Kev ntsuas hluav taws xob hluav taws xob hluav taws xob yog ib hom kev ntsuas hluav taws xob siab uas tau ua los txiav txim siab lub peev xwm ntawm cov hluav taws xob hluav taws xob tiv thaiv hluav taws xob. Qhov kev sim no feem ntau yog siv hauv kev lag luam fais fab kom ntseeg tau tias muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov khoom siv hluav taws xob, xws li transformers, switchgear, thiab cables.
Thaum lub sij hawm xeem, ib tug high voltage impulse ntawm lub sij hawm luv luv yog siv rau cov khoom nyob rau hauv kev sim. Lub nthwv dej ntawm lub impulse zoo ib yam li ntawm xob laim tawm tsam, nrog lub sijhawm nrawm nrawm thiab nrawm nrawm. Qhov loj ntawm qhov impulse voltage feem ntau yog txiav txim siab los ntawm chav kawm voltage ntawm cov khoom siv thiab tuaj yeem nyob ntawm ob peb kilovolts mus rau ntau pua kilovolts.
Qhov kev ntsuam xyuas xob laim impulse yog ib kauj ruam tseem ceeb hauv kev txhim kho thiab ntawv pov thawj ntawm cov khoom siv hluav taws xob. Nws pab kom paub tseeb tias cov txheej txheem rwb thaiv tsev tuaj yeem tiv taus qhov kev ntxhov siab ntawm xob laim thiab lwm yam kev kub ntxhov uas yuav tshwm sim thaum lub sijhawm ua haujlwm ib txwm muaj. Qhov kev sim no kuj yog siv los txheeb xyuas qhov tsis muaj zog hauv cov txheej txheem rwb thaiv tsev, xws li voids, tawg, lossis lwm yam tsis xws luag uas yuav cuam tshuam rau kev nyab xeeb thiab kev ntseeg siab ntawm cov khoom siv.
Muaj ntau ntau cov qauv uas tswj kev ntsuas hluav taws xob, suav nrog IEC 60060-1, IEEE 4-1995, thiab ASTM D3755. Cov qauv no muab cov lus qhia rau cov txheej txheem xeem, kev teeb tsa cov cuab yeej, thiab kev ntsuam xyuas cov txiaj ntsig kev xeem. Lawv kuj qhia txog qhov yuav tsum tau ua rau qhov ntsuas qhov ntsuas hluav taws xob, waveform, thiab lub sijhawm, nrog rau cov qauv kev lees paub rau cov khoom siv hauv kev sim.
Ntxiv nrog rau qhov ntsuas hluav taws xob hluav taws xob, muaj lwm hom kev ntsuas hluav taws xob siab uas feem ntau siv hauv kev lag luam hluav taws xob, suav nrog lub zog siv hluav taws xob tiv thaiv kev ntsuas, qhov ntsuas qhov tso tawm ib nrab, thiab kev sim hloov impulse. Txhua qhov kev ntsuam xyuas no muaj nws tus yam ntxwv tshwj xeeb thiab kev siv thiab siv los ntsuas qhov sib txawv ntawm cov khoom siv hluav taws xob.
Kev ntsuas hluav taws xob impulse voltage yog ib qho cuab yeej tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov khoom siv hluav taws xob. Los ntawm kev siv cov cuab yeej siv rau cov khoom siv hluav taws xob siab uas simulate xob laim, qhov kev ntsuam xyuas pab txheeb xyuas qhov tsis muaj zog lossis qhov tsis xws luag hauv cov txheej txheem rwb thaiv tsev uas tuaj yeem ua rau cov khoom tsis ua haujlwm lossis muaj kev nyab xeeb. Yog li ntawd, kev ntsuam xyuas xob laim impulse yog ib qho tseem ceeb ntawm cov txheej txheem kuaj thiab ntawv pov thawj rau cov khoom siv hluav taws xob hauv kev lag luam fais fab.
