Cov Khoom Siv Tshawb Xyuas Arc FaultXyuas Kom Muaj Kev Nyab Xeeb thiab Tiv Thaiv Hluav Taws Xob
Hauv lub ntiaj teb niaj hnub no, qhov uas thev naus laus zis siab heev tau dhau los ua ib feem tseem ceeb ntawm peb lub neej, kev nyab xeeb ntawm hluav taws xob tau dhau los ua qhov tseem ceeb. Hluav taws xob yog qhov kev hem thawj tas li uas tuaj yeem ua rau puas tsuaj, raug mob, lossis txawm tias tuag. Txawm li cas los xij, thaum thev naus laus zis nce qib, tam sim no peb muaj ib lub cuab yeej hu ua lub cuab yeej nrhiav qhov txhaum arc los tawm tsam qhov kev phom sij no.
Cov khoom siv nrhiav qhov txhaum arc (feem ntau hu uaCov AFDD) yog ib feem tseem ceeb ntawm cov tshuab hluav taws xob niaj hnub no. Nws yog tsim los tiv thaiv cov teeb meem arc, uas tshwm sim thaum tam sim no ntws los ntawm txoj kev tsis xav tau. Cov teeb meem no tuaj yeem tsim cov cua sov, hluav taws xob, thiab nplaim taws uas tuaj yeem ua rau muaj hluav taws xob.
Lub luag haujlwm tseem ceeb ntawm AFDD yog saib xyuas cov hluav taws xob ntws hauv lub voj voog thiab nrhiav pom txhua qhov teeb meem arcing uas yuav tshwm sim. Tsis zoo li cov circuit breakers txheem uas tsuas yog muab kev tiv thaiv overcurrent, AFDDs tuaj yeem txheeb xyuas cov yam ntxwv tshwj xeeb ntawm arc faults, xws li voltage nce sai thiab cov waveforms tsis xwm yeem. Thaum pom qhov teeb meem arc, AFDD yuav ua haujlwm tam sim ntawd los txiav hluav taws xob thiab tiv thaiv hluav taws kom tsis txhob kis mus.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov khoom siv nrhiav arc fault yog nws lub peev xwm los paub qhov txawv ntawm cov arcs tsis muaj teeb meem, xws li cov uas tsim los ntawm cov khoom siv hauv tsev, thiab cov arcs txaus ntshai uas tuaj yeem ua rau muaj hluav taws. Qhov feature no pab txo qhov kev pheej hmoo ntawm kev ceeb toom cuav, kom ntseeg tau tias lub cuab yeej tsuas yog teb thaum tsim nyog. Tsis tas li ntawd, qee cov qauv AFDD siab heev suav nrog cov integrated circuit breakers, ntxiv txhim kho kev nyab xeeb ntawm lub tshuab hluav taws xob.
Kev teeb tsa cov khoom siv nrhiav qhov teeb meem arc hauv cov chaw nyob, chaw ua lag luam thiab chaw ua haujlwm yog qhov tseem ceeb heev rau kev tiv thaiv hluav taws xob. Lawv muaj txiaj ntsig zoo rau cov chaw uas muaj kev pheej hmoo ntau dua ntawm qhov teeb meem arc, xws li cov chaw uas muaj cov xov hlau qub lossis cov chaw uas muaj ntau yam khoom siv hluav taws xob. Los ntawm kev ntes thiab cuam tshuam qhov teeb meem arc thaum ntxov, AFDD txo qhov muaj feem yuav muaj hluav taws kub, ua rau cov tswv tsev thiab cov tswv lag luam muaj kev thaj yeeb nyab xeeb.
Hauv kev xaus lus, cov khoom siv kuaj pom qhov txhaum arc hloov pauv lub ntsej muag ntawm kev nyab xeeb hluav taws xob los ntawm kev kuaj pom thiab tiv thaiv qhov txhaum arc, yog li txo qhov kev pheej hmoo ntawm hluav taws xob. Nrog nws cov peev xwm saib xyuas siab heev thiab muaj peev xwm sib txawv ntawm cov arcs tsis muaj teeb meem thiab txaus ntshai,AFDDua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb ntawm cov chaw nyob thiab cov chaw ua lag luam. Nws yog ib qho tseem ceeb rau cov tib neeg thiab cov koom haum kom muab qhov tseem ceeb rau kev nyab xeeb hluav taws xob thiab xav txog kev teeb tsa cov khoom siv kuaj xyuas qhov txhaum arc los tiv thaiv lawv tus kheej, lawv cov khoom, thiab lawv cov neeg hlub ntawm cov txiaj ntsig loj heev ntawm hluav taws xob.
