Iyo imwechete crystal furnace imhando yemidziyo inoshandisa yakakwirira-kuchena graphite heater kunyungudutsa polycrystalline mbishi zvinhu zvakaita semafotovoltaic masero munzvimbo isingawanzo gasi, uye inoshandisa iyo Czochralski nzira yekukura dislocation-isina single crystal.Single crystal furnaces inowanzoshandiswa.Zvigadzirwa zvakawanda zvakadai semonocrystalline silicon, monocrystalline germanium, uye monocrystalline gallium arsenide zvakakosha zviwanikwa zveindasitiri yemagetsi uye mamwe maindasitiri epamusoro-soro.Nekukura kunoramba kuchienderera mberi kwekusimudzira hupfumi hwenyika yangu, kushandiswa kwemafuremu ekristaro imwe chete kuchawedzera kuwedzera.
Seimwe yematavi akakosha echoto cheindasitiri, simbi imwe chete yekristaro inoshandisa simba rakawanda.Mutengo wemagetsi wakakwira uye kusvibiswa kwakanyanya kunotungamira mukuderedzwa kwemhando yechigadzirwa, izvo zvave kurwadza kwemoyo kune vakawanda vashandisi vekristaro imwechete.Mukupindura kune zvinodiwa nekukurumidza zvekuchengetedzwa kwezvakatipoteredza uye kuchengetedza kwesimba kwevatengi vepolysilicon choto chemoto pasi rese, vagadziri vazhinji vakaita zvakawanda zvakanaka kuedza uye kuedza.Vanhu vazhinji vanoedza kuchengetedza sisitimu kubva kune inodarika, masurges uye harmonic kudzvinyirira zvigadzirwa kuita tekinoroji shanduko mapurojekiti pane polysilicon choto system, asi iyo chaiyo application inoratidza kuti harmonic frequencies yepolysilicon choto inonyanya 5th, 7th uye 11th harmonics (5). Iyo yakanyanya mvura yemukati meiyo sub-harmonic inopfuura 45%, iyo 7th harmonic 20%, iyo 11th harmonic 11%, iyo yakazara furemu kurasikirwa mwero inopfuura 49.43%, iyo shoma simba chinhu ingori 0.4570, uye iyo yakanyanya simba chinhu ingori 0.6464 ).Naizvozvo, iyo pulse ikozvino manejimendi nzira yezvishandiso izvi haigone kufuratirwa, uye simba rekuchengetedza simba harigutsi.Chinonyanya kuoma ndechekuti simba remagetsi rinopfuura zvakanyanya kutakura mutoro wezvigadzirwa zvemagetsi, uye zviri nyore kukuvadza mushure mekushandisa kwenguva refu.Kuwanda kwetsaona kunokanganisa kushanda kwamazuva ose kwekugadzirwa kwekambani, zvichikonzera kutambisa zviwanikwa uye kushushikana kwevatengi.
Seti yemidziyo yekubhadhara sefa yakagadziridzwa neni yemhando iyi yemidziyo inogona kunyatsogadzirisa matambudziko ari pamusoro (nzira mbiri: kana zvese zviri zviviri harmonic control uye reactive simba muripo zvichidikanwa kudarika mwero, tinoshandisa harmonic control loop + reactive simba rekugadzirisa Loop; zvakajairika kushanda chete kunoda reactive simba muripo, uye simba chinhu chinodarika yakatarwa Isu tinoshandisa harmonic kudzvinyirira reactive simba muripo).Haikwanise kudzora ma harmonics chete, asiwo kubhadhara mitoro inoshanda.Inogona kubvisa zvachose harmonic kusvibiswa kwezvakatipoteredza uye kuvandudza simba chinhu.Kubatsira kwakakosha kwehupfumi.Mari yekushandisa inogona kudzoserwa mukati memwedzi mitatu kusvika ku5.
main feature:
1. Kune mutengi system software *, yakajeka hunhu harmonics, akadai: 5th, 7th, 11th, 13th, etc. Kusefa mhedzisiro iri pachena.
2. Harmonics inogona kutarisirwa, muripo haushande
3. Mushure mekunge mudziyo wesefa waiswa mukushanda, unogona kuvandudza zvakanyanya kunaka kwesimba, kuvandudza iko zvino kukonzeresa kukonzeresa mutoro, kuderedza kushanduka kwemagetsi, kudzvanya voltage flicker, kunatsiridza kuvimbika kwevoltage, uye kunatsiridza kunaka kwemagetsi.Chinhu chesimba chinogona kuwedzerwa kusvika kune 0.96, uye kuderedzwa kwekurasikirwa kwemutsara wevashandisi kunogona kuvandudza kutakura-kutakura kushanda kweshanduro yekugovera, uye hupfumi hwehupfumi huri pachena.
4. Performance vacuum switches inoshandiswa kuchinja imwe neimwe sefa loop.Iyo otomatiki control system inotsanangurwa uye mabasa ekugadzirisa akakwana, akadai seanopfuura-ikozvino kuchengetedzwa, over-voltage kuchengetedzwa, over-current protection, etc. Iko kushanda chaiko kwakavimbika uye kushanda kuri nyore.
Zvakanakira Harmonic Governance:
1. Mushure mekuisa iyo pulse current control equipment, harmonic yazvino inogona kuderedzwa zvine musoro, inonzwisisika volume ye transformer inogona kuwedzerwa, iyo inofananidzwa netambo inotakura simba inowedzerwawo, uye mari yeprojekiti inodiwa pakuwedzera inoderedzwa.
2. Mushure mekuisa pulse current control equipment, kurasikirwa kweshanduro kunogona kuderedzwa zvakanaka, iyo yakachengeteka yekushanda index ye transformer inogona kuvandudzwa, uye chinangwa chekuchengetedza simba uye kuderedzwa kwekubudisa kunogona kuwanikwa.
Mhinduro dzekusarudza kubva:
chirongwa 1
Kune yepakati manejimendi (inokodzera mavira akawanda anogovera imwe transformer uye inoshanda panguva imwe chete, imba yekugovera magetsi ine sefa yekuripa mudziyo)
1. Shandisa harmonic control bazi (5, 7, 11 sefa) + reactive simba regulation bazi.Mushure mesefa yekubhadhara mudziyo waiswa mukushanda, iyo harmonic control uye reactive simba muripo weiyo magetsi system inosangana nezvinodiwa.
2. Adopt inoshanda sefa (bvisa kurongeka kwesimba rinosimba) uye harmonic countermeasure bazi redunhu (5, 7, 11 odha sefa) # + isingashande kugadzirisa bazi redunhu, uye mushure mekupa kune sefa muripo wemidziyo, isa mberi Chikumbiro chemuripo usina kukodzera iyo magetsi system.
3. Shandisa midziyo yekubhadhara isingabvumirwe (5.5%, 6% reactors) kudzvanyirira maharmonics, uye mushure mekuisa mafirita muripo wemidziyo, inoda kuti magetsi emagetsi aite muripo usiriwo.
Scenario 2
Pa-saiti manejimendi (seta sefa yekubhadhara pani padivi pemagetsi emagetsi eiyo monocrystalline silicon furnace)
1. Harmonic control bazi (5, 7, 11 kusefa) inogamuchirwa, uye iyo harmonic reactive simba inosvika pachiyero mushure mekupinda.
2. Sarudza inodzivirira reactor uye filter dual-loop power supply (5th uye 7th filter) kuti udzivise kupindirana, uye pulse ikozvino mushure mekubatanidza haipfuure tsanangudzo.
