Imyitwarire yatewe numuyoboro mugufi w'itanura rinini kandi rito ryarengewe na arc bingana na 70% bya reaction ya feri yo gushyushya.Itanura rya arc itanura ryumuyoboro mugufi bivuga ijambo rusange muburyo butandukanye bwumuvuduko muke hamwe nuyobora amashanyarazi menshi kuva mumatsinda mato asohokera kumpera yumuriro wamashanyarazi kugeza kumashanyarazi.Nubwo uburebure bwurushundura rugufi rwamashyiga ya arc yarengewe ntabwo arinini, résistoriste ngufi na reaction bigira ingaruka zikomeye kubikoresho by'itanura rya arc ryarengewe.Bitewe nuburyo bugoye, ikigezweho kinyuramo kigera ku bihumbi magana amperes.Kuberako agaciro k'umuzunguruko mugufi muri rusange inshuro 3 kugeza kuri 6 zingana na rezistor, reaction ya short-circuit ahanini igena imikorere, imbaraga zingufu hamwe ningufu zikoreshwa mumatanura ya arc yarengewe.
Uburyo busanzwe bwo kwishyurwa nintoki nuguhuza urukurikirane rwindishyi za banki na bisi yumuriro mwinshi kuruhande rwibanze rwa transformateur arc itanura, ni ukuvuga indishyi zikabije.Kubera ko ingaruka zindishyi zishobora kungukirwa gusa numurongo mbere yo kugera no kuruhande rwa gride ya sisitemu yo gutanga amashanyarazi, sisitemu yo gutanga amashanyarazi irashobora kuzuza ibisabwa bijyanye ningufu zumurongo wumurongo, ariko ntishobora kwishyura indangururamajwi. , umuyoboro mugufi, na electrode y'itanura rya kirombe.Imbaraga zifatika zumwanya wa kabiri-w-voltage ntoya hamwe n’umuzunguruko mwinshi, ni ukuvuga ko ibikoresho bidashobora kungukirwa no kongera umusaruro w’ibicuruzwa byo mu itanura ry’amabuye y'agaciro no kugabanuka kw'ikoreshwa ry'amashanyarazi no gukoresha ibirombe.
Mubisanzwe, gushyira hamwe ingamba zo guhuza hamwe no guhuza ibitekerezo byahujwe birashobora guhurizwa hamwe kugirango habeho ingamba zo guhuza ibiciro.Kubijyanye nisoko yimitwaro ifite imbaraga nini (nkitanura ryinshyi, inverter, nibindi), ingamba zo guhuza ibikorwa zirashobora gukoreshwa mugushiraho ingamba zo guhangana, kugirango ugabanye imiyoboro ihujwe muri gride.Ugereranije imbaraga nto kandi zitatanye zidafite umurongo zirashobora gucungwa kimwe muri bisi.Hongyan APF ikora muyunguruzi irashobora gukoreshwa, kandi kugenzura guhuza nabyo birashobora gukoreshwa.
Itanura rya arc yarengewe ningufu nyinshi ikoresha itanura ryamashanyarazi hamwe nibiranga itanura ryamashanyarazi arc.Impamvu zingufu zigenwa na arc hamwe na R kurwanya R mu itanura nagaciro kokurwanya R hamwe nigikorwa cya X mumashanyarazi (harimo transformateur, inshundura zumuzunguruko mugufi, impeta zegeranya, urwasaya ruyobora na electrode).
cosφ =.Kurwanya R bifitanye isano nuburemere bugezweho bwibice bigufi byumuzunguruko mugihe cyibikorwa, kandi impinduka ntabwo ari nini, ariko kurwanya R ni ikintu cyingenzi muguhitamo imbaraga zamashyiga ya arc yarohamye mugihe cyibikorwa. .
Kubera ko itanura rya arc ryarohamye rifite imbaraga zo guhangana n’andi matanura yo gushonga amashanyarazi, imbaraga zayo nazo ziragabanuka uko bikwiye.Usibye umuvuduko w'amashanyarazi usanzwe w'itanura rito rito rigeze hejuru ya 0.9, umuvuduko w'amashanyarazi usanzwe w'itanura rinini rifite ubushobozi buri hejuru ya 10000KVA byose biri munsi ya 0.9, kandi uko ubushobozi bw'itanura rya kirombe bugenda bugabanuka. ikintu.Ibi biterwa nuburemere bunini bwa inductive ya transformateur ya arc itanura yarengeje umwanya munini, umwanya muremure umuyoboro mugufi, hamwe nuburemere bwimyanda yinjijwe mumatanura, ibyo bikaba byongera reaction yumurongo mugufi, bityo bikagabanya ibintu byingufu. y'itanura rya arc.
