Uvavanyo lokungathwali mthwalo: Sebenzisa i-voltage elinganisiweyo ye-sine wave rated frequency ukusuka kwindawo ethile yokujikajika ye-transformer (ngokubanzi ukusuka kwicala lesibini le-voltage ephantsi), kwaye uvule ezinye ii-windings ukuze ulinganise ilahleko yangoku engenamthwalo kunye nelahleko engenamthwalo. Ukuba iimeko zovavanyo zinqongophele kwaye i-voltage yombane ayinakufikelela kwi-voltage elinganisiweyo, uvavanyo lunokwenziwa phantsi kweemeko ze-voltage ezingalinganiyo. Le ndlela yovavanyo inempazamo enkulu kwaye ngokubanzi isetyenziselwa ukujonga ukuba i-transformer inempazamo na. Yi-voltage yovavanyo kuphela efikelela ngaphezulu kwe-80% ye-voltage elinganisiweyo. Enokusetyenziselwa ukuvavanya ilahleko engenamthwalo.

Iqhutywa bubuchule besayensi nobuchwepheshe, iKeying Electric ikhokela intsimi yombane oguqulayo ukuya kwindawo enzulu yamanzi enomgangatho ophezulu, ekrelekrele nevelisa izinto ezinkulu.

Ulwakhiwo lomzimba we-transformer
Eli phepha lichaza ikakhulu ulwakhiwo lomzimba we-transformer kwiinkalo ezintathu: umbindi, ukujija kunye ne-lead.
I. Ulwakhiwo oluphambili lweTransformer
01 Indima yesiseko sesinyithi sesilicon (Iron)
Iitransformer zisekelwe kumgaqo wokungeniswa kwe-electromagnetic, isekethe yemagnethi yindlela yokuguqula amandla ombane. I-iron core yisekethe yemagnethi ephambili yetransformer, indima ephambili yimagnethi. Iguqula amandla ombane esekethe ephambili abe ngamandla emagnethi, kwaye ukusuka kumandla emagnethi abe ngamandla ombane esekethe yesibini.
Kwangaxeshanye, umbindi wentsimbi ngumzimba womatshini wetransformer, kwaye isixhobo sokubambelela sombindi wentsimbi asenzeli nje kuphela umqhubi wemagnethi ukuba abe yisakhiwo esipheleleyo somatshini, kodwa sikwanayo nekhoyili egqunyiweyo kuyo, exhasa ilothe, kunye nazo zonke izinto ezingaphakathi kwetransformer. Ubunzima bombindi wentsimbi bubona bukhulu kwiindawo zetransformer, bumalunga nama-60% obunzima bubonke kwitransformer eyomileyo, kwaye malunga nama-40% kwitransformer entywilisiweyo kwioyile.
