1. What does △/Y0-11 mean on the transformer nameplate?
Answer: According to the different connection methods of the primary coil and the secondary coil of the transformer, the phase angle of the line voltage on the primary side and the secondary side of the transformer is different. Transformer △/ Y0-11 means that the phase angle difference between the two line voltages of the transformer is 330°. It is customary to use the clock notation, that is, 11 o'clock.

01 Umbane wangoku
Xa i-transformer iqala ukusebenza, kwenzeka into ebizwa ngokuba yi-magnetizing inrush. Nangona i-inrush currents ingaphazamisi njenge-fault currents, ixesha le-magnetizing inrush currents lilandelana nemizuzwana (xa kuthelekiswa namaxesha ane-fault currents).

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.

Iitransformer ezintywilisiweyo kwioyile zineempawu zokusasaza ubushushu kakuhle, ukulahleka okuphantsi, amandla amakhulu kunye nexabiso eliphantsi. Okwangoku, uninzi lweetransformer zamandla ezisebenza kwigridi ziitransformer ezintywilisiweyo kwioyile, apho ngaphezulu kwama-80% azo zipholiswa kukujikeleza kweoyile yendalo. Sisakhiwo sokupholisa esisetyenziswa rhoqo ukuseta ipleyiti yesikhokelo kwikhoyili yetransformer yokujikeleza kweoyile yendalo. Eli phepha ligxile ekuhlalutyeni ulwakhiwo, ukusebenza kunye nokugcinwa kweetransformer zamandla ezintywilisiweyo kwioyile, kwaye ngokukodwa lihlalutya inkqubo yeoyile yeetransformer zamandla ezintywilisiweyo kwioyile, kwaye lihlalutya ngokufutshane iimpazamo zeetransformer zamandla ezintywilisiweyo kwioyile. Ndinethemba lokwandisa ukuqonda kunye nohlalutyo lweetransformer zamandla ezintywilisiweyo kwioyile zelizwe lam.

Kutheni ufunda iiTransformers?
Iitransformer zikwaziwa ngokuba ziimoto ze-AC ezingasebenziyo

Le vidiyo ikubonise ukuba injani i-power transformer ephambili.

I-transformer sisixhobo esingashukumiyo esisebenza rhoqo, esithembeke kakhulu xa sisebenza kwaye sinamathuba amancinci okusilela. Nangona kunjalo, ekubeni uninzi lwee-transformer zifakwe ngaphandle, kwaye zichaphazeleka ngumthwalo ngexesha lokusebenza kunye nempazamo ye-short-circuit yenkqubo yamandla, iimpazamo ezahlukeneyo kunye neemeko ezingaqhelekanga ngokungenakuphepheka ziyenzeka ngexesha lokusebenza.

Inkqubo yokupholisa ye-power transformer inamacandelo amabini: inkqubo yokupholisa yangaphakathi, eqinisekisa ukuba ubushushu bokujika kunye nombindi wentsimbi buyasasazeka kwindawo ejikelezileyo; inkqubo yokupholisa yangaphandle, eqinisekisa ukuba ubushushu obukwindawo busasazeka ngaphandle kwe-transformer. Ngokobukhulu bomthamo we-transformer, indawo kunye nohlobo lokujikeleza, i-transformer isebenzisa iindlela ezahlukeneyo zokupholisa.

Xa i-transformer core ibekwe ndawonye, ​​zeziphi iindlela zomthungo? Zithini iimpawu zayo nganye nganye? Eli nqaku liqala kwisayensi edumileyo yee-iron cores, kwaye liyakhula kwaye likwandise ukujonga indlela yomthungo yeeshiti zesinyithi ze-silicon xa ii-transformer iron cores zibekwe ndawonye.
