Okwu mmalite
Transformer bụ ngwaọrụ kwụ ọtọ nke na-agbanwe ike eletrik AC site n'otu voltaji gaa na voltaji ọzọ na-edobe ugboro ole site na ụkpụrụ induction electromagnetic.
Ntinye na transformer na mmepụta si na transformer ha abụọ bụ alternating quantities (AC).A na-emepụta ike eletrik ma na-ebunye ya na oke voltaji dị oke elu. A ga-ebelata voltaji ahụ ka ọ bụrụ uru dị ala maka ojiji ụlọ na ụlọ ọrụ mmepụta ihe. Mgbe transformer na-agbanwe ọkwa voltaji, ọ na-agbanwekwa ọkwa dị ugbu a.
Ụkpụrụ ọrụ
A na-ejikọta ikuku nke mbụ na otu-phase ac ọkọnọ, ac current na-amalite na-asọ na ya. Ac bụ isi ugbu a na-emepụta mgbanwe mgbanwe (Ф) na isi. Ọtụtụ n'ime mgbanwe mgbanwe a na-ejikọta ya na ikuku nke abụọ site na isi.
Mgbanwe dị iche iche ga-ebute voltaji n'ime ikuku nke abụọ dịka iwu mmalite nke induction electromagnetic siri dị. Ọkwa voltaji na-agbanwe mana ugboro ole ya bụ oge na-anọgide otu. Enweghị kọntaktị eletrik n'etiti ikuku abụọ ahụ, a na-ebufe ike eletrik site na isi gaa na nke abụọ.

5.Oil okpomọkụ egosi
Ọ bụ ụdị temometa ọkpụkpọ, na-arụ ọrụ na ụkpụrụ nrụgide vapor. A makwaara ya dị ka magnetik oil gauge (MOG). O nwere otu ụzọ magnet. Mgbidi dara dara nke tankị nchekwa na-ekewa magnet na-enweghị ihe ọ bụla site na oghere. Ubi magnet na-apụta ma jiri ya mee ihe ngosi.
6.Winding okpomọkụ egosi
Ọ dịkwa ka OTI mana enwere mgbanwe ụfọdụ. Ọ mejupụtara nyocha nke etinyere na capillaries 2. A na-ejikọta capillaries na mgbịrị abụọ dị iche iche (na-arụ ọrụ / na-akwụ ụgwọ). Ejikọtara mgbịrịgba ndị a na ihe ngosi okpomọkụ.
7.Conservator
Ka mgbasawanye na mkpirisi na-apụta na nnukwu tank nke transformer, ya mere otu ihe ahụ na-eme na nchekwa nchekwa dịka ejikọrọ ya na nnukwu tank site na ọkpọkọ.
8.Nku ume
Nke a bụ ihe nzacha ikuku pụrụ iche na-etinye ihe na-eme ka mmiri gwụ mmiri, nke a na-akpọ, Silica Gel. A na-eji ya egbochi ntinye nke mmiri na ikuku emetọọ n'ime nchekwa nchekwa.
9.Radiators
A na-enye ndị na-eme mgbanwe nta na tubes jụrụ oyi welded ma ọ bụ radiators mpempe akwụkwọ mpempe akwụkwọ. Mana nnukwu mgbanwe na-enye radiators nwere ike ịpụpụ yana valvụ. Maka ntụ oyi ndị ọzọ, a na-enye ndị na-ekpocha ọkụ na radiators.
10. Kpatụ Changer
Ka ibu dị na transformer na-abawanye, voltaji nke abụọ na-ebelata. E nwere ụdị mgbanwe mgbata abụọ.
A. Gbanyụọ ihe mgbata mgbata
N'ụdị a, tupu ịkwaga onye na-ahọrọ, a na-eme ka transformer si na nsọtụ abụọ ahụ gbanyụọ. Ndị na-agbanwe mgbatụ ahụ nwere kọntaktsị ọla edo edobere, ebe akwụsịla mgbata. A na-eji ọla kọpa mee kọntaktị na-akpụ akpụ n'ụdị rola ma ọ bụ akụkụ.
B.On Load Tap Changer
Na nkenke anyị na-akpọ ya dị ka OLTC. N'ime nke a, enwere ike iji aka gbanwee taps site na arụ ọrụ igwe ma ọ bụ eletrik na-ewepụghị ihe ntụgharị. Maka ịrụ ọrụ igwe, a na-enye mkpọchi maka anaghị arụ ọrụ nke OLTC n'okpuru ọnọdụ mgbata kacha ala yana karịa ọnọdụ mgbata kacha elu.
11.RTCC (Cubicle mgbanwe mgbanwe mgbata dị anya)
A na-eji ya maka mgbanwe mgbata site na aka ma ọ bụ na-akpaghị aka site na AVR (Automatic Voltage Relay) nke atọrọ +/- 5% nke 110 Volt (Ntụaka ewepụtara site na voltaji PT nke abụọ).
