Detailed data
ABB UNS4881B V1 3BHE009949R0001 Excitation COB board
ABB UNS4881B V1 3BHE009949R0001 Excitation COB bhodhi chikamu chakakosha cheABB excitation control system, iyo inonyanya kushandiswa kudzora nekudzora synchronous jenareta kana mamwe magetsi ekugadzira magetsi. COB inobata basa rakakosha mukugadzirisa kuburitsa kweiyo excitation system kuti ive nechokwadi chekuti jenareta inochengetedza voltage yakagadzikana uye inomhanya nemazvo.
Iyo COB board inonyanya kuita basa rekudzora kubuda kweiyo excitation system. Iyo inodzora iyo yekunakidzwa ikozvino inopa simba jenareta rotor, kuve nechokwadi chekuti jenareta voltage inoramba yakagadzikana uye mukati memiganho yekushandisa. Nekugadzirisa mafambiro, iyo COB board inobatsira iyo system kubhadhara shanduko yemutoro kana grid mamiriro.
Iyo COB bhodhi inoshanda sechikamu cheyakakura yekuwedzeredza yekudzora sisitimu, senge iyo iri muABB UNTROL kana mamwe mapuratifomu ekusimudzira manejimendi. Iyo inopindirana neyekunakidzwa controller, inogamuchira masaini ekudzora uye kutumira kumashure mhinduro nezve system performance.
Iyo inobata masaini emagetsi uye inogadzirisa iyo exciter ikozvino, exciter voltage, uye mamwe akakosha ma paramita ejenareta excitation system munguva chaiyo. Iwo anobuda masaini eCOB board anowanzo shandiswa kugadzirisa voltage regulator uye yazvino regulator yeiyo excitation system.
Mibvunzo inowanzo bvunzwa nezvechigadzirwa ndeiyi:
-UNS4881B V1 Ko iyo excitation COB board inoita sei?
Iyo excitation COB board ine basa rekudzora kuburitswa kweiyo excitation system muchikamu chekugadzira magetsi. Iyo inogadzirisa iyo yekunakidzwa ikozvino kuti ive nechokwadi chekuti jenareta voltage inoramba yakagadzikana, inotsiva misiyano yemutoro uye inodzivirira overvoltage kana undervoltage mamiriro.
-Ko bhodhi reCOB rinobatsira sei kugadzirisa magetsi ejenareta?
Bhodhi reCOB rinogadzirisa ikozvino kunakidza iyo inopa simba jenareta rotor, kuve nechokwadi chokuti jenareta voltage inoramba yakagadzikana pasi pemamiriro ekushanda akasiyana.
-Ko bhodhi reCOB rinotaurirana sei nedzimwe nzira yekukurudzira?
Iyo COB board inotaurirana neyepakati excitation controller uye mamwe ma module muhurongwa. Iyo inogashira masaini ekudzora uye inopa chaiyo-nguva mhinduro pamaparamita akadai seyekuwedzeredza ikozvino uye exciter voltage.
