E nwere ihe achọrọ maka teknụzụ dị iche iche maka ụdị transformers dị iche iche, nke enwere ike igosipụta site na paramita teknụzụ kwekọrọ. Dịka ọmụmaatụ, paramita teknụzụ bụ isi nke transformer ike gụnyere: ike enyere, oke voltaji na voltaji enyere, ugboro ole enyere, ọkwa okpomọkụ ọrụ, mmụba okpomọkụ, ọnụego nhazi voltaji, arụmọrụ mkpuchi na iguzogide mmiri. Maka transformers obere ugboro n'ozuzu, paramita teknụzụ bụ isi bụ: oke mgbanwe, njirimara ugboro ugboro, mgbagọ na-abụghị ahịrị, nchekwa magnet na nchekwa electrostatic, arụmọrụ, wdg.
Isi ihe dị na transformer gụnyere oke voltaji, njirimara ugboro ugboro, ike a tụrụ na arụmọrụ.
(1）Oke voltaji
Mmekọrịta dị n'etiti oke voltaji n nke transformer na ntụgharị na voltaji nke windings mbụ na nke abụọ bụ dịka ndị a: n=V1/V2=N1/N2 ebe N1 bụ winding mbụ (nke mbụ) nke transformer, N2 bụ winding nke abụọ (nke abụọ), V1 bụ voltaji na nsọtụ abụọ nke winding mbụ, na V2 bụ voltaji na nsọtụ abụọ nke winding nke abụọ. Oke voltaji n nke transformer stee-up erughị 1, oke voltaji n nke transformer stee-down karịrị 1, oke voltaji nke transformer seeling rate hà nhata 1.
(2）Ike e nyere ọkwa P A na-ejikarị paramita a eme ihe maka transformers ike. Ọ na-ezo aka na ike mmepụta mgbe transformer ike nwere ike ịrụ ọrụ ogologo oge na-agaghị agafe okpomọkụ akọwapụtara n'okpuru ugboro ọrụ na voltaji akọwapụtara. Ike transformer nke a nyere ọkwa metụtara mpaghara nke isi ígwè, dayameta nke waya enamel, wdg. Transformer ahụ nwere nnukwu mpaghara nke isi ígwè, dayameta waya enamel dị arọ na nnukwu ike mmepụta.
(3）Njirimara ugboro ugboro Njirimara ugboro ugboro na-egosi na transformer nwere oke ugboro ọrụ ụfọdụ, a pụghịkwa ịgbanwe transformer nwere oke ugboro ọrụ dị iche iche. Mgbe transformer ahụ na-arụ ọrụ karịa oke ugboro ya, okpomọkụ ga-ebili ma ọ bụ transformer agaghị arụ ọrụ nke ọma.
(4）Arụmọrụ na-ezo aka na oke ike mmepụta na ike ntinye nke transformer na ibu a tụrụ. Uru a dabara na ike mmepụta nke transformer, ya bụ, ka ike mmepụta nke transformer na-abawanye, otú ahụ ka arụmọrụ ka mma; Ka ike mmepụta nke transformer pere mpe, otú ahụ ka arụmọrụ dị ala. Uru arụmọrụ nke transformer na-adịkarị n'etiti 60% na 100%.
Na ike enyere ikike, a na-akpọ oke ike mmepụta na ike ntinye nke transformer arụmọrụ transformer, ya bụ, arụmọrụ transformer.
η= x100%
Ebeeη Ọ bụ arụmọrụ nke transformer; P1 bụ ike ntinye na P2 bụ ike mmepụta.
Mgbe ike mmepụta P2 nke transformer hà nhata ike ntinye P1, arụmọrụ ya bụ arụmọrụη Dịka ọ dị na 100%, transformer agaghị eweta mfu ọ bụla. Mana n'eziokwu, ọ dịghị transformer dị otu a. Mgbe transformer na-ebunye ike eletrik, ọ na-emepụta mfu mgbe niile, nke gụnyere mfu ọla kọpa na mfu ígwè.
Mfu ọla kọpa na-ezo aka na mfu nke iguzogide eriri nke transformer kpatara. Mgbe a na-ekpo ọkụ ọkụ site na nguzogide eriri kọlụm, akụkụ nke ike eletriki ga-agbanwe ka ọ bụrụ ike okpomọkụ ma furu efu. Ebe ọ bụ na waya ọla kọpa a na-etinye mkpuchi na-emerụ eriri kọlụm ahụ, a na-akpọ ya mfu ọla kọpa.
Mfu ígwè nke transformer gụnyere akụkụ abụọ. Otu bụ mfu hysteresis. Mgbe ọkụ AC gafere na transformer, ntụziaka na nha nke eriri magnetik nke na-agafe na mpempe ígwè silicon nke transformer ga-agbanwe dịka o kwesịrị, na-eme ka molekul dị n'ime mpempe ígwè silicon na-ata ibe ha ma na-ewepụta ike okpomọkụ, si otú a na-efunahụ akụkụ nke ike eletriki, nke a na-akpọ mfu hysteresis. Nke ọzọ bụ mfu ugbu a eddy, mgbe transformer na-arụ ọrụ. E nwere ahịrị ike magnetik nke na-agafe na isi ígwè, a ga-emepụtakwa ọkụ eletrik a na-akpali akpali na mbara igwe kwụ ọtọ na ahịrị ike magnetik. Ebe ọ bụ na ọkụ a na-emepụta okirikiri mechiri emechi ma na-agagharị n'ụdị whirlpool, a na-akpọ ya ọkụ eddy. Ịdị adị nke ọkụ eddy na-eme ka isi ígwè ahụ kpoo ọkụ ma na-eri ike, nke a na-akpọ mfu ugbu a eddy.
Arụmọrụ nke transformer nwere njikọ chiri anya na ọkwa ike nke transformer. N'ozuzu, ike ka ukwuu, otú ahụ ka mfu na mmepụta na-adị obere, otú ahụ ka arụmọrụ ka ukwuu. N'ụzọ megidere nke ahụ, otú ahụ ka ike dị obere, otú ahụ ka arụmọrụ dị ala.
