Nlebanya ule nlegharị anya na Korea

Na Dec., 2016, HV HIPOT engineer agba mbọ maka ịnwale Transformer Test Bench na Korea.Ebe a na-anwale ule bụ KEPCO, nke bụ nnukwu ọkụ eletrik na South Korea, na-ahụ maka ọgbọ, nnyefe na nkesa ọkụ eletrik na mmepe nke ọrụ ọkụ eletrik gụnyere ndị dị na ike nuklia, ikuku ikuku na kol.

Oche ule nke transformer nwere ike ịnwale ihe ahụ:
22.9kV Single Phase transformers na pụrụ iche transformers,ibu voltaji na ugbu a: AC 0-650V/78A, AC 0-1200V/29A, AC 0-2400V/14.6A.
The impedance nke nwalere transformer bụ n'ime 7%, HV akụkụ bụ 23kV, 11kV, 6kV.Akụkụ LV bụ 0.05kV-2.4kV.

Oche ule a nwere ike ime ule n'okpuru
1.Nnwale ọnweghị ibu gụnyere mfu enweghị ibu, pasentị nke enweghị ibu ugbu a ruo ugbu a akara.
2.Nnwale ibu gụnyere ọnwụ ibu, pasent voltaji impedance, mgbanwe okpomọkụ akpaka na ule ọnwụ n'okpuru 30% ma ọ bụ karịa zuru oke ugbu a.
3.Nnwale voltaji butere.

Atụmatụ
1.Iji aka dekọọ data ule wee chekwaa na nchekwa data.
2.Enwere ike idozi data nke ule enweghị ibu site na ụdị ifegharị na voltaji gosiri na-akpaghị aka.
3.Enwere ike idozi data nke ule Load site na okpomọkụ (75 ℃, 100 ℃, 120 ℃, 145 ℃) na akara ugbu a.
4.N'ime ule enweghị ibu, enwere ike nyochaa voltaji akụkụ LV.
5.N'ime ule ibu, enwere ike nyochaa akụkụ HV ugbu a.
6.Enwere ike ịhọrọ ma jikwaa ọrụ ule niile na usoro ule site na bọtịnụ nke n'ihu panel.
7.A na-edozi nsonaazụ ule niile dịka achọrọ GB1094, IEC60076 ma ọ bụ ANSI C57.
8.Enwere ike ịga n'ihu usoro ule site na ngwanrọ PC.
9.Enwere ike ịchekwa ma bipụta data niile.
10.Site na nchekwa efu, nchebe karịrị ugbu a yana ọrụ nchekwa voltaji.
11.CT/PT mgba ọkụ na-akpaghị aka.
12.Oche ule ga-ejikwa nke ọma na sekit loop dum wee nyochaa nha.
13.Sistemụ mkpu nchekwa.

Nhazi
A na-akwado ule niile achọrọ n'otu oche, ọrụ ọ bụla nwere onwe ya.Nnwale niile na-akpaghị aka.
Nnwale njirimara mgbanwe (Nnwale enweghị ibu na ibu)
PC na-achịkwa ya ma wetara ya onye na-achịkwa voltaji 100kVA, onye ntụgharị etiti 40kVA.

Anyị nwere ike hazie ụdị ọkwa dị iche iche dabere na ihe achọrọ n'ezie.
