Raws li cov cuab yeej tseem ceeb hauv lub zog hluav taws xob, lub tshuab hluav taws xob hloov pauv ua lub luag haujlwm tseem ceeb hauv kev faib hluav taws xob hluav taws xob los ntawm qhov system high-voltage mus rau cov neeg siv hluav taws xob tsawg kawg. Nws ua kom muaj kev nyab xeeb, ruaj khov thiab muaj txiaj ntsig sib kis ntawm hluav taws xob hluav taws xob los ntawm cov txheej txheem nyuaj thiab cov cuab yeej tswj hwm. Niaj hnub no peb yuav saib cov ncauj lus kom ntxaws txog kev ua haujlwm ntawm cov keyboards.
I. Kev faib tawm txoj cai
Lub hauv paus ntsiab lus ntawm lub switchboard yog hloov hluav taws xob hluav taws xob los ntawm high-voltage system mus rau qhov qis-voltage system thiab faib cov hluav taws xob hluav taws xob rau ntau yam khoom siv hluav taws xob. Thaum lub high-voltage hluav taws xob hluav taws xob nkag mus rau lub switchboard, lub voltage yog thawj zaug txo mus rau ib tug haum theem los ntawm lub transformer kom cov khoom tom ntej yuav ua hauj lwm yam xyuam xim thiab stably. Lub switchboard siv sab hauv busbars, keyboards, cables thiab lwm yam khoom, thiab lub busbar ua hauj lwm raws li ib tug kis tau tus mob channel rau hluav taws xob lub zog xa hluav taws xob rau txhua qhov tso zis hloov. Tom qab ntawd, los ntawm kev ua haujlwm ntawm qhov hloov pauv, lub zog hluav taws xob tau muab faib rau cov ceg sib txawv, thiab lub sijhawm tam sim no loj thiab lub zog siv hluav taws xob ntawm txhua ceg yog tswj tau raws li qhov xav tau. Qhov kev faib tawm no ua kom muaj kev siv hluav taws xob zoo thiab kev ua haujlwm ntawm cov khoom siv.
II. Txoj cai kev nyab xeeb
Nyob rau hauv kev tsim ntawm lub switchboard, kev nyab xeeb yog ib qho tseem ceeb hauv paus ntsiab lus. Nws siv cov cuab yeej tiv thaiv sib txawv, xws li fuses, cua hloov pauv thiab cov contactors, txhawm rau txheeb xyuas thiab cais cov hluav taws xob tsis raug. Thaum overload, luv luv Circuit Court los yog lwm yam kev txawv txav tshwm sim nyob rau hauv lub Circuit Court, cov khoom tiv thaiv no yuav cia li disconnect lub Circuit Court los tiv thaiv cov khoom puas thiab hluav taws kub. Lub switchboard kuj tau txais cov qauv kaw thiab kev tiv thaiv los tiv thaiv cov neeg ua haujlwm los ntawm kev tiv tauj ncaj qha rau qhov chaw nyob, yog li tiv thaiv kev nyab xeeb ntawm cov neeg ua haujlwm. Tsis tas li ntawd, lub switchboard kuj tseem muaj kev tiv thaiv hauv av kom ntseeg tau tias muaj av zoo ntawm cov hlau ncej thiab cov khoom siv casing, ntxiv kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov khoom siv.
III. Tswj txoj cai
Lub switchboard muaj lub luag haujlwm ntawm kev tswj lub Circuit Court. Los ntawm cov khoom xws li cov keyboards thiab Circuit Court breakers, lub Circuit Court tuaj yeem hloov mus rau, tawm, kev sib txuas, thiab lwm yam. Cov kev tswj xyuas Circuit Court yog ib qho tseem ceeb ntawm lub switchboard. Nws faib, tswj thiab tswj lub zog hluav taws xob raws li cov lus qhia lossis cov cim. Los ntawm kev tswj xyuas Circuit Court, lub switchboard tuaj yeem ua tau raws li qhov xav tau ntawm cov khoom siv hluav taws xob sib txawv rau lub zog hluav taws xob, xws li pib, nres, kev tswj ceev, thiab lwm yam. Qhov kev tswj xyuas no ua rau lub zog hluav taws xob hloov pauv hloov pauv raws li kev hloov pauv kom ruaj khov. ntawm hluav taws xob. Tsis tas li ntawd, lub switchboard tseem tuaj yeem paub cov chaw taws teeb tswj thiab kev tswj tsis siv neeg los txhim kho kev khiav hauj lwm zoo thiab kev ntseeg siab ntawm lub zog hluav taws xob.
