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.

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.

I-grounding transformer ibizwa ngokuthi i-grounding transformer ngamafuphi. Ngokusho kwe-filling medium, i-grounding transformer ingahlukaniswa ngohlobo lwamafutha nohlobo olomile; Ngokusho kwenani lezigaba, i-grounding transformer ingahlukaniswa ibe yi-grounding transformer yesigaba esithathu kanye ne-grounding transformer yesigaba esisodwa. Umsebenzi we-grounding transformer ukuhlinzeka ngephuzu elingathathi hlangothi lokwenziwa lesistimu elinephuzu elingathathi hlangothi elingaguquki, elilungele ukusetshenziswa kwe-arc suppression coil noma imodi encane yokuguquguqula ukumelana, ukuze kuncishiswe amandla kagesi emhlabathini uma kwenzeka iphutha le-grounding short circuit kunethiwekhi yokusabalalisa futhi kuthuthukiswe ukuthembeka kokunikezwa kwamandla ohlelweni lokusabalalisa.

Ukuhlaziywa kokusebenza okungajwayelekile kwama-transformer
Umsindo we-transformer awujwayelekile


Lapho nje i-transformer isixhunywe kugesi, kuzoba nomsindo ovunguzayo, obangelwa kakhulu umphumela we-magnetic flux enamandla aphezulu. Ngesikhathi sokusebenza okuvamile, umsindo we-transformer uyalingana. Uma kuneminye imisindo, kufanele uthole imbangela ngokucophelela bese ubhekana nayo.
