Xaiv cov khoom siv rausiab -voltage (HV) hloov kub ncekev ntsuam xyuas yog ib qho txheej txheem tseem ceeb uas yuav tsum tau ua tib zoo soj ntsuam cov kev qhia tshwj xeeb, cov qauv, thiab cov kev cai ua haujlwm. Nws yog ib qho kev nqis peev tseem ceeb, uas yuav tsum muaj kev txiav txim siab zoo- ua cov txheej txheem.
Hauv qab no yog cov kauj ruam qhia ntxaws -los ntawm- cov lus qhia kauj ruam los pab koj xaiv cov cuab yeej xeem raug.
Qhov kev xaiv tseem ceeb yuav yog nyob ntawmplaub yam tseem ceeb:
Qhov siab tshaj plaws tam sim no (kA): tus nqi siab tshaj tam sim no uas yuav tsum tau simulated.
Qhov siab tshaj qhov system voltage (kV): qhov ntsuas qhov ntsuas hluav taws xob ntawm qhov hloov pauv tau sim.
Lub sijhawm tam sim no: muaj peev xwm tswj tau qhov tam sim no tsis tu ncua rau lub sijhawm ntsuas ntawm qhov ntsuas (piv txwv li, 4 teev rau lub ntsiab Circuit Court).

Rated tam sim no (Iᵣ):
Dab tsi yog qhov siab tshaj plaws tam sim no muaj peev xwm ntawm lub hwj chim hloov mus kuaj? (eg,2000 A, 3150 A, 4000 A, 6300 A)
Rated luv-circuit tam sim no (Iₛₖ): Qhov ntsuas tam sim no rau lub ntsiab Circuit Court yog qhov ntsuas tam sim no (Iᵣ). Txawm li cas los xij, rau kev sim cov ntsiab lus sib txuas thiab cov khoom siv hluav taws xob, cov qauv xav tau kev siv tam sim no uas ua rau tib lub zog poob raws li qhov ntsuas luv luv -circuit tam sim no. Qhov no yog qhov kev txiav txim siab rau kev ntsuas qhov ua tau zoo ntawm cov cuab yeej ntsuas.
Kev suav cov mis: I_test_connection=I_sk * √ (duty_cycle)
Lub voj voog ua haujlwm feem ntau yog luv luv - lub zog (piv txwv li,1 vib nas this lossis 3 vib nas this). Cov cuab yeej ntsuas yuav tsum muaj peev xwm tsim tau qhov tam sim no siab heev rau lub sijhawm luv luv.
B. Cov qauv siv tau:
Koj cov khoom siv kuaj thiab cov txheej txheem yuav tsum ua raws li cov qauv uas koj lub chaw kuaj mob tau lees paub. Tus qauv tseem ceeb yog:
IEC 62271-1 / IEEE C37.09: Cov hloov hluav taws xob siab thiab tswj cov txheej txheem - Ntu 1: Cov kev cai dav dav
Cov qauv no qhia meej cov txheej txheem, sijhawm, thiab dhau / tsis ua tiav rau kev ntsuas kub nce.
Yam yuav tsum tau muaj: Qhov ntsuas tam sim no yuav tsum ruaj khov nyob rau hauv ±5%thaum kuaj (feem ntau2-4 teevrau lub ntsiab Circuit Court).
C.Test Parameters:
