Uvavanyo olungenamthwalo we-transformer luvavanyo lokulinganisa ilahleko yokungabikho komthwalo kunye nokungabikho komthwalo wangoku we-transformer ngokusebenzisa i-voltage elinganisiweyo ye-sine wave elinganiswe ngokuphindaphindiweyo ukusuka ekujikeni macala omabini e-transformer, kunye amanye amajiko-jiko avulekileyo.Umsinga wokungathwali mthwalo uchazwa njengepesenti yomlinganiso wokungabikho komthwalo wangoku i-I0 ukuya kumlinganiselo wangoku okt, ochazwa njenge-IO.
I-HV HIPOT GDBR uthotho lwesiguquli umthamo kunye nomvavanyi ongenamthwalo
Xa kukho umehluko omkhulu phakathi kwexabiso elilinganiswe ngovavanyo kunye nexabiso lokubala loyilo, ixabiso lefektri, ixabiso lohlobo olufanayo lwe-transformer okanye ixabiso ngaphambi kokuguqulwa, isizathu kufuneka sifumaneke.
Ilahleko engenamthwalo ubukhulu becala ilahleko yentsimbi, oko kukuthi, ukulahleka kwe-hysteresis kunye nelahleko yangoku ye-eddy esetyenzisiweyo kwintsimbi yentsimbi.Xa kungekho mthwalo, i-excitation current equkuqela kwi-primary winding iphinda ivelise ilahleko yokuxhathisa, enokungahoywa ukuba i-excitation current incinci.Ukulahlekelwa komthwalo kunye nokungabikho komthwalo okwangoku kuxhomekeke kwizinto ezifana nomthamo we-transformer, isakhiwo se-core, ukuveliswa kwe-silicon sheet sheet kunye nenkqubo yokuvelisa ingundoqo.
Izizathu eziphambili zokunyuka kokulahlekelwa ngumthwalo kunye nokungabikho komthwalo wangoku: ukufakwa okungahambi kakuhle phakathi kwamaphepha ensimbi ye-silicon;isiphaluka esifutshane senxalenye ethile yamaphepha ensimbi ye-silicon;i-short-circuit turns eyenziwe ngumonakalo kwi-insulation of core bolts okanye iiplate zoxinzelelo, iidyokhwe eziphezulu kunye nezinye iindawo;I-silicon sheet sheet ikhululekile, kwaye i-gap yomoya ibonakala, eyandisa ukuchasana kwamagnetic (ikakhulukazi kwandisa i-no-load current);indlela yamagnetic yenziwe ngeshiti yensimbi ye-silicon engqindilili (akukho mthwalo wokulahleka ukwanda kwaye akukho mthwalo uyancipha ngoku);insimbi ye-silicon engaphantsi isetyenziswa Iziqwenga (zixhaphake kakhulu kwii-transformers ezincinci zokusabalalisa);iziphene ezahlukeneyo zokujija, kubandakanya i-inter-turn short circuit, i-parallel yesebe yesekethe emfutshane, inani elahlukileyo lokujika kwisebe ngalinye elihambelanayo, kunye nokufunyanwa kwe-ampere-turn engalunganga.Ukongezelela, ngenxa yokungahambi kakuhle kwesiphaluka samagnetic, njl., akukho mthwalo wokulahlekelwa kunye nokunyuka kwangoku kuya kubangelwa.Kwi-transformers encinci kunye ne-medium-size, ubungakanani be-core seam bunokuchaphazela kakhulu ukungabikho komthwalo wangoku ngexesha lenkqubo yokuvelisa.
Xa usenza uvavanyo olungenamthwalo we-transformer, ukwenzela ukuba kube lula ukukhethwa kwezixhobo kunye nezixhobo kunye nokuqinisekisa ukhuseleko lovavanyo, isixhobo kunye nonikezelo lwamandla ludibene ngokubanzi kwicala le-low-voltage, kunye ne-high-voltage side. ishiywe ivuliwe.
Uvavanyo olungenamthwalo kukulinganisa ilahleko yomthwalo kunye nokungabikho komthwalo wangoku phantsi kwe-voltage elinganisiweyo.Ngethuba lovavanyo, i-high-voltage side ivulekile, kwaye i-low-voltage side ixinzezelekile.I-voltage yovavanyo yi-voltage elinganisiweyo yecala le-low-voltage.I-voltage yokuvavanya iphantsi, kwaye uvavanyo lwangoku luyipesenti ezimbalwa zangoku ezilinganisiweyo.okanye amawaka.
I-voltage yovavanyo yovavanyo lwe-no-load ye-voltage elinganisiweyo yecala eliphantsi-voltage, kwaye uvavanyo olungenamthwalo lwe-transformer lulinganisa ukulahlekelwa komthwalo.Iilahleko ezingathwaliyo umthwalo ikakhulu ziilahleko zentsimbi.Ubungakanani belahleko yentsimbi bunokuthathwa njengento ezimeleyo kubukhulu bomthwalo, oko kukuthi, ukulahlekelwa kwi-no-load ilingana nokulahlekelwa kwentsimbi kumthwalo, kodwa oku kubhekisela kwimeko kwi-voltage elinganisiweyo.Ukuba i-voltage iyaphambuka kwixabiso elilinganisiweyo, ekubeni ukungeniswa kwamagnetic kwi-transformer core kwicandelo lokuzalisa i-curve ye-magnetization, ukulahlekelwa komthwalo kunye nokungabikho komthwalo kuya kutshintsha ngokukhawuleza.Ngoko ke, uvavanyo olungenamthwalo kufuneka lwenziwe kwi-voltage elinganisiweyo.
