Nangona zombini Uvavanyo lwe-Voltage Test kunye nokuvuza kwangoku kuVavanyo lunokusetyenziselwa ukuvavanya amandla e-Insulation yeThagethi evavanyiweyo, kukho iiyantlukwano eziphambili kwinkqubo yovavanyo kunye neziphumo.Uvavanyo lwe-Voltage Test lwenziwa phantsi koMbane oPhezulu emva kokuba i-Insulation System yazo zonke iiNdawo ezithweleyo zangoku zeThagethi eVavanyiweyo i-Short-Circuited.Uvavanyo lwangoku lokuvuza (Touch Current) lwenziwa phantsi kweeMeko zoMbane kusetyenziswa izixhobo zoMfuniselo ukuxelisa i-Impedance yoMzimba woMntu.
Nangona ezi Mvavanyo zimbini zahlukile, ziluncedo kakhulu ekuqinisekiseni uKhuseleko lweMveliso.Uvavanyo lwe-Winkstand Voltage luvavanyo lwe-100% yeRoutine (RoutineTest), kunye noVavanyo lwangoku lokuvuza lujongwa njengoVavanyo loHlobo.
Ngokwamkelwa ngokubanzi kweziKhokelo zanamhlanje ezisezantsi zombane (LVD), ukumelana novavanyo lombane kunye nokuvuza iimvavanyo zangoku ziya kuba ziimvavanyo ezisemgangathweni zoMveliso weMveliso, kunye novavanyo olongezelelekileyo, olunje ngovavanyo lokuxhathisa i-Insulation kunye novavanyo lokuxhathisa umhlaba, luya kongezwa.
IiMveliso zoMbane ezikwiMgangatho oPhezulu kufuneka ziPase uVavanyo lwemiGangatho yoKhuseleko kwimiba emininzi, kubandakanywa noVavanyo lweVolthage, uVavanyo lwe-Insulation Resistance, uVavanyo lweGround Impedance, ukuvuza kwangoku (uVavanyo lwangoku, njl.njl. Kwezi Zinto zoVavanyo loMgangatho woKhuseleko, iNxalenye eyiNgxaki kukuvuza. Uvavanyo lwangoku (Touch Current Test).Le Mveliso inokulinganisa ukuvuza okungaqhelekanga ngoku Ngokuvuza kuVavanyo lwangoku.Ukuvuza kwangoku Tester Sisixhobo esiqhelekileyo soVavanyo lokuvuza kuVavanyo lwangoku.
Uvavanyo lwe-Operation Leakage yangoku (Touch Current).
Kwiminyaka yakutshanje, iMithetho emininzi yoKhuseleko lweMveliso ifuna ukuba iiMveliso zivavanyelwe ukuvuza kwangoku, nokuba kuVavanyo loYilo lweMveliso okanye kuVavanyo loMveliso woMveliso, ngakumbi kwiSigaba soYilo.Emva kolu Mvavanyo, iiNjineli zoYilo lweeMveliso ziFumana ulwazi oluninzi oluBalulekileyo malunga neMveliso yeMveliso, ukwenza iMveliso ihambelane ngakumbi neMimiselo yoKhuseleko.Xa ithagethi eVavanyiweyo iVavanywa phantsi kweVoltage eyongezelelweyo okanye amaxesha angama-1.1 eSiphumo seVoltage eyoNgezelelweyo rhoqo, oko kukuthi, xa imveliso ivavanywa phantsi kosetyenziso oluyinyani kunye neemeko ezigwenxa, kuvavanyo lwangoku lokuvuza, iNcingo ephantsi yeThagethi evavanyiweyo. Ilinganisiwe ukuze kuqinisekiswe ukuHamba kuBuyiselwa ngoku ukuya kumgca ongathathi hlangothi weNkqubo.Kuvavanyo lwangoku lweKhabhinethi lokuvuza, okukhoyo ngoku ukusuka kumanqaku ahlukeneyo kwiKhabhinethi ukuya kwindawo engathathi hlangothi yeNkqubo iyalinganiswa.
Ukumelana ne-Voltage (I-Insulation) Umfuniselo kukuxelisa iNkqubo ye-Insulation yenjongo evavanyiweyo kufuneka ikwazi ukumelana nombane oPhezulu ngeXesha elithile phantsi kweeMeko ezingaphaya kosetyenziso oluQhelekileyo.IMveliso yokumelana noVavanyo lweVoltage ithetha ukuba inokusebenza ngokukhuselekileyo kusetyenziso oluQhelekileyo kwaye inokumelana noTshintsho oluQhelekileyo loTshintsho.Olu luVavanyo oluSebenzisayo jikelele, kwaye abavelisi beeMveliso banokulusebenzisa kwakhona ukuQinisekisa uphawu loMgangatho olusisiseko soMsebenzi weMveliso.
