekudluliseni nasekusasazeni amandla ombane ngokufanelekileyo. Phakathi kweetransformer ezininzi, uhlobo oluthile olubalaseleyo ngomthamo walo omkhulu yitransformer ye-20000 kVA. Ngomlinganiselo wamandla okwaziyo ukusingatha imithwalo emikhulu, ezi transformer zisetyenziswa kakhulu kwizicelo ezinkulu zoshishino nakwezorhwebo. Kweli nqaku, siza kujonga kwihlabathi leetransformer ze-20000 kVA, sihlola ukwakhiwa kwazo, ukusebenza kwazo, ukusetyenziswa kwazo kunye neenzuzo zazo.

I-Anatomy ye-20000 kVA Transformer

I-transformer ye-20000 kVA, eyaziwa ngokuba yi-transformer ye-20 MVA, sisixhobo esinomthamo ophezulu esenzelwe ukuphatha amandla amakhulu ombane. Igama elithi 20000 kVA libhekisa kumlinganiselo wamandla abonakalayo we-transformer, ebonisa amandla ayo okuphatha amandla okwenyani (alinganiswa ngee-watts) kunye namandla asebenzayo (alinganiswa nge-volt-amperes-reactive, okanye i-VAR). Ezi transformers zihlala zisebenza kumanqanaba aphezulu ombane, ngokuqhelekileyo phakathi kwe-11kV kunye ne-33kV, kwaye zehlise i-voltage ukuya kumanqanaba alawulekayo ukuze isetyenziswe.

Ngaphakathi kwi-transformer ye-20000 kVA, umbindi usebenza njengecandelo layo eliphambili, okwenza kube lula ukuguqulwa kwamandla ombane. Umbindi uhlala wakhiwe kusetyenziswa amaphepha e-silicon steel aqinisiweyo, abekwe ngononophelo ukunciphisa ilahleko zamandla e-eddy. Ukongeza, umbindi wenziwa ube yisakhiwo esivaliweyo ukuze kuphuculwe amandla emagnethi aveliswa ngexesha lokusebenza. Olu yilo lombindi luphucula ukusebenza kakuhle kwe-transformer ngokunciphisa ilahleko zamandla kunye nokuveliswa kobushushu.

Zijikeleze umbindi, ii-windings eziphambili nezesibini zibotshelelwa ngononophelo. Ezi windings ziquka ukujika okuphindaphindiweyo kobhedu okanye i-aluminium conductor, ezigqunyiweyo ukuthintela ii-short circuits. I-windings yokuqala iqhagamshelwe kwicala le-voltage ephezulu yegridi yombane, ngelixa i-winding yesibini iqhagamshelwe kwicala le-voltage ephantsi, inika amandla kubasebenzisi bokugqibela.

Ukufakwa kobushushu phakathi kwee-windings kunye nombindi kudlala indima ebalulekileyo ekuthinteleni ukonakala kombane nokuqinisekisa ukusebenza ngokukhuselekileyo. Izixhobo ezahlukeneyo zokufakelwa kobushushu, ezifana neemveliso ezisekwe kwi-cellulose okanye iinkqubo zokufakelwa kobushushu ezizaliswe yioyile, zisetyenziswa ngokusekelwe kuyilo oluthile kunye neemfuno ze-transformer. Ezi nkqubo zokufakelwa kobushushu zivavanywa ngokungqongqo ukuqinisekisa ukusebenza okuthembekileyo kunye nobude bexesha.
