Hauv kev faib hluav taws xob qis, thaum qhov kev ua txhaum tam sim no tshwm sim nyob rau hauv theem qis qis, cov cuab yeej tiv thaiv qib siab tsis tuaj yeem tiv thaiv thiab tswj tau zoo. Raws li qhov tshwm sim, qhov loj ntawm qhov hluav taws xob tsis ua hauj lwm raug xwm txheej, txawm tias kev lag luam loj thiab cov neeg raug tsim txom, tau yog cov ncauj lus kawm tshaj plaws hauv cov khoom siv hluav taws xob tsawg, thiab kuj yog ib qho teeb meem qub uas tsis tau daws tau ntev. Yog li ntawd, nyob rau hauv lub tam sim no-voltage tis system tsim ua hauj lwm, nyob rau hauv thiaj li yuav txhim kho thiab ua kom muaj kev ruaj ntseg thiab kev cia siab ntawm cov khoom siv hluav taws xob, thiab tsis txhob muaj hluav taws kub los yog hluav taws xob shocks nyob rau hauv lub lag luam ntawm cov khoom siv hluav taws xob, cov neeg ua hauj lwm tau muab tso rau pem hauv ntej ntau yam kev daws teeb meem thiab cov tswv yim. hauv lawv txoj haujlwm, tshwj xeeb tshaj yog nyob rau hauv kev xaiv cov khoom siv tiv thaiv, lawv tau nqis peev ntau lub zog rau kev tshawb fawb thiab sau cov ntsiab lus, yog li ua kom ntseeg tau tias qhov zoo ntawm tag nrho cov haujlwm.
Tsawg voltage tiv thaiv apparatus plays lub luag hauj lwm tseem ceeb nyob rau hauv lub tam sim no-voltage tis system, thiab plays lub luag hauj lwm irreplaceable. Tshwj xeeb tshaj yog, cov cuab yeej tiv thaiv tseem ceeb rau kev faib kab ua txhaum kuj yog qhov txuas tseem ceeb kom tsis txhob muaj kev txhaum loj thiab kev puas tsuaj. Txog rau tam sim no, hauv kev txhim kho kev sib raug zoo, cov cuab yeej tiv thaiv hluav taws xob qis tau dhau los ua lub ntsiab lus tseem ceeb ntawm kev tshawb fawb hauv kev ua haujlwm ntawm cov neeg sab hauv. Nws tuaj yeem muab faib ua ob pawg: fuse thiab Circuit Court breaker.
Fuse yog ib qho kev ntsuas tseem ceeb rau kev tiv thaiv kev nyab xeeb hauv cov khoom siv hluav taws xob tsawg, thiab tseem muaj cov khoom siv hluav taws xob ntau tshaj plaws hauv cov khoom siv hluav taws xob tsawg. Nws yog dav siv hauv kev tiv thaiv kab hluav taws xob thiab cov khoom siv hluav taws xob tiv thaiv hauv kev ua haujlwm tam sim no. Feem ntau hais lus, cov fuses uas tsis tshua muaj hluav taws xob feem ntau yog ntsia rau ntawm cov hluav taws xob hluav taws xob lossis ntawm cov khoom siv hluav taws xob hluav taws xob. Thaum muaj kev txhaum tshwm sim hauv daim phiaj hluav taws xob lossis hauv kev ua haujlwm ntawm cov khoom siv hluav taws xob, lub fuse tuaj yeem raug txiav tawm raws sijhawm thiab ua haujlwm tau zoo, yog li tiv thaiv thiab tiv thaiv kev sib kis thiab nthuav dav ntawm qhov txhaum.
