Idivayisi yesinxephezelo yesihlungi esikhethekile yochungechunge lwe-HYFCKRL lwesithando somlilo esingaphansi kwamanzi
incazelo yomkhiqizo
Izinhlobo eziyinhloko kanye nokusetshenziswa kwezithando ze-arc ezingaphansi kwamanzi
Isithando somlilo se-arc esingaphansi kwamanzi siyisithando somlilo sikagesi sezimboni esisebenzisa amandla amaningi.Ikakhulukazi iqukethe igobolondo lesithando somlilo, ikhava yesithando somlilo, ulayini lwesithando somlilo, inetha elifushane, uhlelo lokupholisa amanzi, isistimu yokukhipha intuthu kanye nohlelo lokususa uthuli, igobolondo lokucindezela i-electrode, i-electrode pressing and lifting system, uhlelo lokulayisha nokuthulula, igripper, burner, i-hydraulic system ecwilisiwe. i-arc furnace transformer kanye nemishini ehlukahlukene kagesi
Ngokwezici zesakhiwo nezici zokusebenza zesithando somlilo esingaphansi kwamanzi, i-70% yokusabela kwesistimu yesithando somlilo esingaphansi kwamanzi kukhiqizwa uhlelo olufushane lwenethiwekhi, futhi ukulahlekelwa kwesistimu yesithando somlilo se-arc kuboniswe esithombeni esingezansi.
Uma kuqhathaniswa nesinxephezelo samandla kagesi aphezulu, izinzuzo zesinxephezelo se-low-voltage zibonakala kakhulu kulezi zici ezilandelayo ngaphezu kokuthuthukisa isici samandla:
(1) Thuthukisa izinga lokusebenzisa ama-transformer kanye nemigqa yamanje ephezulu, futhi wandise amandla okufaka asebenzayo okuncibilikisa.Ngokuncibilikisa i-arc, ukukhiqizwa kwamandla asebenzayo kubangelwa ikakhulukazi i-arc current.Iphuzu lesinxephezelo liyiswa phambili kunethiwekhi emfushane, futhi inani elikhulu lamanethiwekhi amafushane linxeshezelwa endaweni.Ukusetshenziswa kwamandla okusebenzayo, khulisa i-voltage yokufaka yokuphakelwa kwamandla, kwandise ukuphuma kwe-transformer, futhi kwandise amandla okufaka asebenzayo okuncibilikisa.Amandla ancibilika wezinto ezibonakalayo ngumsebenzi we-electrode voltage kanye nokumelana okuthile kwezinto, okungase kuvezwe kalula njenge-P = U 2 / Z impahla.Ngenxa yokuthuthukiswa komthamo womthwalo we-transformer, amandla okufaka we-transformer esithandweni ayanda, ukuze kubonakale ukwanda kokukhiqiza nokunciphisa ukusetshenziswa.
(2) Isinxephezelo esingalingani sokuthuthukisa izimo zesigaba esiqinile nesibuthakathaka sezigaba ezintathu.Njengoba ukuhlelwa kwenethiwekhi emfushane yesigaba sesithathu kanye nomzimba wesithando somlilo nezinto zomlilo zihlala zingalingani, ukwehla kwe-voltage ehlukene namandla ahlukene ezigaba ezintathu kuholela ezigabeni eziqinile nezibuthakathaka.ukwakheka kwesigaba.Ukuxhumeka okuhambisanayo kwesigaba esisodwa kwamukelwa ukuze kunxeshezelwe amandla asebenzayo, amandla okunxeshezelwa kwesigaba ngasinye alungiswa ngokuphelele, ukuminyana kwamandla omgogodla wesithando somlilo kanye nokufana kwenzuzo kuyathuthukiswa, i-voltage esebenzayo yokusebenza yama-electrode ezigaba ezintathu iyahambisana, i-electrode voltage ilinganisela, futhi okuphakelayo kwesigaba sesithathu kulinganiselwe, ukuthuthukisa isigaba sesithathu Izigaba eziqinile nezibuthakathaka zezigaba zingafinyelela umgomo wokwandisa ukukhiqiza nokunciphisa ukusetshenziswa.Ngesikhathi esifanayo, ingakwazi ukuthuthukisa into engalinganiselwe yezigaba ezintathu, ithuthukise indawo yokusebenza yesithando somlilo, futhi yandise impilo yesevisi yesithando somlilo.
