Zithini iiTransformer Taps

Iimpompo zetransformer ziindawo zonxibelelwano ecaleni kwetransformer winding ezivumela ukulungiswa komlinganiselo wokujika, ngaloo ndlela kuvumela ulawulo lwevoltage. Ngokutshintsha inani leeturns kwi-winding, i-output voltage yetransformer inokwandiswa okanye incitshiswe ukugcina inqanaba elifunekayo, oku kuhlawula utshintsho kwi-input voltage okanye iimeko zomthwalo.

Indlela iiTransformer Taps ezisebenza ngayo

I-transformer inee-windings ezimbini okanye ngaphezulu—eziphambili nezesibini—ezijikeleze i-magnetic core. Umlinganiselo wokujika phakathi kwezi windings umisela utshintsho lwe-voltage. Ii-transformer taps zibekwe ngobuchule ecaleni kwee-windings, zibonelela ngokufikelela kwiinani ezahlukeneyo zee-turns.

Xa kukhethwe itephu, itshintsha ngokufanelekileyo inani leenguqu ezisebenzayo kwi-winding, itshintsha umlinganiselo we-turns kwaye, ngenxa yoko, i-output voltage. Umzekelo, ukuba itephu ye-transformer imiselwe ukuba ibandakanye iinguqu ezininzi, i-output voltage iya kwanda, ngelixa ukukhetha itephu ene-turns ezimbalwa kuya kunciphisa i-output voltage.
