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).

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.

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.

I-grounding transformer ibizwa ngokuba yi-grounding transformer ngamafutshane. Ngokwe-filling medium, i-grounding transformer inokwahlulwa ibe yi-oyile kunye ne-dry type; Ngokwenani lezigaba, i-grounding transformer inokwahlulwa ibe yi-grounding transformer yesigaba esithathu kunye ne-grounding transformer yesigaba esinye. Umsebenzi we-grounding transformer kukubonelela ngendawo engathathi hlangothi yokwenziwa kwenkqubo ene-underground neutral point, elungele ukusetyenziswa kwe-arc compression coil okanye i-grounding mode encinci yokumelana, ukuze kuncitshiswe i-capacitance current ukuya emhlabeni xa kuthe kwafakwa i-ground short circuit fail kwinethiwekhi yokusasaza kwaye kuphuculwe ukuthembeka kokunikezelwa kwamandla kwenkqubo yokusasaza.

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.

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.

Ukhuseleko lwegesi lolona khuselo luphambili kwiimpazamo zangaphakathi zetransformer. Ingasebenza ngononophelo kwiisekethe ezimfutshane zetransformer eziphakathi kunye neze-inter-layer, iimpazamo zentsimbi, iimpazamo ze-bushing zangaphakathi, ukunqanyulwa kwe-insulation yangaphakathi, ukonakala kwe-insulation kunye nokuwa kwenqanaba leoyile. Xa kukho impazamo ngaphakathi kwetransformer entywilisiweyo kwioyile, i-arc iya kubolisa izinto zokukhusela kwaye ivelise inani elikhulu legesi, eliphuma kwitanki yeoyile ukuya kumqamelo yeoyile, kwaye ubunzulu bayo buyahluka ngokobunzima bempazamo, okubonakalisa ukuhamba komoya kunye nokuhamba kweoyile. Ukhuseleko lwesenzo lubizwa ngokuba lukhuselo lwegesi, olukwabizwa ngokuba lukhuselo lwegesi. Ngexesha lokusebenza kwetransformer, ngenxa yeempazamo zangaphakathi, ngamanye amaxesha asikwazi ukuchonga nokuthatha amanyathelo ngexesha, okulula ukubangela ezinye iingozi. Emva kokukhuselwa kwe-relay yegesi, ukwenzeka kweziganeko ezifanayo kunokuthintelwa ukuya kwinqanaba elithile.

1. Yintoni i-transformer?


Kwisekethe ye-AC, isixhobo esonyusa okanye esinciphisa i-voltage sibizwa ngokuba yi-transformer. I-transformer inokuguqula naliphi na ixabiso le-voltage libe lixabiso le-voltage esilifunayo nge-frequency efanayo ukuhlangabezana neemfuno zokuhambisa, ukusasaza kunye nokusetyenziswa kwamandla ombane.


Umzekelo, umbane ovela kwisikhululo samandla unenqanaba eliphantsi le-voltage, kwaye i-voltage kufuneka yonyuswe ngaphambi kokuba ithuthwe iye kwindawo ekude yokusebenzisa umbane. Indawo yokusebenzisa umbane kufuneka incitshiswe ibe kwinqanaba elifanelekileyo le-voltage ukuze kubonelelwe ngezixhobo zombane kunye nombane wemihla ngemihla. Izixhobo.

Umbuzo:
"Kukho i-transformer yakudala ye-1000KVA enomthwalo okhoyo omalunga ne-200KW. Ukuba kuza kongezwa umthwalo omtsha omalunga ne-600KW, ngaba le transformer ingamelana nayo?"
