Kev piav qhia

Lub SPM-A Synchronizer cuam tshuam qhov ceev ntawm lub tshuab hluav taws xob off-line teeb kom qhov zaus thiab theem sib xws ntawm lwm lub tshuab hluav taws xob lossis lub tsheb thauj mus los. Tom qab ntawd nws cia li teeb tsa qhov kev sib cuag kaw kom kaw lub Circuit Court breaker ntawm ob lub sijhawm thiab theem sib phim hauv qhov txwv rau lub sijhawm sib tw. SPM-A yog ib theem-locked-loop synchronizer thiab sib zog ua kom muaj kev sib tw zoo meej ntawm zaus thiab theem.

SPM-A Synchronizer nrog qhov sib txuam voltage ua rau muaj kev nce ntxiv thiab qis dua (relay tiv tauj kaw) rau lub tshuab hluav taws xob qhov ntsuas hluav taws xob. Voltages yuav tsum sib phim nyob rau hauv lub SPM-A lub kam rau ua ua ntej breaker kaw tshwm sim. Rau ib chav tsev synchronization, kev teeb tsa ntawm ib qho synchronizer ntawm txhua lub tshuab hluav taws xob tso cai rau txhua chav nyob ib leeg mus rau lub tsheb npav. Rau multipleunit synchronization, ib lub synchronizer tuaj yeem synchronize txog li xya lub tshuab hluav taws xob sib txuas ib txhij mus rau lwm lub tsheb npav. Ob lub tshuab synchronizers muaj peb qhov kev xaiv tso zis: siab impedance, qis impedance, thiab EPG.

Xaiv lub siab impedance tso zis rau ib leeg-unit synchronization thaum lub cav yog tswj los ntawm Woodward 2301 tswj. Xaiv cov zis impedance qis rau ib qho kev sib koom ua ke thaum lub cav raug tswj los ntawm Woodward 2301A, 2500, lossis Electrically Powered Governor (EPG) tswj los ntawm Generator Load Sensor. Siv cov zis EPG thaum siv Woodward EPG tswj yam tsis muaj kev nkag siab. Ob chav units muaj cov nram qab no nta:

 120 lossis 208/240 Vac input

 10 degree theem qhov rais

 1/8, 1/4, 1/2, los yog 1 thib ob nyob lub sij hawm (sab hauv hloov xaiv, Hoobkas teem rau 1/2 thib ob) SPM-A Synchronizer nrog voltage txuam muaj 1% voltage match raws li tus qauv. Saib daim ntawv qhia tus lej rau lwm cov kev xaiv.

Txoj Kev Ua Haujlwm

Tshooj lus no piav qhia txog txoj kev xav dav dav ntawm kev ua haujlwm ntawm ob lub qauv ntawm SPM-A Synchronizer. Daim duab 1-1 qhia tau hais tias SPM-A Synchronizer nrog voltage txuam. Daim duab 1-2 qhia tau hais tias ib txwm synchronizer system thaiv daim duab. Daim duab 1-3 qhia txog kev ua haujlwm thaiv daim duab ntawm lub synchronizer.

Synchronizer inputs

SPM-A Synchronizer xyuas lub kaum sab xis thiab zaus ntawm lub tsheb npav thiab lub tshuab hluav taws xob off-line uas yuav tsum tau ua tib yam. Qhov voltage inputs los ntawm lub tsheb npav thiab lub tshuab hluav taws xob yog thawj zaug siv rau cais cov teeb liab cua txias circuits. Txhua lub teeb liab txias yog lub lim uas hloov cov duab ntawm qhov hluav taws xob tawm tswv yim kom lawv tuaj yeem ntsuas qhov tseeb. Ib theem offset potentiometer nyob rau hauv lub teeb liab cua txias Circuit Court yog kho kom them nyiaj rau theem yuam kev. (Qhov kev hloov kho no yog lub Hoobkas teeb tsa nrog cov tsheb npav zoo ib yam thiab cov khoom siv hluav taws xob sib xyaw. Nws yuav tsum tau hloov kho tsuas yog qhov twg ib theem offset tau tshwm sim los ntawm cov kab transformers ntawm kev teeb tsa.) Cov teeb liab cua txias kuj ua kom lub tsheb npav thiab lub tshuab hluav taws xob muaj zog thiab siv rau theem. ntes.

Kev Ua Haujlwm Hom Ib tus neeg siv kev teeb tsa hom hloov (ib leeg-ncej, plaub-txoj haujlwm) tswj tus tsav tsheb relay.

Qhov hloov pauv yuav tsum tau xa mus rau synchronizer hu 10 txog 13 (saib cov kab kos duab cog). Plaub txoj haujlwm yog OFF, RUN, CHECK, thiab PERMISSIVE.
