Qhov tsis zoo ntawm kev ncaj qha tam sim no (DC) kuaj
(1) Tshwj tsis yog tsis muaj kev muaj peev xwm siv tau ntawm cov khoom ntsuas, ntsuas hluav taws xob yuav tsum tau pib los ntawm "XOOM" thiab sawv maj mam kom tsis txhob them ntau tam sim no. Qhov ntxiv voltage tseem qis dua. Thaum txoj kev them nyiaj tam sim no loj heev, nws yuav twv tsis ncaj ncees los ntawm tus tester thiab ua qhov kev sim ua kom tsis raug.
(2) Vim tias lub DC withstand kev ntsuas yuav them tus khoom siv hauv kev sim, qhov khoom kuaj yuav tsum tau tawm ua ntej ua rau kauj ruam tom ntej.
(3) Tsis zoo li AC Kuaj, DC withstand verticage ntsuas tsuas yog kuaj nrog ib qho polarity. Yog tias cov khoom lag luam yog siv nyob rau hauv Ac hauv AC Voltage, qhov tsis zoo no yuav tsum tau txais kev txiav txim siab. Qhov no tseem yog vim li cas thiaj li muaj kev nyab xeeb rau kev nyab xeeb rau kev siv AC wallage ntsuas.
(4) Thaum lub sijhawm AC woldpress kuaj, lub ncov siab ntawm cov ntsuas hluav taws xob, thiab tseem tsis tuaj yeem ua tiav los ntawm DC wallage ntsuas. Yog li no, cov kev nyab xeeb tshaj plaws yuav tsum tau hais tias yog DC withstand kev ntsuas yog siv, yuav tsum tau nce ntxiv rau tus nqi sib npaug.
Tom qab DC withstand cov kev ntsuas tiav lawm, yog tias tus kwv nyob hauv qab yuav tsis raug rho tawm, nws yog qhov yooj yim los ua rau hluav taws xob rau tus neeg teb xov tooj; Txhua peb DC withstand voltage kuaj muaj kev tshem tawm sai sai muaj nuj nqi ntawm 0.2s. Tom qab DC withstand cov kev ntsuas tiav lawm, tus tester nws tuaj yeem tso hluav taws xob ntawm lub cev sim tsis pub dhau 0.2s tiv thaiv kev nyab xeeb ntawm tus neeg teb xov tooj.
Taw qhia rau qhov zoo thiab qhov tsis zoo ntawm AC withst voltage kuaj
Thaum lub sij hawm tiv thaiv kev kuaj, tus siv hluav taws xob siv rau hauv lub cev ntsuas hluav taws xob rau lub cev ua haujlwm los ntawm 2 thiab ntxiv 1000V. Piv txwv li, kev ua haujlwm voltage ntawm ib qho khoom sim yog 220V, thaum lub tshuab hluav taws xob tau ua, qhov hluav taws xob ntawm cov ntsuas hluav taws xob yog 220V + 1440V, feem ntau 1500v.
Lub withstand kev xeem tau muab faib ua ib AC withstand voltage kuaj thiab DC wallage ntsuas; Qhov zoo thiab qhov tsis zoo ntawm AC wallage ntsuas yog raws li hauv qab no:
Qhov zoo ntawm AC withstt voltage kuaj:
(1) Feem ntau hais lus, ACTIC AC qhov ntsuas tau yooj yim yuav tsum tau txais los ntawm chav nyab xeeb dua li DC TEST. Qhov laj thawj tseem ceeb yog tias feem ntau ntawm cov khoom siv hloov pauv tam sim no, thiab kev ntsuas qib tam sim no tuaj yeem kuaj qhov zoo thiab tsis zoo nrog rau ib puag ncig uas cov khoom siv tau thiab yog nyob hauv kab nrog kev siv qhov xwm txheej tiag tiag.
(2) Vim tias cov ntoo stray tsis tuaj yeem raug them tag nrho thaum lub ntsuas hluav taws xob tam sim no, yog li tsis tas yuav muaj qhov ntsuas hluav taws xob maj mam tuaj yeem maj mam tuaj yeem ntxiv thaum pib ntawm Ntsuam xyuas, tshwj tsis yog cov khoom lag luam rhiab rau hauv inrush voltage rhiab heev.
(3) Vim tias AC qhov ntsuas tsis tuaj yeem sau cov hluav taws xob plawm, tsis tas yuav tso cov khoom ntsuas tomqab kuaj tomqab kuaj, uas yog lwm qhov zoo dua.
Qhov tsis zoo ntawm AC withstt voltage kuaj:
(1) Lub ntsiab tseem ceeb yog tias cov pluaj pluaj ntawm cov khoom ntsuas ntsuas yog qhov kev ntsuas khoom tam sim no, yog li tsis tuaj yeem paub tam sim no. tam sim no.
(2) Lwm qhov chaw tsis zoo yog tias txij li qhov kev tsim hluav taws xob uas muaj peev xwm ua tau zoo ntawm lub tshuab yuav tsum tau loj dua li tam sim no thaum siv DC sim. Qhov no ua rau muaj kev pheej hmoo rau tus neeg teb xov tooj.
Puas muaj qhov sib txawv ntawm kev kuaj arc thiab kuaj tam sim no?
1. Hais txog kev siv Arc nrhiav haujlwm (ARC).
a. ARC yog lub cev tshwm sim, tshwj xeeb ib txwm nquag pulsed voltage.
b. Kev Txwv Ntau Yam: Ib puag ncig cuam tshuam, kev cuam tshuam rau kev cuam tshuam, kev cuam tshuam.
c. ARC muaj ntau thiab muaj kev txhawj xeeb los ntawm txhua tus neeg, thiab nws tseem yog ib qho ntawm cov xwm txheej tseem ceeb rau kev ntsuas cov khoom zoo.
d. RK99 Series Program-tswj hwm nrog Voltage kuaj tsim los ntawm peb lub tuam txhab muaj kev ua haujlwm ntawm kev kuaj arc. Nws piv txwv lub siab ntawm cov phiaj xwm ntau tshaj plaws saum toj kawg nkaus 10kHz los ntawm kev teb siab tshaj plaws ntawm 10kHz, thiab tom qab ntawd muab piv nrog ntsuas ntsuas ntsuas kom paub tseeb tias nws tsim nyog. Daim foos tam sim no tuaj yeem teeb tsa tau, thiab cov qib ntawv tuaj yeem tsim.
e. Yuav ua li cas xaiv cov kev paub txog qib qib yuav tsum tau teeb tsa los ntawm tus neeg siv raws li cov yam ntxwv khoom thiab cov kev xav tau.
