ABB UNS4881B V1 3BHE009949R0001 Excitation COB board
ABB UNS4881B V1 3BHE009949R0001 Excitation COB board yog ib feem tseem ceeb ntawm ABB excitation tswj system, tshwj xeeb yog siv los tswj thiab tswj cov tshuab hluav taws xob synchronous lossis lwm yam khoom siv hluav taws xob. COB plays lub luag haujlwm tseem ceeb hauv kev tswj cov khoom tso tawm ntawm qhov kev tawm dag zog kom ntseeg tau tias lub tshuab hluav taws xob tswj tau qhov hluav taws xob ruaj khov thiab ua haujlwm tau zoo.
COB pawg thawj coj saib yog lub luag haujlwm tseem ceeb rau kev tswj cov khoom tsim tawm ntawm lub zog excitation. Nws tswj cov excitation tam sim no uas powers lub generator rotor, kom ntseeg tau tias lub tshuab hluav taws xob voltage tseem nyob ruaj khov thiab nyob rau hauv kev txwv tsis pub khiav hauj lwm. Los ntawm kev kho qhov excitation, COB board pab lub kaw lus them nyiaj rau cov kev hloov pauv hauv kev thauj khoom lossis kab sib chaws.
Lub COB pawg thawj coj ua haujlwm ua ib feem ntawm kev tswj hwm kev ua kom muaj zog loj dua, xws li cov hauv ABB UNITROL lossis lwm qhov kev tswj hwm kev zoo siab. Nws cuam tshuam nrog tus maub los excitation, tau txais kev tswj cov cim thiab xa rov qab tawm tswv yim txog kev ua haujlwm ntawm lub cev.
Nws ua cov cim hluav taws xob thiab kho qhov excitation tam sim no, exciter voltage, thiab lwm yam tsis tseem ceeb ntawm lub tshuab hluav taws xob excitation system nyob rau lub sijhawm. Cov zis tawm ntawm COB lub rooj tsavxwm feem ntau yog siv los kho qhov voltage regulator thiab tam sim no regulator ntawm lub excitation system.
Cov lus nug nquag nug txog cov khoom yog raws li hauv qab no:
-UNS4881B V1 Dab tsi yog qhov excitation COB board ua?
Lub excitation COB board yog lub luag hauj lwm rau kev tswj cov zis ntawm lub excitation system nyob rau hauv lub hwj chim tsim unit. Nws tswj cov excitation tam sim no los xyuas kom meej tias lub tshuab hluav taws xob hluav taws xob nyob ruaj khov, them nyiaj rau kev hloov pauv thiab tiv thaiv overvoltage lossis undervoltage tej yam kev mob.
-COB board pab tswj lub tshuab hluav taws xob li cas?
Lub COB board tswj cov excitation tam sim no uas powers lub generator rotor, kom ntseeg tau tias lub tshuab hluav taws xob voltage tseem nyob ruaj khov nyob rau hauv ntau yam kev khiav hauj lwm.
-COB pawg thawj coj sib txuas lus li cas nrog rau lwm qhov kev ua kom zoo siab?
COB board sib txuas lus nrog lub hauv paus excitation maub los thiab lwm yam modules nyob rau hauv lub system. Nws tau txais kev tswj cov teeb liab thiab muab cov lus tawm tswv yim ntawm lub sijhawm ntawm qhov tsis xws li excitation tam sim no thiab exciter voltage.
