Isixhobo esikhethekileyo sembuyekezo yesihluzi seHYFCKRL uthotho lweziko learc elintywiliselweyo

Inkcazelo emfutshane:

Isithando somlilo esifakwe emanzini sikwabizwa ngokuba sisithando sombane se-arc okanye isithando sombane esixhathisayo.Esinye isiphelo se-electrode sifakwe kwinqanaba lezinto eziphathekayo, lenze i-arc kwi-layer yezinto kunye nokufudumeza izinto ngokuchasana kwayo.Ihlala isetyenziselwa ukunyibilikisa i-alloys, ukunyibilikisa i-nickel matte, i-matte copper, kunye nokuvelisa i-calcium carbide.Isetyenziswa ikakhulu ekunciphiseni ukunyibilika kwentsimbi, iiarhente zokunciphisa ikhabhoni kunye nezinyibilikisi kunye nezinye izinto ezikrwada.Ivelisa ikakhulu ii-ferroalloys ezifana ne-ferrosilicon, i-ferromanganese, i-ferrochrome, i-ferrotungsten kunye ne-silicon-manganese alloy, eziyimathiriyeli ekrwada yamashishini kwishishini lesinyithi kunye nemathiriyeli ekrwada efana ne-calcium carbide.Isici sayo sokusebenza kukusebenzisa i-carbon okanye i-magnesia refractory imathiriyeli njenge-lining yesithando somlilo, kunye nokusebenzisa i-electrode yegraphite yokuzihlakulela.I-electrode ifakwe kwintlawulo yokusebenza kwe-arc ephantsi kwamanzi, isebenzisa amandla kunye nokukhoyo kwe-arc ukunyibilikisa isinyithi ngokusebenzisa amandla aveliswa yintlawulo kunye nokuchasana kwentlawulo, ukondla ngokulandelelana, ukucofa i-iron slag ngokuqhubekayo, kunye nokusebenza ngokuqhubekayo kombane wemizi-mveliso. eziko.Kwangaxeshanye, iifurnaces ze-calcium carbide kunye ne-yellow phosphorus furnaces nazo zingabalelwa kwii-arc eziphantsi kwamanzi ngenxa yeemeko ezifanayo zokusetyenziswa.

