Nyob rau hauv lub zog system,nplhaib lub ntsiab unitthiab hloov txee yog ob qho khoom siv tseem ceeb, txhua tus xav tias muaj lub luag haujlwm sib txawv thiab ua lub luag haujlwm tsis tuaj yeem hloov pauv. Txawm hais tias lawv txhua tus muaj nyob rau hauv qeb ntawm cov khoom siv hluav taws xob, muaj qhov sib txawv tseem ceeb hauv cov qauv, kev ua haujlwm, daim ntawv thov scenarios, thiab lwm yam.
Txhais thiab cov qauv tsim
Nplhaib lub ntsiab unit
RMU, tseem hu ua nruab nrab-voltage nplhaib lub ntsiab chav tsev, yog ib hom tshwj xeeb ntawm kev hloov khoom siv, feem ntau yog siv hauv lub nplhaib network fais fab. Nws cov khoom tseem ceeb suav nrog cov hloov pauv thiab cov fuses, uas tau teeb tsa hauv cov hlau lossis cov khoom tsis yog hlau. Cov qauv ntawm lub nplhaib tseem ceeb yog qhov yooj yim, me me, thiab yooj yim rau nruab thiab tswj. Nws feem ntau siv cov hloov pauv thiab cov fuses ua cov khoom tseem ceeb. Lub load hloov muaj peb txoj haujlwm ua haujlwm: on, off and grounding. Cov kev teeb tsa ntawm cov haujlwm no ua rau lub nplhaib tseem ceeb ntawm chav tsev hloov tau yooj yim thiab nyab xeeb thaum ua haujlwm. poj niam deev. Fuses, ntawm qhov tod tes, yog siv los tiv thaiv circuits los ntawm kev ua txhaum xws li overloads thiab luv circuits.
Switchgear
Switchgear yog cov khoom siv hluav taws xob ntau dua siv rau kev faib hluav taws xob, tswj thiab kev tiv thaiv hauv cov tshuab hluav taws xob. Nws suav nrog ntau yam khoom siv hloov pauv (xws li cov hluav taws xob hluav taws xob, cov hluav taws xob sib cais, thiab lwm yam), ntsuas ntsuas, cov cuab yeej tiv thaiv thiab cov tshuab tswj tsis siv neeg. Tus qauv ntawmlub txee hloovNws yog ib qho nyuaj thiab muaj ntau yam kev ua haujlwm, xws li chav tsev busbar, chav tsev Circuit Court breaker, chav tswj theem nrab, thiab lwm yam. Cov chav ua haujlwm no ua haujlwm ua ke kom ruaj khov ntawm lub zog hluav taws xob.
Nta
Nplhaib lub ntsiab unit
Lub luag haujlwm tseem ceeb ntawm lubnplhaib lub ntsiab unityog los faib hluav taws xob hluav taws xob thiab tswj lub hauv thiab tawm ntawm lub voj voog. Nws feem ntau yog siv rau hauv kev hloov pauv thiab kev tsim kho ntawm cov phiaj xwm hluav taws xob hauv nroog, nrog rau cov phiaj xwm automation ntawm cov phiaj xwm hluav taws xob hauv nroog thiab nyob deb nroog. Lub load hloov ntawm lub nplhaib lub ntsiab chav tsev muaj peb txoj haujlwm ua haujlwm: on, off and grounding, uas yog yooj yim rau kev khiav hauj lwm thiab txij nkawm. Nyob rau tib lub sijhawm, raws li kev tiv thaiv kev tiv thaiv, fuses tuaj yeem txiav tawm sai sai thaum muaj kev sib tsoo lossis luv luv los tiv thaiv kev nyab xeeb ntawm cov khoom siv thiab cov neeg ua haujlwm.
Switchgear
Lub luag haujlwm ntawm lub txee hloov pauv tau ua tiav ntau dua. Nws tuaj yeem tsis tsuas yog paub txog kev hloov pauv thiab kev tswj hwm ntawm circuits, tab sis kuj ua haujlwm xws li kev tiv thaiv, ntsuas thiab saib xyuas cov tshuab hluav taws xob. Lub Circuit Court breaker nyob rau hauv lub switchgear yog cov tseem ceeb tivthaiv uas muaj peev xwm ua, tawg thiab nqa ib txwm thiab txhaum tam sim no. Thaum muaj teeb meem hauv Circuit Court, lub Circuit Court breaker tuaj yeem txiav tawm sai sai kom tsis txhob muaj qhov txhaum ntawm kev nthuav dav. Tsis tas li ntawd, lub txee hloov pauv tseem muaj ntau yam ntsuas ntsuas thiab cov cuab yeej tiv thaiv, uas yog siv los saib xyuas kev ua haujlwm ntawm lub zog hluav taws xob hauv lub sijhawm tiag tiag thiab xyuas kom muaj kev nyab xeeb thiab ruaj khov ntawm kev ua haujlwm.
Daim ntawv thov scenarios
Nplhaib lub ntsiab unit
Nplhaib network txee yog siv nyob rau hauv lub nplhaib network fais fab mov systems raws li lub hwj chim tiv tauj los yog kab segment tswj cov khoom. Nws yog qhov tsim nyog rau cov tshuab xa hluav taws xob uas yuav tsum tau muaj kev ntseeg siab thiab hloov tau yooj yim, xws li hauv nroog cov phiaj xwm hluav taws xob, chaw ua si, thiab thaj chaw lag luam. Kev taw qhia ntawm lub nplhaib tseem ceeb tuaj yeem ua kom yooj yim rau cov qauv ntawm lub zog faib hluav taws xob thiab txhim kho kev ntseeg tau thiab hloov tau yooj yim ntawm cov khoom siv hluav taws xob. Nyob rau tib lub sijhawm, vim nws cov qauv yooj yim, me me, yooj yim installation thiab txij nkawm, lub nplhaib lub ntsiab chav tsev yog nce siv hauv cov tshuab hluav taws xob.
Switchgear
Switchgear yog dav siv nyob rau hauv ntau yam ntawm lub hwj chim systems, xws li fais fab nroj tsuag, substations, tis chaw nres tsheb, thiab lwm yam. Txawm hais tias nws yog ib tug high-voltage fais fab system los yog ib tug low-voltage fais fab system, switchgear plays lub luag hauj lwm tseem ceeb. Nws tuaj yeem paub txog kev hloov pauv thiab tswj cov circuits, tiv thaiv kev nyab xeeb ntawm cov khoom siv thiab cov neeg ua haujlwm, thiab tseem tuaj yeem saib xyuas kev ua haujlwm ntawm lub zog hluav taws xob hauv lub sijhawm tiag tiag los ntawm kev ntsuas ntsuas thiab cov cuab yeej tiv thaiv. Qhov sib txawv thiab yooj yim ntawm switchgear cia nws hloov mus rau qhov sib txawv daim ntawv thov scenarios thiab xav tau kev pab.
