Transformers bụ ihe dị mkpa na sistemụ ike eletriki, na-eme ka nnyefe na nkesa ọkụ eletrik dị irè n'ebe dị anya. Ọ bụ ezie na transformers na-abịa n'ụdị na nhazi dị iche iche, ụdị transformers abụọ dị mkpa pụtara ìhè: transformers steepụ-elu na steepụ-ala.

N'isiokwu blọgụ a, anyị ga-enyocha ihe dị iche n'etiti transformers steepụ-elu na steepụ-ala, na-enyocha njirimara pụrụ iche ha, ụkpụrụ ọrụ, na ojiji a na-ejikarị eme ihe na ngalaba injinia eletriki.

Ndị na-eme mgbanwe mgbanwe

Kedu ihe bụ ihe na-eme ka mgbanwe steepụ dị elu

Transformers ndị a na-eme n'elu bụ ngwaọrụ eletriki e mere iji mee ka ọkwa voltaji dịkwuo elu site na winding mbụ ruo na winding nke abụọ.

ndị a ike transformers nwere eriri waya ọla kọpa abụọ e ji ihe mkpuchi kpuchie gburugburu otu isi, ebe eriri nke abụọ nwere ọtụtụ ntụgharị karịa eriri nke mbụ. Ọnụọgụ dị elu nke ntụgharị na eriri nke abụọ na-enye ndị na-agbanwe ihe mgbanwe steepụ aka ịtụgharị ike voltaji dị ala, nke dị elu ka ọ bụrụ ike voltaji dị elu, nke dị ala, nke na-eme ka ha dị mma maka nnyefe ike eletrik dị anya.

Olee otú Step-Up Transformers si arụ ọrụ

Ọrụ nke transformers steepụ-elu na-adabere na ụkpụrụ nke induction electromagnetic. Mgbe etinyere ọkụ eletrik (AC) na winding mbụ, ọ na-emepụta flux magnet n'ime isi transformer. Oghere magnetik a na-agbanwe agbanwe na-akpali ike electromotive (EMF) na winding nke abụọ, na-emepụta voltaji mmepụta nke dabara na oke nke ọnụọgụ ntụgharị na coil nke abụọ na coil nke mbụ.

Na transformers steepụ-elu, winding nke abụọ nwere ọtụtụ ntụgharị karịa winding mbụ, nke na-eme ka voltaji nke abụọ dị elu ma e jiri ya tụnyere voltaji mbụ. A maara oke ọnụọgụ nke ntụgharị na winding nke abụọ na winding mbụ dị ka oke mgbanwe, nke na-ekpebi oke voltaji mmepụta. Dịka ọmụmaatụ, ọ bụrụ na transformer steepụ-elu nwere winding mbụ nwere ntụgharị 100 na winding nke abụọ nwere ntụgharị 1,000, oke mgbanwe ga-abụ 10:1, nke pụtara na voltaji mmepụta ga-adị elu okpukpu iri karịa voltaji ntinye.

Mgbanwe voltaji na transformer steepụ na-agbaso usoro a:

V_s / V_p = N_s / N_p

ebe:

• V_s bụ voltaji nke abụọ (mpụta)
• V_p bụ voltaji mbụ (ntinye)
• N_s bụ ọnụọgụ nke ntụgharị na winding nke abụọ
• N_p bụ ọnụọgụ nke ntụgharị na winding mbụ

N'ime transformer steepụ-up, ọnụọgụ ntụgharị na winding nke abụọ (N_s) karịrị ọnụọgụ ntụgharị na winding mbụ (N_p). N'ihi ya, voltaji nke abụọ (V_s) ga-adị elu karịa voltaji mbụ (V_p), na-eme ka voltaji ahụ "rịa elu" nke ọma.

Mgbanwe dị ugbu a na transformer steepụ-up bụ nke dabara na mgbanwe voltaji. Ọ na-agbaso usoro a:

I_p / I_s = N_s / N_p

ebe:

• I_p bụ isi ugbu a (ntinye)
• I_s bụ nke abụọ (mmepụta) ugbu a

N'ime transformer steepụ elu, ka voltaji na-abawanye site na praịmarị ruo na winding nke abụọ, ọkụ eletrik na-ebelata. Nke a bụ n'ihi na ike (P) dị na transformer zuru oke na-anọgide na-agbanwe agbanwe, ike bụkwa ngwaahịa nke voltaji na ọkụ eletrik (P = V × I). Ọ bụrụ na voltaji ahụ amụba, ọkụ eletrik ga-ebelata iji nọgide na-enwe otu ọkwa ike ahụ.

Ndị na-eme mgbanwe na-agbada

Kedu ihe bụ Transformers Nzọụkwụ-Down

A mgbada-ala transformer bụ ụdị transformer nke na-agbanwe ike voltaji dị elu, nke na-agbanwe ike voltaji dị ala ka ọ bụrụ ike voltaji dị ala, nke na-agbanwe ike voltaji dị elu.

Transformers ndị na-agbada n'ọkwa nwere usoro coil abụọ, nke a maara dị ka windings mbụ na nke abụọ, nke e ji ihe magnetik dịka ígwè ma ọ bụ ígwè kee gburugburu isi ihe a na-ejikarị eme ihe. Winding nke mbụ na-enweta ntinye voltaji dị elu, ebe winding nke abụọ na-enye mmepụta voltaji belatara.

Olee otú Step-down Transformers si arụ ọrụ

Ụkpụrụ ọrụ nke transformers step-down dabere na iwu Faraday nke electromagnetic induction. Mgbe etinyere ọkụ eletrik (AC) na winding mbụ, ọ na-emepụta mgbanwe magnetik flux n'ime isi transformer. Oghere magnetik a na-agbanwe agbanwe na-akpali ike electromotive (EMF) na winding nke abụọ, na-emepụta voltaji mmepụta nke dabara na oke nke ọnụọgụ ntụgharị na coil nke abụọ na ọnụọgụ ntụgharị na coil nke mbụ.

N'ime transformer nke na-agbada n'ọkwa, winding nke abụọ nwere obere ntụgharị karịa winding nke mbụ. N'ihi ya, voltaji e tinyere na coil nke abụọ dị ala karịa voltaji ntinye etinyere na coil nke mbụ. Agbanyeghị, dịka iwu nchekwa ike si dị, ọkụ dị na winding nke abụọ na-abawanye n'ụzọ nhata iji nọgide na-enwe nnyefe ike mgbe niile (na-ewere transformer zuru oke na-enweghị mfu).