KwiNdibaniselwano yoVavanyo oluLula, uQhagamshelwano phakathi koMvavanyi weVoltage kunye neThagethi eVavanyiweyo inokudlula kwiBhokisi yeSokethi okanye iNkokheli yoVavanyo, kwaye emva koko uMvavanyi weVoltage wokumelana nokusebenzisa iVoltage kwiThagethi eVavanyiweyo.Ukuba i-Leakage edlulayo yangoku iKhulu kakhulu, i-Wildstand Voltage Tester iya kubonisa iintsilelo, ebonisa ukuba iTagethi eVavanyiweyo ayizange iphumelele uvavanyo.Ukuba Akukho Kuvuza Kugqithisileyo Ngoku Kuvavanyiweyo, Umvavanyi Wokumelana Nombane Uya Kubonisa Ukuba Idlulile Ngoku, Ebonisa Ukuba Ujoliso Oluvavanyiweyo Luluphumelele Uvavanyo.Ixabiso lokuvuza okugqithisileyo kwangoku limiselwa lixabiso elimiselweyo leNqanaba eliphezulu elivumelekileyo langoku, elinokulungelelaniswa kuMhloli weVoltage ukuze kuqinisekiswe ukuba uvavanyo lugqithile na.Umvavanyi weVoltage wokumelana ngokwenene ugxile kwiDinga le-Insulation phakathi kwee-Conductors ezithwalayo ngoku kunye nee-Conductors ezingathwaliyo ngoku, ezinje ngeZinyithi eziveziweyo ezingathwaliyo.Le yiNdlela elungileyo yokufumana iingxaki zoYilo lweMveliso, njengokubeka iiConductor kufutshane kakhulu.
IiMeko zokuSebenza kuVavanyo lweVoltage yeProgrammable Leakage Current Tester
Ukuvuza okuLawulwayo yiNkqubo yangoku yoMvavanyi ngokuBanzi, IiNkcazelo zoKhuseleko kunye neMibutho eLawulayo ayinayo Ixabiso elilinganisiweyo loVavanyo oluQhelekileyo loxinzelelo, kodwa imiselwe nguMvelisi weMveliso evavanyiweyo.Ukuba elona xabiso liphezulu lokumelana nokuvuza kweVoltage alichazwanga, *Indlela yoVavanyo eLungileyo kukuSeta iVoltage Leakage yangoku efikelela kwiNqanaba lokuHamba, eliPhezulu kancinci kunexabiso loVavanyo ekujoliswe kulo Valiwe phantsi kovavanyo.
Ukumelana nokuvuza kweVolthaji yangoku * IiNgcaciso zoKhuseleko ngokuBanzi kunye neeNgcaciso zinokuBhekela kwiiNgcaciso ezininzi ze-UL, Ngokubanzi "120k Ohm" njengeNgcaciso.Le Nkcazo iSeta ukuchasana okuFixed, okuya kukhokelela ngokuqinisekileyo kwiSibonakaliso seFault in the Withstand Voltage Test.Kwinqanaba lokuqala, iiVolts eziyi-1000 kunye neVoltage eyongezelelweyo kabini yeSixhobo esikwicala leQuilt.Esi siSiseti esiQhelekileyo sokumelana novavanyo lombane.Ukusukela ukuba iVoltage eyoNgezelelweyo kuninzi lweeThagethi zoVavanyo eziSetyenzisiweyo eMelika li-120
Kuvavanyo lwangoku lokuvuza, umlinganiselo wangoku ungasetyenziselwa ukubala iXabiso eliqikelelweyo loSeto loHambo lwangoku lokumelana noVavanyo lweVoltage.Oku kuphela lixabiso eliqikelelweyo, ngenxa yokutenxa kweZixhobo zeZixhobo kunokubangela iiyantlukwano eziNcinci ekuvuzeni kokuFunda okukhoyo kweeThagethi ezohlukeneyo zoVavanyo.Xa ubala iSetingi zangoku zokuvuza, kubaluleke kakhulu ukuqonda umahluko osisiseko phakathi kovavanyo lwe-Voltage kunye nokuvuza kovavanyo lwangoku.Nangona uninzi lwabavavanyi abavuzayo bangoku babonelela ngeeMvavanyo zokuPhuma (L/N) zokuTshintsho, balinganisa kuphela ukuvuza kwangoku ukusuka kwiNqanaba eliQinisekayo langoku ukuya kwimeko yesixhobo phantsi kovavanyo kunye.Uvavanyo lokumelana novavanyo lweVoltage lulinganisa ukuvuza kwangoku kwaMacandelwana amabini akhoyo ngoku kunye, ngaloo ndlela ebonisa ukuvuza okuPhezulu kokuFunda kwangoku.Umgaqo oluncedo kubhontsi kukuseta uHambo loVavanyo lweVolthage yangoku ukuya malunga ne-20% ukuya kwi-25% yesiphumo sobalo sale fomula ilandelayo:
(Ukumelana noVavanyo lweVoltage yeVoltage/Ukuvuza kwangoku uvavanyo lweVoltage) *Ukuvuza kovavanyo lwangoku = Ixabiso eliqikelelweyo lokumelana novavanyo lwangoku.
