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.

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.

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.

(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).

Izinto eziyinhloko zomzimba we-transformer zifaka izinto zesekethe ezisebenza ngogesi, izinto zesekethe, izinto zokuvikela umswakama, izinto zokwakha, njll.

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.
