Isithando somlilo sekristalu esisodwa siwuhlobo lwemishini esebenzisa i-high-purity graphite heater ukuze incibilike izinto zokusetshenziswa ze-polycrystalline ezifana namaseli e-photovoltaic endaweni yegesi engavamile, futhi isebenzisa indlela ye-Czochralski ukuze kukhule ikristalu eyodwa engagudluki.Ama-crystal furnaces asetshenziswa kakhulu.Imikhiqizo eminingi efana ne-silicon ye-monocrystalline, i-monocrystalline germanium, ne-monocrystalline gallium arsenide iyimpahla ebalulekile yemboni yezogesi kanye nezinye izimboni zobuchwepheshe obuphezulu.Ngokukhula okuqhubekayo kokuthuthukiswa komnotho wezwe lami, ukusetshenziswa kwezithando zomlilo zekristalu kuzokwanda kakhulu.
Njengenye yamagatsha abalulekile eziko lezimboni, izithando zomlilo zekristalu eyodwa zisebenzisa amandla amaningi.Izindleko zikagesi eziphakeme kanye nokungcoliswa okuphezulu kwe-harmonic kuholela ekuwohlokeni kwekhwalithi yomkhiqizo, okuye kwaba usizi kubasebenzisi abaningi besithando somlilo sekristalu esisodwa.Ukuphendula izidingo eziphuthumayo zokuvikelwa kwemvelo nokonga amandla kwamakhasimende amaningi esithandweni somlilo se-polysilicon emhlabeni wonke, abakhiqizi abaningi benze imizamo nemizamo eminingi emihle.Abantu abaningi bazama ukuvikela isistimu kuma-transients, ama-surges kanye nemikhiqizo yokucindezelwa kwe-harmonic ukwenza amaphrojekthi wokuguqulwa kwezobuchwepheshe ohlelweni lwesithando somlilo se-polysilicon, kodwa isicelo sangempela sibonisa ukuthi ama-harmonic frequencies yesithando somlilo se-polysilicon ikakhulukazi ama-harmonics wesi-5, wesi-7 kanye ne-11 (5 Okuqukethwe kwamanzi okuphezulu kwe-sub-harmonic kudlula i-45%, i-7th harmonic 20%, i-harmonic ye-11 11%, inani eliphelele lokulahlekelwa kwefreyimu lidlula i-49.43%, isici samandla esincane si-0.4570 kuphela, futhi isici samandla esiphezulu si-0.6464 kuphela ).Ngakho-ke, indlela yokuphatha ishayela yamanje yalawa madivayisi ayikwazi ukuzitshwa, futhi umphumela wokonga amandla awugculisi.Okubi nakakhulu ukuthi amandla amanje e-pulse adlula kakhulu uhla lwezinto zikagesi ezithwala umthwalo, futhi kulula ukulimaza ngemva kokusetshenziswa isikhathi eside.Izinga eliphezulu lezingozi lithinta ukusebenza okuvamile kokukhiqizwa kwenkampani, okuholela ekumoshweni kwezinsiza kanye nokucindezeleka kwamakhasimende.
Isethi yemishini yesinxephezelo yesihlungi eklanywe yimi ngalolu hlobo lwemishini ingaxazulula ngempumelelo izinkinga ezingenhla (izindlela ezimbili: uma kokubili ukulawulwa kwe-harmonic kanye nesinxephezelo samandla asebenzayo sidingeka ukuze kudlule izinga, sisebenzisa i-harmonic control loop + i-reactive power adjustment Loop; ukusebenza okuvamile kudinga kuphela isinxephezelo samandla asebenzayo, futhi isici samandla sidlula isicaciso. Sisebenzisa isikimu sesinxephezelo samandla asebenzayo sokucindezela kwe-harmonic).Ayikwazi ukulawula ama-harmonics kuphela, kodwa futhi inxephezela imithwalo esebenzayo.Ingakwazi ukuqeda ngokuphelele ukungcoliswa kwemvelo kwe-harmonic futhi ithuthukise isici samandla.Izinzuzo zezomnotho ezibalulekile.Izindleko zokusebenza ngokuvamile zingabuyiselwa phakathi nezinyanga ezi-3 kuya kwezingu-5.
isici esiyinhloko:
1. Okwesofthiwe yesistimu yekhasimende*, i-harmonics yesici esicacile, njenge: 5th, 7th, 11th, 13th, njll. Umphumela wokuhlunga usobala.
