Uxhulumaniso lwe-Equipotential kwiinkqubo ze-photovoltaic Izixhobo ezisezantsi kunye nabaqhubi abakhuselayo kwiinkqubo ze-photovoltaic ziya kuhambelana ne-IEC60364-7-712: 2017, enika ulwazi olongezelelweyo. Ubuncinci becandelo lomnqamlezo we-equipotential bonding strip kufuneka lihlangabezane neemfuno ze-IEC60364-5-54, IEC61643-12 kunye ne-GB/T21714.3-2015. Ukuba i-equipotential bonding strips isetyenziswa njengabaqhubi abaphantsi, indawo yabo encinci ye-cross-sectional kufuneka ibe yimicingo yobhedu ye-50mm, okanye i-curry-carrying capacity conductors efanayo. Ukuba umtya we-equipotential bonding kulindeleke ukuba uqhube umbane ngoku, ubuncinci indawo yawo enqamlezayo kufuneka ibe yi-16mm yocingo lwephini, okanye umthamo olinganayo wangoku. umqhubi. If the equipotential bonding strip is expected to conduct only induced lightning current, its minimum cross-sectional area shall be 6mm copper wire or equivalent current-carrying capacity umqhubi. Ubuncinci bommandla onqamlezileyo womqhubi odibanisayo odibanisa iindawo eziqhubayo kumgca we-equipotential bonding iya kuba yi-6mm ucingo lobhedu, okanye umthamo olinganayo wokuthwala wangoku. umqhubi. Ngokungabikho kwenkqubo ye-photovoltaic eqhagamshelwe kwinkqubo yokukhusela umbane, ubuncinci bendawo enqamlezayo yabaqhubi abaqhagamshelayo abaqhagamshelwe kwiintambo ezahlukeneyo zokudibanisa kunye nee-conductor eziqhagamshelwe kwinkqubo yokumisa kufuneka ibe yi-6mm yocingo lobhedu, okanye ngokulinganayo ngoku- ukuthwala umthamo wabaqhubi. Qaphela: Ezona mfuno zisezantsi zomnqamlezo kubancedisi ziyahluka kwamanye amazwe. Ezi zintlukwano zichazwe kwi-GB / T 217143-2015. Inxalenye ye-LPS ekulindeleke ukuba ihambe inxalenye yombane wangoku kufuneka ihambelane ne-IEC 62561 (zonke iindawo). Xa inkqubo ye-photovoltaic ikhuselwe yinkqubo yokukhusela umbane, umgama omncinci okhuselekileyo wokuhlukana kufuneka ugcinwe phakathi kwenkqubo yokukhusela umbane kunye nezakhiwo zetsimbi zenkqubo ye-photovoltaic ukukhusela inxalenye yombane wangoku ukuba uqhubele kwezi zakhiwo. Ubuncinci bommandla onqamlezileyo wabo bonke abaqhubi be-equipotential bonding yi-6mm, ngaphandle kwabaqhubi abasemhlabeni beklasi I surge abakhuseli kwikhabhinethi engundoqo yokusabalalisa. Ukuba iimodyuli ze-photovoltaic zikhuselwe yinkqubo yokukhusela umbane kodwa umgama okhuselekileyo wokuhlukana awukwazi ukugcinwa phakathi kwezi zibini, uxhulumaniso oluthe ngqo lufanele longezwe phakathi kwenkqubo yokukhusela umbane wangaphandle kunye nesakhiwo sesinyithi se-photovoltaic array. Olu xhulumaniso lufanele lukwazi ukumelana nombane othile wangoku. Ubuncinci bommandla onqamlezileyo we-equipotential bonding conductor uya kuhlangabezana neemfuno ze-IEC60364-5-541EC61643-12 kunye ne-GB/T217143-2015. Ubuncinci bommandla onqamlezileyo kuzo zonke iikhondaktha ze-equipotential bonding ziya kuba yi-16mm, ngaphandle kweentambo ze-equipotential bonding zokumisa i-inverter.