Xa kuthelekiswa nembuyekezo ye-voltage ephezulu, iingenelo zembuyekezo ye-voltage ephantsi zibonakaliswa ikakhulu kule miba ilandelayo ukongeza ekuphuculeni into yamandla:
(1) Ukuphucula izinga lokusetyenziswa kwee-transformers kunye nemigca ephezulu yangoku, kunye nokwandisa amandla okufakelwa okusebenzayo okunyibilikisa.Kwi-arc smelting, ukuveliswa kwamandla asebenzayo kubangelwa ikakhulu yi-arc current.Indawo yembuyekezo iqhutyelwa phambili kwinethiwekhi emfutshane, kwaye inani elikhulu lothungelwano olufutshane luhlaziywa ekuhlaleni.Ukusetyenziswa kwamandla asebenzayo, ukonyusa igalelo lombane wobonelelo lwamandla, ukonyusa imveliso yesiguquli, kunye nokwandisa amandla asebenzayo okunyibilikisa.Amandla okunyibilika kwezinto ngumsebenzi wombane we-electrode kunye nokuchasana okuthe ngqo kwezinto, ezinokuthi zichazwe ngokulula njenge-P = U 2 / Z impahla.Ngenxa yokuphuculwa komthamo womthwalo we-transformer, amandla okufakelwa kwe-transformer kwisithando somlilo ayanda, ukwenzela ukuba kuqondwe ukwanda kwemveliso kunye nokunciphisa ukusetyenziswa.
(2) Imbuyekezo engalinganiyo yokuphucula iimeko zesigaba esomeleleyo nesibuthathaka sezigaba ezithathu.Ekubeni ukulungiswa kwenethiwekhi emfutshane yesigaba sesithathu kunye nomzimba wesithando somlilo kunye nezixhobo zesithando somlilo zihlala zingalingani, ukuhla kwamandla ombane ahlukeneyo kunye namandla ahlukeneyo ezigaba ezintathu kukhokelela kwizigaba ezinamandla nezibuthathaka.ukubunjwa kwesigaba.Uqhagamshelo olunxuseneyo lwenqanaba elinye lwamkelwa ukubuyiswa kwamandla asebenzayo, umthamo wembuyekezo wesigaba ngasinye uhlengahlengiswa ngokubanzi, ukuxinana kwamandla ondoqo wesithando somlilo kunye nokufana kwenzuzo kuyaphuculwa, amandla ombane asebenzayo ee-electrode zamanqanaba amathathu ahambelana, i-electrode voltage ilinganiswe, kwaye i-feed yesigaba sesithathu ilungelelaniswa, iphucula isigaba sesithathu Izigaba ezinamandla kunye nezibuthathaka zezigaba zinokufikelela injongo yokwandisa imveliso kunye nokunciphisa ukusetyenziswa.Ngexesha elifanayo, inokuphucula into engalinganiyo yezigaba ezintathu, ukuphucula indawo yokusebenza yesithando somlilo, kunye nokwandisa ubomi benkonzo yesithando somlilo.
(3) Ukunciphisa i-harmonics ye-high-order, ukunciphisa umonakalo we-harmonics kwisixhobo sonke sokubonelela ngombane, kunye nokunciphisa ilahleko eyongezelelweyo yee-transformers kunye nothungelwano.
(4) Umgangatho wamandla uphuculwe.Ke ngoko, ezinye iiyunithi zithathe amanyathelo embuyekezo yamandla asebenzayo kwisiphelo sombane ophantsi ukusombulula ezi ngxaki zingentla.Imbuyekezo kwi-short-grid end inokuphucula kakhulu amandla ombane we-short-grid end kunye nokunciphisa ukusetyenziswa kwamandla.Isixa esikhulu sokusetyenziswa kwamandla asebenzayo kunye nokungalungelelani kothungelwano olufutshane kwicala le-voltage ephantsi yesiguquli somlilo, kuthathelwa ingqalelo ukuphuculwa okusebenzayo kwezinto zamandla kunye nokuphumeza ukuguqulwa kobugcisa bombane osebenzayo kwimbuyekezo ye-site, ithembekile ngokobugcisa. kwaye ngokuqolileyo, kwaye xa sithetha ngokoqoqosho, igalelo kunye nesiphumo zilungelelana ngokuthe ngqo.Kwicala le-voltage ephantsi ye-arc eziko, amandla asebenzayo kwi-site imbuyekezo iphunyeziwe kwi-short-circuit reactive reactive power kunye nesigaba sesithathu esingalinganiyo isenzeko esinobude obungahambelaniyo bokucwangcisa, nokuba iphucula into yamandla, ifunxa. harmonics, okanye ukwandisa imveliso kunye nokunciphisa ukusetyenziswa.Zonke zineenzuzo ezingenakuthelekiswa nanto zembuyekezo yamandla ombane aphezulu.Nangona kunjalo, ngenxa yenani elikhulu lokutshintsha iteknoloji yokutshintsha imbuyekezo yemveli (efana nokusebenzisa i-AC contactor switching), ixabiso lokutshintsha utshintsho liphezulu, kwaye kwangaxeshanye, ngenxa yendawo yokusebenza enzima, ubomi benkonzo ichaphazeleke kakhulu.Ubomi benkonzo yembuyekezo ye-voltage ephantsi kunye nokutshintshwa kwendabuko kunzima ukudlula unyaka omnye, ngoko kuzisa ukugcinwa okuninzi kwishishini, kwaye ixesha lokubuyisela utyalo-mali lide.Ngenxa yeendleko eziphezulu zokulandela ukugcinwa, izibonelelo ezibanzi azilungile.
