1.1 Ihe ndabere oru ngo

Ebupụrụ nkeji abụọ nke 63MVA Power transformers na South Africa na July 2024. Voltage dị 242 ruo 10.5 kV, 242 kV isi, 10.5 kV nke abụọ. A na-eji ihe ngbanwe abụọ a na-arụ ọrụ na ọdụ ọkụ fotovoltaic na South Africa.

Nke a 63MVA, 242/10.5 kV ike transformer bụ injinia dị ka isi nkuku a pụrụ ịdabere na ya nke ọma na nke dị mma maka mgbasa ozi eletriki na netwọk nkesa. Ọ na-eji nke ọma gbadata ọkụ eletrik dị elu{4} site na 242 kV ruo 10.5 kV, na-enye ọkụ kwụsiri ike ma na-aga n'ihu maka ụlọ ọrụ mmepụta ihe na grids ime obodo. Site n'ikike ya siri ike, a na-ewu ngalaba ahụ ka ọ na-arụ nnukwu ibu ka ọ na-etinye atụmatụ dị elu iji belata mfu, na-ahụ na ike dị elu, mbelata ụgwọ ọrụ yana nkwalite ịdịte aka. N'ezie, ọ na-anọchi anya ngwakọta zuru oke nke arụmọrụ siri ike yana imewe ọgụgụ isi, na-ekwe nkwa nkwụsi ike grid yana ije ozi dị ka itinye ego ntụkwasị obi maka ọdịnihu ike na-adigide.

2.1 Isi

Isi nke 63MVA, 242/10.5 kV transformer bụ nkenke{3}}wuru site na iji obere mfu{4}}, oyi -ọka akpọre akpọre -Slicon steel. Ọ na-egosipụta usoro nhazi ọkwa kachasị mma -nke na-ebelata ike ndọta ma na-ebelata nnukwu mfu (enweghị-mfu ibu). Nke a na-eme ka arụmọrụ dị elu, ọnụ ahịa ọrụ dị ala, yana arụ ọrụ dị jụụ, ntụkwasị obi n'okpuru ọrụ na-aga n'ihu.

2.2 Ikuku

Ihe ngbanwe a na-eji ihe nrụnye diski na-aga n'ihu, nke ama ama maka ike ọrụ ya pụrụiche iji guzogide ike mkpirisi-. Ihe owuwu a siri ike, nke emere site na onye nduzi akụkụ anọ mkpuchi mkpuchi n'ime usoro diski ejikọtara ọnụ, na-eme ka mgbasa ọkụ dị mma yana ntụkwasị obi, ogologo oge-. Ọdịdị monolithic na-enweghị nkwonkwo na-enye nkwụsi ike eletrik na arụmọrụ pụtara ìhè.

2.3 tank

A na-arụ tankị nke 63MVA, 242/10.5 kV ike transformer site na efere ígwè siri ike, nke na-egosipụta akụkụ corrugated ma ọ bụ nku jụrụ oyi maka ịgbasa ọkụ dị mma site na elu elu. Nhazi ya nke ejiri mechiri emechi na-eme ka a mata ikewapụ oke mmiri na ikuku oxygen, na-echekwa iguzosi ike n'ezi ihe nke mmanụ. Ejiri ngwa ngwa ọkọlọtọ gụnyere nchekwa nchekwa, nrụgide - ngwaọrụ mwepụta, yana nleba anya, tank ahụ na-enye ebe nchekwa na nchekwa maka isi na ikuku, na-ekwe nkwa ogologo oge- ntụkwasị obi n'okpuru ihe arụ ọrụ na-aga n'ihu.

The tank nke 63MVA, 242/10.5 kV ike transformer si otú na-anọchi anya dị oké egwu interface n'etiti unit si n'ime kacha mma na mpụga ọrụ ọnọdụ. Ihe owuwu ya siri ike, sistemu njikwa ọkụ na-arụ ọrụ nke ọma, yana mkpuchi hermetic na-arụkọ ọrụ ọnụ iji mepụta ebe nchekwa kwụsiri ike maka isi na ikuku. Nke a na-eme ka ihe nrụzi nke ihe ngbanwe n'okpuru nrụgide electromagnetic na-ejigide ike dielectric nke mmanụ mkpuchi n'ime ogologo oge. N'ikpeazụ, tank ahụ abụghị naanị akpa kama ọ bụ nkwa ntọala nke ntụkwasị obi na-arụ ọrụ nke transformer, nchekwa na ogologo ndụ ọrụ, na-eme ka ọrụ ya sie ike dị ka ihe a pụrụ ịdabere na ya na akụrụngwa ike.
