IEC 61643-31: 2018 amadivayisi wokuvikela amandla amancane - Ingxenye 31: Izidingo nezindlela zokuhlola ze-SPDs zokufakwa kwe-photovoltaic

I-IEC 61643-31:2018 isetshenziswa kumadivayisi okuvikela e-Surge (SPDs), okuhloswe ngawo ukuvikela ukuhlinza emiphumeleni engaqondile neqondile yombani noma okunye ukweqisa kwesikhashana. Lawa madivayisi aklanyelwe ukuxhunywa ohlangothini lwe-DC lokufakwa kwe-photovoltaic okulinganiselwe kufika ku-1 500 V DC. Lawa madivayisi aqukethe okungenani ingxenye eyodwa engaqondile futhi ahloselwe ukukhawulela ama-voltage okwandayo futhi ahlukanise ama-surge currents. Izici zokusebenza, izidingo zokuphepha, izindlela ezijwayelekile zokuhlola nezilinganiso ziyasungulwa. Ama-SPD athobelana naleli zinga azinikele ngokukhethekile ekufakweni ohlangothini lwe-DC lwamajeneretha e-photovoltaic kanye nohlangothi lwe-DC lwama-inverters. Ama-SPD amasistimu e-PV anokugcina amandla (isb. amabhethri, amabhange e-capacitor) awamboziwe. Ama-SPD anamatheminali ahlukene okokufaka nokukhiphayo aqukethe i-impedance ethile yochungechunge phakathi kwalezi theminali (okuthiwa ama-SPD anezimbobo ezimbili ngokuya nge-IEC 61643-11:2011) awamboziwe. Ama-SPD athobelana naleli zinga aklanyelwe ukuxhunywa unomphela lapho ukuxhuma nokunqanyulwa kwama-SPD angashintshi kungenziwa kuphela kusetshenziswa ithuluzi. Leli zinga alisebenzi kuma-SPD aphathekayo.
