Ntxiv rau qhov yooj ywm, cov khoom siv hluav taws xob hloov kho tau tuaj yeem ua rau kom qhov tseeb ntawm cov hluav taws xob tiv thaiv. Lub peev xwm los kho qhov chaw teeb tsa kom zoo tso cai rau kev teb kom raug dua rau cov xwm txheej overcurrent, txo qhov kev pheej hmoo ntawm kev ua yuam kev thaum tseem tswj hwm kev tiv thaiv zoo. Qib kev tswj hwm no muaj txiaj ntsig zoo heev rau cov ntawv thov tseem ceeb uas kev sib koom tes meej thiab kev xaiv ua kom raug yog qhov tseem ceeb rau kev ntseeg siab tag nrho ntawm lub kaw lus hluav taws xob.
Ntxiv mus, qhov xwm txheej hloov kho tau ntawm lub tshuab hluav taws xob ua rau muaj kev hloov kho rau kev hloov pauv hauv qhov chaw hluav taws xob. Piv txwv li, thaum cov khoom siv hluav taws xob nce lossis txo qis, qhov chaw teeb tsa tuaj yeem hloov kho kom haum rau cov xwm txheej ua haujlwm tshiab, kom ntseeg tau tias lub tshuab hluav taws xob txuas ntxiv muab kev tiv thaiv zoo yam tsis cuam tshuam rau kev ua haujlwm ntawm lub kaw lus tag nrho. Qhov kev hloov kho no pab ua kom lub neej ntev thiab kev ua haujlwm zoo ntawm cov khoom siv hluav taws xob.
Lwm yam tseem ceeb ntawm lub tshuab hluav taws xob hloov tau yog nws lub peev xwm los hloov kho lossis nthuav dav rau lub tshuab hluav taws xob yav tom ntej. Thaum lub tshuab hloov zuj zus, qhov chaw teeb tsa tuaj yeem hloov kho dua kom haum rau cov kev xav tau tshiab, tshem tawm qhov xav tau hloov tag nrho lub tshuab hluav taws xob. Qhov kev nthuav dav no tsis yog tsuas yog ua kom yooj yim rau kev saib xyuas thiab kev txhim kho xwb, tab sis kuj txo cov nqi tag nrho ntawm kev muaj lub zog hluav taws xob.
Thaum xaiv lub tshuab hluav taws xob hloov kho tau, nws yog ib qho tseem ceeb uas yuav tsum xav txog cov kev cai tshwj xeeb ntawm daim ntawv thov, suav nrog hom kev thauj khoom hluav taws xob, ib puag ncig ua haujlwm thiab qib kev tiv thaiv uas xav tau. Tsis tas li ntawd, kev ua raws li cov qauv kev lag luam thiab cov cai yuav tsum tau txiav txim siab kom ntseeg tau tias cov tshuab hluav taws xob ua tau raws li cov qauv kev nyab xeeb thiab kev ua tau zoo.
Hauv kev xaus lus, cov cuab yeej hloov kho tau muab kev daws teeb meem ntau yam thiab hloov kho tau rau kev tiv thaiv cov circuits ntawm overcurrent thiab luv circuits. Nws qhov kev ywj pheej, kev ua kom raug, kev hloov pauv tau thiab kev nthuav dav ua rau nws zoo tagnrho rau ntau yam kev siv, los ntawm kev lag luam thiab kev lag luam mus rau kev teeb tsa hauv tsev. Cov cuab yeej hloov kho tau ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov kab ke hluav taws xob los ntawm kev muab lub peev xwm los hloov kho qhov chaw mus rau qhov xav tau tshwj xeeb.
