I te mea kei te haere tonu ngā panonitanga o te ahumahi, me ōna painga ahurei me ōna tirohanga whānui mō te whanaketanga, kei te puta haere te oumu rewa DC hei whetu kanapa hei ārahi i te ahunga whakamua hangarau o te ahumahi.
I tēnei wā, i roto i te umanga whakarewa, kua tīmata te whakawhanake i tētahi hangarau hou mai i te tekau tau atu i 1970. Kua pumau te pewa o te oumu DC, kua kukū te mana, kua tino pai te whakamahinga o te wera, ā, he iti te whakamahinga o te hiko, he iti te haruru whakahaere, ā, he nui te hua.
I tāwāhi, i te tau 1984 i Āwherika ki te Tonga i hanga he oumu ferrochrome waro-teitei 40MVA te kaha. Ko te oumu ferrosilicon 1800-8000kvA, silicon ahumahi, silicomanganese, ferrochrome, oumu wera kohuke DC (irahiko raro kotahi) me te oumu hanga maitai DC o Haina kua eke ki ētahi wheako angitu, i ngā tau tata nei, kua hangaia, kua tukuna ki Haina te oumu DC ki te whakaputa ko:
12500-33000kvA Umu Wera Kohuke Silicon-Manganese DC (4 ngā irahiko)
12500-16500kvA Teitei Silicon DC Mineral Wera Oumu (4 ngā irahiko)
12500kvA Silicon Barium DC Mineral Wera Oven (4 ngā irahiko)
12500kvA Silicon Zirconium DC Mineral Wera Oven (4 ngā irahiko)
10000-16000kw Umu Wera Kohuke Silicon DC Ahumahi (4 ngā irahiko)
9000kw Ferrochrome DC Mineral Wera Oven (4 ngā irahiko)
30000kw Titanium Slag DC Mineral Wera Oumu (1 hiko turanga)
Ko te whanaketanga o ngā oumu rewa DC he tino nekehanga whakamua i roto i te ahunga whakamua hangarau. Ki te whakatauritea ki te oumu wera kohuke AC tuku iho, he mārama ōna painga. Mō te whai huatanga o te pūngao, ka tino pai ake te hurihanga o te oumu rewa DC hei whai huatanga o te pūngao wera. E whakaatu ana ngā tatauranga tūturu he 20% teitei ake te tere whakamahinga pūngao i te oumu tuku iho, e whakaiti ana i te ngaronga pūngao, ā, e whakatairanga ana i te whakaiti i ngā utu whakaputa me te whakapai ake i te whai huatanga ōhanga. I taua wā anō, he tino pumau me te ngāwari te whakahaere o te oumu wera kohuke DC i te wā e whakamahia ana, ā, ka taea e ia te whakahaere tika i ngā āhuatanga tauhohenga i roto i te oumu, kia pai ake ai te kounga o te hua me te pikinga tonu o te whakaputanga.
E ai ki ngā raraunga o nāianei, he pai ake te putanga o te oumu DC me te oumu AC i te oumu AC mēnā ka whakatauritea whānuitia ngā tohu whakaputa, ā, he pai ake te putanga o te oumu DC, te kai hiko me ētahi atu tohu i te oumu AC. Nā te whakaiti i te kai hiko whakarewa me te whakapai ake i te pānga o ngā hua i waenga i ngā tauwehenga mana me ngā hua.
I tēnei wā, ko te whanaketanga o ngā hangarau maha-irahiko o te oumu DC e 4 ngā irahiko, e 6 ngā irahiko me ētahi atu, e whakaata ana i ngā painga kitea o ngā ferroalloy whakarewa oumu kohuke DC, ko te ia o te penapena pūngao me te oumu kohuke nui. Hei tāpiri, ko te whakaurunga o te hangarau atamai ka tino whakapai ake i te taumata aunoa o te oumu whakarewa DC, he watea ake, he pai ake hoki te mahi, kua nui te whai huatanga mō te hanga umanga.
