ABB UNS4881B V1 3BHE009949R0001 Excitation COB board
I-ABB UNS4881B V1 3BHE009949R0001 Ibhodi le-COB le-Excitation liyingxenye ebalulekile yesistimu yokulawula ukuvusa amadlingozi ye-ABB, esetshenziselwa ngokukhethekile ukulawula nokulawula amajeneretha ahambisanayo noma ezinye izisetshenziswa zokuphehla amandla. I-COB idlala indima ebalulekile ekulawuleni ukuphuma kwesistimu ye-excitation ukuze kuqinisekiswe ukuthi i-generator igcina i-voltage ezinzile futhi isebenza kahle.
Ibhodi ye-COB inomthwalo wemfanelo ngokuyinhloko wokulawula ukuphuma kwesistimu ye-excitation. Ilawula amandla e-excitation current enika amandla i-rotor generator, iqinisekisa ukuthi i-voltage ye-generator ihlala izinzile futhi ingaphakathi kwemikhawulo yokusebenza. Ngokulungisa isasasa, ibhodi le-COB lisiza uhlelo ukunxephezela izinguquko kumthwalo noma izimo zegridi.
Ibhodi le-COB lisebenza njengengxenye yesistimu yokulawula injabulo enkulu, njengalezo eziku-ABB UNITROL noma ezinye izinkundla zokulawula injabulo. Isebenzisana nesilawuli esivusa amadlingozi, ithola amasignali okulawula futhi ibuyisela impendulo mayelana nokusebenza kwesistimu.
Icubungula amasignali kagesi futhi ilungise i-excitation current, i-exciter voltage, namanye amapharamitha angukhiye wesistimu ye-generator excitation ngesikhathi sangempela. Izimpawu eziphumayo zebhodi le-COB zivame ukusetshenziselwa ukulungisa isilawuli samandla kagesi kanye nesilawuli samanje sesistimu ye-excitation.
Imibuzo evame ukubuzwa ngomkhiqizo imi kanje:
-UNS4881B V1 Lenzani ibhodi ye-COB ethokozisayo?
Ibhodi le-COB elivusa amadlingozi linomthwalo wemfanelo wokulawula ukukhishwa kwesistimu ye-excitation kuyunithi yokukhiqiza amandla. Ilawula amandla e-excitation current ukuze kuqinisekiswe ukuthi i-voltage ephehla ugesi ihlala izinzile, inxephezela ukuhlukahluka komthwalo futhi ivimbela ukugcwala ngokweqile noma izimo zokungabi namandla.
-Ibhodi le-COB lisiza kanjani ukulawula i-voltage ye-generator?
Ibhodi le-COB lilawula amandla e-excitation current enika amandla i-rotor generator, iqinisekisa ukuthi i-voltage ye-generator ihlala izinzile ngaphansi kwezimo zokusebenza ezihlukene.
-Ibhodi le-COB lixhumana kanjani nalo lonke uhlelo lokuvusa amadlingozi?
Ibhodi le-COB lixhumana nesilawuli sokuvusa amadlingozi namanye amamojula ohlelweni. Ithola amasignali okulawula futhi inikeza impendulo yesikhathi sangempela kumapharamitha afana ne-excitation current kanye ne-exciter voltage.
