Ngwunye Transformer nke e ji mmanụ mee: Nghọta teknụzụ na atụmatụ imewe

Transformer nke e ji mmanụ mee windings bụ ihe dị mkpa na sistemụ nkesa ike, nke e mere iji nyefee ike eletrik nke ọma ma hụ na a pụrụ ịtụkwasị obi ma sie ike. N'okpuru ebe a bụ nyocha zuru ezu nke nhazi ha, ihe ndị e ji rụọ ha, na ụkpụrụ ọrụ ha, nke e si n'ụkpụrụ ụlọ ọrụ na nkọwapụta teknụzụ mepụta.

A machibidoro okpomọkụ elu nke transformer e mikpuru na mmanụ ka ọ ghara ịgafe 95 Celsius C, a na-amachibidokarị ya ịgafe 85 Celsius C, nhọrọ winding transformer izugbe nke ihe mkpuchi mkpuchi klas A, okpomọkụ kachasị ekwe omume nke ihe mkpuchi bụ 95 ~ 105 Celsius C, na nkọwapụta okpomọkụ transformer nke China dabere na okpomọkụ ọrụ nke 40 Celsius C dị ka ọkọlọtọ, winding nke okpomọkụ nke gas nke dị na 65 Celsius C, Mmụba okpomọkụ nke mmanụ dị n'elu gaa na gas dị na 55 Celsius C, yabụ winding nwere isi transformer dị na mmụba okpomọkụ nke mmanụ na 10 Celsius C.

Ọ bụrụ na okpomọkụ dị elu nke transformer ahụ bụ 85 Celsius, okpomọkụ nke ịgbagharị bụ 95 Celsius; Ọ bụrụ na okpomọkụ dị elu bụ 95 Celsius, okpomọkụ nke ịgbagharị erutela 105 Celsius, nke erutela okpomọkụ kachasị mma nke ihe mkpuchi mkpuchi nke agbagharị. Oke okpomọkụ ga-eme ka ịka nká nke ihe mkpuchi mkpuchi dịkwuo ngwa ngwa, mee ka mmebi mmanụ transformer dịkwuo ngwa ngwa, mebie ndụ ọrụ nke Transformer nkesas, ma ọbụnakwa na-ebute ihe mberede nchekwa.

Sistemụ mgbasa mmanụ siri ike nke na-eme ka ikuku dị jụụ, okpomọkụ kachasị elu 75℃ na-ekpo ọkụ 35℃; Sistemụ mgbasa mmanụ sitere n'okike, nchebe oke okpomọkụ, transformer nke na-eme ka ikuku dị jụụ, okpomọkụ kachasị elu anaghị adabara maka ọtụtụ mgbe karịa 85 Celsius C, okpomọkụ dị elu agaghị agafe 95 ° C agaghị agafe 55 Celsius C, ọ bụrụ na achọpụta na ọrụ nke oke uru gafere ihe achọrọ, kwesịrị ịkọ akụkọ nhazi mmepụta ozugbo, ojiji nke oke ibu mgbochi.

1. Nkọwa na Ọrụ Isi

Mkpọchi transformer nke e tinyere mmanụ nwere eriri ọla kọpa ma ọ bụ aluminom gbara gburugburu isi ígwè silicon a kpụchara akpụcha. A na-emikpu windings ndị a kpamkpam na mmanụ mkpuchi, nke na-arụ ọrụ abụọ: mkpuchi eletriki na njikwa okpomọkụ. Windings ndị a na-agbanwe ntinye voltaji dị elu ka ọ bụrụ mmepụta voltaji dị ala (ma ọ bụ nke ọzọ) site na ntinye electromagnetic, na-eme ka nnyefe ike dị nchebe gafee grid.

