GE IS200DSFCG1AEB Direba Shunt Feedback Card
IS200DSFC 1000/1800 A IGBT Direban Kofar Direba/Shunt Feedback Board (DSFC) yana ƙunshe da da'irorin ganowa na yanzu, da'irar gano kuskure, da da'irorin tuƙi na IGBT guda biyu. Direba da da'irar amsawa sun keɓe ta hanyar lantarki da na gani.
An ƙera jirgin don sababbin dangi na 1000 A da 1800 A pulse wide modulation (PWM) gadoji da direbobin AC. Hukumar DSFC tana mu'amala da sarrafa tuƙi ta hanyar IS200BPIB Drive Bridge Personality Interface Board (BPIB). Gada tushen 1000A ko direba yana buƙatar allunan DSFC guda uku, ɗaya kowane lokaci. Gada tushen 1800A ko direba yana buƙatar allunan DSFC shida, allon "jerin" DSFC guda biyu a kowane lokaci.
An ƙera DSFC (G1) don aikace-aikacen tuƙi/source tare da shigar da AC na 600VLLrms. Allolin DSFC suna hawa kai tsaye zuwa manyan na'urori na IGBT na sama da na ƙasa a cikin kowane ƙafar lokaci don kiyaye fitarwar tuƙi da shunt shigar haɗin yanar gizo a takaice gwargwadon yiwuwa. Ana gyara allon kewayawa ta hanyar haɗi zuwa ƙofar, emitter da mai karɓar IGBT. Domin gano bakin kofa, emitter da ramukan masu tarawa, dole ne a sanya allon kewayawa yadda ya kamata.
Hukumar DSFC ta ƙunshi filogi da masu haɗin huda, masu haɗa rami mai hawa (don haɗawa da IGBTs), da alamun LED a matsayin ɓangare na allon. Babu kayan masarufi masu daidaitawa ko fis a matsayin ɓangare na hukumar. Wutar haɗin kai na DC da wayoyi na hankali na lokacin fitarwa ana haɗa su zuwa tashoshi masu huda. Dukkanin haɗin kai zuwa IGBT ana yin su ta hanyar ramukan hawa a kan hukumar DSFC ta hanyar kayan haɓakawa.
Tushen wutan lantarki
Babban bangaren wutan lantarki na kowane da'irar direba/sa'ido yana da ƙarfi ta hanyar keɓancewa.
An haɗa farkon farkon wannan taswira zuwa ± 17.7 V kololuwa (35.4 V ganiya-zuwa-kolo), 25 kHz murabba'in kalaman. Biyu daga cikin na biyun ukun an gyara rabin igiyar ruwa kuma an tace su don samar da keɓaɓɓen +15V (VCC) da -15V (VEE) (ba a tsara su ba, ± 5% *, matsakaicin matsakaicin 1A ga kowane irin ƙarfin lantarki) wanda babban direban IGBT ke buƙata. kewaye.
Hukumar DSFC tana ƙunshe da masu haɗin kai da masu hudawa, masu haɗa rami mai hawa (don haɗawa da IGBTs), da alamun LED. Babu kayan masarufi masu daidaitawa ko fis a kan allo. Wutar haɗin kai na DC da na'urorin ma'aunin wutar lantarki na lokacin fitarwa suna haɗuwa da tashoshi masu huda. Dukkanin haɗin kai zuwa IGBT ana yin su ta hanyar haɓaka kayan aiki ta hanyar hawan ramuka akan allon DSFC.
Sakandare na uku an daidaita shi da cikakken igiyar ruwa kuma an tace shi don samar da wutar lantarki keɓewar ± 12 V da ake buƙata don shunt halin yanzu mai sarrafa ƙarfin lantarki mai sarrafa oscillator da da'irorin gano kuskure (wanda ba a tsara shi ba, ± 10%, matsakaicin matsakaicin 100 mA ga kowane). Da'irar shunt kuma tana buƙatar wadatar dabaru na 5 V (± 10%, matsakaicin matsakaicin 100 mA), wanda aka samar ta hanyar mai sarrafa layin 5 V da aka haɗa da wadatar +12 V. Ana sarrafa wadatar 5V kawai.

-Mene ne GE IS200DSFCG1AEB Drive Shunt Feedback Card?
-IS200DSFCG1AEB shine katin amsawa na shunt da aka yi amfani da shi a cikin tsarin sarrafa turbine na Speedtronic. An ƙera shi don sarrafa amsawa daga exciter (ko janareta), sarrafa ikon zuwa injin injin turbine. Wannan ra'ayi yana da mahimmanci don kiyaye saurin gudu da aiki na turbine ta hanyar daidaitawa da fitarwa na exciter dangane da ainihin aikin rotor.
Menene manyan ayyukan IS200DSFCG1AEB?
Yana aiwatar da sigina daga injin turbine exciter ko janareta don tabbatar da cewa an samar da ingantaccen martani ga tsarin sarrafawa. Katin yana taimakawa sarrafa ka'idojin wutar lantarki ta hanyar ba da amsa daga da'irar shunt exciter don kiyaye fitar da wutar lantarki na injin turbine a cikin kewayo mai aminci. IS200DSFCG1AEB yana daidaita sigina don tabbatar da cewa sun dace don amfani da tsarin sarrafa injin turbin. Har ila yau, ita ce ke da alhakin sa ido kan abubuwan motsa jiki da janareta don kurakurai ko ƙimar da ba ta cikin kewayon, samar da kariya ga tsarin lantarki na injin turbine. Katin yana sadarwa tare da sauran tsarin kula da turbine, yana tabbatar da daidaituwa tsakanin saurin turbine, kaya, da fitarwa na lantarki.
-Mene ne manyan abubuwan IS200DSFCG1AEB?
Microcontroller/processor yana aiwatar da siginar martani.
Da'irar sanyaya sigina tana tacewa kuma tana daidaita siginonin amsa mai shigowa zuwa mai sarrafa injin turbine.
Ana amfani da masu haɗawa da tashoshi don yin hulɗa tare da exciter da sauran abubuwan da ke cikin tsarin lantarki na turbine.
Ana amfani da fitilun mai nuna alama don saka idanu, rahoton kuskure, da bincike.
Ana amfani da tashoshin shigarwa / fitarwa (I / O) don sadarwa tare da wasu nau'ikan sarrafawa a cikin tsarin sarrafa injin turbine.
