Lo lus "HV test" feem ntau yog hais txog High Voltage test, uas yog ib hom kev ntsuas hluav taws xob ua los ntsuas cov hluav taws xob rwb thaiv tsev thiab kev ncaj ncees ntawm cov khoom, cov khoom siv, lossis cov tshuab thaum raug hluav taws xob siab. Qhov ntsuas hluav taws xob siab kuj tseem hu ua dielectric zog kuaj lossis hipot (siab muaj peev xwm) kuaj. Lub hom phiaj ntawm qhov kev sim no yog los xyuas kom meej tias cov rwb thaiv tsev tuaj yeem tiv taus qhov hluav taws xob ntau dua li qub yam tsis muaj kev puas tsuaj lossis tsis ua haujlwm.
Nov yog cov ntsiab lus tseem ceeb ntawm High Voltage test:
Kev ntsuam xyuas Dielectric Strength:
Lub hom phiaj tseem ceeb ntawm kev ntsuas hluav taws xob siab yog los ntsuas lub zog dielectric ntawm cov ntaub ntawv insulating. Lub zog dielectric hais txog lub peev xwm ntawm cov khoom siv los tiv thaiv hluav taws xob tsis muaj kev tawg.
Test Cheebtsam thiab Systems:
Kev ntsuas hluav taws xob siab tuaj yeem ua rau ntau yam khoom siv hluav taws xob, suav nrog cables, transformers, switchgear, circuit breakers, capacitors, thiab lwm yam khoom siv. Lawv kuj tuaj yeem siv rau tag nrho cov tshuab hluav taws xob.
Voltage theem:
Cov qib hluav taws xob siv hauv kev ntsuas hluav taws xob siab yog qhov siab dua li qhov kev ua haujlwm ib txwm muaj hluav taws xob ntawm cov khoom siv. Qhov ntsuas hluav taws xob yog siv rau lub sijhawm teev tseg los ntsuas qhov rwb thaiv tsev lub peev xwm tiv taus hluav taws xob siab.
Hom ntawm High Voltage Tests:
Muaj ob hom kev ntsuas high voltage:
AC High Voltage Test: Hauv qhov kev sim no, ib qho kev hloov pauv tam sim no (AC) voltage yog siv rau lub cuab yeej lossis lub cev. Qhov no pab ntsuam xyuas lub rwb thaiv tsev lub peev xwm los tiv thaiv tsis tu ncua hloov voltages.
DC High Voltage Test: Hauv qhov kev sim no, siv qhov hluav taws xob ncaj qha (DC) voltage. Kev kuaj DC feem ntau yog siv rau cov ntawv thov tshwj xeeb lossis thaum teev los ntawm cov qauv.
Kev kuaj xyuas qhov tsis muaj zog lossis qhov tsis xws luag:
Kev ntsuas hluav taws xob siab yog tsim los txheeb xyuas qhov tsis muaj zog, qhov tsis xws luag, lossis kev tsim khoom tsis raug ntawm lub rwb thaiv tsev. Nws pab txheeb xyuas txhua qhov chaw ntawm rwb thaiv tsev uas tej zaum yuav ua rau tawg nyob rau hauv high voltages.
Ua raws li cov qauv:
Ntau cov qauv hluav taws xob thiab cov cai tswj hwm kev ntsuas hluav taws xob siab rau qee yam khoom siv hluav taws xob. Ua raws li cov qauv no ua kom cov cuab yeej ua tau raws li kev nyab xeeb thiab kev ua haujlwm.
Kev Tiv Thaiv Kev Tiv Thaiv:
Kev ntsuas hluav taws xob siab feem ntau yog ib feem ntawm kev tiv thaiv kev saib xyuas rau cov tshuab hluav taws xob. Kev ntsuam xyuas tsis tu ncua tuaj yeem pab txheeb xyuas cov teeb meem muaj peev xwm ua ntej lawv ua rau kev ua tsis tiav thaum lub sijhawm ua haujlwm tiag tiag.
Rwb thaiv tsev Resistance Measurement:
Ntxiv nrog rau kev ntsuas lub zog dielectric, kev ntsuas kev tiv thaiv hluav taws xob kuj tseem tuaj yeem ua. Rwb thaiv tsev tsis kam yog qhov tsis kam muab los ntawm cov khoom siv rwb thaiv tsev rau qhov ntws ntawm tam sim no.
Kev Tiv Thaiv Kev Nyab Xeeb:
Kev ntsuas hluav taws xob siab muaj feem cuam tshuam txog qhov muaj peev xwm txaus ntshai. Yuav tsum tau ceev faj txog kev nyab xeeb txaus, thiab qhov kev xeem yuav tsum tau ua los ntawm cov neeg ua haujlwm tsim nyog siv cov cuab yeej tsim nyog.
Zuag qhia tag nrho, qhov ntsuas hluav taws xob siab yog qhov tseem ceeb ntawm kev tswj hwm kev ntsuas kom ntseeg tau tias muaj kev nyab xeeb, kev nyab xeeb, thiab ua raws li cov khoom siv hluav taws xob thiab cov tshuab nrog cov qauv kev lag luam thiab cov cai.
