1.1 Nkọwa oru ngo

2000 kVA three phase pad mounted transformer e bugara na USA na 2025. The gosiri ike nke transformer bụ 2000 kVA na KNAN jụrụ oyi. The elu voltaji bụ 13.2GrdY / 7.621 kV na ± 2 * 2.5% tapping nso (NLTC), obere voltaji bụ 0.48Y / 0.277 kV, ha guzobere vector otu YNyn0.

Ezubere maka ntinye enweghị nkebi n'ime sistemu nkesa ọkụ eletrik dị n'okpuru ala, ihe mgbakwasa pad ahụ bụ ihe ngwọta dị elu- na-aga nke ọma na mgbada voltaji - na nkwụsi ike ọkọnọ ike. N'ịgbaso ụkpụrụ nchekwa ume ike DOE, a na-emezi ihe ngbanwe a maka obere-ibu na ibu ibu-, na-ebuga arụmọrụ ike dị elu nke na-atụgharị gaa na nchekwa ego buru ibu karịa ndụ ọrụ ya. N'isi nke ọrụ ya a pụrụ ịdabere na ya bụ mmanụ mkpuchi FR3 eke ester, nke na-enye conductivity thermal conductivity na ike njikwa mmiri dị mma, na-eme ka ihe ngbanwe ahụ nwee ike ijikwa ibu 20% dị elu ma e jiri ya tụnyere mmanụ ịnweta mmanụ {{8}juju nkeji ka ọ na-ejigide ọnọdụ okpomọkụ dị ala. Iji hụ na arụrụ ọrụ anaghị akwụsị akwụsị, ihe ngbanwe a nwere ihe njide arụmarụ dị elu{10} nke na-atụgharị ebili mmiri na-echekwa ihe ndị dị n'ime ya pụọ ​​​​na mkpọda voltaji. Ọta static agbakwunyere na-akwalite ike dielectric, na-egbochi ndakpọ mkpuchi na ịgba mbọ hụ na nnyefe ike kwụsiri ike. Maka ịdị mfe nke nlekota na mmezi, a na-etinye igbe nlele raara onwe ya nye n'akụkụ, na-enye ohere ịnweta data arụmọrụ ngwa ngwa.
