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.

Ukuhanjiswa kweTransformer yamandla ephambili kumthengi.

01 Umbane wangoku
Xa i-transformer iqala ukusebenza, kwenzeka into ebizwa ngokuba yi-magnetizing inrush. Nangona i-inrush currents ingaphazamisi njenge-fault currents, ixesha le-magnetizing inrush currents lilandelana nemizuzwana (xa kuthelekiswa namaxesha ane-fault currents).

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.

Kutheni ufunda iiTransformers?
Iitransformer zikwaziwa ngokuba ziimoto ze-AC ezingasebenziyo

I-transformer sisixhobo esingashukumiyo esisebenza rhoqo, esithembeke kakhulu xa sisebenza kwaye sinamathuba amancinci okusilela. Nangona kunjalo, ekubeni uninzi lwee-transformer zifakwe ngaphandle, kwaye zichaphazeleka ngumthwalo ngexesha lokusebenza kunye nempazamo ye-short-circuit yenkqubo yamandla, iimpazamo ezahlukeneyo kunye neemeko ezingaqhelekanga ngokungenakuphepheka ziyenzeka ngexesha lokusebenza.

1. Uhlalutyo lokusebenza okungaqhelekanga kweetransformer
(1) Isandi setransformer 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.

Ukusebenza ngokuhambelana kwee-transformers kuthetha ukuba ii-windings eziphambili zee-transformers ezimbini okanye ngaphezulu ziqhagamshelwe ngaxeshanye kwi-busbar ye-voltage efanayo, kwaye ii-windings zesibini ziqhagamshelwe ngaxeshanye kwi-busbar ye-voltage enye.






Intsingiselo yalo yile: xa itransformer enye ingaphumeleli, ezinye iitransformer ezisebenza ngaxeshanye zisenokuqhubeka nokusebenza ukuqinisekisa ukusetyenziswa kwamandla kwabasebenzisi ababalulekileyo; okanye xa itransformer kufuneka ilungiswe, itransformer emileyo inokuqhagamshelwa ngaxeshanye, ize emva koko itransformer eza kulungiswa icinywe kwaye ilungiswe. , nto leyo engenakuqinisekisa kuphela ukugcinwa okucwangcisiweyo kwetransformer, kodwa ikwaqinisekisa ukuba umbane awuphazanyiswa kwaye iphucule ukuthembeka kombane.

Kukho izizathu ezibini eziphambili zokuvuza kweoyile yetransformer: kwelinye icala, iingxaki ezishiyekileyo kwinkqubo yoyilo lwetransformer kunye nenkqubo yokwenziwa kwayo; Kwelinye icala, ukuvuza kubangelwa kukufakelwa nokugcinwa kwayo ngendlela engafanelekanga. Iindawo eziphambili zokuvuza zetransformer zihlala zivela kwindawo yokujonga iradiator, isiciko sevalvu yebhabhathane esithe tyaba, isingxobo, ibhotile yeporcelain, i-weld, umngxuma wesanti, iflange kunye nezinye iindawo.