2. ​Ihe mejupụtara ihe​

Ihe na-eduzi ihe:

​Ọla kọpa: A na-ejikarị ya eme ihe maka windings voltaji dị elu n'ihi ike ya dị elu na ike igwe. Windings voltaji dị ala (≤500 kVA) na-ejikarị usoro cylindrical okpukpu abụọ eme ihe, ebe ikike ndị ka ukwuu (≥630 kVA) na-eji nhazi double-helix ma ọ bụ quadruple-helix iji mee ka nkesa dị ugbu a ka mma.

Aluminom: A na-ejikarị ya eme ihe mgbe ụfọdụ maka ojiji dị oke ọnụ, mana ọ naghị arụ ọrụ nke ọma karịa ọla kọpa.
Ihe mkpuchi:

Ihe ndị na-eguzogide ọgwụ dị elu (dịka ọmụmaatụ, resin epoxy, akwụkwọ e ji cellulose mee) na-ekewapụ ihe ndị e ji agbanye n'etiti ha na ibe ha.

Mkpuchi ọtụtụ oyi akwa na-egbochi sekit dị mkpirikpi n'okpuru nrụgide okpomọkụ ma ọ bụ mgbanwe igwe.

3. Nhazi ihe owuwu

Nhazi nke Wrinding:

Ngagharị Concentric (Cylindrical): A na-ahụkarị ya na transformers nke nwere usoro atọ, ebe a na-etinye windings voltaji dị ala n'ime windings voltaji dị elu iji belata mmiri mmiri na-agbapụta.

Nchigharị nke ọnya oyi akwa (Helical): A na-eji ya eme ihe maka ojiji dị elu, na-egosipụta akwa dị iche iche iji belata mfu nke ikuku.

Njikọta nke Jụụ:

Ihe ndị a na-akpọ windings na-agụnye ọkpọkọ mmanụ iji mee ka okpomọkụ gbasaa site na ikuku ma ọ bụ nke a na-amanye.

Tankị mmanụ e ji ígwè rụọ na-anọchi anya ihe nchekwa ọdịnala, na-ekwe ka mmanụ gbasaa okpomọkụ ma na-echekwa gburugburu ebe obibi mechiri emechi.

4. Nhazi arụmọrụ

Nhazi Mfu Dị Ala:

Amorphous Alloy Cores: Belata mfu hysteresis na eddy current (dịka ọmụmaatụ, transformers usoro S11-M na-enweta mfu dị ala karịa ụdị ochie 30%)

Dyn11 Connection Group: Na-ebelata mgbawa harmonic ma na-eme ka ike dị mma site na ịgbasa ọkụ eletrik nke atọ

Nguzogide Dị Mkpirikpi:

Usoro ihe mkpuchi a na-eme ka ọ sie ike na usoro ịgbagharị gburugburu na-eme ka usoro kwụsie ike n'oge nsogbu.

Igwe mmiri silica gel na Buchholz relays na-enyocha nsogbu mmiri na mmiri na-asọba na mmanụ.

5. ​Ntinye na Mmezi​

Ọnọdụ mmepụta:

Ebe ndị na-arụ ọrụ n'ime ụlọ ọrụ mmepụta ihe, ebe a na-eji ike eme ihe n'obodo ukwu, na sistemụ ike mmeghari ohuru (dịka ọmụmaatụ, ugbo ikuku).

Ike ndị a tụrụ anya ya dị site na 50 kVA ruo 25,000 kVA, yana voltaji ruru 35 kV

Usoro Mmezi:

Nnwale mmanụ nkịtị na nyocha gas agbazere agbaze (DGA) iji chọpụta mmebi mkpuchi.

Foto okpomọkụ iji chọpụta ebe ndị dị nso na windings.

6. Mmepụta ihe ọhụrụ na Teknụzụ Winding

Ntinye ihe mkpuchi vacuum: Na-ewepụ akpa ikuku n'oge nrụpụta, na-eme ka iguzosi ike n'ezi ihe mkpuchi dịkwuo mma

Nlekota anya smart: Ihe mmetụta IoT na-enyere aka na-esochi okpomọkụ na ike ibu n'oge.