Mu rwego rwo kugabanya imikoreshereze y’amashanyarazi no kuzamura ireme rya sisitemu yo gutanga amashanyarazi, Ikigo gishinzwe gutanga amashanyarazi giteganya ko ingufu z’isosiyete ikora amashanyarazi zigomba kuba hafi 0.9, bitabaye ibyo isosiyete ikora amashanyarazi izahanishwa ibihano bikomeye.Byongeye kandi, imbaraga nke nazo zizagabanya voltage yinjira kumurongo winjira mumatara ya arc yarengewe, bizangiza calcium karbide smelter.Kubwibyo, kuri ubu, amashyiga manini manini yarohamye mu gihugu ndetse no hanze yacyo akeneye gushyiraho ibikoresho byindishyi zamashanyarazi kugirango atezimbere ingufu zamashyiga ya arc.
Indishyi nkeya ya filteri
1. Ihame
Indishyi nke za voltage nigikoresho cyindishyi zidakoreshwa zikoresha tekinoroji igezweho igezweho hamwe nikoranabuhanga rito rigufi kugirango rihuze imbaraga nini, nini-nini cyane ya ultra-low voltage yamashanyarazi kuruhande rwa kabiri rwitanura rya kirombe.Iki gikoresho ntabwo aricyo gikorwa cyiza gusa cyihame ryindishyi zamashanyarazi, ariko kandi kirashobora gutuma ibintu byingufu z itanura ryibirombe bikora ku giciro cyo hejuru, bikagabanya imikoreshereze yumuriro wumurongo mugufi hamwe nuruhande rwibanze, hanyuma ukuraho icya gatatu, icya gatanu n'icya karindwi.Kuringaniza ibyiciro bitatu bisohoka imbaraga kugirango wongere ubushobozi bwa transformateur.Icyibandwaho kugenzura ni ukugabanya urwego rutaringaniye rwingufu zibyiciro bitatu no kugera kubice bitatu bingana.Kwagura inkono ya clamp, kwibanda ku bushyuhe, kongera ubushyuhe hejuru y’itanura, no kwihutisha kubyitwaramo, kugirango ugere ku ntego yo kuzamura ubuziranenge bwibicuruzwa, kugabanya ibicuruzwa, no kongera umusaruro.
Iri koranabuhanga rikoresha tekinoroji gakondo ikuze ku mbuga ku gice cya kabiri cy’amashanyarazi make ku itanura rya kirombe.Imbaraga zidasanzwe zitangwa na capacitor zinyura kumurongo mugufi, igice cyacyo kikaba cyinjijwe na transformateur ya feri ya minisiteri ivuye muri sisitemu, ikindi gice kikaba cyishyura imbaraga zidasanzwe za transformateur ya feri, umuyoboro mugufi na electrode.Gutakaza ingufu byongera imbaraga zinjiza mumatanura.Muri icyo gihe, indishyi zitandukanijwe n’icyiciro zemezwa kugira ngo ingufu zikora kuri electrode zicyiciro cya gatatu cy’itanura rya arc zirengewe zingana, kugirango tunoze ibintu byamashanyarazi, bigabanye ubusumbane bwingufu zibyiciro bitatu, kandi bitezimbere umusaruro indangagaciro.
2. Gukoresha indishyi nke za voltage
Mu myaka yashize, kubera iterambere gahoro gahoro tekinoroji y’indishyi nkeya, gahunda yo gushushanya yarushijeho kuba nziza, kandi ingano yagabanutse cyane.Abakora itanura rya arc barengeje kandi bamenye imikorere yayo mugutezimbere inyungu zubukungu bwitanura rya arc.Ibikoresho by'indishyi nkeya byakoreshejwe cyane muri Transmerged arc itanura.
Ibisubizo byo guhitamo muri:
gahunda 1
Koresha indangururamajwi nyinshi (iyi scenario nindishyi zisanzwe, ariko ingaruka nyayo ntabwo yujuje ibyashizweho).
Urugero rwa 2
Kuruhande rwa voltage nkeya, dinamike ibyiciro bitatu byindishyi zindishyi zungururwa zemewe.Igikoresho cyo kuyungurura kimaze gushyirwa mubikorwa, imbaraga zikora kuri electrode yibyiciro bitatu byamashyiga ya arc yarengewe iringaniza, kugirango tunonosore ingufu, kugabanya ubusumbane bwimbaraga zibyiciro bitatu, no kunoza igipimo cyibikorwa.
