Ihe ọmụma zuru oke nke nchekwa na nchekwa ndabere Transformer Main

Transformer bụ ọrụ na-aga n'ihu nke akụrụngwa kwụsiri ike, ọrụ a pụrụ ịtụkwasị obi karịa, obere ohere nke ịda ada. Mana n'ihi na a na-etinye ọtụtụ transformers n'èzí, ọrụ nke ibu na mmetụta nke mmebi sekit dị mkpụmkpụ nke sistemụ ike na-emetụta ha, n'oge ọrụ, enwere ụdị mmebi na ọnọdụ ndị na-adịghị mma niile.

1. Mmejọ na ihe ndị na-adịghị mma nke transformers na-emekarị

2. Nhazi nke nchekwa transformer

3. Nchedo na-abụghị ọkụ eletrik

(1) Nchedo gas

(2) Nchedo nrụgide

(3) Nchedo okpomọkụ na ọkwa mmanụ

(4) Nchedo nkwụsị zuru oke nke oyi

4. Nchedo dị iche iche

(1) Ọsọ inrush magnetization nke transformer

(2) Ụkpụrụ nke njide harmonic nke abụọ

(3) Nchedo dị iche iche nke mgbawa ngwa ngwa

Kọwaa nke a n'ụzọ dị mkpirikpi gbasara nchekwa isi nke transformer, ma gaa n'ihu na-ewebata nchekwa ndabere nke transformer. E nwere ọtụtụ ụdị nhazi nchekwa ndabere maka transformer. Nke a bụ obere okwu mmalite maka ụdị nchekwa ndabere abụọ ahụ, nchekwa oke ọkụ na nchekwa ala nke transformer.

1. Nchedo oke ọkụ na mkpọchi nrụgide ọzọ

2. Nchekwa ala nke transformer

Nchedo ndabere maka nsogbu sekit dị mkpụmkpụ nke transformers buru ibu na nke etiti na-agụnyekarị: nchebe oke ọsọ nke usoro efu, nchedo oke voltaji nke usoro efu, nchedo oghere, wdg. Ihe na-esonụ bụ okwu mmalite dị mkpirikpi dabere na ụzọ atọ dị iche iche nke isi ihe na-anọpụ iche.

(1) Isi ihe na-anọpụ iche bụ ntọala kpọmkwem

(2) Isi ihe na-anọpụ iche abụghị ihe ndabere

(3) Ebe a na-anọpụ iche dị n'okpuru ala site na oghere mwepụta

Transformers voltaji dị elu nke ukwuu bụ transformers ọkara-insulated, mkpuchi ala nke coil point na-anọpụ iche adịghịkwa ike karịa akụkụ ndị ọzọ. A na-agbaji mkpuchi point na-anọpụ iche ngwa ngwa. Ya mere, ọ dị mkpa ka ahazi nchedo oghere.

Ọrụ nke nchekwa oghere bụ ichekwa nchekwa mkpuchi nke ebe na-anọpụ iche nke ebe na-anọpụ iche nke transformer ahụ.

A na-enweta nchedo oghere site na iji oghere 3I0 nke na-agafe ebe na-anọpụ iche nke transformer na voltaji delta mepere emepe 3U0 nke busbar PT dị ka ihe achọrọ.

Ọ bụrụ na ebe ntụpọ ahụ na-anọpụ iche ruo ebe ahụ, oghere ahụ na-agbaji ma mepụta nnukwu oghere 3I0. N'oge a, a na-arụ ọrụ nchebe oghere ahụ ma na-ebipụ transformer ahụ mgbe igbu oge gasịrị. Na mgbakwunye, mgbe nsogbu ala mere na sistemụ ahụ, a na-akụda ebe na-anọpụ iche ma na-arụ ọrụ nchebe usoro efu nke transformer ahụ, a na-akụda ebe na-anọpụ iche mbụ. Mgbe sistemụ ahụ tụfuru ebe ntọala, ọ bụrụ na nsogbu ahụ ka dị, voltaji delta mepere emepe 3U0 nke busbar PT ga-adị oke ukwuu, nchedo oghere ahụ ga-arụkwa ọrụ n'oge a.
