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.

Ukulethwa kwe-Main Power Transformer kumakhasimende.

Noma yisiphi isicelo, mayelana nama-transformer, sicela uxhumane nommeleli wethu wokuthengisa.

Lesi sihloko sibala kakhulu izinhlobo ezi-7 zezindlela zokwahlulela amaphutha kanye nokuhlaziywa kwesixazululo somsindo we-transformer wohlobo olomile. Uma kukhona iphutha noma ukushiywa, sicela ukukhombe endaweni yokuphawula.
Ukuhlaziywa kwezinhlobo ezi-7 zezindlela zokwahlulela amaphutha kanye nezixazululo zomsindo we-transformer wohlobo olomile
➢Izinkinga zomsindo wamafeni, ama-casing nezinye izingxenye
➢Izinkinga zokufakwa
➢ Ithonya lendawo yokufaka
➢Inkinga yokudlidliza kwebhuloho lebhasi
➢I-transformer core iyazivuselela ngokwayo.
➢I-Transformer coil self-resonance
➢Inkinga yohlobo lomthwalo

Amadivayisi okuvikela ahambisanayo kufanele afakwe amaphutha okujikeleza okufushane kwezintambo ze-lead ze-transformer, ama-bushing kanye nezinto zangaphakathi, futhi kufanele ahlangabezane nezidingo ezilandelayo:
1) I-transformer esebenza kanye ye-10MVA nangaphezulu kanye ne-transformer esebenza ngokufanayo ye-6.3MVA nangaphezulu kufanele ifakwe isivikelo sokwehluka kwe-longitudinal. Ama-transformer abalulekile ane-6.3MVA nangaphansi asebenza ngokuzimela nawo angafakwa isivikelo sokwehluka kwe-longitudinal.
2) Ama-transformer angaphansi kwe-10MVA angafakelwa isivikelo sokuphuka okusheshayo kwamanje kanye nesivikelo sokukhuphuka komoya. Kuma-transformer e-2MVA nangaphezulu, lapho i-coefficient yokuzwela ukuphuka okusheshayo kwamanje ingahlangabezani nezidingo, kufanele kufakwe isivikelo sokwehluka kwe-longitudinal.
3) 0.4MVA nangaphezulu, i-voltage eyinhloko ingu-10kV nangaphansi, kanti ikhoyili iyi-transformer enoxhumano lwe-delta-star, futhi isivikelo sokushintshashintsha komoya esinohlobo lwe-relay ezintathu esingasetshenziswa.
4) Amadivayisi ahlukahlukene okuvikela achazwe kulesi sihloko azosebenza ukuze anqamule ama-circuit breaker ohlangothini ngalunye lwe-transformer.

01 I-Inrush yamanje
Uma i-transformer iqala ukunikezwa amandla, kwenzeka into ebizwa ngokuthi i-magnetizing inrush. Nakuba ama-inrush currents ngokuvamile engaphazamisi njenge-fault currents, isikhathi sama-magnetizing inrush currents silandelana ngemizuzwana (uma kuqhathaniswa nezikhathi ezine-fault currents).

Ukuhlolwa kokungathwali umthwalo: Sebenzisa i-voltage elinganisiwe yemvamisa elinganisiwe ye-sine wave kusuka ekugoqeni okuthile kwe-transformer (ngokuvamile kusuka ohlangothini lwesibili lwe-voltage ephansi), bese uvula amanye ama-windings ukuze ulinganise ukulahleka kwamandla okungenamthwalo kanye nokulahlekelwa umthwalo. Uma izimo zokuhlola zilinganiselwe futhi i-voltage yokunikezwa kwamandla ingakwazi ukufinyelela i-voltage elinganisiwe, ukuhlolwa kungenziwa ngaphansi kwezimo ze-voltage ezingalinganisiwe. Le ndlela yokuhlola inephutha elikhulu futhi ngokuvamile isetshenziselwa kuphela ukuhlola ukuthi i-transformer inephutha. I-voltage yokuhlola kuphela efinyelela ngaphezu kuka-80% we-voltage elinganisiwe.

Ama-transformer acwiliswe ku-oyela anezimpawu zokushabalalisa ukushisa okuhle, ukulahleka okuphansi, amandla amakhulu kanye nentengo ephansi. Njengamanje, iningi lama-transformer kagesi asebenza kugridi angama-transformer acwiliswe ku-oyela, lapho angaphezu kuka-80% apholiswa khona ukujikeleziswa kuka-oyela kwemvelo. Yisakhiwo sokupholisa esivame ukusetshenziswa ukusetha ipuleti eliqondisayo kukhoyili ye-transformer yokujikeleziswa kuka-oyela yemvelo. Leli phepha ligxile ekuhlaziyeni isakhiwo, ukusebenza kanye nokugcinwa kwama-transformer kagesi acwiliswe ku-oyela, futhi lihlaziya ngokukhethekile uhlelo luka-oyela lwama-transformer kagesi acwiliswe ku-oyela, futhi lihlaziya kafushane amaphutha ama-transformer kagesi acwiliswe ku-oyela. Ngiyethemba ukwandisa ukuqonda kanye nokuhlaziywa kwama-transformer kagesi acwiliswe ku-oyela ezweni lami.

Isingeniso
i-transformer
Idivayisi eshintsha i-voltage, i-current, noma isigaba ngokuhlanganisa isekethe yamagnetic
Kungani ufunda ama-Transformers?
Ama-Transformer aziwa nangokuthi ama-motor e-AC amile

Le vidiyo ikubonise ukuthi i-power transformer eyinhloko ibukeka kanjani.

I-transformer iyithuluzi elingaguquki elisebenza njalo, elithembekile uma lisebenza futhi linamathuba amancane okwehluleka. Kodwa-ke, njengoba iningi lama-transformer lifakwe ngaphandle, futhi lithintwa umthwalo ngesikhathi sokusebenza kanye nephutha le-short-circuit yesistimu yamandla, amaphutha ahlukahlukene kanye nezimo ezingavamile zenzeka ngokungenakugwenywa ngesikhathi sokusebenza.

Uhlelo lokupholisa lwe-transformer yamandla luqukethe izingxenye ezimbili: uhlelo lokupholisa lwangaphakathi, oluqinisekisa ukuthi ukushisa kwe-winding kanye ne-iron core kuhlakazeka endaweni ezungezile; uhlelo lokupholisa lwangaphandle, oluqinisekisa ukuthi ukushisa okuphakathi kuhlakazeka ngaphandle kwe-transformer. Ngokusho kobukhulu bomthamo we-transformer, indawo kanye nohlobo lokujikeleza, i-transformer isebenzisa izindlela ezahlukene zokupholisa.
