Isigaba sesi-3 – Uyiqonda kanjani incazelo “yesiguquli esihlukanisayo sokuphepha”
i-transformer yokuphepha ehlukanisayo: i-transformer, okokufaka okujikajikayo okuhlukaniswa ngogesi kusukela ekujikeni kokuphumayo ngesimbobo okungenani esilingana nokufakwa okuphindwe kabili noma ukwahlukanisa okuqinisiwe, okuhloselwe ukunikeza into esetshenziswayo noma isekethe ku-voltage ephephile ephansi kakhulu
I-transformer okukhulunywe ngayo lapha isetshenziselwa ukuhlinzeka ngamandla ezintweni ezisetshenziswayo noma kumasekhethi. Ama-transformer amaningi ajwayelekile ahlinzeka ngamandla kumasekhethi, futhi ambalwa anikezela ngamandla ezintweni zikagesi. Okubalulekile lapha izilinganiso zokuhlukanisa zokufaka okokufaka kanye nokujikajika kokuphumayo, okudingeka kube ukufakwa okuphindwe kabili noma uhlobo lokufakwa okuqinisiwe, noma uhlobo olulinganayo lokugquma. Le mfuneko iwukuqinisekisa ukuthi ama-winging ayisisekelo kanye namajika esibili ane-insulation eyanele. Uma ukufakwa kwe-insulation kwanele, ukuhlukaniswa phakathi kwama-windings ayisisekelo nakwesibili we-transformer kuphephile. Izinyathelo zokuvikela kabili.
Ama-transformer amabili asetshenziswa kakhulu ezintweni zasendlini akhonjisiwe esithombeni esingezansi.
Uhlobo lokuqala lwesiguquli esisetshenziswa ekushintsheni kwamandla e-PCBboard. Lolu hlobo lwe-transformer luzobeka phezulu ama-windings ayisisekelo nawesibili kumongo ofanayo kazibuthe. Ngakho-ke, ukuze kuqinisekiswe ibanga le-creepage kanye nokuvunyelwa kukagesi phakathi kwesisekelo sokuqala nesesibili, ama-windings amanxeba angeke abekwe ebusweni bokugcina obuphezulu naphansi. Ama-windings adinga ukuba ebangeni elithile ukusuka ebusweni obuphezulu naphansi, njengoba kukhonjisiwe esithombeni esingezansi:
Ukuze usize abafundi baqonde kangcono ukwakheka kwale transformer, ngibeke izithombe zengaphandle nengaphakathi layo yonke i-transformer kuleli khasi ukuze kusetshenziswe ireferensi yabafundi.

umsekeli wangaphakathi wokuphepha ohlukanisa i-transformer
Enye iwuhlobo lwe-drawer-linear transformer, njengoba kukhonjisiwe ngezansi:
