Txawm hais tias tam sim no yog tam sim no ib tug ntseeg tau worderworthy withstand ntsuas, nws yuav ua rau muaj qee yam teeb meem xws li cov teeb meem ntawm cov ua haujlwm lawv tus kheej lossis lub ntiaj teb sab nraud. Yog li ntawd, ob qho tib si to taub tshwj xeeb hauv kev tsim tawm nrog voltage kuaj thiab cov kev lag luam uas muaj tshwm sim ntawm cov kev pheej hmoo no, yog li yuav ua li cas txo qhov kev phom sij uas muaj kev phom sij li no?
Feem ntau hais lus, ntau qhov kev ncua siab nrog cov tshuaj voltage yog tsim nrog cov ntse anti high-voltage hluav taws xob system. Qhov system no tseem hu ua Smart GFI luv luv. Nws tuaj yeem ntes raws li kev siv cov qauv tam sim no. Yog tias qhov teeb meem ntawm hluav taws xob hluav taws xob thiab xau dej tau pom zoo, tus tsim nyog txiav tawm cov kev tawm tsam siab hauv ib lub millisecond, kom ntseeg tau tias kev nyab xeeb ntawm cov neeg ua haujlwm. Yog li ntawd, nyob rau hauv tib txoj haujlwm kev ua haujlwm, muaj ib qho kev tsim nyog nrog voltage kuaj, ntev npaum li tus neeg teb xov tooj tsis ua yuam kev, yuav tsis tshua tawm tsam tus neeg teb xov tooj hluav taws xob hluav taws xob thiab lwm yam kev phom sij.
Txhawm rau tiv thaiv cov neeg siv khoom thiab cov haujlwm ntawm cov khoom lag luam uas tau tsim cov qauv kev nyab xeeb, kom ua tiav cov qauv kev nyab xeeb, yog li ua tiav cov qauv kev lag luam, muaj nuj nqi thiab kev ua haujlwm thiab cov txheej txheem tshwj xeeb Cov. Nws suav nrog cov hluav taws xob tiv thaiv, rwb thaiv tsev kuaj, thiab lwm yam. Lub rwb thaiv tsev tsis muaj kev cuam tshuam rau hauv cov khoom lag luam thiab ua rau muaj kev phom sij. Tam sim no, cov chaw tsim nyog tsim nyog, nws cov khoom lag luam thiab lwm cov txheej txheem yuav tsum tau mus txog ISO ntiaj teb cov qauv ntawv, uas yog hais, los ntawm ntu ua tiav cov khoom tiav Yuav tsum mus txog Iso World Cov Ntawv Pov Thawj Ua Haujlwm Zoo, tsuas yog txoj hauv kev no peb tuaj yeem ua kom zoo tshaj tawm cov kev phom sij. Yog lawm, kev siv cov khoom siv cuam tshuam nrog, tab sis kuj tau npaj ua haujlwm ntawm cov neeg ua haujlwm uas tau ua haujlwm tshiab, thiaj li los tiv thaiv qhov tsis muaj kev pheej hmoo los ntawm kev ua haujlwm tsis raug.
1. Dab tsi yog qhov zoo ntawm AC withst voltage kuaj
Feem ntau, AC withstt cov volter yog yooj yim kom tau txais kev txhawb nqa lub koom haum kev nyab xeeb dua li DC withstand voltage Schaer. Qhov laj thawj tseem ceeb yog feem ntau ntawm cov khoom kuaj yuav ua haujlwm nyob rau hauv ob lub xees ntawm kev txhawb nqa ob leeg los ze zog rau lub siab uas cov khoom lag luam yuav ntsib hauv kev siv tiag tiag. Vim tias AC qhov kev xeem yuav tsis them tus nqi thauj khoom, nyeem ntawv tam sim no yog pib thaum pib cov ntawv thov voltage mus txog thaum kawg ntawm kev xeem. Yog li ntawd, vim tias tsis muaj teeb meem ruaj khov yuav tsum tau saib txoj kev nyeem ntawv tam sim no, tsis tas yuav nce cov kauj ruam voltage los ntawm kauj ruam. Qhov no txhais tau tias tshwj tsis yog cov khoom lag luam nyob rau hauv kev ntsuam xyuas tam sim ntawd siv voltage, tus neeg teb xov tooj yuav siv tau tag nrho cov hluav taws xob thiab nyeem cov tam sim no tsis muaj tos. Vim tias AC voltage yuav tsis them tus nqi, tsis tas yuav tso cov khoom siv kuaj tom qab sim.
2. Dab tsi yog qhov tsis xws luag ntawm AC voltage tester?
Thaum muaj peev xwm ntsuas tau yog kuaj, tag nrho cov tam sim no muaj cov reflets ntawm recharance tam sim no thiab dej xau tam sim no. Thaum cov tsis kam tam sim no yog ntau dua qhov xau dej tam sim no, nws yuav nyuaj rau ntes cov khoom uas muaj kua dej ntau dhau. Thaum kuaj cov hluav taws xob loj thauj khoom, qhov kev xav tau tag nrho tam sim no yog ntau dua qhov xau xau tam sim no nws tus kheej. Vim tias tus neeg teb xov tooj ntsib nrog ntau qhov tam sim no, qhov no yuav yog qhov txaus ntshai dua.
3. Dab tsi yog qhov zoo ntawm DC withst quab yuam?
Thaum lub hnub ua tau raug them tag nrho, tsuas yog muaj lub pas dej tiag tiag ntws. Qhov no ua rau DC withstand ntsuas ntsuas ntsuas kom pom meej cov khoom seem tam sim no ntawm cov khoom lag luam. Vim tias txoj kev them nyiaj tam sim no luv, lub zog yuav tsum tau ua kom muaj voltage satter feem ntau yog ntau dua li AC withstt cov tshuaj ntsuam siv los sim tib yam khoom.
4. Dab tsi yog qhov tsis xws luag ntawm DC withstand voltage Schaer?
Vim hais tias DC cov hluav taws xob withst xeem tau them tus nqi ntawm cov khoom lag luam (LLT) tso tawm tom qab qhov kev xeem. Qhov ntsuas DC yuav them tus capacitor. Yog tias lub dut yeej siv AC lub zog, DC txoj kev tsis simulate qhov xwm txheej tiag tiag.
