Umphakeli wemishini esekela i-frequency converter ukukhumbuza ukuthi i-reactor efakwe ohlangothini oluphumayo lwesiguquli semvamisa ukuze sithuthukise isici samandla futhi sicindezele i-harmonic current singanciphisa umsindo nokudlidliza kwemoto. Uma ukuxhumana phakathi kwe-frequency converter kanye nenjini kukude, kungacindezela ukukhuphuka kwezintambo.
Izinketho ezilandelayo zingangezwa ohlangothini lokufakwayo lwesiguquli sefrikhwensi:
1) I-InputReactor iyi-reactor yokokufaka engacindezela ama-harmonic currents, ithuthukise isici samandla, futhi inciphise umthelela wevoltheji yokukhuphuka kanye neyamanje kusekethe yokufaka kusiguquli sefrikhwensi, kanye nokwenza buthaka umthelela wokungalingani kwamandla kagesi. Ngokuvamile, i-reactor yomugqa kufanele yengezwe.
2) Isihlungi se-EMC sokufaka sisetshenziselwa ukunciphisa nokucindezela ukuphazamiseka kwe-electromagnetic okukhiqizwa isiguquli sefrikhwensi. Kunezinhlobo ezimbili zezihlungi ze-EMC, izihlungi ze-A-grade kanye ne-B-grade. Izihlungi zezinga le-EMCA zisetshenziswa esigabeni sesibili sezinhlelo zokusebenza zezimboni futhi zihlangabezana nezinga lezinga le-EN50011A. Izihlungi zezinga le-EMCB zivame ukusetshenziswa esigabeni sokuqala sezinhlelo zokusebenza, okuyizinhlelo zokusebenza ezivamile nezilula zezimboni, futhi zihlangabezana nezinga lezinga le-EN50011B.
Kunezinketho ezimbalwa ezitholakalayo ohlangothini lokuphumayo lwesiguquli sefrikhwensi, okuhlanganisa:
1) I-reactor ephumayo: Uma ubude bekhebula eliphumayo elisuka kusiguquli sefrikhwensi liya enjinini lidlula inani elishiwo lomkhiqizo, i-reactor ephumayo kufanele yengezwe ukuze kunxeshezelwe imiphumela yokushaja nokukhipha amandla okuhlanganisa ngesikhathi sokusebenza kwekhebula ende yenjini, ukuze kugwenywe ukudlula ngokweqile kwesiguquli sefrikhwensi. Kunezinhlobo ezimbili zama-reactor okukhiphayo. Olunye uhlobo i-iron core reactor, esetshenziswa lapho imvamisa yenkampani yenethiwekhi yesiguquli sefrikhwensi ingaphansi kuka-3KHZ. Olunye uhlobo lwe-reactor ephumayo uhlobo lwe-ferrite, olusetshenziswa lapho imvamisa yenkampani yenethiwekhi yesiguquli sefrikhwensi ingaphansi kuka-6KHZ. Inhloso yokwengeza i-rector ephumayo kutheminali yokukhiphayo yesiguquli sefrikhwensi ukukhulisa ibanga phakathi kwesiguquli sefrikhwensi kanye nenjini. I-reactor ephumayo ingacindezela ngempumelelo i-voltage ephezulu esheshayo ekhiqizwe ukushintsha kwe-IGBT yesiguquli sefrikhwensi, inciphise imiphumela emibi yale volthi ekufakeni ikhebula kanye nenjini. Ngesikhathi esifanayo, ukuze kwandiswe ibanga phakathi kwesiguquli se-frequency kanye ne-motor, ikhebula lingaqiniswa ngokufanele ukuze kwandiswe amandla okugxilisa ikhebula, futhi izintambo ezingavikelekile kufanele zikhethwe ngangokunokwenzeka.
2) Imiphumela ye-Outputdv/dtfilter dv/dt reactors. Injongo yokukhipha ama-dv/dt ama-reactors ukukhawulela izinga lokukhuphuka kwe-voltage ephumayo yesiguquli sefrikhwensi ukuze kuqinisekiswe ukugqunywa okuvamile kwenjini.
3) Izihlungi ze-Sinusoidal izihlungi ze-sine wave ezicishe zilingane ne-voltage ephumayo kanye nezamanje yesiguquli semvamisa ukuya kumagagasi e-sine, ezinciphisa i-motor harmonic yesizinda sokushintsha i-coefficient kanye ne-motor insulation pressure.
Ukubamba okungavamile kwama-reactor ochungechunge
Ama-reactors ochungechunge lwe-Capacitor ngokuvamile athatha i-epoxy glass fiber multi encapsulated parallel structures. Ngokwezici zendawo yokufaka, ukupakishwa okuqondile kwezigaba ezintathu, okuvundlile kwezigaba ezintathu "△" kanye nezigaba ezintathu ezivundlile "-" kuyamukelwa.
Izehlakalo eziningi zokusebenza kwe-reactor yochungechunge zenzeke ezindaweni ezingaphansi esifundeni esiseningizimu, lapho ungqimba lwangaphandle lwe-insulation luye lwaqhekeka, futhi ezimweni ezimbi kakhulu, luthinte ukusebenza okuphephile Ngaphansi kwenhlangano yokulawulwa komoya, umkhiqizi nomnyango wokuphatha ukusebenza wenze ukuhlaziya okuningiliziwe Ngaphansi kwenhlangano yokuthunyelwa kwenethiwekhi, umenzi kanye nomnyango wokuphatha ukusebenza benze ukuhlaziya okuningiliziwe. Ngokuqhathanisa izimo zokusebenza ezihlukene kanye nezizathu zesimo sezulu, kwatholakala ukuthi ngenxa yokuthi ibhange le-capacitor lalisebenza ngomthwalo olinganiselwe, ukusebenza kwamanje kwakukhulu, futhi umthamo wamanje ekusebenzeni okuvamile wawufika ku-1000A. Ngaphansi kwesenzo samanje esikhulu kangaka, izinga lokushisa lokusebenza le-reactor yochungechunge lenyuke lasondela ku-100 ℃. Uma bekunemvula ngesikhathi uphuma emsebenzini, izinga lokushisa le-reactor surface lehla ngokushesha, futhi ukuguqulwa kokwanda okushisayo kanye nokufinyela okubandayo ngesikhathi esifushane kwakuyisizathu esiyinhloko sokuqhekeka kwendawo ye-reactor yochungechunge Ngakho-ke, ezidingweni zomsebenzi, ukulungisa iphutha lenethiwekhi kudinga abasebenzi abasebenza esizeni ukuze banciphise izinguquko kwimodi yokusebenza yama-capacitor ngesikhathi sokushintsha kwesimo sezulu kungazelelwe.
Kube nezigameko zokushisisa kwama-reactor ochungechunge futhi abambe umlilo ohlelweni. Ukuhlaziywa kwesizathu kubonisa ukuthi ibhange le-capacitor lisebenza ngomthwalo ophezulu wamanje, futhi lapho ukuxhumana phakathi kwamalungu omqhubi kungaqinile futhi ukumelana nokuxhumana kuphezulu kakhulu, ukushisa ngokweqile kwenzeka. Lapho iphuzu lokuthungela le-fiber material lidlula, ukuvutha kwenzeka.
Isakhiwo esingenalutho phakathi kwe-reactor yochungechunge sinquma ukuthi iyindawo ekahle yokuphumula yezinyoni ezihlukahlukene ukuze zakhe izidleke. Uma inani elikhulu le-hay negatsha lezihlahla lingahlanzwa ngesikhathi, lingabangela umlilo noma ukumisa isifunda esifushane ku-reactor.
