Cov Lus Qhia Tseem Ceeb ntawm VLF Kuaj
VLF kev sim feem ntau yog siv rau withstand thiab kuaj mob ntawm nruab nrab {{voltage fais fab cable, siv ib lub teeb liab nrog ntau zaustsawg dua 1 hzLos hloov cov khoom siv li 50/60 hz sim khoom.
Cov kev ntsuas cov khoom tsis sib xws: Feem ntau siv kev lag luam VLF kuaj zaus yog0.1 hz, Txawm hais tias lwm zaus xws li 0.05 hz thiab 0.02 hz kuj tau siv. Kev ntsuas voltages tau txiav txim siab raws li cov cable txoj kev ntsuas ntsuas ntsuas thiab lub hom phiaj ntawm kev xeem (txais lossis txij nkawm).
Kev sim ncua sijhawm: Cov sij hawm xeem tau sib txawv. Rau kev saib xyuas kev kuaj xyuas, ib txwm ua yog15 feeb, thaum cov kev xeem yuav ua tau los ntawm15 txog 60 feeb.
Khoom siv thiab kev nyab xeeb: Cov cuab yeej xeem, feem ntau hu ua aVlf Hipot TesterlossisVLF withstand sim ntaus ntawv, yog tsim los ua portable thiab tag nrho automated. Nco ntsoov ua raws cov qauv kev ua haujlwm tshwj xeeb ntawm kev ua haujlwm thiab ua raws li cov kev ua siab dav dav- voltage kev nyab xeeb kev coj ua hauv kev sim.
Daim Ntawv Thov thiab Kuaj Cov Txheej Txheem
Lub Hom Phiaj Kev Ntsuam Xyuas: VLF kuaj yog siv rauTxais Kev Ntsuam Xyuastom qab teeb tsa kom pom kev puas tsuaj, thiab rauKev saib xyuas thiab kuaj mob kuajThaum lub sijhawm cable system ua haujlwm los ntsuas nws cov xwm txheej thiab nrhiav thaj chaw tsis zoo.
Kuaj cov kev coj ua zoo tshaj plaws:
Npaj Cable Kab Daim Duab thiab Qhia Txog Cov Ntsiab Lus Sib Txuas Ua Ntej Pib.
Yog pom tias muaj qhov ua txhaum thaum lub sijhawm kuaj tiv thaiv, qhov kev txhaum kev nrhiav yuav tsum tau ua.
Tom qab sim ua tiav lossis cuam tshuam, tus qauv ntsuas yuav tsum tau ua si tam sim ntawd rau kev tawm.
Cov lus qhia rau VLF kev sim tuaj yeem sib txawv raws koj cov cuab yeej tshwj xeeb thiab cov cai hauv zos. Rau qhov tseeb tshaj plaws thiab kev nyab xeeb cov txheej txheem, koj yuav tsum tau sab laj tag nrho cov ntawv sau ntawm cov qauv uas muaj feem xyuam nrog koj cov cuab yeej kuaj.
