Litlhoko tsa IEC 61643-31-2018 le mekhoa ea liteko bakeng sa photovoltaic
IEC 61643-31: 2018 e sebetsa ho Lisebelisoa tsa Ts'ireletso ea Surge (SPDs), e reretsoeng ts'ireletso ea ts'ireletso khahlano le litlamorao tse sa tobang le tse tobileng tsa lehalima kapa li-overvoltages tse ling tsa nakoana. Lisebelisoa tsena li etselitsoe hore li hokahane le lehlakore la DC la lisebelisoa tsa photovoltaic tse lekantsoeng ho fihla ho 1 500 V DC. Lisebelisoa tsena li na le bonyane karolo e le 'ngoe e se nang moeli 'me li reretsoe ho fokotsa maqhubu a matla le ho khelosa maqhubu a matla. Litšobotsi tsa ts'ebetso, litlhoko tsa polokeho, mekhoa e tloaelehileng ea liteko le litekanyetso li thehiloe. Li-SPD tse lumellanang le maemo ana li inehetse ka ho khetheha ho kenngoa ka lehlakoreng la DC la lijenereithara tsa photovoltaic le lehlakore la DC la li-inverters. Li-SPD tsa litsamaiso tsa PV tse nang le polokelo ea matla (mohlala, libeteri, libanka tsa capacitor) ha li koaheloe. Li-SPD tse nang le li-terminals tse arohaneng tsa ho kenya le tse hlahisoang tse nang le letoto le ikhethileng lipakeng tsa li-terminal(s) (tse bitsoang li-SPD tse peli ho latela IEC 61643-11: 2011) ha li koaheloe. Li-SPD tse lumellanang le tekanyetso ena li etselitsoe hore li hokahane ka ho sa feleng moo ho hokahanngoa le ho khaola ha SPD e tsitsitseng ho ka etsoang feela ka sesebelisoa. Tekanyetso ena ha e sebetse ho li-SPD tse nkehang habonolo.
