6 MVA Igwe ọkụ eletrik na-eme mgbanwe-33 / 2.2 kV|South Africa 2025

 

 

01 Izugbe

1.1 Nkọwa oru ngo

Mmanụ 6MVA a -emikpuike transformerE zigara South Africa na 2024 maka ojiji na sistemụ inverter. Ihe ntụgharị ọkụ eletrik 6 MVA nwere ikike nke 6000 kVA, voltaji bụ isi nke 33 kV, na voltaji nke abụọ nke 2.2 kV. Ọ na-agbaso ụkpụrụ IEC 60076 nke ọma

Ọ bụ ezie na ndị inverters nwere ike ịtụgharị ike DC ka ọ bụrụ ike AC, voltaji grid na-adịkarị elu karịa onye inverter nwere ike idi. Iji hụ na arụ ọrụ nke sistemu adịghị mma, onye ngbanwe anyị na-agbadata voltaji dị elu nke grid (33kV) ruo 2.2 kV nke ndị inverter na-anabata. Ihe ngbanwe ahụ na-enyekwa ikewapụ ọkụ eletrik, nkwekọ ekwekọ, na nchedo sistemu, na-ahụ maka ọrụ nchekwa na kwụsiri ike n'etiti ihe ntụgharị na grid.

Ọ na-anya isi arụmọrụ dị elu. Mba - mfu efu dị obere ka 6.2 kW, na mfu efu dị obere ka 39 kW, na-ebelata oriri ume na ụgwọ ọrụ. Ihe mgbochi 7% na-eme ka voltaji kwụsie ike n'ọnọdụ dị mkpirikpi{6}, na ikuku ọla kọpa na-enye ezigbo conductivity, na-echebe ma inverter na grid.

Igwe ọkụ eletrik 6 MVA jupụtara na PCB{1}} mmanụ mkpuchi ịnweta ịnweta n'efu, na-akwalite nchekwa gburugburu ebe obibi. Sistemu jụrụ oyi na-eji ikuku jụrụ oyi ma nwee igwe ọkụ - itinye galvanized radiator. Nke a na-eme ka mgbasa ọkụ dị mma na nguzogide ihu igwe siri ike, na-eme ka ha dị mma maka gburugburu mpụga South Africa.

Ngwa ngwa ngwa gụnyere ihe nleba ọkwa mmanụ, valve enyemaka nrụgide, ngwaọrụ nlekota mmanụ na ikuku ikuku, Buchholz relay, na respirator, na-eme ka ọrụ nchekwa na kwụsie ike na ịgbatị ndụ akụrụngwa. Site na arụmọrụ ya dị elu, mfu dị ala, yana imewe siri ike, mmanụ 6MVA a{2}} ihe ngbanwe ike imikpu abụghị naanị ezigbo nhọrọ maka grid inverter{3} ejikọrọ, mana ọ bụkwa isi akụrụngwa ntụkwasị obi maka ọrụ ike ike ọhụrụ.