I te wā anō e hōhonu ana te ariā o te tiaki taiao, e awhi ana hoki te oumu rewa DC i te ia o te ao matomato o te wā. E whakaatu ana ngā raraunga e tika ana he tino pai te mahi a te oumu rewa DC i roto i te penapena pūngao me te whakaiti i ngā tukunga, ā, kua tino heke ngā tukunga parahanga, ā, kua whai wāhi te whanaketanga tauwhiro ki tētahi kaha.
I te arotake i te hītori whanaketanga o te oumu rewa DC, kāore e taea te kore e miharo ki te mahi uaua me te mātauranga kua whakapūmautia o ngā kairangahau me ngā miihini. Mai i te pūtake o te ariā tuatahi, ki te whakapai tonu me te arotau i te hangarau, i ia taahiraa o ō rātou werawera me te mātauranga. Hei tauira, i te whakawhanaketanga o te oumu rewa DC, kua angitu te hinonga ki te arotau i ngā tawhā hiko me ngā rauemi me te hanganga o te oumu i muri i ngā whakamātautau me ngā whakapainga maha, kia pai ake ai te tu atu o te tinana oumu i ngā āhuatanga tino kino pēnei i te pāmahana teitei me te pēhanga teitei, ā, i te wa ano, kua tino pai ake te mahi a ngā irahiko me ētahi atu wāhanga matua.
I te tirohanga whakamua, e tūmanakohia ana ka tutuki i te oumu wera kohuke DC ngā putanga hou me ngā whanaketanga nui ake:
Tuatahi, mā te auahatanga hangarau ka whakatairanga i te whai huatanga o te pūngao me te pumau o te oumu rewa DC hei whakapai ake, hei āwhina i ngā umanga ki te whakaiti i ngā utu whakaputa me te whakapai ake i te whakataetae mākete.
Tuarua, ko te whanaketanga o te oumu whakamahana kohuke DC ka whakamahi i te matauranga horihori, te raraunga nui me ētahi atu tikanga hangarau mohio hei whakatutuki i te aroturukitanga wā-tūturu me te whakahaere aunoa i ngā āhuatanga o te oumu rewa, hei whakateretere i te tono o ngā taputapu āwhina mohio, tae atu ki te whakamahine mohio AI, te karetao kanohi mono tuwhera, te karetao hiko hono, te mīhini patu aunoa, te karetao tirotiro, te taputapu whakaahua pāmahana teitei i roto i te oumu, te taputapu whakakore aunoa, te pūnaha maka tonu, me ētahi atu tono taputapu āwhina matatau, hei whakapai ake i te whai huatanga o te whakaputa, hei whakaiti i te whakapaunga pūngao, hei whakapai ake i te kounga hua, me te whakatutuki i te mohio me te matomato o te pūnaha whakaputa.
Hei tāpiritanga, ka whānuitia hoki ngā mara tono o te oumu rewa DC, me te whai wāhi nui anō hoki ki te umanga whakarewa, e tika ana kia whakamahia whānuitia i roto i te umanga matū, rauemi me ētahi atu mara, ka whai wāhi atu ki te ahunga whakamua me te whanaketanga o ētahi atu ahumahi.
Nā te angitu o te whakamahinga o te hiko DC i roto i te oumu wera kohuke kua hua mai he painga nui me ngā whai wāhitanga whanaketanga mō te umanga whakarewa. Mā te auahatanga tonu me te ahunga whakamua hangarau, e whai take ana mātou ki te whakapono ka whai wāhi nui tonu te hiko DC i te heke mai, hei whakatairanga i te whanaketanga tonu me te ahunga whakamua o te hangarau oumu wera kohuke, hei whakapai ake me te whakarato i te wāhi mutunga kore mō te whanaketanga o ngā hua hou, kia puta ai he tirohanga whānui me te whanaketanga pumau o te heke mai i te mara ahumahi.
I roto i te poto, me ōna painga ahurei me ngā tirohanga whānui mō te whanaketanga, ka haere tonu te mahi nui a te oumu wera kohuke DC i roto i te ao ahumahi o te heke mai, ā, ka nui ake āna takoha ki te ahunga whakamua o te ahumahi me te whanaketanga tauwhiro. Kei te tumanako mātou ki ētahi atu auahatanga me ngā putanga hou hei whakatairanga i te hangarau oumu wera kohuke DC ki tētahi taumata hou!
