01 Izugbe

1.1 Ihe ndabere oru ngo

N'afọ 2025, a75 kVA otu -osisi n'usoro{2}} n'agbanyere ngbanwee zigara Canada maka ọrụ nkesa n'elu. Emebere ya na mpaghara ime obodo dị jụụ iji zụọ ọtụtụ ụlọ na obere azụmaahịa mpaghara site na ahịrị 14.4 kV. Mpaghara ahụ na-echekarị oyi na-atụ oyi na oke mmiri mberede, yabụ na igwe ngbanwe ihe dị 75 kVA kwesịrị ịdị ike nke ukwuu iji mee ka ike kwụsie ike n'agbanyeghị ihu igwe.

Ngalaba ahụ na-agbaso ụkpụrụ CSA C2.2{9}}06 ma na-agba na 24.94GrdY/14.4 kV ruo 120/240 V, 60 Hz. Ọ na-eji ONAN jụrụ oyi na aluminom windings, yana mgbochi 3% maka ụkpụrụ voltaji siri ike. Enweghị - ihe na-agbanwe ihe mgbata (± 2×2.5%) na-eme ka ọ dị mfe imezi{17}}imezi mmepụta mgbe achọrọ ya. Site na mfu nke 141 W yana mfu nke 1,160 W, transformer na-arụ ọrụ nke ọma n'iji ya eme ihe kwa ụbọchị{18}.

Ọ na-abịakwa na nkwado njide abụọ na onye nchọpụta ihe kpatara nsogbu (IFD) nke na-enye mgbaama anya ngwa ngwa ma ọ bụrụ na ihe ọ bụla na-adaba n'ime, ya mere ndị ọrụ nlekọta nwere ike ime ihe ozugbo. Kọmpat, siri ike ma dị mfe iji wụnye, ihe ngbanwe akụrụngwa a dabara nke ọma na mpaghara ebe obibi, netwọk ime obodo, na sistemụ ọkụ ọha, na-ebuga ike nchekwa na ntụkwasị obi n'ofe Canada.

2.1 Isi

Utility transformer core nakweere nhazi isi ọnya dị elu{0}, na-eme ka sekit magnetik kọmpat yana mbelata mfu. Nrụpụta nkenke na silicon steel lamination na-arụpụta ezigbo arụmọrụ{2}}ọ dịghị- ibu mfu tụrụ na 0.128 kW (nke a tụrụ), 0.145 kW (voltaji 105%), na mkpali dị ugbu a dị obere ka 0.18%, na-egosi arụmọrụ pụtara ìhè.

2.2 Ikuku

Ihe ngbanwe ngwa ngwa 75 kVA na-ewere usoro abụọ-ikuku, otu{2}} nwere polarity mgbakwunye (vector group Ii6). Igwe ikuku - voltaji dị ala na-eji foil aluminom, na-enye ọmarịcha mkpirisi ike mkpirisi na ikpo ọkụ, ebe ọ na-ahụkwa na owuwu dị fechaa. A na-eji waya okirikiri ọla kọpa mee ikuku-voltaji dị elu, na-eme ka omume dị elu, ike igwe, na nkwụsi ike ọkụ ruo ogologo oge- ntụkwasị obi.

2.3 tank

A na-eji ihe niile dị na tank mmanụ emepụta ihe<1mm tolerance, using flat, rust-free steel plates that meet national standards. Welds are continuous, clean, and defect-free. Inner and outer splatter is thoroughly removed, especially around radiator bases and lifting lugs. Each transformer tank undergoes a 12-hour airtight test at 20kPa, ensuring no leakage. Structural strength and sealing performance meet or exceed quality requirements.
