Yuav ua li cas tawm tom qab DC withstand voltage test

Txoj kev tso tawm tom qab DC tiv thaiv qhov ntsuas hluav taws xob, thiab yuav ua li cas xaiv cov hluav taws xob tawm thiab cov pas nrig tawm:
(1) Ua ntej txiav tawm qhov hluav taws xob siab hluav taws xob.
(2) Thaum qhov hluav taws xob ntawm tus qauv yuav tsum tau kuaj poob qis dua 1/2 ntawm qhov ntsuas hluav taws xob, tso cov qauv mus rau hauv av los ntawm qhov tsis kam.
(3) Thaum kawg, qhov tso tawm yog ncaj qha hauv av.
(4) Rau cov qauv uas muaj peev xwm loj, xws li cov cables ntev, cov khoom siv hluav taws xob, cov motors loj, thiab lwm yam, nws yuav tsum tau tso tawm ntau dua 5 feeb kom tso tawm cov nqi them.
(5) Thaum muaj qhov ua tau ntawm inducing electrostatic voltage rau cov khoom siv hluav taws xob nyob ze, nws yuav tsum tau tso tawm los yog luv luv ua ntej.
(6) Rau cov khoom siv hluav taws xob doubler rectifier sib sau ua ke ntawm qhov chaw, nws yog ib qho tsim nyog yuav tsum tau tso tawm cov capacitors ntawm txhua qib ib kauj ruam ua ntej hloov cov xaim lossis tshem tawm cov xaim.
Qhov kev tso tawm tawm yog nyob ntawm qhov ntsuas qhov ntsuas hluav taws xob thiab lub peev xwm ntawm cov khoom ntsuas, thiab yuav tsum muaj qhov muaj peev xwm txaus thiab muaj peev xwm kub.Dej tsis kam yog feem ntau siv, thiab tus nqi kuj yog li ntawm 200-500Ω∕kV.Qhov ntev ntev ntawm ob tus ncej ntawm qhov tawm qhov hluav taws xob tuaj yeem raug xaiv nrog siv rau qhov ntev ntawm cov hluav taws xob tiv thaiv hluav taws xob.Qhov ntev ntawm qhov insulating ib feem ntawm tus pas nrig tawm yuav tsum ua raws li "kev tswj hwm kev nyab xeeb" thiab yuav tsum tsis txhob tsawg dua qhov ntev ntawm cov khoom tawm tawm.

HV HIOPOT GDFR-C series AC thiab DC high voltage voltage divider (sib cais hom)

Qhov tseeb dua ntawm cov koob no yog: AC: 0.5% / DC: 0.5%, yog tias koj xav tau qhov tseeb dua, koj tuaj yeem xaiv peb lub tuam txhab kev ua haujlwm siab, ruaj khov AC standard checker thiab DC checker;
· Txais kev sib npaug equipotential shielding qauv kom nws muaj kev pab cuam lub neej ntev dua thiab ruaj khov dua, thiab muaj feem ntau ntawm kev lag luam thiab kev lag luam lub koob npe nrov hauv daim teb no;
· High precision, siab linearity, siab stability, tiv thaiv kev cuam tshuam;
· Lub tshuab hluav taws xob AC thiab DC tau txais cov khoom ntim tuaj txawv teb chaws, uas ua rau cov qauv me me, sib dua hauv qhov hnyav, siab dua hauv kev ntseeg siab, thiab qis qis hauv ib nrab tawm.