(3) Yehlisa i-harmonics ye-oda eliphezulu, yehlise ukulimala kwama-harmonics kuyo yonke imishini yokuphakelwa kwamandla, futhi yehlise ukulahleka okwengeziwe kwama-transformer namanethiwekhi.
(4) Ikhwalithi yamandla isithuthukisiwe.Ngakho-ke, amanye amayunithi athathe izinyathelo zokunxeshezelwa kwamandla asebenzayo ekugcineni kwe-voltage ephansi ukuxazulula izinkinga ezingenhla.Isinxephezelo ekugcineni kwegridi emfushane singathuthukisa kakhulu isici samandla esiphetho segridi emfushane futhi sinciphise ukusetshenziswa kwamandla.Inani elikhulu lokusebenzisa amandla asebenzayo kanye nokungalingani kwenethiwekhi emfushane ohlangothini lwe-voltage ephansi ye-transformer yesithando somlilo, kucatshangelwa ukuthuthukiswa okuphumelelayo kwesici samandla nokusebenzisa ukuguqulwa kobuchwepheshe kwesinxephezelo samandla asebenzayo esizeni, sithembeke ngokobuchwepheshe. futhi okufakwayo nokuphumayo kuhambisana ngokuqondile, nokukhuluma ngokomnotho okuvuthiwe.Ohlangothini lwe-voltage ephansi yesithando somlilo se-arc esingaphansi kwamanzi, isinxephezelo samandla asebenzayo esizeni siyasetshenziswa ekusetshenzisweni kwamandla asebenzayo esekethe emfishane kanye nesenzakalo esingalingani sezigaba ezintathu esinobude obungahambelani besakhiwo, noma ngabe sithuthukisa isici samandla, siyamunca. ama-harmonics, noma ukwandisa ukukhiqizwa kanye nokunciphisa ukusetshenziswa.Zonke zinezinzuzo ezingenakuqhathaniswa zesinxephezelo samandla kagesi aphezulu.Kodwa-ke, ngenxa yenani elikhulu lokushintshwa koshintsho kubuchwepheshe bokushintsha isinxephezelo sendabuko (njengokusebenzisa i-AC contactor switching), izindleko zokushintsha ukushintsha ziphezulu, futhi ngesikhathi esifanayo, ngenxa yemvelo yokusebenza enokhahlo, impilo yesevisi kuthinteke kakhulu.Impilo yesevisi yesinxephezelo se-low-voltage ngokushintsha kwendabuko kunzima ukudlula unyaka owodwa, ngakho-ke kuletha ukunakekelwa okuningi ebhizinisini, futhi isikhathi sokubuyisela utshalomali siyandiswa.Ngenxa yezindleko zokulungisa ezilandelwayo eziphezulu, izinzuzo eziphelele azimihle.
imodeli yomkhiqizo
Imingcele Yezobuchwepheshe
● Izigaba ezintathu zinxeshezelwa ngokuhlukene ukuze kuncishiswe ukungalingani kwezigaba ezintathu futhi kukhuliswe ngempumelelo ukukhiqiza nokunciphisa ukusetshenziswa.Thuthukisa kakhulu ukwehla kwamandla kagesi kanye nokucindezelwa kwe-flicker 3rd, 5th, 7th ukungcoliswa kwe-harmonic futhi uqaphele ukushintsha kwamahhala nganoma yisiphi isikhathi
●Ukuthembeka kokushintsha kuphezulu, futhi izikhathi zokushintsha zokushintsha ngaphandle kokwehluleka zingafinyelela izikhathi eziyizigidi ezimbalwa.Kuyizikhathi eziningi zokuphila kwamaswishi ajwayelekile.Ngenxa yokushintshwa kwe-vacuum vacuum yamanje ephezulu, ukumelana komthelela kuhle, futhi kungafinyelela izikhathi eziningi ngaphezu komthelela wamanje ngaphandle kokulimala.Ayikho i-inrush current uma ifakwa, ayikho overvoltage uma inqanyulwa.
●Ukuthembeka okuphezulu, ukunganakeki nokungagadiwe
●Idizayini ethuthukisiwe yokuvikela i-non-fast-fuse igwema ukulimala kwama-capacitor nezixhumi ze-vacuum ngezinga elikhulu kakhulu.Thuthukisa ngokuphawulekayo izinga lokusetshenziswa kwesistimu yokuphakela amandla.
