ABB UNS4881B V1 3BHE009949R0001 Excitation COB board
ABB UNS4881B V1 3BHE009949R0001 Boto ea Phatlalatso ea COB ke karolo ea bohlokoa ea sistimi ea taolo ea phepelo ea ABB, e sebelisoang ka ho khetheha ho laola le ho laola lijenereithara tsa synchronous kapa lisebelisoa tse ling tsa ho fehla matla. COB e bapala karolo ea bohlokoa ho laola tlhahiso ea mokhoa oa ho hlasimolla ho netefatsa hore jenereithara e boloka motlakase o tsitsitseng mme e sebetsa hantle.
Boto ea COB ke eona e ikarabellang haholo bakeng sa ho laola tlhahiso ea sistimi ea excitation. E laola motlakase oa motlakase o matlafatsang rotor ea jenereithara, ho netefatsa hore motlakase oa jenereithara o lula o tsitsitse le ka har'a meeli ea ts'ebetso. Ka ho fetola thabo, boto ea COB e thusa tsamaiso ho lefella liphetoho tsa mojaro kapa maemo a marang-rang.
Boto ea COB e sebetsa e le karolo ea sistimi e kholoanyane ea taolo ea litlatsetso, joalo ka tse ho ABB UNITROL kapa li-platform tse ling tsa taolo ea menyaka. E hokahana le molaoli oa ho hlasimolla, ho amohela matšoao a taolo le ho khutlisetsa maikutlo mabapi le ts'ebetso ea sistimi.
E sebetsana le mats'oao a motlakase 'me e lokisa maqhubu a hlasimollang, motlakase oa exciter, le likarolo tse ling tsa bohlokoa tsa sistimi ea ho hlasimolla jenereithara ka nako ea nnete. Lipontšo tsa tlhahiso ea boto ea COB hangata li sebelisoa ho lokisa motlakase oa motlakase le molaoli oa hajoale oa sistimi e hlasimollang.
Lipotso tse atisang ho botsoa ka sehlahisoa ke tse latelang:
-UNS4881B V1 Boto ea COB e hlasimollang e etsa eng?
Boto ea COB e hlasimollang e na le boikarabello ba ho laola tlhahiso ea sistimi ea ho hlasimolla yuniti ea tlhahiso ea matla. E laola motlakase oa motlakase ho netefatsa hore motlakase oa jenereithara o lula o tsitsitse, o lefella mefuta e fapaneng ea mojaro le ho thibela maemo a overvoltage kapa undervoltage.
-Boto ea COB e thusa joang ho laola motlakase oa jenereithara?
Boto ea COB e laola maqhubu a hlasimollang a matlafatsang rotor ea jenereithara, ho netefatsa hore motlakase oa jenereithara o lula o tsitsitse tlas'a maemo a fapaneng a ts'ebetso.
-Boto ea COB e buisana joang le tsamaiso eohle ea ho hlasimolla?
Boto ea COB e buisana le molaoli oa bohareng oa excitation le li-module tse ling tsamaisong. E amohela matšoao a taolo 'me e fana ka maikutlo a nako ea nnete ho li-parameter tse kang excitation current le exciter voltage.