IV. Kev tiv thaiv txoj cai
Lub rooj sib faib khoom kuj muaj kev ua haujlwm ntawm kev tiv thaiv circuits thiab khoom siv. Nws tuaj yeem saib xyuas qhov tsis xws li tam sim no, qhov hluav taws xob, qhov kub thiab txias, thiab ua rau cov khoom siv tiv thaiv sib xws raws li qhov ntsuas kev tiv thaiv. Thaum kuaj pom qhov txawv txav tsis zoo, cov cuab yeej tiv thaiv yuav ua sai sai rau kev sib txuas ntawm lub faulty Circuit Court tiv thaiv cov khoom puas lossis hluav taws kub. Piv txwv li, thaum tam sim no loj heev, lub overcurrent tiv thaiv ntaus ntawv yuav txiav tawm lub Circuit Court; Thaum qhov kub thiab txias dhau lawm, cov cuab yeej tiv thaiv kub yuav ua rau lub tswb nrov lossis txiav tawm lub hwj chim. Cov txheej txheem tiv thaiv no pab txhawm rau txuas lub neej kev pabcuam ntawm cov cuab yeej siv thiab txo lub sijhawm hluav taws xob hluav taws xob los ntawm kev ua txhaum.
V. Kev sib xyaw, kev ua haujlwm thiab hom kev faib khoom pawg thawj coj saib
Lub rooj tsav xwm faib khoom feem ntau yog tsim los ntawm lub txee, qhov hloov pauv (circuit breaker), cov cuab yeej tiv thaiv, cov cuab yeej saib xyuas, lub ntsuas hluav taws xob thiab lwm yam khoom nruab nrab.
Txee:Raws li lub plhaub sab nraud ntawm lub rooj sib faib khoom, nws muab kev tiv thaiv thiab kev txhawb nqa.
Hloov (circuit breaker):Lub luag haujlwm rau kev tswj lub hauv thiab tawm ntawm Circuit Court kom ua tiav qhov kev faib tawm thiab kev tiv thaiv hluav taws xob hluav taws xob.
Cov cuab yeej tiv thaiv:xws li fuses, cua hloov pauv, thiab lwm yam, siv los kuaj xyuas thiab cais cov faulty circuits.
Cov cuab yeej saib xyuas:xws li ammeters, voltmeters, thiab lwm yam, siv los saib xyuas kev siv hluav taws xob hluav taws xob hauv Circuit Court hauv lub sijhawm.
Zog ntsuas:siv los ntsuas thiab sau cov kev siv hluav taws xob, muab lub hauv paus rau kev them nqi thiab kev tswj hwm ntawm cov tuam txhab fais fab.
Nyob ntawm tus qauv thiab lub hom phiaj, lub switchboard tuaj yeem muab faib uatsau vaj huam sib luag switchgear, tiv thaiv (cuam tshuam) switchgear thiabtub rau khoom switchgear. Cov kev sib txawv ntawm cov keyboards no haum rau ntau lub sijhawm thiab kev xav tau, xws li kev lag luam thiab kev lag luam mining, cov tsev siab siab thiab cov neeg siv hluav taws xob.
VI. Kev tu thiab kev daws teeb meem ntawm switchboards
Txhawm rau kom ntseeg tau tias qhov kev ua haujlwm ib txwm muaj ntawm lub switchboard, nws yog ib qho tsim nyog yuav tsum tau tswj thiab tshuaj xyuas nws tsis tu ncua. Qhov no suav nrog kev tu lub ntsej muag ntawm cov khoom siv, tshuaj xyuas kev sib cuag ntawm cov keyboards thiab fuses, zawm xoob xaim, thiab lwm yam. Nyob rau tib lub sijhawm, nws tseem yuav tsum tau ua cov kev ntsuam xyuas kev tiv thaiv ntawm lub switchboard tsis tu ncua kom ntseeg tau tias nws ntau yam kev ua tau zoo raws li qhov yuav tsum tau ua. . Thaum lub switchboard ua tsis tau, nws yuav tsum tau ceev nrooj nyob thiab daws teeb meem. Qhov no feem ntau xav kom cov kws tshaj lij hluav taws xob ua haujlwm, kuaj xyuas qhov ua txhaum ntawm kev siv ntau yam cuab yeej tshawb nrhiav, thiab siv cov kev ntsuas tsim nyog los kho nws.
Nyob rau hauv cov ntsiab lus, lub switchboard paub txog kev faib thiab kev tswj ntawm hluav taws xob hluav taws xob los ntawm cov hauv paus ntsiab lus ntawm kev faib hluav taws xob, kev nyab xeeb, kev tswj thiab kev tiv thaiv. Nws yog ib qho ntawm cov khoom siv tseem ceeb hauv lub zog hluav taws xob thiab tseem ceeb heev los xyuas kom muaj kev nyab xeeb thiab ruaj khov ntawm lub zog hluav taws xob. Los ntawm kev siv thiab tswj cov cuab yeej tseem ceeb no, kev sib kis tau zoo thiab kev siv hluav taws xob tuaj yeem ua kom ntseeg tau, muab kev lees paub rau kev nyab xeeb thiab ruaj khov ntawm lub zog hluav taws xob.
