Eli nqaku libala ikakhulu iintlobo ezisi-7 zeendlela zokugweba iimpazamo kunye nohlalutyo lwesisombululo sengxolo ye-transformer yohlobo olomileyo. Ukuba kukho impazamo okanye ukushiywa, nceda uyibonise kwindawo yezimvo.
Uhlalutyo lweentlobo ezi-7 zeendlela zokugweba iimpazamo kunye nezisombululo zengxolo ye-transformer yohlobo olomileyo
➢Iingxaki zeresonance zefeni, iikhava kunye nezinye izinto
➢Iingxaki zokufakelwa
➢Impembelelo yendawo yokufakela
➢Ingxaki yokungcangcazela kwebhulorho yebhasi

Izixhobo zokukhusela ezifanelekileyo kufuneka zifakelwe iimpazamo ze-short-circuit zeengcingo ze-transformer lead, ii-bushings kunye nezangaphakathi, kwaye ziya kuhlangabezana neemfuno ezilandelayo:
1) I-transformer esebenza ngombane enye ye-10MVA nangaphezulu kunye ne-transformer esebenza ngombane efanayo ye-6.3MVA nangaphezulu kufuneka zixhotyiswe ngokhuseleko lokwahluka olude. Ii-transformer ezibalulekileyo ezine-6.3MVA nangaphantsi ezisebenza ngokuzimeleyo nazo zinokuxhotyiswa ngokhuseleko lokwahluka olude.
2) Iitransformer ezingaphantsi kwe-10MVA zinokuxhotyiswa ngokhuseleko lwangoku olukhawulezayo kunye nokhuseleko lwangoku olugqithisileyo. Kwiitransformer ze-2MVA nangaphezulu, xa i-coefficient yangoku yokuguquguquka okukhawulezayo ingahlangabezani neemfuno, kufuneka kufakwe ukhuseleko lokwahluka kwe-longitudinal.
3) 0.4MVA nangaphezulu, i-voltage yokuqala yi-10kV nangaphantsi, kwaye i-coil yi-transformer enonxibelelwano lwe-delta-star, kwaye ukhuseleko lwe-overcurrent olunezigaba ezimbini ze-relay ezintathu lungasetyenziswa.
4) Izixhobo ezahlukeneyo zokukhusela ezichazwe kweli nqaku ziya kusebenza ukuze zikhuphe ii-circuit breakers kumacala omabini e-transformer.

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).

Inkqubo yokupholisa ye-power transformer inamacandelo amabini: inkqubo yokupholisa yangaphakathi, eqinisekisa ukuba ubushushu bokujika kunye nombindi wentsimbi buyasasazeka kwindawo ejikelezileyo; inkqubo yokupholisa yangaphandle, eqinisekisa ukuba ubushushu obukwindawo busasazeka ngaphandle kwe-transformer. Ngokobukhulu bomthamo we-transformer, indawo kunye nohlobo lokujikeleza, i-transformer isebenzisa iindlela ezahlukeneyo zokupholisa.

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.

Kutshanje, iCANWIN yamkele iqela elikhethekileyo labathengi - abathengi bamanye amazwe abafunde ngathi ngeqonga loshishino lwamandla lwamazwe ngamazwe kwaye beza ngokukodwa ukutyelela inkqubo yokwenziwa kwetransformer. Iqela lezorhwebo langaphandle lamkele ngokufudumeleyo abathengi abavela kude laza labapheleka ukuya kumgca wemveliso, besenza uhlolo kwindawo yonke yenkqubo yokwenziwa kwetransformer.

Bahlobo bam abathandekayo nabahlobo beli shishini, Molo!
Siyavuya ukuvakalisa ukuba inkampani yethu iza kuthatha inxaxheba kwiCWIEME eBerlin 2026 ukususela nge-19 ukuya kwi-21 kaMeyi 2026. Oku kuza kusebenza njengeqonga elibalulekileyo lokubonisa iimveliso zethu zamva nje, ubuchwepheshe kunye nezisombululo.
Ngelo xesha, iqela lethu eliphambili, kuquka iingcali zobugcisa kunye neenkokheli zoshishino, liya kubakho apho. Simema ngokunyanisekileyo bonke amaqabane kunye nabahlobo babathengi ukuba batyelele iNombolo yethu yeBooth: Hall 3.2 (32 C30) ukuze banxibelelane ubuso ngobuso.

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.

Kwakamsinya nje emva kokuba i-transformer ivuliwe, kubakho isandi esirhabaxa, ikakhulu ngenxa yesiphumo se-magnetic flux enamandla aphezulu. Ngexesha lokusebenza okuqhelekileyo, isandi se-transformer siyafana. Xa kukho ezinye iingxolo, unobangela kufuneka uphandwe ngononophelo kwaye ujongwane nawo.
