Txawm hais tias tam sim no nws yog ib qho kev ntseeg siab tiv thaiv hluav taws xob tester, nyob rau hauv cov txheej txheem ntawm kev ua haujlwm, nws yuav ua rau muaj kev pheej hmoo rau cov neeg ua haujlwm vim qee qhov teeb meem xws li kev cuam tshuam ntawm cov neeg ua haujlwm lawv tus kheej lossis lub ntiaj teb sab nraud.Yog li ntawd, ob lub tuam txhab tshwj xeeb hauv kev tsim cov khoom siv hluav taws xob tiv thaiv hluav taws xob thiab cov chaw lag luam uas siv cov khoom siv hluav taws xob tiv thaiv hluav taws xob yuav tsum sim lawv qhov zoo tshaj plaws los tiv thaiv qhov tshwm sim ntawm cov kev pheej hmoo, Yog li yuav ua li cas txo qhov kev phom sij no?
Feem ntau hais lus, ntau lub high-end withstand voltage testers yog tsim los nrog embedded ntse anti-voltage hluav taws xob poob siab system.Cov kab ke no tseem hu ua ntse GFI luv luv.Nws tuaj yeem ntes tau raws li kev siv cov qauv tam sim no.Yog hais tias qhov teeb meem ntawm hluav taws xob poob siab thiab cov xau tshwm sim, tus tsim nyog tiv thaiv hluav taws xob tester yuav txiav tawm qhov hluav taws xob high-voltage tso tawm hauv ib millisecond, txhawm rau xyuas kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm.Yog li ntawd, nyob rau hauv tib txoj kev ua haujlwm, tus tsim nyog tiv thaiv voltage tester, tsuav yog tus neeg teb xov tooj tsis ua yuam kev ntau dhau, yuav tsis tshua tawm tsam tus neeg teb xov tooj hluav taws xob thiab lwm yam kev phom sij.
Txhawm rau tiv thaiv cov neeg siv khoom thiab cov neeg siv khoom, cov neeg tsim khoom ntawm kev ntsuas siab yuav tsum ua kom tiav ntau hom kev ntsuas kev nyab xeeb thaum lawv ua tiav cov khoom siv, txhawm rau xyuas kom meej tias cov khoom ua raws li kev lag luam specifications ntawm cov khoom tsim, kev ua haujlwm thiab cov txheej txheem specifications. .Nws suav nrog kev ntsuas hluav taws xob tiv thaiv, ntsuas hluav taws xob, thiab lwm yam kev ntsuas hluav taws xob yuav tsum tau ua ua ntej cov khoom raug teeb tsa los ntawm cov chaw tsim khoom, feem ntau yog tiv thaiv cov khoom tsis tsim nyog los ntawm kev teeb tsa rau hauv cov khoom thiab ua rau muaj kev phom sij.Txog tam sim no, cov chaw tsim khoom tsim nyog, nws cov khoom tsim, kev sim thiab lwm yam txheej txheem yuav tsum tau ua raws li ISO ntiaj teb cov qauv, thiab cov khoom kawg yuav tsum tau mus txog ISO ntiaj teb daim ntawv pov thawj cov qauv, uas yog hais, los ntawm cov khoom mus rau cov khoom tiav. yuav tsum ncav cuag ISO ntiaj teb daim ntawv pov thawj cov qauv zoo, tsuas yog nyob rau hauv txoj kev no peb tuaj yeem txhim kho cov hauv paus zoo ntawm cov kev phom sij.Yog lawm, kev siv cov khoom lag luam muaj feem xyuam, tab sis kuj tseem niaj hnub ua haujlwm ntawm kev cob qhia cov neeg ua haujlwm, tshiab yuav tsum nyob rau hauv kev saib xyuas ntawm cov neeg ua haujlwm qub uas muaj kev paub dhau los ua haujlwm, thiaj li tiv thaiv kom tsis txhob muaj kev pheej hmoo los ntawm kev ua haujlwm yuam kev.
