IEC 61643-31-2018 Zvinodiwa uye nzira dzekuyedza dze photovoltaic
IEC 61643-31: 2018 inoshanda kuSurge Protective Devices (SPDs), inoitirwa kuchengetedzwa kwekuzvidzivirira kubva pamhedzisiro isina kunanga uye yakanangana nemheni kana zvimwe zvinopfuura zvenguva pfupi. Aya majaira akagadzirwa kuti abatanidzwe padivi reDC rekuisa mafotovoltaic akayerwa anosvika 1 500 V DC. Midziyo iyi ine kamwechete isiri-mutsara chikamu uye inoitirwa kudzikamisa mavhairasi ekuvhiya uye kushandura mafambiro ekuvhiya. Maitiro ekuita, kuchengetedza zvinodiwa, nzira dzakajairwa dzekuyedza uye zviyero zvinotangwa. MaSPD anoteerana nechiyero ichi akazvipira chete kuiswa padivi reDC remajenareta ephotovoltaic uye DC divi remainverters. SPDs yePV masisitimu ane simba rekuchengetedza (semuenzaniso mabhatiri, capacitor mabhangi) haana kuvharwa. MaSPD ane akapatsanurwa ekuisa uye ekuburitsa zviteshi zvine iwo akanangana akateedzana impedance pakati peaya ma (terminal) (s) anonzi maviri-chiteshi SPDs maererano neIEC 61643-11: 2011) haana kuvharwa. MaSPD anoenderana neichi chiyero akagadzirirwa kuti abatanidzwe zvachose uko kubatana nekubviswa kweiyo yakamisikidzwa SPDs kunogona kuitwa chete uchishandisa chishandiso. Iyi muyero haishande kune anotakurika maPSD.
