01 Gabaɗaya

1.1 Bayanin Aikin

Wani abokin ciniki na Afirka ta Kudu ya ba da umarnin a20MVA-33/6.65kV mataki saukar da wutan lantarkia watan Mayu 2025. Abokin cinikinmu yana samar da tasfoma, ƙananantashoshin sadarwada igiyoyin wutar lantarki zuwa ma'adanai na gida da na waje. Wannan transfomar kuma yana ɗaya daga cikin manyan injiniyoyin da aka keɓance don tashoshin ma'adinai. Kasar Afirka ta Kudu dai na daya daga cikin kasashen da suka ci gaba a fannin hakar ma'adinai, kuma ana bukatar taransfoma na ma'adinai.

Wannan matakin rage wutar lantarki ya ɗauki IEC 60076{10}}1:2011 misali. Yana ɗaukar hanyar sanyaya ONAN. Ƙungiyar Waya: YNyn0, dace da yanayin ƙasa mai rikitarwa. Kayan da ke jujjuyawa shine jan karfe, kuma asarar jan ƙarfe yana ƙasa. An ƙididdige shi a 33kV a gefen farko da 6.65kV a gefen sakandare. An sanye shi da mai sauya matsa lamba (OLTC) tare da kewayon tsari na ± 10 × 1%, yana ba da damar daidaita wutar lantarki a ƙarƙashin kaya, yana tabbatar da ingantaccen wutar lantarki ga kayan aikin hakar ma'adinai. Na'urar taswirar wutar lantarki tana samun kyakkyawan aikin makamashi, ba tare da asarar nauyi na 13.65 kW ba, asarar nauyi a digiri 75 na 132.8 kW, da kuma asarar gabaɗaya zuwa 72 kW. Don inganta motsi, musamman a wuraren hakar ma'adinai masu nisa, an ƙera na'urar taransifoma tare da manyan ƙafafu masu nauyi, fasalin da ke sauƙaƙa ayyukan yanar gizo.

Me yasa Ya dace don Aikace-aikacen Ma'adinai

A cikin ayyukan hakar ma'adinai, ingantaccen ingantaccen wutar lantarki yana da mahimmanci don tabbatar da aminci da yawan aiki. Wannan na'ura mai sarrafa wutar lantarki ya dace da yanayin rarraba wutar lantarki na ma'adinai:

Matsakaicin Fasa: Matakan ƙasa 33kV daga grid mai amfani ko tashoshin wutar lantarki zuwa 6.6kV, daidaitaccen ƙarfin lantarki don kayan aikin hakar ma'adinai.

Underground Power Delivery: Transmits 6.6kV power through cables to underground systems - an ideal voltage for long-distance transmission with low losses.

Babban -Aikin Kayan Aikin Wuta: Yana ba da iko mai nauyi{1}} injunan hakar ma'adinai kamar injinan ƙwallo, masu ɗaukar hoto, masu ba da iska, da famfunan cire ruwa.
