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.

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

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.

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.

1. Ukuhlaziywa kokusebenza okungajwayelekile kwama-transformer
(1) 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.

Ku-AC circuit, kunemibono emithathu yamandla kagesi: amandla asebenzayo, amandla asebenzayo kanye namandla abonakalayo. I-KVA imele amandla abonakalayo, okuhlanganisa amandla asebenzayo kanye namandla asebenzayo. I-KW imele amandla asebenzayo, kanti i-kVar imele amandla asebenzayo. Ubudlelwano phakathi kwe-kW ne-kVar kanye nokuguqulwa lapho kunomqondo - i-power factor cos ф, amandla asebenzayo kW=UIcos ф, amandla asebenzayo kVar=UIsin ф, kanye namandla abonakalayo kVA=UI(U yi-voltage, u-I ungumshini wamanje).

Isakhiwo somzimba we-transformer
Leli phepha liveza kakhulu isakhiwo somzimba we-transformer ngezici ezintathu: umongo, ukugoqa kanye nomthofu.
I. Isakhiwo se-Transformer core
01 Indima yensimbi ye-silicon (Insimbi) eyinhloko
Ama-Transformer asekelwe esimisweni sokungeniswa kwe-electromagnetic, isekethe yamagnetic iyindlela yokuguqulwa kwamandla kagesi. I-Iron core iyisekethe yamagnetic eyinhloko ye-transformer, indima eyinhloko i-magnetic. Iguqula amandla kagesi esekethe eyinhloko abe amandla kazibuthe, futhi kusukela emandleni kazibuthe abe amandla kagesi esekethe yesibili.
Ngesikhathi esifanayo, i-iron core iyi-mechanical skeleton ye-transformer, futhi idivayisi yokubamba ye-iron core ayenzi nje kuphela i-magnetic conductor ibe yisakhiwo esiphelele se-mechanical, kodwa futhi ine-coil evikelwe yi-insulated kuyo, esekela i-lead, kanye nazo zonke izingxenye ezingaphakathi kwe-transformer. Isisindo se-iron core sikhulu kunazo zonke ezingxenyeni ze-transformer, esibalelwa cishe ku-60% wesisindo esiphelele ku-transformer eyomile, kanye no-40% ku-transformer ecwiliswe ngamafutha.
