Nyob rau hauv lub ntiaj teb ntawm hluav taws xob engineering, kev nyab xeeb tsis - kev sib ceg. Txhua lub cable, hloov pauv, hloov pauv, lossis lub cev muaj zog yuav tsum tau tiv thaiv kev ntxhov siab niaj hnub kev ua haujlwm txhua hnub, hnav ib puag ncig, lossis cov kev laus ib puag ncig. Nov yog qhov twgAC wall withstt voltage tester(Kuj tseem hu ua Hipot tester lossis ditefric sim tester) kauj ruam no yog, nws ua haujlwm li cas, thiab vim li cas nws yog lub pob zeb ntawm kev saib xyuas hluav taws xob thiab kev tsim hluav taws xob.
AC raws nraim li cas nrog Voltage Schaer ua?
Ntawm nws cov tub ntxhais, ib AC withstt cov tshuaj ntsuam yog tsim los xyuas cov cuab yeej siv hluav taws xob tsis tu ncua (AC) voltage tsis muaj tawg. Xav txog nws yog qhov "kev sim siab" rau rwb thaiv tsev rwb thaiv tsev.
Ntawm no yog lub hauv paus tseem ceeb: cov khoom siv hluav taws xob muab cov roj hmab, xws li roj) cais cov kev sib cais tam sim no (piv txwv li cov hluav taws xob luv luv lossis hluav taws xob luv luv lossis hluav taws xob luv luv). Sij hawm dhau los, rwb thaiv tsev tuaj yeem txwv vim kub, noo, kev ntxhov siab, lossis hluav taws xob overload. AC ZOOM TES TESER Siv cov tswj hwm tau siv ntau AC Voltage rau cov rwb thaiv tsev, simulating heev kev ua haujlwm los xyuas yog tias nws tuav. If the insulation fails (eg, through arcing or current leakage), the tester detects it-alerting technicians to potential hazards before they escalate.
Yuav ua li cas nws ua haujlwm: kev kawm txuj ci tom qab kev sim
Thaum cov qauv tsim sib txawv txawv, feem ntau AC wallage cov tub mus ua raws li cov haujlwm zoo sib xws:
1.
Voltage xaiv: Cov neeg ua haujlwm tau tsim cov tshuaj ntsuam xyuas qhov xav tau (piv txwv li, 1KV, 5kV, lossis siab dua, nyob ntawm cov khoom siv) thiab sijhawm li 1-5 feeb). Cov qauv xws li iec 60034 lossis IEEE C57.12.00 feem ntau sau cov cwjpwm no.
2.
Ramp -} nce theem: Tus tes taw maj nce cov zis voltage los ntawm xoom mus rau theem phiaj. Qhov no qeeb qeeb ramp tiv thaiv ib qho kev sim sai uas tuaj yeem ua rau qhov kev sim tsis muaj yam tsis tsim nyog.
3.
TEEV THEEM: Thaum lub hom phiaj voltage tau mus txog, nws tau tswj hwm rau lub sijhawm. Nyob rau lub sijhawm no, tus tester tsis tu ncua saib xyuas ob yam:
•
To tam sim no: Txawm tias kev ua haujlwm zoo rau lub cev me me rau ib qho tam sim no rau "xau" los ntawm. Kev lim dej ntau dhau yog qhia tau cov rwb thaiv tsev.
•
TUAG TUAG: Yog tias cov rwb thaiv tsev tshaj li cov rwb thaiv tsev qhov tawg tau yooj yim, tam sim ntawd surge nyob rau hauv tam sim no (lossis pom arcing) cov cim tsis ua hauj lwm.
4.
Kev Tshawb Xyuas: Tom qab sim, cov cuab yeej siv tau lees paub tias "PASS" (rwb thaiv tsev muaj) lossis "swb" (puas los sis tsis muaj zog). Qee cov qauv qib siab sau cov ntaub ntawv rau cov ntawv ua haujlwm ua raws cai.
Qhov twg yog AC withstand voltage kuaj?
Cov sim no yog ubiquitous nyob rau hauv kev lag luam uas hluav taws xob kev nyab xeeb yog qhov kev nyab xeeb. Ntawm no yog peb cov xwm txheej ib txwm muaj:
•
Kev Tsim Kho Kom Haum Zoo: Ua ntej tawm hauv lub hoobkas, cov hloov pauv, lossis cabruit Court tej tog, lossis cables yog mus rau AC mus rau kom lawv ua tau raws li cov qauv kev lag luam. Piv txwv li, cov chaw nres tsheb kauj teb yuav kuaj txhua pob los lav nws tuaj yeem lis 10kv ac tsis swb.
•
Fais Fab Sib Tw Txij Nkawm: Cov kev siv hluav taws xob ntsuas qhov siab - voltage khoom zoo li transformers, switchear, thiab insulators. Lub tuam txhab hluav taws xob hauv cheeb tsam, piv txwv li ACTABLE ACT Wallable Tester thaum lub sijhawm hloov pauv ua ntej nws ua rau kev tawm tsam.
•
Cov Chaw Muaj Cov Vaj Tse: Cov ntaub ntawv nrog cov tshuab hnyav (piv txwv li, cov tshuab raj, compressors) cia siab rau cov kev ntsuas no kom tiv thaiv tsis tau cov nqi. Piv txwv ua zaub mov ua nroj tshuag, piv txwv, tuaj yeem sim nws qhov chaw tsim muaj zog txhua xyoo kom tsis txhob muaj nqi ntau lawm nres.
Vim li cas nws tseem ceeb tshaj qhov koj xav
Skipping A wallage kuaj yuav txuag lub sijhawm nyob rau hauv lub sijhawm luv luv, tab sis cov kev pheej hmoo hnyav. Ib qho kev sib tsoo ib zaug tuaj yeem ua rau:
•
Hluav Taws Xob Hluav Taws Xob: Arcing los ntawm cov rwb thaiv tsev tsis tau muaj peev xwm ua tau cov ntaub ntawv nyob ze.
•
Cuab Yeej Siv Khoom Puas: Ib qho kev puas tsuaj hauv ib qho kev tivthaiv (piv txwv li, transformer) tuaj yeem ua cascade rau hauv kab ke- dav tsis ua.
•
Kev Nyab Xeeb Kev Nyab Xeeb: Hluav taws xob hluav taws xob lossis arc flashes pose lub tsheej -}} har}}} phom sij txaus ntshai rau cov kws tshaj lij.
Los ntawm kev ntsuas tus rwb thaiv tsev muaj feem xyuam, cov lag luam tsis tsuas yog ua raws kev nyab xeeb (zoo li osha lossis IEC) tab sis kuj tiv thaiv lawv cov peev txheej thiab cov neeg ua haujlwm.