2. I-Harmonics ingaphathwa, isinxephezelo asisebenzi
3. Ngemva kokuthi idivayisi yokuhlunga isiqalile ukusebenza, ingathuthukisa kakhulu ikhwalithi yamandla, ithuthukise umthelela wamanje obangelwa umthwalo womthelela, inciphise ukushintshashintsha kwamandla kagesi, icindezele ukucwayiza kwamandla kagesi, ithuthukise ukwethembeka kwamandla kagesi, futhi ithuthukise ikhwalithi kagesi.Isici samandla singakhushulwa sibe ngaphezu kuka-0.96, futhi ukunciphisa ukulahlekelwa komugqa womsebenzisi kungathuthukisa ukusebenza kahle kokuthwala umthwalo we-transformer yokusabalalisa, futhi izinzuzo zezomnotho zisobala.
4. Ukushintsha kwe-vacuum yokusebenza kusetshenziselwa ukushintsha iluphu yesihlungi ngasinye.Isistimu yokulawula okuzenzakalelayo inemininingwane eminingi futhi imisebenzi yokulungisa iphelele, njengokuvikelwa kwamanje, ukuvikelwa kwe-voltage engaphezu kwamandla, ukuvikelwa kwamanje, njll. Umsebenzi wangempela uthembekile futhi ukusebenza kulula.
Izinzuzo Zokubusa Okuvumelanayo:
1. Ngemva kokufaka imishini yokulawula i-pulse yamanje, i-harmonic current ingancishiswa ngokunengqondo, umthamo ozwakalayo we-transformer ungakhuphuka, umthamo ohambisanayo wokuthwala ikhebula nawo uyanda, futhi ukutshalwa kwezimali kwephrojekthi okudingekayo ekukhuliseni kuyancipha.
2. Ngemva kokufaka imishini yokulawula i-pulse yamanje, ukulahlekelwa kwe-transformer kungancishiswa ngokuphumelelayo, inkomba yokusebenza ephephile ye-transformer ingathuthukiswa, futhi inhloso yokulondoloza amandla nokunciphisa ukukhishwa kungafinyelelwa.
Izixazululo ongakhetha kuzo:
uhlelo 1
Ngokuphathwa okumaphakathi (okulungele izithando zomlilo eziningi ezabelana nge-transformer eyodwa futhi zisebenze ngesikhathi esisodwa, igumbi lokusabalalisa amandla lifakwe idivayisi yesinxephezelo sesihlungi)
1. Sebenzisa igatsha lokulawula i-harmonic (5, 7, 11 filter) + igatsha lokulawula amandla asebenzayo.Ngemuva kokuthi idivayisi yesinxephezelo sesihlungi isiqalile ukusebenza, isilawuli se-harmonic nesinxephezelo samandla asebenzayo wesistimu yokuphakelwa kwamandla kuhlangabezana nezimfuneko.
2. Yamukela isihlungi esisebenzayo (susa ukuhleleka kwama-harmonics ashukumisayo) kanye nesekethe yegatsha le-harmonic countermeasure (5, 7, 11 isihlungi se-oda) # + isifunda segatsha sokulungiswa okungavumelekile, futhi ngemva kokunikeza imishini yesinxephezelo yesihlungi, faka isicelo sesinxephezelo esingavumelekile uhlelo lokuphakela amandla.
3. Sebenzisa izisetshenziswa zesinxephezelo ezingavumelekile (5.5%, 6% ama-reactors) ukuze ucindezele ama-harmonics, futhi ngemva kokufaka izisetshenziswa zesinxephezelo zesihlungi, udinga isistimu yokuphakela amandla ukwenza isinxephezelo esingavumelekile.
Isimo 2
Ukuphatha endaweni (setha iphaneli yesinxephezelo sesihlungi eduze kwephaneli yokuphakela amandla yesithando somlilo se-silicon ye-monocrystalline)
1. Igatsha lokulawula i-Harmonic (5, 7, 11 filtering) liyamukelwa, futhi amandla asebenzayo e-harmonic afinyelela izinga ngemva kokufaka.
2. Khetha i-reactor evikelayo nesihlungi samandla kagesi we-dual-loop (isihlungi sesi-5 nesesi-7) ukuze ugweme ukuthonyana, futhi ukushaya kwenhliziyo ngemva kokuxhumeka akudluli ukucaciswa.