1. Qhov zoo ntawm AC withstand voltage test yog dab tsi
Feem ntau, AC withstand voltage tester yog yooj yim dua kom tau txais kev txhawb nqa ntawm lub koom haum kev nyab xeeb tshaj li DC tiv thaiv voltage tester.Qhov laj thawj tseem ceeb yog tias feem ntau ntawm cov khoom kuaj yuav ua haujlwm nyob rau hauv AC voltage, thiab AC tiv thaiv qhov ntsuas hluav taws xob muab qhov zoo ntawm kev hloov ob lub polarities los siv siab rau lub rwb thaiv tsev, uas yog ze rau lub siab uas cov khoom yuav ntsib hauv kev siv tiag tiag.Vim tias qhov kev xeem AC yuav tsis them tus nqi thauj khoom, qhov kev nyeem tam sim no zoo ib yam los ntawm qhov pib ntawm daim ntawv thov voltage mus rau qhov kawg ntawm qhov kev xeem.Yog li ntawd, txij li tsis muaj teeb meem stabilization yuav tsum tau saib xyuas kev nyeem ntawv tam sim no, tsis tas yuav tsum tau nce qib voltage los ntawm kauj ruam.Qhov no txhais tau hais tias tshwj tsis yog cov khoom nyob rau hauv kev sim ntsuas qhov ntsuas tam sim ntawd, tus neeg teb xov tooj tuaj yeem siv tam sim ntawd qhov hluav taws xob tag nrho thiab nyeem tam sim no yam tsis tau tos.Vim tias qhov hluav taws xob AC yuav tsis them tus nqi thauj khoom, tsis tas yuav tsum tso cov khoom siv kuaj tom qab kuaj.
2. Dab tsi yog qhov teeb meem ntawm AC voltage tester?
Thaum kuaj capacitive load, tag nrho cov tam sim no muaj reactance tam sim no thiab to tam sim no.Thaum qhov kev tawm tsam tam sim no loj dua li qhov xau tam sim no, nws yuav nyuaj rau kev kuaj xyuas cov khoom uas muaj cov xau tam sim no ntau dhau.Thaum kuaj qhov loj capacitive load, tag nrho cov tam sim no xav tau yog loj dua li cov dej ntws tam sim no nws tus kheej.Vim tias tus neeg teb xov tooj tau ntsib nrog ntau dua tam sim no, qhov no yuav muaj kev phom sij ntau dua.
3. Dab tsi yog qhov zoo ntawm DC tiv thaiv qhov ntsuas hluav taws xob?
Thaum DUT tau them tag nrho, tsuas yog cov dej xau tiag tiag ntws.Qhov no ua rau DC tiv taus qhov ntsuas hluav taws xob kom pom tseeb qhov hluav taws xob tam sim no ntawm cov khoom hauv kev sim.Vim tias qhov them tam sim no luv luv, lub zog yuav tsum tau muaj ntawm DC tiv thaiv qhov ntsuas hluav taws xob feem ntau me dua li ntawm AC tiv thaiv hluav taws xob siv los ntsuas cov khoom qub.
4. Dab tsi yog qhov tsis xws luag ntawm DC tiv thaiv voltage tester?
Vim tias DC qhov hluav taws xob tiv thaiv kev ntsuas tsis them cov khoom hauv kev sim (DLT), txhawm rau tshem tawm qhov kev pheej hmoo ntawm hluav taws xob poob siab ntawm tus neeg teb xov tooj tuav cov khoom hauv kev sim (DLT) tom qab qhov ntsuas hluav taws xob tiv thaiv, cov khoom hauv kev sim (DLT) yuav tsum yog. tso tawm tom qab kuaj.Kev kuaj DC yuav them tus nqi capacitor.Yog tias DUT tiag tiag siv AC fais fab, DC txoj kev tsis simulate qhov tseeb.
