Lub luag haujlwm tseem ceeb ntawmIb nrab Tso Tawm Induced Resonance Test
Hauv kev sim siab - cov khoom siv hluav taws xob,ib nrab tso tawm induced resonance kuajsawv cev rau ib txoj hauv kev zoo rau kev ntsuam xyuas cov rwb thaiv tsev zoo. Cov txheej txheem no sib txuas cov ntsiab cai ntawm kev kuaj pom ib nrab thiab kev ntsuas resonant zaus los tsim kom muaj kev ntsuas kev ntsuas dav dav rau cov khoom siv hluav taws xob siab -voltage.
Lub luag haujlwm tseem ceeb ntawm qhov kev sim no yog txhawm rau txheeb xyuas qhov cuam tshuam ntawm rwb thaiv tsev nyob rau hauv lub peev xwm thauj khoom-xws li fais fab cables, transformers, thiab generators-los ntawm kev siv lub resonant zaus sib tw rau cov khoom lub ntuj zaus. Piv nrog rau cov kev sim tshuaj ib txwm muaj, qhov no resonant txoj kev ua kom muaj txiaj ntsig zoo ntawm cov khoom siv loj - muaj peev xwm nrog txo kev siv hluav taws xob. Lub xeev resonant tso cai rau qhov kev sim ntsuas kom siv cov qib siab voltage uas yuav tsum tau muaj nrog kev siv hluav taws xob tsawg.
Ib nrab Tso Tawm (PD)-Induced ResonanceKev ntsuam xyuas yog ib qho kev qhia tsis zoo -kev ntsuas kev puas tsuaj uas ua ke nrog lub hwj chim- zaus series resonance test system nrog ib feem ntawm qhov kev ntsuas tawm. Nws lub luag haujlwm tseem ceeb yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau, nws muaj qhov ua tau zoo ntawm cov khoom siv hluav taws xob xwb, nws cov khoom siv hluav taws xob kuj tseem muaj zog ({3}}}voltage (HV)) thiab ntxiv - siab -voltage (EHV)).
Kev ntsuam xyuas kev ruaj ntseg ntawm rwb thaiv tsev los ntawm kev sib txuas ntawm lub zog dielectric nrog kev ua haujlwm tawm ib nrab
Tsis zoo li standalone dielectric zog tests (uas tsuas yog kuaj pom kev puas tsuaj) los yog standalone ib feem ntawm qhov paug tawm (uas yuav siv tsis yog - tus qauv voltage qhov chaw), qhov kev ntsuam xyuas ua ke no ua hauj lwm ob lub hom phiaj:
Kev txheeb xyuas ntawm dielectric zog kev ntseeg tau: Kev lees paub tias cov khoom ntsuas tuaj yeem tiv taus qhov ntsuas qhov ntsuas hluav taws xob rau lub sijhawm teev tseg (piv txwv li, 1 feeb, 10 feeb) yam tsis muaj kev puas tsuaj los yog tawm.
Quantifying qhov hnyav ntawm ib nrab tso tawm: Kev ntsuas ntawm qhov tseem ceeb ntawm qhov tso tawm qhov tsis sib xws (kev tawm hluav taws xob pib [DIV], qhov hluav taws xob tawm hluav taws xob [DEV], kev siv hluav taws xob ntau tshaj plaws, kev tso tawm ntau zaus) txhawm rau ntsuas qhov kev pheej hmoo ntawm kev puas tsuaj. Raws li IEC 60270 tus qauv, piv txwv li, tshiab high -voltage transformers feem ntau xav tau ib feem ntawm qhov kev siv hluav taws xob tsawg dua lossis sib npaug li 10 pC ntawm qhov ntsuas hluav taws xob kom pom tau tias ua raws.
Correlation ntawm voltage thiab tawm voltages: Txheeb xyuas qhov sib txawv ntawm cov dej ntws tawm raws li qhov ntsuas hluav taws xob nce ntxiv (piv txwv li, yog tias qhov kev tawm dag zog nce ntxiv nrog qhov hluav taws xob) txhawm rau ntsuas lub neej muaj peev xwm ntawm cov ntaub ntawv insulating.
Qhov kev ntsuam xyuas resonance feem ntau suav nrog avariable zaus fais fab mov, ibexcitation transformer, thiabib tug resonance Circuit Court.Thaum lub kaw lus mus txog qhov zaus resonant, nws tsim cov xwm txheej tsim nyog los cuam tshuam ib feem ntawm qhov cuam tshuam ntawm cov rwb thaiv tsev uas twb muaj lawm. Cov cuab yeej tshwj xeeb ib feem tso tawm kom pom tau saib xyuas thiab sau cov qauv tawm, muab cov ntaub ntawv tseem ceeb ntawm cov xwm txheej ntawm cov rwb thaiv tsev.
Txoj kev sim no muaj ntau yam kev ua haujlwm zoo, xws li lub peev xwm los ntsuas cov cuab yeej hauv kev ua haujlwm tiag tiag, txhim kho rhiab heev hauv kev ntsuas qhov tso tawm ib nrab, thiab txo lub cev kev ntxhov siab ntawm lub rwb thaiv tsev thaum kuaj. Txoj kev sib koom ua ke zaus kuj tseem pab kom paub qhov txawv ntawm ntau hom kev tso tawm ib nrab thiab muab cov ntaub ntawv ntxaws ntxaws ntxiv rau kev txiav txim siab txij nkawm- ua.
