ABB UNS4881B V1 3BHE009949R0001 Excitation COB ibhodi
I-ABB UNS4881B V1 3BHE009949R0001 Ibhodi ye-Excitation COB yinxalenye ebalulekileyo yenkqubo yokulawula i-ABB ye-excitation, esetyenziselwa ngokukodwa ukulawula nokulawula iijeneretha ze-synchronous okanye ezinye izixhobo zokuvelisa amandla. I-COB idlala indima ephambili ekulawuleni ukuveliswa kwenkqubo yokuvuselela ukuqinisekisa ukuba i-generator igcina i-voltage ezinzileyo kwaye iqhuba ngokufanelekileyo.
Ibhodi yeCOB iyona nto inoxanduva lokulawula ukukhutshwa kwenkqubo yokuvuselela. Ilawula i-excitation current enika amandla i-rotor ye-generator, iqinisekisa ukuba i-voltage ye-generator ihlala izinzile kwaye ingaphakathi kwimida yokusebenza. Ngokuhlengahlengisa i-excitation, ibhodi ye-COB inceda inkqubo ukuhlawulela utshintsho kumthwalo okanye iimeko zegridi.
Ibhodi ye-COB isebenza njengenxalenye yenkqubo yokulawula i-excitation enkulu, njengaleyo ye-ABB UNITROL okanye ezinye iiplatifomu zokulawula ukuzonwabisa. Idibanisa nomlawuli wokuvuselela, ukufumana iimpawu zokulawula kunye nokuthumela impendulo malunga nokusebenza kwenkqubo.
Isebenzisa imiqondiso yombane kwaye ihlengahlengise i-excitation current, i-voltage exciter, kunye nezinye iiparamitha eziphambili zenkqubo yokuvuselela i-generator ngexesha langempela. Iimpawu eziphumayo zebhodi ye-COB zisetyenziselwa ukulungelelanisa umlawuli we-voltage kunye nomlawuli wangoku wenkqubo yokuvuselela.
Imibuzo edla ngokubuzwa malunga nemveliso yile ilandelayo:
-UNS4881B V1 Yintoni eyenziwa yibhodi ye-COB yokuvuselela?
Ibhodi ye-excitation COB inoxanduva lokulawula imveliso yenkqubo yokuvuselela kwiyunithi yokuvelisa amandla. Ilawula i-excitation current ukuqinisekisa ukuba i-voltage ye-generator ihlala izinzile, ihlawulela ukuhluka komthwalo kunye nokuthintela ukugqithisa okanye iimeko ezingaphantsi kombane.
-Ibhodi yeCOB inceda njani ukulawula amandla ombane wejenereyitha?
Ibhodi ye-COB ilawula i-excitation current enika amandla i-rotor ye-generator, iqinisekisa ukuba umbane we-generator uhlala uzinzile phantsi kweemeko zokusebenza ezahlukeneyo.
-Ibhodi yeCOB inxibelelana njani nayo yonke inkqubo yokuvuselela?
Ibhodi yeCOB inxibelelana nomlawuli we-excitation ophakathi kunye nezinye iimodyuli kwinkqubo. Ifumana izibonakaliso zolawulo kwaye inikezela ngengxelo yexesha langempela kwiiparamitha ezifana ne-excitation current kunye ne-exciter voltage.
