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.

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.

Intshayelelo
isiguquli
Isixhobo esitshintsha i-voltage, i-current, okanye i-phase ngokudibanisa isekethe yemagnethi
Kutheni ufunda iiTransformers?
Iitransformer zikwaziwa ngokuba ziimoto ze-AC ezingasebenziyo

Le vidiyo ikubonise ukuba injani i-power transformer ephambili.

Uhlalutyo lokusebenza okungaqhelekanga kweetransformer
Isandi se-transformer asiqhelekanga


Kwakamsinya nje ukuba i-transformer iqhagamshelwe kumbane, kuya kubakho isandi esirhabaxa, esibangelwa ikakhulu yimpembelelo ye-magnetic flux enamandla aphezulu. Ngexesha lokusebenza okuqhelekileyo, isandi se-transformer siyafana. Xa kukho ezinye iingxolo, kufuneka ufumane unobangela ngononophelo kwaye ujongane nawo.

Kwakamsinya nje ukuba i-transformer iqhagamshelwe kumbane, kuya kubakho isandi esirhabaxa, esibangelwa ikakhulu yimpembelelo ye-magnetic flux enamandla aphezulu. Ngexesha lokusebenza okuqhelekileyo, isandi se-transformer siyafana. Xa kukho ezinye iingxolo, kufuneka ufumane unobangela ngononophelo kwaye ujongane nawo.

Kwisekethe ye-AC, kukho iingcamango ezintathu zamandla ombane: amandla asebenzayo, amandla asebenzayo kunye namandla abonakalayo. I-KVA imele amandla abonakalayo, aquka amandla asebenzayo kunye namandla asebenzayo. I-KW imele amandla asebenzayo, kwaye i-kVar imele amandla asebenzayo. Ubudlelwane phakathi kwe-kW kunye ne-kVar kunye nokuguqulwa apho kukho ingcamango - amandla e-cos ф, amandla asebenzayo kW=UIcos ф, amandla asebenzayo kVar=UIsin ф, kunye namandla abonakalayo kVA=UI(U yi-voltage, u-I ngumbane).

Izinto eziphambili zomzimba we-transformer ziquka izixhobo zesekethe zemagnethi, izixhobo zesekethe, izinto zokukhusela ubushushu, izixhobo zokwakha, njl.

Ulwakhiwo lomzimba we-transformer
Eli phepha lichaza ikakhulu ulwakhiwo lomzimba we-transformer kwiinkalo ezintathu: umbindi, ukujija kunye ne-lead.
I. Ulwakhiwo oluphambili lweTransformer
01 Indima yesiseko sesinyithi sesilicon (Iron)
Iitransformer zisekelwe kumgaqo wokungeniswa kwe-electromagnetic, isekethe yemagnethi yindlela yokuguqula amandla ombane. I-iron core yisekethe yemagnethi ephambili yetransformer, indima ephambili yimagnethi. Iguqula amandla ombane esekethe ephambili abe ngamandla emagnethi, kwaye ukusuka kumandla emagnethi abe ngamandla ombane esekethe yesibini.
Kwangaxeshanye, umbindi wentsimbi ngumzimba womatshini wetransformer, kwaye isixhobo sokubambelela sombindi wentsimbi asenzeli nje kuphela umqhubi wemagnethi ukuba abe yisakhiwo esipheleleyo somatshini, kodwa sikwanayo nekhoyili egqunyiweyo kuyo, exhasa ilothe, kunye nazo zonke izinto ezingaphakathi kwetransformer. Ubunzima bombindi wentsimbi bubona bukhulu kwiindawo zetransformer, bumalunga nama-60% obunzima bubonke kwitransformer eyomileyo, kwaye malunga nama-40% kwitransformer entywilisiweyo kwioyile.
