Kuv Lub Tebchaws tau dhau los ua lub hauv paus loj tshaj plaws hauv ntiaj teb rau cov khoom siv hauv tsev thiab cov khoom siv hluav taws xob thiab hluav taws xob, thiab nws cov khoom xa tawm tseem nce ntxiv.Ua ke nrog cov neeg siv khoom 'kev nyab xeeb khoom, nyob rau hauv txoj kab nrog cov kev cai thoob ntiaj teb thiab cov kev cai, cov neeg tsim khoom txuas ntxiv txhim kho cov qauv kev nyab xeeb ntawm cov khoom.Tsis tas li ntawd, Cov Chaw Tsim Khoom kuj tseem them nyiaj tshwj xeeb rau kev soj ntsuam kev nyab xeeb ntawm cov khoom ua ntej tawm hauv lub Hoobkas.Nyob rau lub sijhawm no, kev nyab xeeb ntawm cov khoom siv hluav taws xob ntawm cov khoom, tej zaum muaj kev nyab xeeb tiv thaiv hluav taws xob, yog ib qho tseem ceeb heev rau cov khoom kuaj nyob rau lub sijhawm no.
Txhawm rau kom nkag siab txog cov khoom siv hluav taws xob rwb thaiv tsev, cov khoom lag luam npaj, cov qauv, thiab cov khoom siv rwb thaiv tsev muaj cov kev qhia tshwj xeeb lossis cov kev qhia tshwj xeeb.Feem ntau, cov neeg tsim khoom yuav siv ntau txoj hauv kev los kuaj lossis kuaj.Txawm li cas los xij, rau cov khoom siv hluav taws xob, muaj ib hom kev sim uas yuav tsum tau ua, uas yog-Dielectric Withstand Test, qee zaum hu ua Hipot Test lossis Hipot Test, High Voltage Test, Hluav Taws Xob Test, thiab lwm yam Cov Kev Ntsuas Hluav Taws Xob ntawm General Cov khoom zoo los yog phem;Nws tuaj yeem cuam tshuam los ntawm Kev Ntsuas Hluav Taws Xob.
Muaj ntau ntau hom kev tiv thaiv hluav taws xob hauv khw tam sim no.Raws li cov neeg tsim khoom muaj kev txhawj xeeb, yuav ua li cas kom txuag tau peev peev thiab lawv tus kheej xav tau kev yuav khoom siv nrog cov ntsuas hluav taws xob tau dhau los ua qhov tseem ceeb dua.
1. Hom Kev Ntsuas Hluav Taws Xob (Kev Sib Txuas Lus lossis DC)
Cov kab ntau lawm tiv thaiv qhov ntsuas hluav taws xob, qhov kev xeem dhau los (Routine Test), Raws li cov khoom sib txawv, muaj kev sib txuas lus tiv thaiv qhov ntsuas hluav taws xob thiab DC tiv thaiv qhov ntsuas hluav taws xob.Pom tseeb, Kev Sib Txuas Lus Nrog Kev Ntsuas Hluav Taws Xob yuav tsum xav txog seb qhov zaus ntawm qhov ntsuas qhov ntsuas hluav taws xob zoo li cas nrog kev ua haujlwm zaus ntawm cov khoom kuaj;Yog li ntawd, Qhov Muaj Peev Xwm Txaus Siab Xaiv Hom Kev Ntsuas Hluav Taws Xob thiab Kev Xaiv Yooj Yim Ntawm Kev Sib Txuas Lus Sib Txuas Lus yog Cov Haujlwm Tseem Ceeb Ntawm Cov Hluav Taws Xob Hluav Taws Xob..
2. Kev ntsuas qhov ntsuas hluav taws xob
Feem ntau, qhov tso zis ntsuas ntawm qhov ntsuas hluav taws xob ntawm kev sib txuas lus nrog hluav taws xob ntsuas ntsuas yog 3KV, 5KV, 10KV, 20KV, Thiab txawm tias siab dua, thiab qhov tso zis hluav taws xob ntawm DC tiv thaiv qhov ntsuas hluav taws xob yog 5KV, 6KV lossis txawm siab dua 12KV.Tus neeg siv yuav xaiv qhov tsim nyog qhov ntsuas hluav taws xob li cas rau nws daim ntawv thov?Raws li cov khoom sib txawv, qhov ntsuas hluav taws xob ntawm cov khoom muaj cov cai tswj kev nyab xeeb.Piv txwv li, Hauv IEC60335-1: 2001 (GB4706.1), Qhov Kev Ntsuas Hluav Taws Xob ntawm Kev Ua Haujlwm Kub Kub muaj qhov ntsuas tus nqi rau qhov ntsuas hluav taws xob.Hauv IEC60950-1: 2001 (GB4943), Kev Ntsuas Hluav Taws Xob Ntawm Cov Hluav Taws Xob Hluav Taws Xob kuj tau taw qhia.
Raws li Cov Khoom Siv thiab Cov Kev Qhia Kom Zoo, Kev Ntsuas Hluav Taws Xob kuj txawv.Hais txog Lub Tuam Txhab Tuam Txhab Kev Xaiv 5KV Thiab DC 6KV Nrog Kev Ntsuas Hluav Taws Xob, Nws tuaj yeem ua tau raws li qhov xav tau, tab sis hais txog qee lub koom haum kuaj tshwj xeeb lossis cov neeg tsim khoom txhawm rau txhawm rau teb cov khoom sib txawv, nws yuav tsum xaiv cov khoom siv 10KV thiab 20KV. Kev sib txuas lus lossis DC.Yog li ntawd, Muaj peev xwm tswj tau qhov tso zis hluav taws xob kuj tseem yog qhov yuav tsum tau muaj ntawm Kev Tiv Thaiv Voltage Tester.
3. Lub Sijhawm Quiz
Raws li cov khoom Specifications, General Withstand Voltage Test yuav tsum tau 60 vib nas this thaum lub sij hawm.Qhov no yuav tsum tau ua nruj me ntsis hauv cov koom haum soj ntsuam kev nyab xeeb thiab cov chaw ua haujlwm hauv Hoobkas.Txawm li cas los xij, Qhov Kev Ntsuas Zoo li no yuav luag tsis muaj peev xwm ua tau raws li cov kab ntau lawm thaum lub sijhawm.Lub hom phiaj tseem ceeb yog nyob rau kev ceev ceev thiab kev ua haujlwm ntawm kev tsim khoom, yog li kev sim mus sij hawm ntev tsis tuaj yeem txaus siab rau cov kev xav tau.Hmoov zoo, Ntau lub koom haum tam sim no tso cai xaiv kom luv lub sij hawm xeem thiab nce qhov ntsuas hluav taws xob.Tsis tas li ntawd, Qee Txoj Cai Kev Nyab Xeeb Tshiab kuj tseem qhia meej txog lub sijhawm xeem.Piv txwv li, Hauv Cov Lus Qhia Ntxiv A Ntawm IEC60335-1, IEC60950-1 Thiab Lwm Cov Kev Qhia Tshwj Xeeb, Nws tau hais tias Kev Xeem Routine (Routine Test) Lub Sijhawm yog 1sec.Yog li ntawd, qhov teeb tsa ntawm Lub Sij Hawm Kev Ntsuas kuj tseem yog ib qho tseem ceeb ntawm Kev Tiv Thaiv Voltage Tester.
