Ukuqonda Ububanzi Bokushisa Bokuguqula I-Transformer

Isingeniso

Ama-transformer ayizingxenye ezibalulekile ezisetshenziswa ezinhlelweni zamandla kagesi ukuze kudluliselwe kahle i-voltage. Adlala indima ebalulekile ekudluliseni ugesi usuka eziteshini zamandla uye emakhaya ethu, emahhovisi nasezimbonini. Kodwa-ke, ama-transformer akhiqiza ukushisa ngesikhathi sokusebenza, ikakhulukazi ngenxa yokulahlekelwa ugesi kanye nogesi okwenzeka ngaphakathi kwama-windings awo. Ukuqonda izinga lokushisa lapho ama-transformer windings esebenza khona kubalulekile ukuqinisekisa ukusebenza kwawo, ukuphepha, kanye nokuphila isikhathi eside. Lesi sihloko sigxila ezinkingeni zezinga lokushisa lama-transformer winding, sixoxa ngokubaluleka kwalo, izici ezithinta lona, ​​amasu okulinganisa, kanye nezinyathelo zokuqapha ezidingekayo.

I. Ukubaluleka Kobubanzi Bokushisa Bokuguqula I-Transformer

Ukusebenza kahle kwama-transformer kuncike ngqo ekugcineni amazinga okushisa afanele ngaphakathi kwemingcele echaziwe. Ukusebenzisa i-transformer ngaphandle kwebanga layo lokushisa elifanele kungaholela ezinkingeni eziningana, okuhlanganisa ukusebenza kahle okuncishisiwe, isikhathi sokuphila esifushane, ngisho nokwehluleka okukhulu. Ngakho-ke, kubalulekile ukuqonda ukubaluleka kwebanga lokushisa elijikelezayo nokuthi lithinta kanjani ukusebenza kwe-transformer iyonke.

II. Izici Ezithonya Ububanzi Bokushisa Okuguqukayo Kwe-Transformer

Izici eziningana zingathonya ububanzi bokushisa lapho i-transformer winding isebenza khona. Lezi zici zidinga ukuhlolwa ngokucophelela nokuphathwa ukuqinisekisa ukuthi i-transformer isebenza kahle, ngaphandle kokubeka engcupheni ubude bayo. Ake sihlole ezinye zezici ezibalulekile ezithinta ububanzi bokushisa be-winding:

a. Umthwalo Wamanje

Esinye sezici eziyinhloko ezinquma izinga lokushisa lokugoqa i-transformer yi-load current. Ama-transformer aklanyelwe ukusebenza ngaphakathi kwemingcele ethile yomthwalo. Ukulayisha ngokweqile i-transformer kungabangela ukukhiqizwa kokushisa okweqile kuma-windings, okuholela ekugugeni okusheshayo kanye nokuwohloka kokushisa. Ngakho-ke, ama-transformer kufanele asebenze ngaphakathi kwemingcele yawo yomthwalo olinganiselwe ukuze alondoloze amazinga okushisa afanele okugoqa.

b. Izinga Lokushisa Eliphakathi

Izinga lokushisa elizungeze i-transformer lithinta nezinga lokushisa elijikelezayo.
