Nrog rau kev siv dav dav ntawm withstt voltage cov testers, ntau thiab ntau cov neeg tsim khoom siv hluav taws xob xaiv nrog cov khoom siv hluav taws xob thiab cov khoom lag luam khoom, thiab qee tus txawm siv los siv cov khoom siv rau kev siv tsheb. Cia peb tshawb xyuas cov yam ntxwv thiab daim ntawv teev cov lej ntawm FutAst cov ntsuas hluav taws xob nrog peb niaj hnub no.
Raws li rau FallAstand ntsuas, feem ntau ntawm lawv ntau tshaj li ib txhiab lossis ntau tshaj li ob txhiab ntawm kev ua lag luam. Lawv muaj ib qho haujlwm thiab ib hom. Peb lub tuam txhab tiv thaiv nrog cov voltage tester, cov ns2oo series, muaj ib tus neeg ywj pheej nrog cov ntsuas hluav taws xob. Kev ntsuas siab, plaub-channel siab tester, plaub-channel sab laug thiab sab xis mus zog tester, thiab ywj pheej channel siab tester. Txaus siab rau kev xaiv thiab daim ntawv thov ntawm cov neeg siv feem ntau.
Nta: Qhib kev sib txuas ua ke thiab cov chaw ua haujlwm luv luv nrhiav haujlwm, tib neeg lub cev tiv thaiv kev ua haujlwm, ARC nrhiav haujlwm. Thiab nws tuaj yeem ua ke ntau txoj hauv kev kom tsim tawm, thiab tuaj yeem txiav txim cov khoom ntawm txhua tus channel ywj siab.
Nrog rau voltage tester tuaj yeem muab faib ua hluav taws xob rouldulation tester, dielectric zog tester thiab lwm yam.
Tus txheej txheem ua hauj lwm ntawm FutAst totioner yog: Thov lub zog hluav taws xob ua haujlwm rau cov khoom siv insulator ntawm cov khoom siv hauv kev sim, thiab txuas ntxiv rau lub sijhawm ib txwm muaj. Qhov hluav taws xob thov rau nws tsuas yog ua rau muaj cov xau me me tam sim no, uas yog cov rwb thaiv tsev. Zoo dua.
Kev tswj hwm lub hwj chim muab hluav taws xob muab, teeb liab sau thiab xa cov teeb liab thiab cov txheej txheem tswj kev tswj hwm thiab kev tswj hwm kev tshuaj xyuas.
Xaiv 2 lub hom phiaj ntawm Fallage Tester: cov zis tshaj plaws voltage muaj nuj nqis thiab lub tswb yam siab.
Nrog rau kev txhim kho kev tsim khoom ntawm cov twj paj nruag siab, tshiab ntawm cov ntsiab lus siab thiab kev siv kev ua haujlwm tsis sib xws tseem txawv ntawm cov twj paj nruag. Nws yog ib qho tsim nyog rau txhua tus kws tshaj lij kev nyab xeeb kom nkag siab txog nws txoj kev ua haujlwm thiab siv FutAst tester kom raug.
Raws li cov tshuab hluav taws xob kev tshuaj xyuas yuav tsis muaj peev xwm ua rau hluav taws xob hluav taws xob, cov kev ceev faj hauv qab no yuav tsum tau ua raws li qhov yuav txo qis kev pheej hmoo. Qhov tseem ceeb ntawm kev nyab xeeb tshuaj ntawm hluav taws xob hluav taws xob thiab cov khoom hluav taws xob tau dhau los ua kom muaj kev nce qib, thiab kev txhim kho kev tawm tsam yog qhov rhiab heev.
1. Kev cob qhia theoretical rau cov neeg ua haujlwm thiab hu rau txhua txoj cai soj ntsuam;
2. Tshuaj xyuas thiab hloov kho tag nrho cov txheej txheem kev nyab xeeb;
3. Cais qhov chaw nyob ntawm kev kuaj mob lossis deb ntawm cov neeg ua haujlwm ntawm Rhiav;
4. Teeb kev thaiv kev uas tsis tuaj yeem hla hauv thaj chaw tshuaj xyuas;
5. Kom meej meej cov cim qhia tau qhia tias "kev phom sij" thiab "muaj siab" hauv qhov chaw tshuaj xyuas;
6. Ib qho cim pom meej meej qhia tias "cov neeg ua haujlwm tsim nyog tuaj yeem nkag mus" kom meej meej hauv thaj chaw tshuaj xyuas;
7. Xyuas kom meej pem hauv paus ntawm txhua yam khoom siv;
8. Tus neeg teb xov tooj xav tau ob txhais tes pib ua kev soj ntsuam cov cuab yeej, lossis cov khoom siv kev nyab xeeb thaum cov qauv kev nyab xeeb yog qhib;
9. Muab cov khoom siv los ua ke, uas tuaj yeem txiav cov khoom siv hluav taws xob zoo hauv cov xwm txheej ceev.
Kev txiav txim siab ntawm kev sim voltage ntawm Fallage Pester yuav tsum xa mus rau cov qauv kev nyab xeeb sib txawv. Yog tias qhov kev xeem voltage dhau dhau lawm, cov khoom siv insulating yuav dhau qhov kev xeem vim tias tsis muaj hluav taws xob thiab lub rwb thaiv tsev tsis muaj tseeb thiab tsis muaj peev xwm. Yog tias qhov hluav taws xob feem ntau dhau lawm, qhov kev sim yuav muaj insulated cov khoom ua rau muaj kev phom sij tas mus li tas mus li. Txawm li cas los xij, muaj ib txoj cai dav dav uas yog siv cov lus uas muaj kev paub: Kev ntsuas voltage = fais fab muab voltage × 2 + 1000000 Piv txwv li: lub zog muab voltage ntawm cov khoom xeem yog 120V, tom qab ntawd qhov kev xeem voltage = 120v × 2 + 1000v = 1240V. Hauv kev coj ua, hom no yog kuj yog tus qauv coj los ntawm cov qauv kev nyab xeeb feem ntau. Qhov laj thawj rau kev siv 1000V ua ib feem ntawm cov qauv ntawm cov khoom muaj sia ntawm txhua yam khoom yog cov kev cuam tshuam los ntawm kev hloov pauv siab ntau txhua hnub. Kuaj thiab kev tshawb fawb qhia tias qhov hluav taws xob hluav taws xob no tuaj yeem ncav cuag li 1000V.