Plaub, Qhov Voltage Slow Rise Function
Ntau yam kev tswj hwm kev nyab xeeb, xws li IEC60950-1, piav qhia cov yam ntxwv tso zis ntawm qhov ntsuas hluav taws xob raws li hauv qab no: "Kev ntsuas hluav taws xob siv rau lub rwb thaiv tsev hauv kev ntsuas yuav tsum maj mam nce ntawm xoom mus rau qhov ntsuas hluav taws xob tsis tu ncua ...";IEC60335-1 Cov lus piav qhia hauv: "Thaum pib ntawm qhov kev sim, qhov kev siv hluav taws xob tsis dhau ib nrab ntawm tus nqi hluav taws xob tsis tu ncua, thiab tom qab ntawd maj mam nce mus rau tag nrho tus nqi."Lwm Txoj Cai Kev Nyab Xeeb kuj tseem muaj cov kev xav tau zoo sib xws, uas yog, qhov hluav taws xob tsis tuaj yeem siv tam sim ntawd rau cov khoom ntsuas, thiab yuav tsum muaj cov txheej txheem qeeb qeeb.Txawm hais tias Cov Lus Qhia Tshwj Xeeb Tsis Muaj Cov Lus Qhia Kom Paub Txog Lub Sijhawm Ntxiv rau qhov kev nthuav dav qeeb qeeb, nws lub hom phiaj yog txhawm rau tiv thaiv kev hloov pauv sai.High Voltage yuav ua rau lub rwb thaiv tsev muaj nuj nqi ntawm cov khoom ntsuas.
Peb paub tias qhov ntsuas qhov ntsuas hluav taws xob yuav tsum tsis yog qhov kev sim ua kom puas tsuaj, tab sis yog ib qho kev kuaj xyuas cov khoom tsis raug.Yog li ntawd, Tus Txhaum Voltage Tester yuav tsum muaj qhov ua haujlwm qeeb qeeb.Tau kawg, yog tias pom muaj qhov txawv txav thaum lub sij hawm nce qeeb, cov cuab yeej yuav tsum tuaj yeem nres tam sim ntawd, yog li ntawd qhov kev sib xyaw ua ke ua rau lub luag haujlwm vivid.
Tsib, Kev Xaiv Kev Xeem Tam Sim No
Los ntawm cov kev xav tau saum toj no, peb tuaj yeem pom tias, qhov tseeb, qhov yuav tsum tau muaj ntawm Cov Kev Cai Tswj Xyuas Kev Nyab Xeeb Txog Kev Tiv Thaiv Voltage Tester yeej muab cov kev xav tau meej dua.Txawm li cas los xij, Lwm qhov kev txiav txim siab hauv kev xaiv qhov ntsuas qhov ntsuas hluav taws xob yog qhov ntsuas ntawm qhov ntsuas tam sim no.Ua ntej qhov kev sim, Nws yog qhov tsim nyog los teeb tsa qhov kev sim ntsuas hluav taws xob, lub sijhawm sim thiab txiav txim siab tam sim no (Lub Sij Hawm Tshaj Lij Tshaj Lij Tshaj Tawm tam sim no).Cov tam sim no tiv taus qhov ntsuas hluav taws xob ntawm Kev Ua Lag Luam Siv Kev Sib Txuas Tam Sim No Ua piv txwv.Qhov siab tshaj plaws qhov hluav taws xob tam sim no uas ntsuas tau yog kwv yees li ntawm 3mA txog 100mA.Tau kawg, qhov siab dua qhov ntsuas qhov ntsuas qhov ntsuas tam sim no, qhov siab dua tus txheeb ze.Tau kawg, Ntawm no peb ib ntus xav txog qhov ntsuas qhov tseeb tam sim no thiab kev daws teeb meem ntawm tib theem!Yog li, Yuav Ua Li Cas Xaiv Ib Lub Cuab Yeej Zoo Rau Koj?Ntawm no, Peb kuj tseem nrhiav qee cov lus teb los ntawm Cov Lus Qhia.
Los ntawm cov lus qhia hauv qab no, peb tuaj yeem pom yuav ua li cas Qhov Kev Ntsuas Hluav Taws Xob tau txiav txim siab hauv cov lus qhia:
